The acquisition expandsindustries.

CombiMatrix Group Split-off Transaction and diversifiesRelated Discontinued Operations. In January 2006, Acacia Research Corporation’s board of directors approved a plan for its wholly owned subsidiary, CombiMatrix Corporation, the primary component of Acacia Technologies group's revenue generating opportunitiesResearch Corporation’s CombiMatrix group, to become an independent public company.  CombiMatrix Corporation’s registration statement on Form S-1 was declared effective by the Securities and acceleratesExchange Commission (“SEC”) on June 8, 2007.  Following the executionredemption period required by Acacia Research Corporation’s Restated Certificate of Incorporation, on August 15, 2007 (the “Redemption Date”), CombiMatrix Corporation was split-off from Acacia Research Corporation through the redemption of all outstanding shares of Acacia Research-CombiMatrix common stock in exchange for  the distribution of new shares of CombiMatrix Corporation common stock, on a pro-rata basis, to the holders of Acacia Research-CombiMatrix common stock on the Redemption Date (the “Split-off Transaction”). On the Redemption Date, every ten (10) shares of Acacia Research-CombiMatrix common stock outstanding on August 15, 2007, was redeemed for one (1) share of common stock of CombiMatrix Corporation.  Subsequent to the Redemption Date, Acacia Research Corporation no longer owns any equity interests in CombiMatrix Corporation and the two companies operate independently of each other.

As a result of the Acacia Technologies group's business strategySplit-off Transaction, we have disposed of acquiring, developing and licensing patented technologies.our investment in CombiMatrix Corporation.  Refer to Note 16 in10A to the accompanying Acacia Research Corporation consolidated financial statements, included elsewhere herein, for financial information relatedregarding presentation of the assets, liabilities, results of operations and cash flows for the CombiMatrix group as “Discontinued Operations,” for all periods presented, in accordance with guidance set forth in SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”).

Capital Structure

As a result of the Split-off Transaction, Acacia Research Corporation no longer owns any equity interests in CombiMatrix Corporation and the CombiMatrix group is no longer a business group of Acacia Research Corporation.  Pursuant to ourthe terms of the Split-off Transaction, all outstanding shares of Acacia Research-CombiMatrix common stock were redeemed, and hence, all rights of holders of Acacia Research-CombiMatrix common stock ceased as of the Redemption Date, except for the right, upon the surrender to the exchange agent of shares of Acacia Research-CombiMatrix common stock, to receive new shares of CombiMatrix Corporation stock pursuant to the exchange ratio described above.  Subsequent to the consummation of the Split-off Transaction, Acacia Research Corporation’s only class of common stock outstanding is its Acacia Research-Acacia Technologies common stock.

Prior to the Split-off Transaction, Acacia Research Corporation had two segments. RECAPITALIZATION AND MERGER TRANSACTIONS On December 11, 2002, our stockholders voted in favor of a recapitalization transaction, which became effective on December 13, 2002, whereby we created two new classes of common stock called Acacia Research-CombiMatrix stock, or AR-CombiMatrix stock, andoutstanding, its Acacia Research-Acacia Technologies common stock or(“AR-Acacia Technologies stock”) and its Acacia Research-CombiMatrix common stock (“AR-CombiMatrix stock”).  AR-Acacia Technologies stock and divided our existing Acacia Research Corporation common stock into shares of the two new classes of common stock. AR-CombiMatrix stock iswas intended to reflect separately the performance of Acacia Research Corporation's CombiMatrixCorporation’s Acacia Technologies group.  AR-Acacia TechnologiesAR-CombiMatrix stock iswas intended to reflect separately the performance of Acacia Research Corporation's Acacia TechnologiesCorporation’s CombiMatrix group.  Although the AR-CombiMatrix stock and the AR-Acacia Technologies stock areand the AR-CombiMatrix stock were intended to reflect the performance of our different business groups, they arewere both classes of common stock of Acacia Research Corporation and arewere not stock issued by the respective groups. As

Our Board of Directors has approved an amendment and restatement of our certificate of incorporation to remove reference to AR-CombiMatrix stock which was cancelled as a result holders of Acacia Research-Acaciathe redemption, to rename AR-Acacia Technologies stock as the only class of common stock, and Acacia Research-CombiMatrixto provide that all 100,000,000 shares of AR-Acacia Technologies stock continuecurrently authorized may be issued as a single class of common stock.  The amendment and restatement of our certificate of incorporation is subject to approval by the stockholders at the next annual meeting of stockholders, as further described in our proxy statement to be subject to all of the risks of an investment in Acacia Research Corporation and all of its businesses, assets and liabilities. The assets Acacia Research Corporation attributes to one group could be subject to the liabilities of the other group. Included in the CombiMatrix group and the Acacia Technologies group are certain wholly owned subsidiaries that are not material, quantitatively or qualitatively, either individually or in the aggregate, to either group, or to Acacia Research Corporation as a whole. On December 13, 2002, Acacia Research Corporation acquired the stockholder interests in CombiMatrix Corporation not already owned by us (52% of the total stockholder interests in CombiMatrix Corporation). The acquisition was accomplished through a merger in which stockholders of CombiMatrix Corporation other than Acacia Research Corporation received one share of the new AR-CombiMatrix stock in exchange forfiled.  If adopted, each share of CombiMatrix Corporation common stock that they owned immediately priorwill be entitled to one vote and the merger. OTHER relative voting strength of the common stock will be equal notwithstanding the trading price of the common stock.

Intellectual Property Licensing Business

Acacia Research Corporation’s operating subsidiaries acquire, develop, license and enforce patented technologies.  Our operating subsidiaries generate license fee revenues and related cash flows from the granting of licenses for the use of patented technologies that our operating subsidiaries own or control.  Our operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, if necessary, with the enforcement against unauthorized users of their patented technologies. Currently, on a consolidated basis, our operating subsidiaries own or control the rights to 91 patent portfolios, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.  Our operating subsidiaries have established a track record of licensing success with more than 540 license agreements executed to date.  Our professional staff includes in-house patent attorneys, licensing executives, engineers and business development executives.

Our clients are primarily individual inventors and small companies who have limited resources and/or expertise to effectively address the unauthorized use of their patented technologies, and also include large companies seeking to effectively and efficiently monetize their portfolio of patented technologies. In a typical client arrangement, our operating subsidiary will acquire a patent portfolio, or acquire rights to a patent portfolio, with our clients receiving an upfront payment for the purchase of the patent portfolio or patent portfolio rights, or receiving a percentage of our operating subsidiaries net recoveries from the licensing and enforcement of the patent portfolio, or a combination of the two.

In January 2005, our wholly owned subsidiary, CombiMatrix Corporation and CombiMatrix Corporation's wholly owned subsidiary, CombiMatrix K.K. The CombiMatrix group is seeking to become a broadly diversified biotechnology company, through the development of proprietary technologies and products in the areas of drug development, genetic analysis, nanotechnology research, defense and homeland security markets, as well as other potential markets where its products could be utilized. Among the technologies being developed by the CombiMatrix group are a platform technology to rapidly produce customizable arrays, which are semiconductor-based tools for use in identifying and determining the roles of genes, gene mutations and proteins. This technology has a wide range of potential applications in the areas of genomics, proteomics, biosensors, drug discovery, drug development, diagnostics, combinatorial chemistry, material sciences and nanotechnology. Other technologies include proprietary molecular synthesis and screening methods for the discovery of potential new drugs. TECHNOLOGIES SEMICONDUCTOR BASED ARRAY The CombiMatrix group's semiconductor based array technology enables the rapid, parallel synthesis, immobilization and detection of molecules and materials at discrete electrodes on a semiconductor chip. These chips, also known as microelectrode arrays, are used in multiple applications in the areas described above. The CombiMatrix group's technology integrates semiconductor micro fabrication, proprietary software, chemistry and hardware into systems that it believes will enable it, its customers and its partners to design and fabricate arrays for biological, diagnostic, material sciences and nanotechnology applications, typically within a few days. The CombiMatrix group's system should enable researchers to conduct rapid, iterative experiments in each of these fields. For biological applications, the CombiMatrix group believes that its customizable arrays will enable users to reduce the time and costs associated with the discovery and development of pharmaceutical products. Although there are numerous applications of the CombiMatrix group's arrays in life sciences research, each depend on the synthesis, immobilization or detection of molecules at discrete sites on the array. Some specific applications include studies of genetic expression in cellular systems, genotyping and mutation analysis, synthesis of nucleic acid drugs, and others. Utilizing this array technology, the CombiMatrix group is engaged in four strategic business areas: o The development, manufacture and sale of research tools and services to life sciences researchers o The discovery of drugs based on the mechanism of ribonucleic acid inhibition, or RNAi, and other approaches o The development, manufacture and sale of biosensor systems and technology for national defense and homeland security o The development of tools for applications in nanotechnology and materials science. ELECTROCHEMICAL SYNTHESIS OF MOLECULES The CombiMatrix group is utilizing its expertise in electrochemistry to synthesize novel compounds, which can be screened in binding and cellular assays to determine their potential as new drugs. The types of molecules that can be synthesized electrochemically from precursors using various approaches, proprietary to the CombiMatrix group, include organic compounds, nucleic acids, peptides and others. These molecules can then be utilized in biochemical and cellular screens to determine if they have appropriate potency to be considered for downstream pre-clinical and clinical drug development. 3 POTENTIAL DRUG COMPOUNDS Through its minority investment in Leuchemix, Inc., the CombiMatrix group has access to proprietary compounds that have been shown to be cytotoxic towards certain cancers in vitro and in vivo. Many of these compounds were discovered through combinatorial chemistry, natural product chemistry and certain cellular screening assays. Leuchemix, Inc. has access to state of the art laboratories and equipment, which includes flow cytometry, molecular biology and cell culture facilities. In addition, Leuchemix, Inc. has access to a bank of over 150 primary leukemia specimens and a panel of 15 leukemia and lymphoma cell lines as well as several xenogenic animal model systems. MARKET OVERVIEW The markets for the CombiMatrix group's products include pharmaceutical and biotechnology markets (also referred to as life sciences), national defense and homeland security applications and the emerging markets for nanotechnology and new materials. In the future, if the CombiMatrix group is successful in developing approved drugs either internally or through its investments in companies such as Leuchemix, Inc., the CombiMatrix group's market opportunities will expand to include pharmacies, physicians, hospitals, patients and other consumers of therapeutics. At this time, the majority of the CombiMatrix group's efforts are focused on the life sciences and national defense markets. GENERAL OVERVIEW OF LIFE SCIENCES AND PHARMACEUTICAL INDUSTRIES The pharmaceutical and biotechnology industries are faced with increasing costs and risks of failure in the drug discovery, development and commercialization process. According to industry statistics, the time required to commercialize a new drug averages 15 years. Declining research and development productivity, rising costs of commercialization, increasing reimbursement influence and shorter exclusivity periods have driven up the cost to develop each successful compound to $1.7 billion according to recent industry data. Only one compound now reaches the market for every thirteen discovered and placed in preclinical trials, compared to one for every eight between 1995 and 2000. The pharmaceutical and biotechnology industries are working to reduce their costs and risks of failure by turning to new technologies to help identify deficiencies in drug candidates as early as possible in the process so that drug discovery and development become more efficient and cost-effective. Additionally, with vast amounts of genomic data becoming available for use in the development of therapeutics and diagnostic tests, they are searching for ways to expedite their analysis of available genomic data so that they can be the first to bring new therapeutics and diagnostic tests to market. DRUG DISCOVERY AND DEVELOPMENT The discovery and development of new drugs for a particular disease typically involves several steps. First, researchers identify a target for therapeutic intervention, such as a protein or gene, that is either directly involved in the disease or lies in a biochemical pathway leading to the disease. The next step is to identify chemical compounds that interact with and modulate the target's activity to inhibit or prevent the disease. Promising compounds advance to subsequent stages, which include animal trials followed by human trials. Recent advances, including the sequencing of the human genome, have led to the use of genomics in choosing and validating the targets for drug development. This process begins with the discovery and identification of genes within the genome and the functions of these genes in regulating biological processes and disease. This information is used to assess the value of a particular gene or its protein product as a target for drug discovery. According to industry statistics, pharmaceutical and biotechnology companies worldwide spent approximately $62.0 billion on drug research and development during 2003. GENES AND PROTEINS The human body is composed of billions of cells each containing DNA that encodes the basic instructions for cellular function. The complete set of an individual's DNA is called the genome, and is organized into 23 pairs of chromosomes, which are further divided into smaller regions called genes. Each gene is composed of a strand of four types of nucleotide bases, referred to as A, C, G and T. The bases of one DNA strand bind to the bases of the other strand in a specific fashion to form base pairs: the base A always binds with the base T and the base G always binds with the base C. The human genome has approximately 3.0 billion nucleotides and their precise order is known as the DNA sequence. When a gene is turned on, or expressed, the genetic information encoded in the DNA is copied to a specific type of RNA, called messenger RNA, or mRNA. The mRNA provides instructions for the synthesis of proteins. Proteins direct cellular function, the development of individual traits and are involved in many diseases. Abnormal variations in the sequence of a gene or in the level of gene expression can interfere with the normal physiology of particular cells and lead to a disease, a predisposition to a disease or an adverse response to drugs. 4 GENE EXPRESSION PROFILING Gene expression profiling is the process of determining which genes are active in a specific cell or group of cells and is accomplished by measuring mRNA, the intermediary between genes and proteins. By comparing gene expression patterns between cells from normal tissue and cells from diseased tissue, researchers may identify specific genes or groups of genes that play a role in the presence of disease. Studies of this type, used in drug discovery, require monitoring thousands, and preferably tens of thousands, of mRNAs in large numbers of samples. As the correlation between gene expression patterns and specific diseases is determined, the CombiMatrix group believes that gene expression profiling will have an increasingly important role as a diagnostic tool. Diagnostic use of expression profiling tools is anticipated to grow rapidly with the combination of the sequencing of various genomes and the availability of more cost-effective technologies. GENETIC VARIATION AND MUTATIONS Genetic variation is also due to polymorphisms (mutations) in genomes, although functional variations may also arise from differences in the way genes are expressed in a given cell, as well as the timing and levels of their expression. The most common form of genetic variation occurs as a result of a difference in a single nucleotide in the DNA sequence, commonly referred to as a single nucleotide polymorphism, or SNP. The human genome is estimated to contain between three and six million SNPs. By screening for polymorphisms, researchers seek to correlate variability in the sequence of genes with a specific disease. SNPs are believed to be associated with a large number of human diseases, although most SNPs are believed to be benign and not to be associated with disease. Determining which SNPs may be related to a disease is a complex process requiring investigation of a vast number of SNPs. A SNP association study might require testing for 200,000 possible SNPs in 1,000 patients. Although only a few hundred of these SNPs might be clinically relevant, 200 million genotyping tests, or assays, might be required to complete a study. Using currently available technologies, this scale of SNP genotyping is both impractical and prohibitively expensive. While in some cases one SNP will be responsible for medically important effects, it is now believed that the genetic component of most major diseases is associated with a combination of SNPs. As a result, the scientific community has recognized the importance of investigating combinations of many SNPs in an attempt to discover medically valuable information. In order to understand how genetic variation causes disease, researchers must compare gene sequence polymorphisms, or conduct SNP genotyping, from healthy and diseased individuals. Researchers may also compare gene expression patterns, or perform gene expression profiling, from healthy and diseased tissues. PROTEOMICS Proteomics is the process of determining which proteins are present in cells, how they interact with one another and how they are correlated with genomic variation. This process is useful in drug discovery and diagnostics because most drugs target proteins that play a role in the existence or development of a disease. CURRENT TECHNOLOGIES Despite the recent sequencing of the human genome, scientists have a limited understanding of the function of genes, how they interact with each other, how they modulate disease, and how they correlate with protein translation and function. Additionally, the role of specific mutations is poorly understood. Traditional technologies for analyzing genetic or protein variation and function generally perform experiments individually, or serially, and often require relatively large sample volumes, adding significantly to the cost of conducting experiments. Arrays were developed to overcome the limitations of traditional technologies and enable the parallel evaluation of large numbers of genes. An array is a collection of miniaturized test sites arranged in a manner that permits many tests to be performed simultaneously, or in parallel, in order to achieve higher throughput. The average size of test sites in an array and the spacing between them defines the array's density. Higher density increases parallel processing throughput. In addition to increasing the throughput, higher density reduces the required volume for the sample being tested, and thereby lowers costs. Currently, the principal commercially available ways to produce arrays include mechanical deposition, bead immobilization, inkjet printing and photolithography. While current array technologies have revolutionized drug discovery and development, the CombiMatrix group believes that it's advanced array technology provides characteristics, including flexibility, superior cost metrics, and performance which address certain needs of the life sciences market which are not addressed by conventional arrays. 5 THE COMBIMATRIX SOLUTION The CombiMatrix group believes that its system will have advantages over other existing technologies because it is being designed to be a cost-effective, fast, flexible, customizable alternative to existing analytical tools designed for similar purposes. Researchers using the CombiMatrix group's system should be able to design and order custom arrays, conduct their tests, analyze the results, and reorder additional arrays incorporating modified test parameters, all within a few days. The CombiMatrix group believes that its system will offer several important advantages over competing products. These advantages arise from a unique approach to fabricating the arrays utilizing a proprietary electrochemical synthesis method on an array of microelectrodes that have been fabricated on a silicon device. GENETIC ANALYSIS PRODUCTS AND SERVICES The CombiMatrix group's technology represents a significant advance over existing array technologies and other platforms for combinatorial chemistry. The first application of the technology that the CombiMatrix group is pursuing is in the field of genomics, where it is developing an array for the analysis of DNA. The CombiMatrix group believes that this technology may be applied to the fields of genetic analysis and disease management. CUSTOMARRAY(TM) The CombiMatrix group's product for genetic studies is marketed under the trade name CustomArray(TM). CustomArray(TM) is a highly flexible custom oligonucleotide array that addresses researchers' specific requirements for high-performance arrays that can interrogate small sets of target genes or whole genomes at a low cost. CustomArrays currently come in two formats: the lower-density CustomArray(TM) 902, and the medium-density CustomArray(TM) 12K. The CustomArray(TM) 902 enables an analysis of roughly 1,000 genes, and the CustomArray(TM) 12K enables analysis of up to 12,000 genes. CustomArray(TM) is an advanced tool used to understand gene expression by measuring mRNA activity within a cell type or groups of cells, enabling researchers to understand disease, predisposition to disease, drug response and drug development. CustomArray(TM) can also be used as a SNP genotyping tool providing statistics on the effect of a SNP or groups of SNPs, giving rise to data that is important in diagnostic testing. Because of the product's flexibility, researchers have utilized and are evaluating the use of CustomArrays for other applications such as gene assembly, sequencing, protein translation and others. ON-LINE ORDER PROCESSING AND SOFTWARE TOOLS CustomArrays are designed and ordered through the CombiMatrix group's on-line ordering process. Customers are able to utilize a number of tools to design and order their arrays through an on-line interface via the World Wide Web. Some of the tools available to the customers are referred to as the CustomArray(TM) content software application suite of tools for designing and ordering arrays. The content software application provides a suite of sophisticated tools that customers can use to design a custom array specific to their experimental needs. This application allows the customer to submit a list of genes and/or genomic sequences to the CombiMatrix group's probe design system. This design process produces probe sequences optimal to the customer's requirements. Customers also have the flexibility to re-design their array at anytime. When the customer has finished designing their arrays using the CombiMatrix group's proprietary software tools, the arrays may be ordered using the e-commerce section of the CustomArray(TM) web site. Arrays are then manufactured using our proprietary oligonucleotide synthesis technology to the specific design requirements of the customer's order. The CombiMatrix group's proprietary DNA synthesis technology enables product turnaround time of typically just a few days. After production, each array is put through a rigorous quality control process. To our knowledge, the CombiMatrix group is the only array company that quality checks every single feature on each array produced prior to shipment. DESIGN-ON-DEMAND(TM) The CombiMatrix group has also launched a service known as Design-on-Demand(TM) for its arrays. Through this service, customers can work one-on-one with our staff of bioinformatic experts to assist them with designing their arrays to meet their specific project goals. Customers can also access our Design-on-Demand(TM) catalog of over 1,400 pre-designed genome arrays available for ordering. 6 HOMELAND SECURITY AND DEFENSE APPLICATIONS Through U.S. government funding, the CombiMatrix group's array technology is being developed to simultaneously detect toxins, viruses, and bacteria using either genomic analysis or antigen-antibody experiments, or assays. The ability to conduct over 12,000 individual assays simultaneously means that the CombiMatrix group's array can be configured to detect many biothreat agents of interest to the U.S. Department of Defense and Department of Homeland Security within hours and with a high degree of certainty that surpasses current technologies. The CombiMatrix group's goal is that these systems will eventually be portable and ultimately be completely automated. The CombiMatrix group's technology can simultaneously identify hundreds of different microbes (including viruses), determine their ability to cause disease, and discover their characteristics, such as antibiotic resistance. Working with academia, industry, and government laboratories, the CombiMatrix group is developing assays, arrays and bioinformatics for quickly identifying human, animal, and plant pathogens in a single-assay format. This format and single test eliminates the need for a different test for each disease or threat and eliminates the time lost in developing a new test for each new disease or threat. For disease-control agencies, it simplifies the process, reduces costs, and allows more rapid identification and reaction, all in an environment where increased time can equate to increased illness and loss of lives. This program is enabled by the characteristic of the CombiMatrix group's array technology, which allows the binding reactions to be measured through electrochemical means instead of optical methods. Though optical detection has been successful in many applications and our other products utilize these methods, we feel that electrochemical detection techniques have the potential to be far superior. By eliminating the need for light sources, optical components, their corresponding mechanical requirements as well as their power requirements, we feel that we will be able to build detection systems that will be less expensive, smaller, lighter and portable. In addition, certain technical characteristics of electrochemical detection on the arrays may enable higher sensitivity, better dynamic range and superior reproducibility in measurements. Though the initial focus of our Government-funded development program is a product for military and homeland security markets, the core technology being developed will be applicable to products in the life sciences and human healthcare markets as well. DRUG DISCOVERY The CombiMatrix group has initiated both internally focused and externally focused programs to utilize its arrays to discover nucleic acid drugs, based on the recently discovered mechanism known as RNAi (Ribonucleic Acid interference). This field is often referred to as siRNA (small interfering Ribonucleic Acid) or gene silencing. The underlying principle in this field is that an appropriately designed, double-stranded sequence of RNA can effectively shut down the operation of a particular gene. If this inhibition cures a disease or alleviates its symptoms, these RNA molecules can potentially become effective therapeutics. The process of drug discovery utilizing the RNAi mechanism involves multiple steps, the first of which is the design and synthesis of potential RNAi sequences. The CombiMatrix group believes that its expertise in nucleic acid design and synthesis on its semiconductor-based arrays provides a significant advantage in discovery. The CombiMatrix group has chosen to initially focus its integrated RNAi discovery program on viral diseases for the following reasons: o Viral infections affect millions of individuals throughout the world each year o There are relatively few effective anti-viral medications o Most emerging diseases are viruses such as SARS and West Nile Virus o The basis of infection is through transfer of viral genetic material o Complete viral genomic sequences have recently been made available o The CombiMatrix group's approach is suited to viral research because it attempts to thwart a virus by building a cocktail of drugs to target multiple genes or all the genes of a virus o It is believed that an RNAi effect is already operating when the body battles viral infections 7 NANOTECHNOLOGY The CombiMatrix group has also entered into development programs to use its arrays for the discovery of nano-structured materials. In analogy to the study of genes and proteins in parallel using a highly-customizable array, the CombiMatrix group will develop a system, which enables researchers to perform combinatorial materials discovery work in a rapid, cost effective manner. THE COMBIMATRIX GROUP'S STRATEGY FOCUSING ON HIGH-GROWTH MARKETS The CombiMatrix group's goal is to provide customers and partners with tools in their discovery efforts as well as to perform discovery itself. The CombiMatrix group will focus on markets that it believes are growing rapidly and where it believes it has a competitive advantage. The first of these markets are for gene expression, mutation analysis, and other applications for the development of drugs and diagnostic products. Other markets include protein analysis, homeland security and military applications, anti-viral drug development nanotechnology and material sciences. PARTNERING WITH MULTIPLE COMPANIES TO EXPAND MARKET OPPORTUNITY The CombiMatrix group plans to pursue multiple relationships to facilitate the expansion of its array technologies and to exploit large and diverse markets. The CombiMatrix group expects to enter into relationships and collaborations to gain access to complementary technologies, distribution channels, manufacturing infrastructure and information content. The CombiMatrix group intends to structure relationships that maximize its research and development efforts with the strong distribution and manufacturing capabilities of its customers and any entities with which the CombiMatrix group has joint development efforts. MAJOR STRATEGIC ALLIANCES The CombiMatrix group intends to rapidly commercialize its array technology for gene expression profiling through its own sales and marketing efforts. In addition, the CombiMatrix group has had agreements with several strategic partners, such as Roche Diagnostics GmbH, or Roche, to jointly develop its technology. For example, Roche contributed extensive expertise in the areas of instrument and reagent development, and offers a large and experienced worldwide sales and marketing team. The CombiMatrix group believes that the combination of its array technology with Roche's leadership position in the genetic analysis and diagnostic markets will enable it to capture a significant portion of the gene expression profiling and molecular diagnostic markets. The CombiMatrix group has been awarded several U.S. government grants and contracts to develop its electrochemical detection system for the detection of biological threat agents. Though these programs initially focused on product development for military and homeland security applications, the CombiMatrix group believes that the core technology being developed will be applicable to products in the life sciences and human healthcare markets as well. The CombiMatrix group has also entered into a design, fabrication and manufacturing relationship with Toppan Printing of Japan, or Toppan, and Furuno Electronic Co., or Furuno, for the development and manufacture of new designs of its electrochemical detection arrays and bench-top array synthesizers, respectively. In addition to these relationships, the CombiMatrix group has entered into additional relationships and plans on establishing other relationships for multiple applications of its technology. EXPANDING TECHNOLOGIES INTO MULTIPLE PRODUCT LINES The CombiMatrix group intends to utilize the flexibility of its semiconductor based array technologies to develop multiple product lines. In addition to providing new sources of revenue, it believes these product lines will further its goal of establishing its array technology as the industry standard for array-based analysis. 8 STRENGTHENING TECHNOLOGICAL LEADERSHIP The CombiMatrix group plans to continue advancing its proprietary technologies through its internal research efforts, collaborations with industry leaders and strategic licensing. The CombiMatrix group may also pursue acquisitions of complementary technologies and leverage its technologies into other value-added businesses. PROTECTING AND STRENGTHENING INTELLECTUAL PROPERTY Through the CombiMatrix Corporation's four patents issued in the United States and three corresponding patents granted in Europe, Australia and Taiwan, its 59 patent applications pending in the United States, Europe and elsewhere and its trade secrets, the CombiMatrix group believes it has suitable intellectual property protection for its proprietary technologies in those markets where it operates and where a market for its products and services exists. The CombiMatrix group plans to build its intellectual property portfolio through internal research efforts, collaborations with industry leaders, strategic licensing and possible acquisitions of complementary technologies. The CombiMatrix group also plans to pursue patent protection for downstream products created using its proprietary products. REGULATORY MATTERS The CombiMatrix group sells array products to the pharmaceutical, biotechnology and academic communities for research applications as well as non-life sciences customers. In addition, its drug development efforts are early stage. Therefore, its initial products do not require approval from, or be regulated by, the FDA, as a manufacturer nor are they subject to the FDA's current good manufacturing practice, or cGMP, regulations. Additionally, the CombiMatrix group's initial products are not subject to certain reagent regulations promulgated by the FDA. However, the manufacture, marketing and sale of certain products and services for most clinical or diagnostic applications will be subject to extensive government regulation as medical devices in the United States by the FDA and in other countries by corresponding foreign regulatory authorities. SUBSIDIARIES Prior to July 11, 2003, CombiMatrix K.K., a majority-owned subsidiary of CombiMatrix Corporation, was operating under a joint venture agreement with Marubeni Japan, or Marubeni, one of Japan's leading trading companies. The primary purpose of the joint venture was to focus on development and licensing opportunities for CombiMatrix Corporation's array technology with academic, pharmaceutical and biotechnology organizations in the Japanese market. Marubeni held a 10% minority interests in the joint venture. On July 11, 2003, Acacia Research Corporation purchased the outstanding minority interests in CombiMatrix K.K. from Marubeni. Acacia Research Corporation issued 200,000 shares of its AR-CombiMatrix stock to Marubeni in exchange for Marubeni's 10% minority interests in CombiMatrix K.K. This increase in ownership interest has been attributed to the CombiMatrix group. Prior to July 2, 2003, CombiMatrix Corporation owned 87% of Advanced Material Sciences, which in turn holds an exclusive license for CombiMatrix Corporation's array synthesis technology for the development and discovery of advanced electronic materials for such purposes as fuel cell catalysts. In consideration for this exclusive license, CombiMatrix Corporation will share in the revenues earned by Advanced Material Sciences for commercialization of these discoveries based on CombiMatrix Corporation's array technology. The term of this arrangement is 20 years. On July 2, 2003, Acacia Research Corporation increased its consolidated ownership interest in Advanced Material Sciences to 99% by acquiring 1,774,750 shares of Advanced Material Sciences common stock in exchange for 295,790 shares of AR-CombiMatrix stock. This increased ownership interest has been attributed to the CombiMatrix group. MARKETING AND DISTRIBUTION During 2004, the CombiMatrix group launched its CustomArray(TM) products and is currently selling these products directly and through distributors to customers in the United States, Australia, New Zealand and Japan. Where appropriate, the CombiMatrix group will continue to market and sell its products directly or through distribution arrangements and/or through other strategic alliances. In July 2001, CombiMatrix Corporation entered into non-exclusive worldwide license, supply, research and development agreements with Roche. These agreements were amended in September 2002, primarily to grant Roche manufacturing rights with respect to the products under development in return for additional cash consideration under the agreements. The revised agreements also made minor modifications to terms of the agreements involving matters such as milestones, payments and technical specifications, none of which were considered to be material. Such minor modifications are a standard part of the research and development process and in our experience are routinely made in development agreements. 9 In March 2004, the agreements were modified to indicate that CombiMatrix Corporation had completed all phases of its research and development commitments to Roche. Since the inception of our relationship with Roche, CombiMatrix Corporation has engaged in a continuous process of monitoring and reevaluating the terms of the agreements, and have amended the agreements in several respects to establish more meaningful goals, milestones and timelines. The agreements are non-exclusive with respect to CombiMatrix Corporation's core technology, meaning that CombiMatrix Corporation remains free to license its core technology to third parties for applications in the genomics, proteomics and other fields. The agreements contain exclusivity or co-exclusivity provisions only with respect to the specific products being co-developed for, and partially funded by, Roche pursuant to the agreements. Under the terms of the agreements, it is contemplated that Roche will co-develop, use, manufacture, market and distribute CombiMatrix Corporation's array and related technology for rapid production of customizable arrays. The agreements provide for minimum payments by Roche to CombiMatrix Corporation over the first three years after product launch, including milestone achievements, payments for products, royalties and future research and development projects. Nevertheless, because our agreements with Roche contain provisions that would allow Roche to terminate the agreements, the future payments by Roche to CombiMatrix Corporation might never be realized. Since July 2001, CombiMatrix Corporation has received approximately $26.6 million in cash payments from Roche from July 2001 through December 31, 2003. The CombiMatrix group has not received any additional payments from Roche since December 31, 2003. MANUFACTURING AND CUSTOMIZATION The CombiMatrix group is developing automated, computer-directed manufacturing processes for the synthesis of sequences of DNA, RNA, peptides or small molecules on its arrays. Certain portions of its manufacturing, such as semiconductor fabrication and processing, will be outsourced to subcontractors, while the steps involving synthesis of biological materials and quality control of its products will be conducted by the CombiMatrix group. Substantially all of the components and raw materials used in the manufacture of the CombiMatrix group's products, including semiconductors and reagents, are currently provided from a limited number of sources or in some cases from a single source. Although the CombiMatrix group believes that alternative sources for those components and raw materials are available, any supply interruption in a sole-sourced component or raw material might result in up to a several-month production delay and materially harm the CombiMatrix group's ability to manufacture products until a new source of supply, if any, could be located and qualified. In addition, an uncorrected impurity or supplier's variation in a raw material, either unknown to the CombiMatrix group or incompatible with its manufacturing process, could have a material adverse effect on its ability to manufacture products. The CombiMatrix group may be unable to find a sufficient alternative supply channel in a reasonable time period, or on commercially reasonable terms, if at all. The CombiMatrix group utilizes non-standard semiconductor manufacturing processes to fabricate the electrode array that is a key aspect of the array structure. Although the CombiMatrix group has a supply agreement in place with the semiconductor wafer manufacturer to ensure availability of the raw materials, it does not guarantee a permanent supply. These non-standard processes are not widely available and it may be difficult or expensive to obtain sufficient quantities of semiconductor wafers if the current manufacturer changes or discontinues its manufacturing production capability. PATENTS AND LICENSES CombiMatrix Corporation continues to build its intellectual property portfolio to protect its product in those markets where it operates and where a market for its products and services exists. In the United States, CombiMatrix Corporation has been issued four United States patents. Three of the United States patents (U.S. Patent No. 6,093,302 expiration date January 5, 2018; U.S. Patent No. 6,280,595 expiration date September 10, 2019 and U.S. Patent No. 6,444,111 expiration date October 13, 2019) protect CombiMatrix Corporation's core technology relating to methods for electrochemical synthesis of arrays. The fourth United States Patent (U.S. Patent No. 6,456,942 expiration date January 25, 2020) describes and claims a network infrastructure for custom array synthesis and analysis. Corresponding CombiMatrix Corporation core patents describing and claiming methods for electrochemical synthesis of arrays have been issued in Europe (entire EU), Australia and Taiwan and are pending in the remaining major industrialized markets. In total, CombiMatrix Corporation has 59 patent applications pending in the Unites States, Europe and elsewhere. The CombiMatrix group seeks to protect its corporate identity with trademarks and service marks. In addition, its trademark strategy includes protecting the identity and goodwill associated with its biological array processor products. The CombiMatrix group purchases chemical reagents from suppliers who are licensed under appropriate patent rights. It is the CombiMatrix group's policy to obtain licenses from patent holders if needed to practice its chemical processes. 10 The CombiMatrix group's success will depend, in part, upon its ability to obtain patents and maintain adequate protection of its intellectual property in the United States and other countries. If it does not protect its intellectual property adequately, competitors may be able to use its technologies and thereby erode any competitive advantage that the CombiMatrix group may have. The laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and many companies have encountered significant problems in protecting their proprietary rights abroad. These problems can be caused by the absence of rules and methods for defending intellectual property rights. The patent positions of companies developing tools and drugs for the biotechnology and pharmaceutical industries, including the CombiMatrix group's patent position, generally are uncertain and involve complex legal and factual questions. The CombiMatrix group will be able to protect its proprietary rights from unauthorized use by third parties only to the extent that its proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. The CombiMatrix group's existing patent and any future patents it obtains may not be sufficiently broad to prevent others from practicing its technologies or from developing competing products. There also is risk that others may independently develop similar or alternative technologies or design around its patented technologies. In addition, others may challenge or invalidate the CombiMatrix group's patents, or its patents may fail to provide it with any competitive advantage. Enforcing its intellectual property rights may be difficult, costly and time consuming, and ultimately may not be successful. The CombiMatrix group also relies upon trade secret protection for its confidential and proprietary information. It seeks to protect its proprietary information by entering into confidentiality and invention disclosure and transfer agreements with employees, collaborators and consultants. These measures, however, may not provide adequate protection for the CombiMatrix group's trade secrets or other proprietary information. Employees, collaborators or consultants may still disclose its proprietary information, and the CombiMatrix group may not be able to meaningfully protect its trade secrets. In addition, others may independently develop substantially equivalent proprietary information or techniques or otherwise gain access to its trade secrets. The CombiMatrix group cannot assure you that any of its patent applications will result in the issuance of any additional patents, that its patent applications will have priority of invention or filing date over similar rights of others, or that, if issued, any of its patents will offer protection against its competitors. Additionally, the CombiMatrix group cannot assure you that any patent issued to it will not be challenged, invalidated or circumvented in the future or that the intellectual property rights it has created will provide a competitive advantage. Litigation may be necessary to enforce its intellectual property rights or to determine the enforceability, scope of protection or validity of the intellectual property rights of others. COMPETITION The CombiMatrix group expects to encounter competition in the area of business opportunities from other entities having similar business objectives. Many of these potential competitors possess greater financial, technical, human and other resources than does the CombiMatrix group. The CombiMatrix group anticipates that it will face increased competition in the future as new companies enter the market and advanced technologies become available. In the life sciences industry, many competitors have more experience in research and development than the CombiMatrix group. Technological advances or entirely different approaches developed by one or more of its competitors could render the CombiMatrix group's processes obsolete or uneconomical. The existing approaches of competitors or new approaches or technology developed by competitors may be more effective than those developed by the CombiMatrix group. The CombiMatrix group is aware of other companies or companies with divisions that have, or are developing, technologies for the SNP genotyping, gene expression profiling and proteomic markets. The CombiMatrix group believes that its primary competitors will be Affymetrix, Inc., Agilent Technologies, Inc., Becton, Dickinson and Company, Ciphergen Biosystems, Inc., Gene Logic Inc., Illumina, Inc., Johnson & Johnson, Nanogen, Inc., Orchid Biosciences, Inc., Applera Corporation, Roche Diagnostics GmbH and Sequenom, Inc. However, the CombiMatrix group's market is rapidly changing, and the CombiMatrix group expects to face additional competition from new market entrants, new product developments and consolidation of its existing competitors. Many of the CombiMatrix group's competitors have existing strategic relationships with major pharmaceutical and biotechnology companies, greater commercial experience and substantially greater financial and personnel resources than it does. The CombiMatrix group expects new competitors to emerge and the intensity of competition to increase in the future. RESEARCH, DEVELOPMENT AND ENGINEERING The CombiMatrix group's research and development expenses, excluding non-cash stock compensation charges and acquired in-process research and development charges, were $7.2 million (including Department of Defense related research and development expenses of $2.0 million), $8.1 million and $18.2 million during 2004, 2003 and 2002, respectively. Research and development 11 related non-cash stock compensation charges were $91,000, $466,000 and $1.9 million during 2004, 2003 and 2002, respectively and acquired in-process research and development charges were $17.2 million in 2002. The CombiMatrix group intends to invest in its proprietary technologies through internal development and, to the extent available, licensing of third-party technologies to increase and improve other characteristics of its products. The CombiMatrix group also plans to continue to invest in improving the cost-effectiveness of its products through further automation and improved information technologies. The CombiMatrix group's future research and development efforts may involve research conducted by the CombiMatrix group, collaborations with other researchers and the acquisition of chemistries and other technologies developed by universities and other academic institutions. The CombiMatrix group is developing a variety of life sciences and non-life sciences products and services. Potential customers for these products operate in industries characterized by rapid technological development. The CombiMatrix group believes that its future success will depend in large part on its ability to continue to enhance its existing products and services and to develop other products and services, which complement existing ones. In order to respond to rapidly changing competitive and technological conditions, the CombiMatrix group expects to continue to incur significant research and development expenses during the initial development phase of new products and services, as well as on an ongoing basis. GOVERNMENT GRANTS AND CONTRACTS Government grants and contracts have allowed the CombiMatrix group to fund certain internal scientific programs and exploratory research. The CombiMatrix group retains ownership of all intellectual property and commercial rights generated during these projects. The United States government, however, retains a non-exclusive, non-transferable, paid-up license to practice the inventions made with federal funds pursuant to applicable statutes and regulations. The CombiMatrix group does not believe that the retained license will have any impact on its ability to market its products. The CombiMatrix group does not need government approval to enter into collaborations or other relationships with third parties. The CombiMatrix group has been awarded several grants from the federal government in connection with its biological array processor technology since it's inception. Most recently, in March of 2004, the CombiMatrix group was awarded a two-year, $5.9 million contract with the Department of Defense to further the development of the CombiMatrix group's array technology for the detection of biological threat agents. Under the terms of the contract, the CombiMatrix group will be reimbursed on a periodic basis for actual costs incurred to perform its obligations, plus a fixed fee, of up to $5.9 million. The CombiMatrix group will continue to pursue grants and contracts that complement its research and development efforts. RECENT ACTIVITIES Significant milestones for the CombiMatrix group during 2004 include the following: GENETIC ANALYSIS PRODUCTS AND SERVICES o In March 2004, the CombiMatrix group launched the CustomArray(TM) DNA Microarray platform, its first commercially-available array product, to the worldwide research marketplace. This platform offers researchers the ability to order fully customizable arrays on demand in any quantity they choose. CustomArrays(TM) are produced on a standard slide format, a configuration that is most familiar to researchers. The commercial launch of CustomArray(TM) also provides the marketplace with full access to the CombiMatrix group's suite of software applications, including array design and submission, online ordering and extraction of experimental results. o In June 2004, the CombiMatrix group entered into a co-marketing relationship with Axon Instruments, Inc. and in July, the CombiMatrix group entered into a co-marketing agreement with Strand Genomics. o In July 2004, the CombiMatrix group launched the CustomArray(TM)12K DNA expression array, offering researchers the ability to order a fully customizable array with more than 12,000 sites.

Also in July 2004, the CombiMatrix group made available to researchers new CustomArrays(TM) for Human Drug Metabolism, Human Toxicology, and a Core 67 Cancer Array. o In August 2004, the CombiMatrix group entered into a multi-year collaborative strategic alliance with Furuno Electric Company, Ltd. ("Furuno") to design, engineer and build CombiMatrix Corporation's Bench-Top DNA Microarray Synthesizer for CustomArray(TM) formatted arrays. Under the terms of the agreement, Furuno paid CombiMatrix Corporation an upfront fee of $1,000,000 and will make additional development and milestone payments in the future, in accordance with the agreement. 12 o In December 2004, the CombiMatrix group launched Design-on-Demand(TM) Arrays, which provides the marketplace with a comprehensive catalog of microarray expression products for microbial, eukaryotic, and viral genomes. These arrays offer scientists an affordable and flexible tool to conduct whole-genome expression studies on a wide range of organisms, including Influenza, HIV, Anthrax, and SARS coronavirus. HOMELAND SECURITY AND DEFENSE APPLICATIONS o In March 2004, the CombiMatrix group executed a two-year, $5.9 million contract with the Department of Defense to further the development of the CombiMatrix group's microarray technology for the detection of biological threat agents. Additionally, In July 2004, the CombiMatrix group announced that it will receive an additional $2.3 million from a Department of Defense appropriations bill passed by Congress. o In October 2004, the CombiMatrix group and Science Applications International Corporation (SAIC) announced a collaboration to develop arrays for the identification of multiple bio-threat organisms. The intent of the collaboration is to leverage each company's respective Department of Defense funding in order to expedite the development and testing of new identification and diagnostic assays and products against conventional bio-threat agents and emerging and genetically engineered pathogens. DRUG DISCOVERY o In January 2004, the CombiMatrix group made the first commercially available microarray designed for the H5N1 influenza A virus ("bird flu"). The World Health Organization appealed on January 27, 2004 for technical assistance and expert advice to help stop the threat to humans and agriculture posed by bird flu virus. The CombiMatrix group utilized its proprietary probe-design software and ability to rapidly synthesize novel DNA arrays to respond within two days. o During 2004, the CombiMatrix group entered into a number of collaborations in the field of drug discovery and development, including collaborations with: 1) Washington University in St. Louis to develop a system for the synthesis of libraries of diverse, non-nucleic acid molecules; 2) Professor Bonaventura Clotet, M.D., Ph.D., of the Retrovirology Laboratory irsiCaixa, to conduct the initial efficacy screening of pooled siRNA compounds against the hepatitis C virus; 3) Dr. Ulrich Melcher, Department of Biochemistry and Molecular Biology and Dr. Alexander C. Lai, Department of Microbiology and Molecular Genetics from Oklahoma State University to utilize CombiMatrix group's `Bird Flu' CustomArray(TM) devices to characterize Bird flu viruses at the genomic level; 4) St. Jude Children's Research Hospital to study the genetic variation in the H9 variant of Bird Flu; and 5) Case Western Reserve University for work in developing a novel diagnostic for Alzheimer's disease using the CustomArray(TM) platform. o In October 2004, the CombiMatrix group entered into an agreement to acquire up to a one-third ownership interest in Leuchemix, Inc. ("Leuchemix"), a private drug development firm, which is developing several compounds for the treatment of leukemia and other cancers. In accordance with the terms of the purchase agreement, the CombiMatrix group will purchase 3,137,500 shares of Series A Preferred Stock of Leuchemix for a total purchase price of $4,000,000, to be paid quarterly over the next two years. In accordance with the terms of the purchase agreement, CombiMatrix Corporation's Chief Executive Officer was named a director of Leuchemix. NANOTECHNOLOGY o In January 2004, the CombiMatrix group entered into collaboration with Cyrano Sciences (which has been acquired by Smiths Detection) to develop nanotechnology-based chemical sensors to be used for the detection of biological agents in air and water. o In September 2004, the CombiMatrix group and Intel Corporation entered into an agreement to work together on the feasibility of various projects utilizing the CombiMatrix group's core technology. The terms and conditions of the agreement are confidential. o During 2004, the CombiMatrix group's strategic partner, Nanomaterials Discovery Corporation, was granted a U.S. patent entitled, "Electrode Array for Development and Testing of Materials." In August 2004, Nanomaterials Discovery Corporation received a $2.5 million Department of Defense appropriation for the development of fuel cell technology, which will utilize CombiMatrix group's NanoArray(TM) technology as a 13 component of this development. In December 2004, Nanomaterials Discovery Corporation delivered its first prototype nanomaterials workstation to the CombiMatrix group. ADDITIONS TO THE COMBIMATRIX GROUP'S SCIENTIFIC ADVISORY BOARD o In February 2004, the CombiMatrix group named F. Mark Modzelewski to its Scientific Advisory Board. Mr. Modzelewski is currently a principal of Lux Capital, a New York based venture capital firm, and is also a member of the Nanotechnology Technical Advisory Group to President Bush's Council of Advisors on Science and Technology (PCAST). Mr. Modzelewski was recognized by Forbes magazine as one of nanotech's five "powerbrokers" and he has testified before the U.S. Senate on nanotechnology funding, investment, technology transfer and global competition. o In April 2004, the CombiMatrix group named Mark A. Kay, M.D., Ph.D., to its Scientific Advisory Board. Dr. Kay is a Professor, Departments of Pediatrics and Genetics, and Director, Program in Human Gene Therapy, at the Stanford University School of Medicine. Dr. Kay is one of the founders of and is currently the Vice President of the American Society of Gene Therapy and a leader and pioneer in areas including RNAi, gene and nucleic-acid drug delivery, and gene therapy. EMPLOYEES As of December 31, 2004, the CombiMatrix group had 71 full-time employees, 14 of whom hold Ph.D. degrees and 40 of whom are engaged in full-time research and development activities. The CombiMatrix group is not a party to any collective bargaining agreement. The CombiMatrix group considers its employee relations to be good. ENVIRONMENTAL MATTERS The operations of the CombiMatrix group involve the use, transportation, storage and disposal of hazardous substances, and as a result, it is subject to environmental and health and safety laws and regulations. The cost of complying with these and any future environmental regulations could be substantial. In addition, if the CombiMatrix group fails to comply with environmental laws and regulations, or releases any hazardous substance into the environment, the CombiMatrix group could be exposed to substantial liability in the form of fines, penalties, remediation costs and other damages, or could suffer a curtailment or shut down of its operations. 14 ACACIA TECHNOLOGIES GROUP (A DIVISION OF ACACIA RESEARCH CORPORATION) BUSINESS The Acacia Technologies group, a division of Acacia Research Corporation, including companies recently acquired from Global Patent Holdings as described earlier, is currently comprised of certain of Acacia Research Corporation's wholly owned subsidiaries and limited liability companies including: Acacia Global Acquisition Corporation, Acacia Internet Access Corporation, Acacia Media Technologies Corporation, Acacia Patent Acquisition Corporation, Acacia Technologies Services Corporation, AV Technologies LLC, Broadcast Innovation LLC, Data Innovation LLC, Financial Services Innovation LLC, Information Technology Innovation LLC, InternetAd LLC, IP Innovation LLC, KY Data Systems LLC, New Medium LLC, TechSearch LLC, VData LLC, Soundview Technologies, Inc., and Spreadsheet Automation Corporation and also includes all corporate assets, liabilities, and related transactions of Acacia Research Corporation attributed to the Acacia Research Corporation's intellectual property licensing business.

California 20 THE ACACIA TECHNOLOGIES GROUP'S STRATEGY The Acacia Technologies group's business strategy, conducted solely by our operating subsidiaries, includes the following: IDENTIFY EMERGING GROWTH AREAS WHERE PATENTED TECHNOLOGIES WILL PLAY A VITAL ROLE following key elements:

·    
Identify Emerging Growth Areas where Patented Technologies will Play a Vital Role

The patent process breeds innovation and invention by granting a limited monopoly to the inventor in exchange for sharing the invention with the public. Certain technologies, such asincluding several of the technologies controlled by our DMT technology,operating subsidiaries, some of which are summarized below, become core technologies in the way products and services are manufactured, sold and delivered.  The Acacia Technologies group identifiesOur operating subsidiaries identify core, patented technologies that have been or are anticipated to be widely adopted by third parties in connection with the manufacture or sale of products and services. CONTACT AND FORM ALLIANCES WITH OWNERS OF CORE, PATENTED TECHNOLOGIES For years, many large companies have earned substantial revenue licensing patented technologies to third parties. Other companies that do not have internal licensing resources and expertise have continued to record the estimated value of intellectual property on their financial statements without deriving income from their intellectual property. Recent changes in securities and financial reporting regulations require these companies to evaluate and potentially reduce or write-off these intellectual property assets if they are unable to substantiate these reported values. The

·  Contact and Form Alliances with Owners of Core, Patented Technologies

Often individual inventors and small companies have limited resources and/or expertise and are unable to effectively address the unauthorized use of their patented technologies.  Individual inventors and small companies may lack sufficient capital resources and may also lack in-house personnel with patent licensing expertise and/or experience, which may make it difficult to effectively out-license and/or enforce their patented technologies.

For years, many large companies have earned substantial revenue licensing patented technologies to third parties.  Other companies that do not have internal licensing resources and expertise have continued to record the capitalized carrying value of their intellectual property in their financial statements, without deriving income from their intellectual property or realizing the potential value of their intellectual property assets.  Securities and financial reporting regulations require these companies to periodically evaluate and potentially reduce or write-off these intellectual property assets if they are unable to substantiate these reported carrying values.

Acacia Technologies group seeksResearch Corporation’s subsidiaries seek to enter into business agreements with owners of intellectual property that do not have experience or expertise in the areas of intellectual property licensing and enforcement or that do not possess the in-house resources to devote to licensing and enforcement activities. EFFECTIVELY AND EFFICIENTLY EVALUATE PATENTED TECHNOLOGIES FOR ACQUISITION, LICENSING AND ENFORCEMENT

·  Effectively and Efficiently Evaluate Patented Technologies for Acquisition, Licensing and Enforcement

Subtleties in the language of a patent, recorded interactions with the patent office, and the evaluation of prior art and literature can make a significant difference in the potential licensing and enforcement revenue derived from a patent or patent portfolio.  Our specialists are trained and skilled in these areas.  It is important to identify potential problem areas prior to acquisition and commercialization and determine whether potential problem areas can be overcome, before acquiring a patent portfolio or launching a licensing program.  We have developed processes and procedures for identifying problem areas and evaluating the strength of a patent portfolio before the decision is made to allocate resources to an acquisition or a licensing and enforcement effort.

·  Purchase or Acquire the Rights to Patented Technologies

After evaluation, our operating subsidiaries may elect to purchase the patented technology, or become the exclusive licensing agent for the patented technology in all or in specific fields of use.  In either case, the owner of the patent generally retains the rights to a portion of the net revenues generated from a patent’s licensing and enforcement program.  Our operating subsidiaries generally control the licensing and enforcement process and utilize their experienced in-house personnel to reduce outside costs and to ensure that the necessary capital is allocated and deployed in an efficient and cost effective manner.

·  Successfully License and Enforce Patents with Significant Royalty Potential

As part of the patent evaluation process employed by our operating subsidiaries, significant consideration is also given to the identification of potential infringers, industries within which the potential infringers exist, longevity of the patented technology, and a variety of other factors that directly impact the magnitude and potential success of a licensing and enforcement program.  Our specialists are trained in evaluating potentially infringing technologies and in presenting the claims of our patents and demonstrating how they apply to companies we believe are using our technologies in their products or services.  These presentations generally take place in a non-adversarial business setting, but can also occur through the litigation process, if necessary.

Patent Enforcement Litigation

Our operating subsidiaries are often required to engage in litigation to enforce their patents and patent rights.  Certain of our operating subsidiaries are parties to ongoing patent enforcement related litigation, alleging infringement by third parties of certain of the patented technologies owned or controlled by our operating subsidiaries.
Competition

We expect to encounter increased competition in the area of patent acquisition and enforcement.  This includes an increase in the number of competitors seeking to acquire the same or similar patents and technologies that we may seek to acquire. Companies such as British Technology Group, Rembrandt Management Group, and Intellectual Ventures LLC are already in the business of acquiring the rights to patents for the purpose of licensing and enforcement, and we expect more companies to enter the market.  See, Risk Factors on page 6.
We also compete with venture capital firms and various industry leaders for technology licensing opportunities.  Many of these competitors may have more financial and human resources than our operating subsidiaries.  As we become more successful, we may find more companies entering the market for similar technology opportunities, which may reduce our market share in one or more technology industries that we currently rely upon to generate future revenue.
5

Other companies may develop competing technologies that offer better or less expensive alternatives to our patented technologies that we may acquire and/or out-license.  Many potential competitors may have significantly greater resources than the resources that our operating subsidiaries possess.  Technological advances or entirely different approaches developed by one or more of our competitors could render certain of the technologies owned or controlled by our operating subsidiaries obsolete and/or uneconomical.
Employees
As of December 31, 2007, on a consolidated basis, Acacia Research Corporation had 45 full-time employees.  None of our subsidiaries are a party to any collective bargaining agreement.  We consider our employee relations to be good.

An investment in our stock involves a number of risks.  Before making a decision to purchase our securities, you should carefully consider all of the risks described in this annual report.  If any of the risks discussed in this annual report actually occur, our business, financial condition and results of operations could be materially adversely affected.  If this were to occur, the trading price of our securities could decline significantly and you may lose all or part of your investment.  As used in this Form 10-K, “we,” “us” and “our” refer to Acacia Research Corporation and/or its wholly owned operating subsidiaries.  All intellectual property acquisition, development, licensing and enforcement activities are conducted solely by certain of Acacia Research Corporation’s wholly owned operating subsidiaries.
GENERAL RISKS

WE HAVE A HISTORY OF LOSSES AND WILL PROBABLY INCUR ADDITIONAL LOSSES IN THE FUTURE.
We have sustained substantial losses since our inception resulting in a consolidated net accumulated deficit, as disclosed in the accompanying consolidated financial statements of Acacia Research Corporation included in Part IV Item 15 of this report.  We may never become profitable, or if we do, we may never be able to sustain profitability. We expect to incur significant legal, marketing, general and administrative expenses. As a result, it is more likely than not that we will incur losses for the foreseeable future.
BECAUSE WE HAVE SUSTAINED LOSSES SINCE OUR INCEPTION, WE CANNOT ASSURE THAT OUR OPERATIONS WILL BE PROFITABLE.
We commenced operations in 1993 and, we have sustained substantial losses since our inception resulting in a net consolidated accumulated deficit, as disclosed in the accompanying consolidated financial statements of Acacia Research Corporation included in Part IV Item 15 of this report. If we continue to incur operating losses in future periods, we may not have enough capital to expand our business and our operating subsidiary companies’ businesses in the future.
IF WE, OR OUR SUBSIDIARIES, ENCOUNTER UNFORESEEN DIFFICULTIES AND CANNOT OBTAIN ADDITIONAL FUNDING ON FAVORABLE TERMS, OUR BUSINESS MAY SUFFER.
Acacia Research Corporation's consolidated cash and cash equivalents along with short-term investments totaled $51.4 million and $45.0 million at December 31, 2007 and 2006, respectively.  To date, Acacia Research Corporation has relied primarily upon selling of equity securities and payments from our licensees to generate the funds needed to finance the operations of Acacia Research Corporation and our operating subsidiaries.
We cannot assure you that we will not encounter unforeseen difficulties, including the outside influences identified below, that may deplete our capital resources more rapidly than anticipated. As a result, our subsidiary companies may be required to obtain additional financing through bank borrowings, debt or equity financings or otherwise, which would require us to make additional investments or face a dilution of our equity interests. Any efforts to seek additional funds could be made through equity, debt or other external financings. Nevertheless, we cannot assure that additional funding will be available on favorable terms, if at all. If we fail to obtain additional funding when needed for our subsidiary companies and ourselves, we may not be able to execute our business plans and our business may suffer.
6

FAILURE TO EFFECTIVELY MANAGE OUR GROWTH COULD PLACE STRAINS ON OUR MANAGERIAL, OPERATIONAL AND FINANCIAL RESOURCES AND COULD ADVERSELY AFFECT OUR BUSINESS AND OPERATING RESULTS.
Our growth has placed, and is expected to continue to place, a strain on our managerial, operational and financial resources. Further, as our subsidiary companies’ businesses grow, we will be required to manage multiple relationships. Any further growth by us or our subsidiary companies or an increase in the number of our strategic relationships will increase this strain on our managerial, operational and financial resources. This strain may inhibit our ability to achieve the rapid execution necessary to successfully implement our business plan.
OUR FUTURE SUCCESS DEPENDS ON OUR ABILITY TO EXPAND OUR ORGANIZATION TO MATCH THE GROWTH OF OUR SUBSIDIARIES.
As our subsidiaries grow, the administrative demands upon Acacia Research Corporation and on our operating subsidiaries, will grow, and our success will depend upon our ability to meet those demands. These demands include increased accounting, management, legal services, staff support, and general office services. We may need to hire additional qualified personnel to meet these demands, the cost and quality of which is dependent in part upon market factors outside of our control. Further, we will need to effectively manage the training and growth of our staff to maintain an efficient and effective workforce, and our failure to do so could adversely affect our business and operating results.
THE AVAILABILITY OF SHARES FOR SALE IN THE FUTURE COULD REDUCE THE MARKET PRICE OF OUR COMMON STOCK.
In the future, we may issue securities to raise cash for acquisitions. We may also pay for interests in additional subsidiary companies by using a combination of cash and our common stock or just our common stock. We may also issue securities convertible into our common stock. Any of these events may dilute stockholders ownership interest in our company and have an adverse impact on the price of our common stock.
In addition, sales of a substantial amount of our common stock in the public market, or the perception that these sales may occur, could reduce the market price of our common stock. This could also impair our ability to raise additional capital through the sale of our securities.
DELAWARE LAW AND OUR CHARTER DOCUMENTS CONTAIN PROVISIONS THAT COULD DISCOURAGE OR PREVENT A POTENTIAL TAKEOVER OF ACACIA RESEARCH CORPORATION THAT MIGHT OTHERWISE RESULT IN OUR STOCKHOLDERS RECEIVING A PREMIUM OVER THE MARKET PRICE OF THEIR SHARES.
Provisions of Delaware law and our certificate of incorporation and bylaws could make the following more difficult: the acquisition of our company by means of a tender offer, proxy contest or otherwise, and the removal of incumbent officers and directors. These provisions include:

·   section 203 of the Delaware General Corporation Law, which prohibits a merger with a 15%-or-greater stockholder, such as a party that has completed a successful tender offer, until three years after that party became a 15%-or-greater stockholder;

·   amendment of our bylaws by the stockholders requires a two-thirds approval of the outstanding shares;

·   the authorization in our certificate of incorporation of undesignated preferred stock, which could be issued without stockholder approval in a manner designed to prevent or discourage a takeover;

·   provisions in our bylaws eliminating stockholders’ rights to call a special meeting of stockholders, which could make it more difficult for stockholders to wage a proxy contest for control of our board of directors or to vote to repeal any of the anti-takeover provisions contained in our certificate of incorporation and bylaws; and

·   the division of our board of directors into three classes with staggered terms for each class, which could make it more difficult for an outsider to gain control of our board of directors.
Such potential obstacles to a takeover could adversely affect the ability of our stockholders to receive a premium price for their stock in the event another company wants to acquire us.

AS A RESULT OF THE REDEMPTION OF AR-COMBIMATRIX STOCK FOR THE COMMON STOCK OF COMBIMATRIX CORPORATION, ACACIA RESEARCH CORPORATION MAY BE SUBJECT TO CERTAIN TAX LIABILITY UNDER THE INTERNAL REVENUE CODE.  
Our distribution of the common stock of CombiMatrix Corporation in the redemption will be tax-free to Acacia Research Corporation if the distribution qualifies under Sections 368 and 355 of the Internal Revenue Code.  If the split-off failed to qualify under Section 355 of the Internal Revenue Code, corporate tax would be payable by the consolidated group of which Acacia Research Corporation is the common parent, based upon the difference between the aggregate fair market value of the assets of CombiMatrix Corporation’s business and the adjusted tax bases of such business to Acacia Research Corporation prior to the redemption.
Acacia Research Corporation received a private letter ruling from the IRS to the effect that, among other things, the redemption would be tax free to Acacia Research Corporation and the holders of AR-Acacia Technologies stock and AR-CombiMatrix stock under Sections 368 and 355 of the Internal Revenue Code. The private letter ruling, while generally binding upon the IRS, was based upon factual representations and assumptions and commitments on our behalf with respect to future operations made in the ruling request. The IRS could modify or revoke the private letter ruling retroactively if the factual representations and assumptions in the request were materially incomplete or untrue, the facts upon which the private letter ruling was based were materially different from the facts at the time of the redemption, or if we do not meet certain commitments made.
If the split-off failed to qualify under Section 355 of the Internal Revenue Code, corporate tax, if any, would be payable by the consolidated group of which Acacia Research Corporation is the common parent, as described above.  As such, the corporate level tax would be payable by Acacia Research Corporation. CombiMatrix Corporation has agreed however, to indemnify Acacia Research Corporation for this and certain other tax liabilities if they result from actions taken by CombiMatrix Corporation.  Notwithstanding CombiMatrix Corporation’s agreement to indemnify us, under the Internal Revenue Code’s consolidated return regulations, each member of the Acacia Research Corporation consolidated group, including our company, will be severally liable for these tax liabilities. Further, we may be liable for additional taxes if Acacia Research Corporation takes certain actions within two years following the redemption, as more fully discussed in the immediately following risk factor.  If we are found liable to the IRS for these liabilities, the resulting obligation could materially and adversely affect our financial condition, and we may be unable to recover on the indemnity from CombiMatrix Corporation.
FOLLOWING THE REDEMPTION OF AR-COMBIMATRIX STOCK FOR THE COMMON STOCK OF COMBIMATRIX CORPORATION, ACACIA RESEARCH CORPORATION MAY BE SUBJECT TO CERTAIN TAX LIABILITY UNDER THE INTERNAL REVENUE CODE FOR ACTIONS TAKEN BY EITHER OF THEM FOLLOWING THE REDEMPTION.
Even if the distribution qualifies under Section 368 and 355 of the Internal Revenue Code, it will be taxable to Acacia if Section 355(e) of the Internal Revenue Code applies to the distribution. Section 355(e) will apply if 50% or more of the AR-Acacia Technologies stock or CombiMatrix Corporation’s common stock, by vote or value, is acquired by one or more persons, other than the holders of AR-CombiMatrix stock who receive the common stock of CombiMatrix Corporation in the redemption, acting pursuant to a plan or a series of related transactions that includes the redemption. Any shares of the AR-Acacia Technologies stock, the AR-CombiMatrix stock or the common stock of CombiMatrix Corporation acquired directly or indirectly within two years before or after the redemption generally are presumed to be part of such a plan unless we can rebut that presumption. To prevent applicability of Section 355(e) or to otherwise prevent the distribution from failing to qualify under Section 355 of the Internal Revenue Code, CombiMatrix Corporation has agreed that, until two years after the redemption, it will not take any of the following actions unless prior to taking such action, it has obtained (and provided to us) a written opinion of tax counsel or a ruling from the Internal Revenue Service to the effect that such action will not cause the redemption to be taxable to us (collectively “Disqualifying Actions”):
merge or consolidate with another corporation;
liquidate or partially liquidate;
sell or transfer all or substantially all of its assets;
redeem or repurchase its stock (except in certain limited circumstances); or
take any other action which could reasonably be expected to cause Section 355(e) to apply to the distribution.
8

Further, if Acacia Research Corporation takes any Disqualifying Action, we may be subject to additional tax liability.  Many of our competitors are not subject to similar restrictions and may issue their stock to complete acquisitions, expand their product offerings and speed the development of new technology.  Therefore, these competitors may have a competitive advantage over us.  Substantial uncertainty exists on the scope of Section 355(e), and we may have undertaken, may contemplate undertaking or may otherwise undertake in the future transactions which may cause Section 355(e) to apply to the redemption notwithstanding our desire or intent to avoid application of Section 355(e). Accordingly, we cannot provide you any assurance that we will not be liable for taxes if Section 355(e) applies to the redemption.

BECAUSE OUR BUSINESS OPERATIONS ARE SUBJECT TO MANY UNCONTROLLABLE OUTSIDE INFLUENCES, WE MAY NOT SUCCEED.
Our licensing and enforcement business operations are subject to numerous risks from outside influences, including the following:
·  
New legislation, regulations or rules related to obtaining patents or enforcing patents could significantly increase our operating costs and decrease our revenue.
Our operating subsidiaries acquire patents with enforcement opportunities and are spending a significant amount of resources to enforce those patents. If new legislation, regulations or rules are implemented either by Congress, the United States Patent and Trademark Office, or the courts that impact the patent application process, the patent enforcement process or the rights of patent holders, these changes could negatively affect our expenses and revenue. For example, new rules regarding the burden of proof in patent enforcement actions could significantly increase the cost of our enforcement actions, and new standards or limitations on liability for patent infringement could negatively impact our revenue derived from a patent or patent portfolio. The Acacia Technologies group's specialistssuch enforcement actions. While we are trained and skillednot aware that any such changes are likely to occur in these areas. the foreseeable future, we cannot assure you that such changes will not occur.
·  Trial judges and juries often find it difficult to understand complex patent enforcement litigation, and as a result, we may need to appeal adverse decisions by lower courts in order to successfully enforce our patents.

It is importantdifficult to identify potential problem areas priorpredict the outcome of patent enforcement litigation at the trial level. It is often difficult for juries and trial judges to commercializationunderstand complex, patented technologies, and determinate whether potential problem areas can be overcome, before launchingas a licensing program.result, there is a higher rate of successful appeals in patent enforcement litigation than more standard business litigation. Such appeals are expensive and time consuming, resulting in increased costs and delayed revenue. Although we diligently pursue enforcement litigation, we cannot predict with significant reliability the decisions made by juries and trial courts.
·  More patent applications are filed each year resulting in longer delays in getting patents issued by the United States Patent and Trademark Office.
Certain of our operating subsidiaries hold and continue to acquire pending patents. We have identified a trend of increasing patent applications each year, which we believe is resulting in longer delays in obtaining approval of pending patent applications. The application delays could cause delays in recognizing revenue from these patents and could cause us to miss opportunities to license patents before other competing technologies are developed processesor introduced into the market. See the subheading “Competition is intense in the industries in which our subsidiaries do business and proceduresas a result, we may not be able to grow or maintain our market share for identifying problem areasour technologies and evaluatingpatents,” below.
·  Federal courts are becoming more crowded, and as a result, patent enforcement litigation is taking longer.

Our patent enforcement actions are almost exclusively prosecuted in federal court. Federal trial courts that hear our patent enforcement actions also hear criminal cases. Criminal cases always take priority over our actions. As a result, it is difficult to predict the strengthlength of time it will take to complete an enforcement action. Moreover, we believe there is a trend in increasing numbers of civil lawsuits and criminal proceedings before federal judges, and as a result, we believe that the risk of delays in our patent enforcement actions will have a greater affect on our business in the future unless this trend changes.
·  Any reductions in the funding of the United States Patent and Trademark Office could have an adverse impact on the cost of processing pending patent applications and the value of those pending patent applications.

The assets of our operating subsidiaries consists of patent portfolios, including pending patent applications before the decisionU.S. Patent and Trademark Office (USPTO). The value of our patent portfolios is madedependent upon the issuance of patents in a timely manner, and any reductions in the funding of the USPTO could negatively impact the value of our assets. Further, reductions in funding from Congress could result in higher patent application filing and maintenance fees charged by the USPTO, causing an unexpected increase in our expenses.

·  Competition is intense in the industries in which our subsidiaries do business and as a result, we may not be able to grow or maintain our market share for our technologies and patents.

We expect to allocate resourcesencounter competition in the area of patent acquisition and enforcement as the number of companies entering this market is increasing. This includes competitors seeking to aacquire the same or similar patents and technologies that we may seek to acquire. Companies such as British Technology Group, Rembrandt Management Group, and Intellectual Ventures LLC are already in the business of acquiring the rights to patents for the purpose of licensing and enforcement, effort. PURCHASE OR ACQUIRE THE RIGHTS TO PATENTED TECHNOLOGIES After evaluation,and we expect more companies to enter the Acacia Technologies groupmarket. As new technological advances occur, many of our patented technologies may electbecome obsolete before they are completely monetized. If we are unable to purchasereplace obsolete technologies with more technologically advanced patented technologies, then this obsolescence could have a negative effect on our ability to generate future revenues.

Our licensing business also competes with venture capital firms and various industry leaders for technology licensing opportunities.  Many of these competitors may have more financial and human resources than our company.  As we become more successful, we may find more companies entering the patentedmarket for similar technology opportunities, which may reduce our market share in one or more technology industries that we currently rely upon to generate future revenue.
·  Our patented technologies face uncertain market value.
Our operating subsidiaries have acquired patents and technologies that are at early stages of adoption in the commercial and consumer markets. Demand for some of these technologies is untested and is subject to fluctuation based upon the rate at which our licensees will adopt our patents and technologies in their products and services. Refer to the related risk factor below.
·  As patent enforcement litigation becomes more prevalent, it may become more difficult for us to voluntarily license our patents.
We believe that the more prevalent patent enforcement actions become, the exclusive licensing agentmore difficult it will be for us to voluntarily license our patents. As a result, we may need to increase the patented technology in all or in specific fields of use. In either case, the owner of the patent generally retains the rights to a portion of the revenues generated from a patent's licensing and enforcement program. The Acacia Technologies group generally controls the licensing and enforcement process and utilizes its experienced in-house personnel to reduce outside costs, and ensure that the Acacia Technologies group's capital is allocated and utilized in an efficient and cost effective manner. SUCCESSFULLY LICENSE AND ENFORCE PATENTS WITH SIGNIFICANT ROYALTY POTENTIAL As partnumber of our patent evaluation process, significant consideration is also givenenforcement actions to cause infringing companies to license the identification of potential infringers, industries within whichpatent or pay damages for lost royalties. This may increase the potential infringers exist, longevityrisks associated with an investment in our company.
·  The foregoing outside influences may affect other risk factors described in this annual report.
Any one of the patented technology,foregoing outside influences may cause our company to need additional financing to meet the challenges presented or to compensate for a loss in revenue, and a varietywe may not be able to obtain the needed financing. See the heading “If we, or our subsidiaries, encounter unforeseen difficulties and cannot obtain additional funding on favorable terms, our business may suffer” above.

WE MAY FAIL TO MEET MARKET EXPECTATIONS BECAUSE OF FLUCTUATIONS IN QUARTERLY OPERATING RESULTS, WHICH COULD CAUSE THE PRICE OF ACACIA RESEARCH-ACACIA TECHNOLOGIES COMMON STOCK TO DECLINE.
Our reported revenues and operating results have fluctuated in the past and may continue to fluctuate significantly from quarter to quarter in the future. It is possible that in future periods revenues could fall below the expectations of othersecurities analysts or investors, which could cause the market price of our Acacia Research-Acacia Technologies common stock to decline. The following are among the factors that directly impact the magnitude and potential success of a licensing and enforcement program. could cause our operating results to fluctuate significantly from period to period:
·  the dollar amount of agreements executed each period, which is primarily driven by the nature and characteristics of the technology being licensed and the magnitude of infringement associated with a specific licensee;

·  the specific terms and conditions of agreements executed each period and the periods of infringement contemplated by the respective payments;

·  fluctuations in the total number of agreements executed;

10

·  fluctuations in the sales results or other royalty per unit activities of our licensees that impact the calculation of license fees due;

·  the timing of the receipt of periodic license fee payments and/or reports from licensees;

·  fluctuations in the net number of active licensees period to period;

·  costs related to acquisitions, alliances, licenses and other efforts to expand our operations;

·  the timing of payments under the terms of any customer or license agreements into which our operating subsidiaries may enter; and

·  expenses related to, and the results of, patent filings and other enforcement proceedings relating to intellectual property rights, as more fully described in this section.

OUR REVENUES WILL BE UNPREDICTABLE, AND THIS MAY HARM OUR FINANCIAL CONDITION.

Acacia Technologies group's specialists are trained in evaluating potentially infringing technologies and presenting the application of patents to such technologies. These presentations generally take place in a non-adversarial business setting, but can also occur through the litigation process, if necessary. PATENTS AND LICENSES The Acacia Technologies group owns five issued U.S. patents relating to audio and video transmission and receiving systems, commonly known as audio-on-demand, video-on-demand and audio/video streaming, used for distributing content via various methods as follows: U.S. Patent No. 5,132,992, U.S. Patent No. 5,253,275, U.S. Patent No. 5,550,863, U.S. Patent No. 6,002,720 and U.S. Patent No. 6,144,702. In addition, the Acacia Technologies group owns 31 foreign patents also relating to audio and video transmission and receiving systems technology. Foreign rights include an initial patent granted by the European Patent Office covering Austria, Belgium, Denmark, Finland, France, Germany, Greece, Italy, Luxembourg, Monaco, the Netherlands, Spain, Sweden, 21 Switzerland and the United Kingdom, and patents in Japan, Taiwan and Mexico. In January 2004, the Acacia Technologies group was issued an additional European patent for its DMT Technology. The new patent provides additional coverage in the countries listed above. Acacia Technologies group's U.S. DMT patents expire in 2011 and its foreign DMT patents expire in 2012. In July 2004, the Acacia Technologies group acquired U.S. Patent No. 6,226,677 from LodgeNet Entertainment Corporation. The patent covers technology and methods for redirecting users to a login page when accessing the Internet and expires in 2019. As a result of the January 28, 2005Global Acquisition Corporation's acquisition of the assets of Global Patent Holdings, LLC discussed above, the Acacia Technologies group acquiredin 2005, provided us with ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts, and covercounterparts.  Rights to additional patent portfolios were acquired subsequent to the acquisition of the assets of Global Patent Holdings, bringing the current total number of patent portfolios controlled by Acacia Research Corporation’s operating subsidiaries to approximately 91, covering technologies used in a wide variety of industries.   REGULATORY MATTERSThe acquisitions expand and diversify our revenue generating opportunities. We believe that our cash and cash equivalent balances, anticipated cash flow from operations and other external sources of available credit, will be sufficient to meet our cash requirements through at least March 2009, and for the foreseeable future.  However, due to the nature of our licensing business and uncertainties regarding the amount and timing of the receipt of license fees from potential infringers, stemming primarily from uncertainties regarding the outcome of enforcement actions, rates of adoption of our patented technologies, the growth rates of our existing licensees and other factors, we cannot currently predict the amount and timing of the receipt of license fee revenues with a sufficient degree of precision.

As a result, our revenues may vary significantly from quarter to quarter, which could make our business difficult to manage and cause our quarterly results to be below market expectations. If this happens, the price of our Acacia Research-Acacia Technologies group's DMTcommon stock may decline significantly.

OUR OPERATING SUBSIDIARIES DEPEND UPON RELATIONSHIPS WITH OTHERS TO PROVIDE TECHNOLOGY-BASED OPPORTUNITIES THAT CAN DEVELOP INTO PROFITABLE ROYALTY-BEARING LICENSES, AND IF IT IS UNABLE TO MAINTAIN AND GENERATE NEW RELATIONSHIPS, THEN IT MAY NOT BE ABLE TO SUSTAIN EXISTING LEVELS OF REVENUE OR INCREASE REVENUE.
Our operating subsidiaries do not invent new technologies or products; they depend on acquiring new patents and inventions through their relationships with inventors, universities, research institutions, and others.  If our operating subsidiaries are unable to maintain those relationships and continue to grow new relationships, then they may not be able to identify new technology-based opportunities for growth and sustainable revenue.  Further, because we rely upon acquiring technology is utilizedfrom others, we cannot be certain that we will be able to obtain the volume and quality of available new technologies necessary to sustain our current or future growth.  If we are unable to obtain the necessary volume and quality of new technologies, then we may need to reduce operations or revise our business model.
TECHNOLOGY COMPANY STOCK PRICES ARE ESPECIALLY VOLATILE, AND THIS VOLATILITY MAY DEPRESS THE PRICE OF OUR ACACIA RESEARCH-ACACIA TECHNOLOGIES COMMON STOCK.
The stock market has experienced significant price and volume fluctuations, and the market prices of technology companies have been highly volatile. We believe that various factors may cause the market price of our Acacia Research-Acacia Technologies common stock to fluctuate, perhaps substantially, including, among others, the following:

·  announcements of developments in our patent enforcement actions;

·  developments or disputes concerning our patents;

·  our or our competitors’ technological innovations;

·  developments in relationships with licensees;

11

·  variations in our quarterly operating results;

·  our failure to meet or exceed securities analysts’ expectations of our financial results; or

·  a change in financial estimates or securities analysts’ recommendations;

·  changes in management’s or securities analysts’ estimates of our financial performance;

·  changes in market valuations of similar companies;

·  announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures, capital commitments, new technologies, or patents; and

·  failure to complete significant transactions.
For example, the Nasdaq Computer Index had a range of $1,008.96 - $1,353.94 during the 52-weeks ended December 31, 2007 and the Nasdaq Composite Index had a range of $1,108.49 - $2,892.36 over the same period.  Over the same period, our Acacia Research-Acacia Technologies common stock fluctuated within a range of $8.42 - $17.92, all of which was experienced in the fourth quarter.  We believe fluctuations in our stock price during this period could have been impacted by cable TV, satellite TVcourt rulings in our patent enforcement actions. Court rulings in patent enforcement actions are often difficult to understand, even when favorable or neutral to the value of our patents and telecommunications systems. our overall business, and we believe that investors in the market may overreact, causing fluctuations in our stock prices that may not accurately reflect the impact of court rulings on our business operations and assets.
In the past, companies that have experienced volatility in the market price of their stock have been the objects of securities class action litigation. If our Acacia Research-Acacia Technologies common stock was the object of securities class action litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could materially harm our business and financial results.
THE MARKETS SERVED BY OUR OPERATING SUBSIDIARIES ARE SUBJECT TO RAPID TECHNOLOGICAL CHANGE, AND IF OUR OPERATING SUBSIDIARIES ARE UNABLE TO DEVELOP AND ACQUIRE NEW TECHNOLOGIES AND PATENTS, ITS REVENUES COULD STOP GROWING OR COULD DECLINE.
The cable TV, satellite TVmarkets served by our operating subsidiaries’ licensees frequently undergo transitions in which products rapidly incorporate new features and telecommunications industriesperformance standards on an industry-wide basis. Products for communications applications, high-speed computing applications, as well as other applications covered by our operating subsidiaries’ intellectual property, are based on continually evolving industry standards. Our ability to compete in the future will, however, depend on our ability to identify and ensure compliance with evolving industry standards. This will require our continued efforts and success of acquiring new patent portfolios with licensing and enforcement opportunities. However, we expect to have sufficient liquidity and capital resources for the foreseeable future in order to maintain the level of acquisitions we believe we need to keep pace with these technological advances. However, outside influences may cause the need for greater liquidity and capital resources than expected, as described under the caption “Because our business operations are subject to federal regulation, including FCCmany uncontrollable outside influences, we may not succeed” above.
THE SUCCESS OF OUR OPERATING SUBSIDIARIES DEPENDS IN PART UPON THEIR ABILITY TO RETAIN THE BEST LEGAL COUNSEL TO REPRESENT THEM IN PATENT ENFORCEMENT LITIGATION.
The success of our licensing business depends upon our operating subsidiaries’ ability to retain the best legal counsel to prosecute patent infringement litigation. As our operating subsidiaries’ patent enforcement actions increase, it will become more difficult to find the best legal counsel to handle all of our cases because many of the best law firms may have a conflict of interest that prevents its representation of our subsidiary companies.

OUR OPERATING SUBSIDIARIES, IN CERTAIN CIRCUMSTANCES, RELY ON REPRESENTATIONS, WARRANTIES AND OPINIONS MADE BY THIRD PARTIES, THAT IF DETERMINED TO BE FALSE OR INACCURATE, MAY EXPOSE CERTAIN OF OUR OPERATING SUBSIDIARIES TO CERTAIN LIABILITIES THAT COULD BE MATERIAL.
From time to time, our operating subsidiaries may rely upon representations and warranties made by third parties from whom certain of our operating subsidiaries acquired patents or the exclusive rights to license and enforce patents. We also may rely upon the opinions of purported experts.  In certain instances, we may not have the opportunity to independently investigate and verify the facts upon which such representations, warranties, and opinions are made. By relying on these representations, warranties and opinions, our operating subsidiaries may be exposed to liabilities in connection with the licensing and other requirements. These industries are also often subjectenforcement of certain patents and patent rights.  It is difficult to extensive regulation bypredict the extent and nature of such liabilities which, in some instances, may be material.

12

IN CONNECTION WITH PATENT ENFORCEMENT ACTIONS CONDUCTED BY CERTAIN OF OUR SUBSIDIARIES, A COURT MAY RULE THAT OUR SUBSIDIARIES HAVE VIOLATED CERTAIN STATUTORY, REGULATORY, FEDERAL, LOCAL OR GOVERNING RULES OR STANDARDS, WHICH MAY EXPOSE US AND OUR OPERATING SUBSIDIARIES TO MATERIAL LIABILITIES, WHICH COULD MATERIALLY HARM OUR OPERATING RESULTS AND OUR FINANCIAL POSITION.
In connection with any of our patent enforcement actions, it is possible that a defendant may request and/or a court may rule that we have violated statutory authority, regulatory authority, federal rules, local and state authorities. While most cable TV, satellite TV and telecommunication industry regulations do not apply directlycourt rules, or governing standards relating to the Acacia Technologies group, they affect programming distributors,substantive or procedural aspects of such enforcement actions.  In such event, a court may issue monetary sanctions against us or our operating subsidiaries or award attorney’s fees and/or expenses to a defendant(s), which could be material, and if required to be paid by us or our operating subsidiaries, could materially harm our operating results and our financial position.

OUR INVESTMENTS IN AUCTION RATE SECURITIES ARE SUBJECT TO RISKS, INCLUDING THE CONTINUED FAILURE OF FUTURE AUCTIONS, WHICH MAY CAUSE US TO INCUR LOSSES OR HAVE REDUCED LIQUIDITY.
We invest our cash balances in high-quality issuers and limit the amount of credit exposure to any one issuer other than the United States government and its agencies. At December 31, 2007, our investments in marketable securities consist of United States Government and Government Agency Bonds, and auction rate securities. Our auction rate securities are investment grade quality and are in compliance with our investment policy as of the large potential customers forend of 2007. We believe that the technologies coveredfair value of these investments continue to approximate their par value; however, we did experience failed auctions with certain of our issues in February 2008.  Given the deteriorating credit markets, and the increased incidence of failure within the auction market in February 2008, there can be no assurance as to when we would be able to liquidate a particular issue. In such case of a failure, the auction rate securities continue to pay interest in accordance with their terms; however, we may not be able to access the par value of the invested funds until a future auction of these investments is successful, the security is called by the Acacia Technologies group patent portfolio. The Acacia Technologies group monitors pending legislation and administrative proceedingsissuer or a buyer is found outside of the auction process.  Furthermore, if this situation were to ascertain relevance, analyze impact and develop strategies regarding regulatory trends and developments within these industries. Federal law requires cable TV operatorspersist despite our ability to reserve up to one-third of a system's channel capacity for local commercial television stations that have elected must-carry status. In addition, a cable TV system is generallyhold such investments until maturity, we may be required to carry local non-commercial television stations. The FCC has also implemented comparable rules for satellite TV carriers requiring that if a satellite TV system carries one local broadcast stationrecord an impairment charge in a local market pursuantfuture period.  The systemic failure of future auctions for auction rate securities may result in a loss of liquidity, substantial impairment to our investments, realization of substantial future losses, or a royalty-free license granted undercomplete loss of the Satellite Home Viewer Improvement Act of 1999, then it must carry all local broadcast stations in that market. To meet these requirements, some cable TV and satellite TV systems must decide which programming services to keep and which to remove in order to make space available for local television stations. These must-carry requirements may impact the Acacia Technologies group's information-on-demand and streaming media business by causing cable TV and satellite TV systems operators to reduce the number of channels on their systems that would have used technologies covered by Acacia Technologies group's patent portfolio. COMPETITION The Acacia Technologies group expects to encounter competitioninvestment in the arealong-term which may have a material adverse effect on our business, results of business opportunities from other entities having similar business objectives.

Item 6.            SELECTED FINANCIAL DATA
The consolidatingconsolidated selected balance sheet data as of December 31, 20042007 and 20032006 and the consolidatingconsolidated selected statementstatements of operations data for the years ended December 31, 2004, 20032007, 2006 and 20022005 set forth below have been derived from our audited consolidated financial statements included elsewhere herein, and should be read in conjunction with those financial statements (including notes thereto).  The consolidatingconsolidated selected balance sheet data as of December 31, 2002, 20012005, 2004 and 20002003 and the consolidatingconsolidated selected statementstatements of operations data for the years ended December 31, 20012004 and 20002003 have been derived from auditedunaudited consolidated financial statements not included herein, but which were previously filed with the SEC. Acacia Research Corporation derived the Acacia Technologies group and CombiMatrix group balance sheet data and statement of operations data from the separate audited financial statements of the Acacia Technologies group and the CombiMatrix group for the years ended December 31, 2004, 2003 and 2002 included elsewhere herein, and the table should be read in conjunction with those financial statements and related notes. The AR-Acacia Technologies stock and the AR-CombiMatrix stock are intended to reflect the separate performance of the respective divisions of Acacia Research Corporation, rather than the performance of Acacia Research Corporation as a whole. The chief mechanisms intended to cause the AR-Acacia Technologies stock and the AR-CombiMatrix stock to reflect the financial performance of the respective groups are provisions in our restated certificate of incorporation and common stock policies governing dividends and distributions to each class of stock, which specifically require the allocation of earnings to each class based upon the performance of the two groups determined in accordance with generally accepted accounting principles. Under these provisions, Acacia Research Corporation factors the assets and liabilities and income or losses attributable to the respective groups, determined as described under Item 7 "Management's Discussion and Analysis of Financial Condition and Results

Consolidating Statements of Operations - Critical Accounting Policies," into the determination of the amounts available to pay dividends, if any, on the shares issued for the respective groups and require Acacia Research Corporation to exchange, redeem or distribute a dividend on the stock of a group if all or substantially all of the assets allocated to the respective group are sold to a third party. The Acacia Technologies group and the CombiMatrix group are not separate legal entities. Holders of AR-Acacia Technologies stock and AR-CombiMatrix stock are stockholders of Acacia Research Corporation. As a result, stockholders continue to be subject to all of the risks of an investment in Acacia Research Corporation and all of its businesses, assets and liabilities. The assets that Acacia Research Corporation attributes to one group could be subject to the liabilities of the other group. 26 CONSOLIDATING STATEMENT OF OPERATIONS DATA(4) (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA) FOR THE YEARS ENDED DECEMBER 31, --------------------------------------------------------------------------- 2004 2003 2002 2001 2000 ------------ ------------ ------------ ------------ ------------ REVENUES: Acacia Technologies group ........................ $ 4,284 $ 692 $ 43 $ 24,180 $ 40 CombiMatrix group ................................ 19,641 456 839 456 17 ------------ ------------ ------------ ------------ ------------ ACACIA RESEARCH CORPORATION ...................... $ 23,925 $ 1,148 $ 882 $ 24,636 $ 57 ============ ============ ============ ============ ============ OPERATING (LOSS) INCOME Acacia Technologies group ........................ $ (6,055) $ (6,013) $ (9,865) $ 5,858 $ (12,606) CombiMatrix group ................................ 261 (19,349) (70,460) (49,056) (24,557) ------------ ------------ ------------ ------------ ------------ ACACIA RESEARCH CORPORATION ...................... $ (5,794) $ (25,362) $ (80,325) $ (43,198) $ (37,163) ============ ============ ============ ============ ============ OTHER (EXPENSE) INCOME, NET: Acacia Technologies group ........................ $ 471 $ 408 $ (3,503) $ 2,111 $ (2,897) CombiMatrix group ................................ 313 214 392 2,055 1,662 ------------ ------------ ------------ ------------ ------------ ACACIA RESEARCH CORPORATION ...................... $ 784 $ 622 $ (3,111) $ 4,166 $ (1,235) ============ ============ ============ ============ ============ (LOSS) INCOME FROM CONTINUING OPERATIONS BEFORE MINORITY INTERESTS: Acacia Technologies group ........................ $ (5,445) $ (5,468) $ (12,658) $ 7,034 $ (15,509) CombiMatrix group ................................ 710 (18,999) (69,921) (46,846) (22,816) ------------ ------------ ------------ ------------ ------------ ACACIA RESEARCH CORPORATION ...................... $ (4,735) $ (24,467) $ (82,579) $ (39,812) $ (38,325) ============ ============ ============ ============ ============ MINORITY INTERESTS: Acacia Technologies group ........................ $ 6 $ 17 $ 104 $ (1,277) $ 866 CombiMatrix group ................................ -

- ------------------- (1) On February 13, 2001, the board of directors of Soundbreak.com, one of our majority-owned subsidiaries, resolved to cease operations as of February 15, 2001 and liquidate the remaining assets and liabilities of Soundbreak.com. See Note 11 to the Acacia Research Corporation consolidated financial statements. (2) Certain potential common shares for the periods shown above have been excluded from the per share calculations because the effect of their inclusion would be anti-dilutive. Data
(In addition, allthousands, except share and per share information has been adjusted as appropriate for all periods presented to reflect a ten percent (10%) stock dividend distributed on December 5, 2001 for stockholders of record as of November 21, 2001. (3) Effective January 1, 2001, we changed our accounting policy for balance sheet classification of employee stock-based compensation resulting from awards in consolidated subsidiaries. As a result, effective January 1, 2001, amortized non-cash stock compensation charges related to subsidiary stock options are included in minority interests in our consolidated balance sheet. Prior to the change in accounting policy, amortized non-cash stock compensation charges related to subsidiary stock options were reflected as "accrued stock compensation" in consolidated liabilities. There is no impact on previous consolidated statements of operations as a result of this change in accounting policy. Total liabilities at December 31, 2001 include a capital lease obligation totaling $2.8 million which was paid in full in October 2002. (4)data)

The CombiMatrix group and thebusiness conducted by Acacia Technologies group's businesses areResearch Corporation’s operating subsidiaries, is described more fully in Item 1. "Business,"“Business,” of this report. OVERVIEW COMBIMATRIX GROUP During 2004, the CombiMatrix group's

Overview

Our operating activities were highlighted by the completion of its researchduring 2007, 2006 and development agreement with Roche, the execution of a two-year, $5.9 million contract with the Department of Defense to further the development of the CombiMatrix group's microarray technology for the detection of biological threat agents, execution of a multi-year collaboration agreement with Furuno Electric Co. to develop a bench-top DNA array synthesizer and the launch of CustomArray(TM), its first commercially available array platform. The CombiMatrix group also continued its efforts in the area of drug discovery by executing a research and development agreement in the area of siRNA with irsiCiaxa Foundation and by making a minority investment in Leuchemix, which is developing potential therapies to treat leukemia. As a result of completing its research and development agreement with Roche, the CombiMatrix group's research and development programs shifted to a number of internally funded programs that support the activities summarized above. With the completion of its obligations under the Roche agreements, research and development expenses continued to decrease in 2004, as compared to 2003, as efforts shifted to internally funded research and development programs. The decrease in research and development expenses was partially offset by an increase in marketing and sales expenses related to the launch of the CombiMatrix group's CustomArray(TM) 902 DNA array platform in March 2004 and its CustomArray(TM) 12K DNA expression array in July 2004. Historically, the CombiMatrix group was substantially dependent on its research and development arrangements with Roche, relying on payments by Roche to fund the majority of its research and development activities and related resources engaged in fulfilling its contractual obligations to Roche. Roche's primary service to the CombiMatrix group is to distribute its technology platform. If the CombiMatrix group were to lose its relationship with Roche, the CombiMatrix group would continue to distribute its technology platform itself or be required to establish a distribution agreement with other partners. This could prove difficult, time-consuming and expensive, and the CombiMatrix group may not be successful in achieving this objective. During 2003, the CombiMatrix group's operating activities were highlighted by the receipt of significant payments from its strategic partners and licensees, including $9.8 million related to the completion of certain milestones and delivery of prototype products and services pursuant to its agreements with Roche and an up-front payment and a milestone payment totaling $2.4 million pursuant to its agreement with Toppan. The CombiMatrix group also completed several Roche related research and development projects during the third and fourth quarters of 2003, resulting in a decrease in related research and development expenses during 2003, as compared to 2002. The CombiMatrix group continued its efforts with its existing partners and continued to focus on identifying new strategic relationships with the goal of maximizing the opportunities in the life sciences sector that will be created by commercializing its array system. In 2002, the CombiMatrix's group's operating activities were highlighted by the receipt of $11.5 million in milestone payments pursuant to its license, research and development agreements with Roche, which were recorded as deferred revenues. In addition, the CombiMatrix group recognized $533,000 in grant and contract revenues, including $274,000 in grant revenue resulting from completion of its Phase II SBIR Department of Defense contract, $141,000 in one-time contract research and development revenues, $100,000 in revenue related to performance and completion of its Phase I National Institutes of Health grant and $306,000 from the sale of a genomics array synthesizer system and related array products to two institutions in Japan. 30 ACACIA TECHNOLOGIES GROUP In 2004 and 2003, the Acacia Technologies group's operating activities2005, were principally focused on the continued development, licensing and commercializationenforcement of its DMTthe patent portfolio.portfolios owned or controlled by our operating subsidiaries, including the continued pursuit of multiple ongoing technology licensing and enforcement  programs and the commencement of new technology licensing and enforcement programs.  In addition, we continued our focus on business development, including the acquisition of several additional patent portfolios by certain of our operating subsidiaries and the continued pursuit of additional opportunities to partner with patent owners and provide our unique intellectual property licensing, development and enforcement services.

License fee revenues recognized in 2007 totaled $52.6 million, representing a 51% increase over revenues recognized in 2006, which totaled $34.8 million, and a greater than 100% increase over revenues recognized in 2005, which totaled $19.6 million.  The Acacia Technologies group began to recognize DMTincrease in license fee revenues in 20032007 and continued its focus on commercializing its DMT2006 reflects the impact of the increase in patent portfolios owned or controlled by our operating subsidiaries, and the increase in the number of patent licensing and enforcement programs launched and generating revenues since the end of 2005.

Revenues for 2007 included license fees from 91 new licensing agreements covering 16 of our technology licensing and enforcement programs, as compared to 72 new licensing agreements covering 14 of our technology licensing and enforcement programs in 2006 and 83 new licensing agreements covering 12 of our technology licensing and enforcement programs in 2005.  On a consolidated basis, our operating subsidiaries generated licensing revenues from 8 new technology licensing and enforcement programs during 2004.2007, as compared to 7 new programs in 2006 and 11 new programs in 2005.  To date, on a consolidated basis, we have generated revenues from 28 technology licensing and enforcement programs.

License fee revenues for 2007 included fees from the Acacia Technologies group has entered into 294 DMT licensing agreements, including 107 cable TV licenses, 182 licensesof our Color Correction for online entertainment, movies, news, sports, e-learningVideo Graphics Systems technology, DMT® technology, Audio/Video Enhancement and corporate websitesSynchronization technology, Audio Communications Fraud Detection technology, Credit Card Fraud Protection technology, Electronic Address List Management technology, Image Resolution Enhancement technology, Pop-Up Internet Advertising technology, Portable Storage Devices with Links technology, Multi-dimensional Bar Codes technology, Product Activation technology, Rule Based Monitoring technology, Spreadsheet Automation technology, Telematics technology, Vehicle Magnetic Braking technology and licenses with 5 companies that provide over 90%Virtual Computer Workspaces technology licensing programs.

Management measures and assesses the performance and growth of video-on-demand TV entertainment to the hotel industry in the United States. During 2004, we executed 170 DMT license agreements. In the first, second, thirdpatent licensing and fourth quarters of 2004, the Acacia Technologies group recorded DMTenforcement business conducted by our operating subsidiaries based on consolidated license fee revenues recognized across all of $599,000, $666,000, $740,000our technology licensing and $779,000, respectively, compared to $6,000, $19,000, $186,000 and $481,000, respectively, in the comparable 2003 periods. The Acacia Technologies group's continued development, and commercializationenforcement programs on a trailing twelve-month basis.  Trailing twelve-month revenues totaled $52.6 million as of the DMT patent portfolio included increased marketing, general and administrative expenses in 2004,December 31, 2007, as compared to 2003$47.9 million as of September 30, 2007, $46.8 million as of June 30, 2007, $55.3 million as of March 31, 2007, $34.8 million as of December 31, 2006 and 2002, related$19.6 million as of December 31, 2005.

Operating expenses increased during 2007 and 2006, as compared to 2005, due primarily to the hiring of additional patent licensing, and business development and engineering personnel, and an increase in patent related legal, research and consulting and marketing expenses. Patent related legal expenses excluding V-chip related legal fees, also increased due to an increase in costs incurred in connection with the Acacia Technologies group's ongoing DMT patent commercializationcontinued growth and expansion of our technology licensing and enforcement programs, including increased legal costs related to new patent claimsbusiness and the identification of additional potential licensees of our DMT technologyan increase in corporate, general and increased patent enforcementadministrative costs related to ongoing DMToperations.  Inventor royalties expenses and contingent legal fees expenses increased in 2007 and 2006, as compared to 2005, primarily due to the related increase in license fee revenues, as discussed above, and the impact of the varying economic terms related to inventor agreements and contingent legal fee arrangements associated with the revenue generating patent related litigation as summarizedportfolios in Item 1. "Business," elsewhere herein. In 2004, the Acacia Technologies group alsoeach period.

During 2007, certain of our operating subsidiaries continued to execute itsour business strategy in the area of patent portfolio acquisitions. In July 2004,acquisitions, including, in the Acacia Technologies groupfourth quarter of 2007, the acquisition of, or the acquisition of the rights to, patent portfolios in the Authorized Spending Accounts, Compiler, Copy Protection, Projector, and Virtual Server technology areas.  During 2007, we acquired U.S. Patent No. 6,226,677 from LodgeNet Entertainment Corporation. Thea total of 31 new patent coversportfolios with applications over a wide range of technology areas, as compared to 20 new patent portfolios in 2006 and methods for redirecting users to a login page when accessing the Internet. The8 new patent purchase agreement with LodgeNet Entertainment Corporation includes terms by which the companies will divide any future revenues received by the Acacia Technologies group from licensing the patent. In December 2004, the Acacia Technologies group executed a binding letter of intentportfolios in 2005 (excluding portfolios acquired in connection with the 2005 GPH Acquisition).

In January 2005, acquisitionAcacia Global Acquisition Corporation acquired substantially all of the assets of Global Patent Holdings, as discussed earlier. TheLLC, a privately held patent holding company, which owned 11 patent licensing companies (“GPH Acquisition”).  In connection with the acquisition gives the Acacia Technologies groupwe acquired ownership of companies that own or control the rights to 27 patent portfolios, which includeincluded 120 U.S. patents and certain foreign counterparts, and covercovering technologies used in a wide variety of industries as discussed earlier. Theseindustries.

Refer to “Liquidity and Capital Resources” below for information regarding the impact of patent and patent rights acquisitions expand and diversify theon Acacia Technologies group's revenue generating opportunities and accelerate the execution of the Acacia Technologies group's business strategy of acquiring, developing and licensing patented technologies. As a result of the August 2004 final ruling of non-infringement in the Acacia Technologies group's V-chip litigation, operating results in 2004 include $1.5 million of previously deferred V-chip license fee revenues, $668,000 of previously deferred V-chip related legal costs and an impairment charge of $1.6 million associated with the write-off of 100% of V-chip related goodwill. As a result of the final ruling, the Acacia Technologies group concluded its V-chip licensing program and does not expect to recognize any additional V-chip technology related revenues in future periods. During 2002, the Acacia Technologies group's operating activities were highlighted by the continued building of its executive management team, including the hiring of key media technology and intellectual property industry experts that are responsible for the development, licensing and protection of the Acacia Technologies group's intellectual property and proprietary technologies, as well as the pursuit of additional licensing and strategic business alliances with leading companies in the intellectual property licensing industry. In addition, in 2002, the Acacia Technologies group increased legal and third-party consulting activities related to its ongoing DMT patent marketing and commercialization efforts, including patent claims construction, patent prosecution and related research and engineering costs. CRITICAL ACCOUNTING POLICIES OurResearch Corporation’s consolidated financial statements andfor the separate groupperiods presented.

As of December 31, 2007, we had several option agreements with third-party patent portfolio owners regarding the potential acquisition of additional patent portfolios.
Critical Accounting Policies

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America.  In preparing these financial statements, we make assumptions, judgments and estimates that can have a significant impact on amounts reported in our financial statements. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a regular basis we evaluate our assumptions, judgments and estimates and make changes accordingly.

We believe that, of the significant accounting policies discussed in Note 2 to our consolidated and separate group financial statements, the following accounting policies require our most difficult, subjective or complex judgments: o revenue recognition; o research and development expenses; o accounting for income taxes; o valuation of long-lived and intangible assets and goodwill; o accounting for business combinations, and; o management and allocation policies relating to AR-Acacia Technologies stock and AR-CombiMatrix stock.

·  revenue recognition;
·  stock-based compensation expense;
·  valuation of long-lived and intangible assets; and
·  impairment of marketable securities;

We discuss below the critical accounting assumptions, judgments and estimates associated with these policies. Historically, our assumptions, judgments and estimates relative to our critical accounting policies have not differed materially from actual results. For further information on our critical accounting policies, seerefer to Note 2 to the consolidated financial statements and separate group statements included herein. REVENUE RECOGNITION

20

Revenue Recognition
As described below, significant management judgments must be made and used in connection with the revenue recognized in any accounting period.  Material differences may result in the amount and timing of revenue recognized or deferred for any period, if management made different judgments.

Revenue is recognized, in accordance with Staff Accounting Bulletin No. 104, “Revenue Recognition,” (“SAB No. 104”), when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been performed pursuant to the terms of the agreement, (iii) amounts are fixed or determinable and (iv) collectibility of amounts is reasonably assured. 31 ACACIA TECHNOLOGIES GROUP

We make estimates and judgments when determining whether the collectibility of license fees receivable from licensees is reasonably assured. The Acacia Technologies group assessesWe assess the collectibility of accrued license fees receivable based on a number of factors, including past transaction history with licensees and the credit-worthiness of licensees.  If it is determined that collection is not reasonably assured, the fee is recognized when collectibility becomes reasonably assured, assuming all other revenue recognition criteria have been met, which is generally upon receipt of cash. Management estimates regarding collectibility impact the actual revenues recognized each period and the timing of the recognition of revenues.  Our assumptions and judgments regarding future collectibility could differ from actual events, thus materially impacting our financial position and results of operations. The Acacia Technologies group recognizes

Certain license agreements provide for the payment of contractually determined paid-up license fees to our operating subsidiaries in consideration for the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by our operating subsidiaries.  Generally, the execution of these license agreements also provide for the release of the licensee from certain claims and the dismissal of any pending litigation.  Pursuant to the terms of these agreements, our operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future license and related releases, including no express or implied obligation on our operating subsidiaries’ part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the license and releases upon execution of the agreement.  As such, the earnings process is generally complete upon the execution of the agreement, and revenue is recognized upon execution of the agreement, when collectibility is reasonably assured, and all other revenue recognition criteria have been met.

For those arrangements where royalties cannot be reasonably estimated, our operating subsidiaries recognize revenue upon the receipt of cash or license fee statements from their licensees, as described at Note 2 to our consolidated financial statements contained elsewhere herein.  Our operating subsidiaries recognize certain license fee revenues when earned over the term of the license agreement in exchange for the grant of non-exclusive licenses to use certain technologies for which weour operating subsidiaries own or control patents. WeOur operating subsidiaries recognize revenue for estimates of license fees earned during the applicable period, based on historical activities of licensees, historical sales or per unit growth rates of licensees and other relevant available information regarding licensee activities that factor into the calculation of periodic license fees due.  Revisions, if any, are made for actual licensee fees received in the following quarter. Historically, these revisions have not been material to our consolidated financial statements. For those arrangements where royalties cannot be reasonably estimated, we recognize revenue upon the receipt of cash or license fee statements from our licensees as described at Note 2 to our consolidated financial statements contained elsewhere herein. Our estimatesEstimates of periodic license fees due could differ from actual events, thus materially impacting our financial position and results of operations. The Acacia Technologies group is

COMBIMATRIX GROUP Significant estimates, judgments

Stock-based Compensation Expense
Effective January 1, 2006, Acacia Research Corporation adopted the provisions of Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123R”), which is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation.”  SFAS No. 123R supersedes Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees, and assumptions are requiredamends SFAS No. 95, “Statement of Cash Flows.”  SFAS No. 123R sets forth the accounting requirements for “share-based” compensation payments to employees and non-employee directors and requires all share based-payments to be recognized as expense in connection with the CombiMatrix group's accounting for multiple-element arrangements with strategic partners and licensees. The CombiMatrix group accounts for revenues under multiple-element arrangements in accordance withstatement of operations. In March 2005, the SEC published Staff Accounting Bulletin No. 104, "Revenue Recognition," or 107 (“SAB No. 104107”), which requires stock-based compensation to be classified in the same expense line items as cash compensation (i.e. marketing, general and Emerging Issues Task Force Consensus, or EITF, Issue 00-21, "Revenue Arrangements with Multiple Deliverables," and related pronouncements. Arrangements with multiple elements or deliverables must be segmented into individual units of accountingadministrative expenses).  The compensation cost for all stock-based awards is measured at the grant date, based on the separate deliverables only if there is objective and verifiable evidence of fair value to allocate the consideration received to the deliverables. Accordingly, revenues from multiple-element arrangements involving license fees, up-front payments and milestone payments, which are received and/or billable in connection with other rights and services that represent continuing obligations of the CombiMatrix group, are deferred until all of the multiple elements have been delivered or until objective and verifiable evidence of the fair value of the undelivered elements has been established. Upon establishing objectiveaward (determined using a Black-Scholes option pricing model), and verifiable evidenceis recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).  Determining the fair value of stock-based awards at the elements in multiple-element arrangements, the fair value is allocated to each element of the arrangement, such as license fees or research and development projects, based on the relative fair values of the elements. The CombiMatrix group determines the fair value of each element in multiple-element arrangements based on objective and verifiable evidence of fair value, which is determined for each element based on the price charged when the same element is sold separately to a third party. If objective and verifiable evidence of fair value of all undelivered elements exists but objective and verifiable evidence of fair value does not exist for one or more delivered elements, then revenue is recognized using the residual method. Under the residual method, the revenues from delivered elements are not recognized until the fair value of the undelivered element(s) have been determined. In March 2004, the CombiMatrix group completed all phases of its research and development agreement with Roche. As a result of completing all obligations under this agreement and in accordance with the CombiMatrix group's revenue recognition policies for multiple-element arrangements, the CombiMatrix group recognized all previously deferred Roche related contract revenues during the first quarter of 2004. All payments received togrant date from Furuno and Toppan, totaling $3.4 million, have been classified as deferred revenues in the CombiMatrix group's consolidated balance sheets due to the determination that objective and verifiable evidence of fair value does not currently exist for the remaining undelivered elements. Pursuant to EITF 00-21, SAB No. 104 and related guidance, the elements associated with the amounts received to date and additional milestone payments will be treated as one accounting unit. The up-front fees and cash payments received upon the accomplishment of the contractual milestones will be deferred. Revenue will be recognized when all of the related elements, for which objective and reliable evidence does not exist, have been delivered and there is objective and reliable evidence to support the fair value for all of the undelivered elements. 32 RESEARCH AND DEVELOPMENT EXPENSES The CombiMatrix group accounts for research and development expenses pursuant to Statement of Financial Accounting Standards, or SFAS, No. 2, "Accounting for Research and Development Costs," which requires that all research and development costs be charged to expense as incurred, including costs incurred to acquire technologies, which are utilized in research and development and which have no alternative future use. Also, costs related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. Research and development refers to a plan or design for a new product or process or for a significant improvement to an existing product or process whether intended for sale or use. Significant management estimates and judgments, are required with respect toincluding estimating the determinationmarket price volatility of which costs relate to plans or designs for a new product or process or for a significant improvement to an existing product. Had the CombiMatrix group determined that certain costs incurred were not related to researchour classes of common stock and development activities, different accounting treatment for such costs may have been required. The costs of software developed or obtained for internal use is expensed as incurred until certain capitalization criteria have been met, at which time such costs are capitalized and reported as a component of property and equipment. To date, these costs have been classified as research and development expenses. Significant management estimates are required with respect to the determination of when certain capitalization criteria have been met. Typically this occurs upon completion of a prototype and design phase and a functioning model exists. Thereafter, all software program costs are requiredemployee stock option exercise behavior.

SFAS No. 123R also requires stock-based compensation expense to be capitalized and amortized over the remainingrecorded only for those awards expected to vest using an estimated useful life of the software. Had management made differing judgments regarding the capitalization criteria, different accounting treatment of costs of software developed for internal use may have been required. ACCOUNTING FOR INCOME TAXESpre-vesting forfeiture rate.  As part of the process of preparing our consolidated financial statements, we are requiredsuch, SFAS No. 123R requires Acacia Research Corporation to estimate pre-vesting option forfeitures at the time of grant and reflect the impact of estimated pre-vesting option forfeitures on compensation expense recognized.  Estimates of pre-vesting forfeitures must be periodically revised in subsequent periods if actual forfeitures differ from those estimates.  We consider several factors in connection with our income taxes in eachestimate of the jurisdictions in which we operate. This process involves the estimatingpre-vesting forfeitures including types of our actual current tax exposure together with assessing temporary differences resulting from differing treatmentawards, employee class, and historical pre-vesting forfeiture data.  The estimation of items, such as deferred revenue, amortization of intangibles and asset depreciation for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihoodstock awards that our deferred tax assets will be recovered from future taxable incomeultimately vest requires judgment, and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must include an expense within the tax provision in the consolidated statement of operations and comprehensive loss. Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and our valuation allowance. We have recorded a full valuation allowance against our deferred tax assets of $94.1 million as of December 31, 2004, due to uncertainties related to our ability to utilize our deferred tax assets, primarily consisting of certain net operating losses carried forward, before they expire. In assessing the need for a valuation allowance, we have considered our estimates of future taxable income, the period over which our deferred tax assets may be recoverable, our history of losses and our assessment of the probability of continuing losses in the foreseeable future. In management's estimate, any positive indicators, including forecasts of potential future profitability of our businesses, are outweighed by the uncertainties surrounding our estimates and judgments of potential future taxable income. In the event that actual results differ from theseour estimates, or we adjust these estimates should we believe we wouldsuch amounts will be able to realize these deferred tax assets in the future, an adjustment to the valuation allowance would increase incomerecorded as cumulative adjustments in the period such determination was made. Any changes in the valuation allowance could materially impactestimates are revised.  If actual results differ significantly from these estimates, stock-based compensation expense and our financial position and results of operations. VALUATION OF LONG-LIVED AND INTANGIBLE ASSETS AND GOODWILL Goodwill is evaluated for impairment using a fair value approach at the reporting unit level annually, or earlier if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. A reporting unit canoperations could be an operating segment or a business if discrete financial information is preparedmaterially impacted.
Refer to Notes 2 and reviewed by management. Our reporting units are: 1)11 to the Acacia Technologies groupResearch Corporation consolidated financial statements included in Part IV, Item 15 of this report for more information.
Valuation of Long-lived and 2) the CombiMatrix group. Under the impairment test, if a reporting unit's carrying amount exceeds its estimated fair value, goodwill impairment is recognized to the extent that the reporting unit's carrying amount of goodwill exceeds the implied fair value of the goodwill. The fair value of Acacia Research Corporation's reporting units are estimated using discounted cash flows and other valuation techniques. Significant judgments and estimates are required in determining forecasted cash inflows and outflows, the timing of cash flows and discount rates commensurate with the risks involved. Intangible Assets

We review long-lived assets, including patent related intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  Factors we consider important, which could trigger an impairment review include the following: o significant underperformance relative to expected historical or projected future operating results; o significant changes in the manner of our use of the acquired assets or the strategy for our overall business; 33 o significant negative industry or economic trends; o significant adverse changes in legal factors or in the business climate, including adverse regulatory actions or assessments; and o significant decline in our stock price for a sustained period.
·  significant underperformance relative to expected historical or projected future operating results;
·  significant changes in the manner of our use of the acquired assets or the strategy for our overall business;
·  significant negative industry or economic trends;
·  significant adverse changes in legal factors or in the business climate, including adverse regulatory actions or assessments; and
·  significant decline in our stock price for a sustained period.
We calculate estimated future undiscounted cash flows, before interest and taxes, resulting from the use of the asset and its estimated value at disposal and compare it to its carrying value in determining whether impairment potentially exists. If a potential impairment exists, a calculation is performed to determine the fair value of the long-lived asset. This calculation is based on a valuation model and discount rate commensurate with the risks involved. Third party appraised values may also be used in determining whether impairment potentially exists.

As described above, in assessing the recoverability of goodwill and other intangible assets, estimates of market values, estimates of the amount and projections regarding estimatedtiming of future cash flows, and estimates of other factors are used to determine the fair value of the respective assets. If these estimates or related projections change in future periods, future goodwillintangible asset impairment tests may result in a chargecharges to earnings.  ACCOUNTING FOR BUSINESS COMBINATIONS The cost of an acquired business is assignedRefer to Note 6 to the tangible and identifiable intangible assets acquired and liabilities assumedconsolidated financial statements, included elsewhere herein, for information on impairment charges recorded during the basisperiods presented.

Impairment of their fair values at the date of acquisition. We assess fair value using a variety of methods, including the use of present value models, independent appraisers, and estimation of current selling prices and replacement values. Amounts recorded as intangible assets, including acquired in-process research and development, or IPR&D, are based on assumptions and estimates regarding the amount and timing of projected revenues and costs, appropriate risk-adjusted discount rates, as well as assessing the competition's ability to commercialize products before we can. Also, upon acquisition, we determine the estimated economic lives of the acquired intangible assets for amortization purposes. Actual results may vary from projected results. On December 13, 2002, Acacia Research Corporation increased its consolidated ownership interest in CombiMatrix Corporation from 48% to 100% by acquiring from existing stockholders of CombiMatrix Corporation 11,987,052 shares of CombiMatrix Corporation common stock in exchange for 11,987,052 shares of AR-CombiMatrix stock with a fair value of $46.0 million. The transaction was accounted for as a step acquisition using the purchase method of accounting. Marketable Securities

The fair value of the AR-CombiMatrix stock issued in the transaction wasour investments is determined by quoted market prices.  Realized and unrealized gains and losses are recorded based on the quoted market pricespecific identification method.  We review impairments associated with our investments in marketable securities in accordance with Emerging Issues Task Force (“EITF”) 03-1 and FSP SFAS 115-1 and 124-1, “The Meaning of AR-CombiMatrix stock averaged over a five-day period (from December 16, 2002,Other-Than-Temporary-Impairment and Its Application to Certain Investments,” to determine the first dayclassification of trading for the AR-CombiMatrix stock through December 20, 2002). The total purchase price of $46.8 million, including acquisition costs of $0.8 million, was allocated to the fair value of assets acquired and liabilities assumed, including acquired in-process research and development,any impairment as “temporary” or IPR&D. The amount attributable to CombiMatrix Corporation's core technology and related patents was $5.3 million, which is being amortized using the straight-line method over the estimated economic useful life of 7 years. The amount attributable to IPR&D of $17.2 million was charged to expense and is included“other-than-temporary.”   For investments classified as available-for-sale, unrealized losses that are other than temporary are recognized in the consolidated statement of operations and comprehensive lossincome (loss) (hereinafter “consolidated statement of operations”).  An impairment is deemed other than temporary unless (a) we have the ability and intent to hold an investment for a period of time sufficient for recovery of its carrying amount and (b) positive evidence indicating that the year ended December 31, 2002. Theinvestment's carrying amount attributable to goodwill was $16.0 million. Amounts allocated to patents, IPR&D and goodwill have been attributedis recoverable within a reasonable period of time outweighs any evidence to the CombiMatrix group. As described above, $17.2 millioncontrary. All available evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, the carrying amount of the purchase price was allocatedinvestment is recoverable within a reasonable period of time.
We believe that our investments in certain auction rate securities continue to IPR&D projects that had not yet reached technological feasibility and had no alternativeapproximate their par value;  however, such risks, including the systemic failure of future use. Accordingly, this amount was immediately expensedauctions for auction rate securities, may result in a loss of liquidity, substantial impairment to our investments, realization of substantial future losses, or a complete loss of the investment in the 2002 consolidated statement of operations and comprehensive loss as of the acquisition date. Management was responsible for determining the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed, including IPR&D, at the date of acquisition. Management considered a number of factors, including reference to independent valuations. Management utilized an income approach to determine the fair values of tangible and identifiable intangible assets acquired and liabilities assumed. The in-process technologies were valued using a discounted cash flow model on a project-by-project basis,long-term which estimated the cash flows expected to result from each project once it has reached technological feasibility. A discount rate consistent with the risks of each project was used to estimate the present value of future cash flows. In estimating future cash flows, management considered the contribution of its core technology (for which a United States patent was obtained in July 2000) that would be required for successful exploitation of purchased in-process technology, in order to value the core and in-process technologies discretely. As a result, future cash flows relating to each purchased IPR&D project were reduced in order to reflect the contribution of core technology to each IPR&D project. The cash flows from these projects attributable to core technology were then separately valued to determine the intangible asset value of purchased core technology. In determining the contribution of core technology to in-process projects, management used a profit split approach which considered the estimated profit split between a licensor and licensee of the core technology and management's assessment of how critical the core technology was to the IPR&D projects. 34 The nature of the efforts to develop the purchased IPR&D into commercially viable products principally relates to the completion and/or acceleration of existing development programs. These efforts include testing current and alternative materials used in array design, testing of existing and alternative methods for array synthesis, developing prototype machinery (including operating software) to synthesize, hybridize and read individual arrays, and to perform numerous experiments, or assays, with actual target samples in order to determine customer protocols and procedures for using the CombiMatrix group's array system. The costs of these effortsmay have been included in the CombiMatrix group's projections to successfully launch the purchased IPR&D projects. The resulting net cash flows from such projects are based on management's estimates of revenues, cost of sales, research and development expenses, sales and marketing expenses, general and administrative expenses, the anticipated effect of income taxes, and required returns on working capital, fixed assets and other assets necessary to support the generation of these cash flows. The discounting of net cash flows relating to core technology to their present value is based on CombiMatrix Corporation's weighted average cost of capital, or WACC. The WACC calculation produces the average required rate of return of an investment in an operating enterprise, based on various required rates of return from investments in various areas of that enterprise. The WACC for CombiMatrix Corporation was approximately 20% at the time of the merger and is the rate used in discounting the net cash flows attributable to purchased core technology. Due to the additional inherent risks associated with the purchased IPR&D projects, including if and when the technologies will ultimately become commercially viable, market acceptance risks, and threats from competing technologies, higher discount rates were used to value the projects. The discount rates used for each project are described below. The forecast data employed in the valuation analyses was based upon product level forecast information obtained by Acacia Research Corporation from numerous internal and external resources. These resources included publicly available databases, external market research consultants, company-sponsored focus groups and internal market experts. Management reviewed and challenged the forecast data and related assumptions and utilized the information in analyzing IPR&D. The forecast data and assumptions are inherently uncertain and unpredictable. However, based upon the information available at this time, Acacia Research Corporation management believes the forecast data and assumptions to be reasonable. These assumptions may be incomplete or inaccurate and no assurance can be given that unanticipated events and circumstances will not occur. Accordingly, actual results may vary from the forecasted results. Any such variance may result in a material adverse effect on Acacia Research Corporation's financial condition andour business, results of operations. In the allocationoperations, liquidity, and financial condition.  See Note 2 of purchase priceour Notes to the IPR&D, the concept of alternative future use was specifically consideredConsolidated Financial Statements for each of the programs under development. The acquired IPR&D consists of CombiMatrix Corporation's work to complete each of the identified programs. The programs are very specific to research market for which they are intended. There are no alternative uses for the in-process programsadditional details about our investments in the event that the programs fail in their continued development or are otherwise not feasible. The development effort for the acquired IPR&D does not possess an alternative future use for auction rate securities and other marketable securities.

Acacia Research Corporation as defined by generally accepted accounting principles. Following is a brief description
Results of each IPR&D project. GENOMICS BIOLOGICAL ARRAY SYSTEM: CombiMatrix Corporation's genomics biological array processor system is being developed to discretely immobilize sequences of DNA or RNA within individual test sites on a modified semiconductor chip coated with a three-dimensional layer of porous material. The system also includes proprietary hardware units and related software applications to be able to synthesize materials onto the chips, apply target samples of genetic materials and interpret the results. The application of this system will be in gene expression profiling and SNP genotyping, which could lead to the better understanding of gene function and ultimately therapeutic discovery to fight disease. CombiMatrix Corporation's projected cash flow models from commercializing this system include servicing CombiMatrix Corporation's existing relationship with Roche as well as other strategic partners, including pharmaceutical, biotech and academic institutions. The fair value assigned to the genomics biological array system IPR&D project was $14.0 million. A risk-adjusted discount rate of 32% was applied to the project's estimated cash flows. The CombiMatrix group is substantially complete with the Genomics IPR&D project contemplated at the acquisition date and launched its CustomArray(TM) DNA Microarray platform in March 2004. 35 PROTEOMICS BIOLOGICAL ARRAY SYSTEM: CombiMatrix Corporation's proteomics biological array processor system is being developed to discretely immobilize proteins and other small molecules within individual test sites on a modified semiconductor chip in a similar fashion as described above for the genomics biological array system. However, the porous reaction layer coating used in synthesis and manner in which the software used to design probes for protein immobilization are significantly different from what is currently being developed for the genomics application. Further, the proteomics biological array system primarily uses electrochemical methods for detection of assay results, which contrasts with the optical means that are the primary method used with the CombiMatrix Corporation's genomics products. These differences arise largely due to the inherent biological differences between DNA molecules and protein molecules and how they interact with the CombiMatrix group's proprietary technology. The proteomics biological array system is used for detection and identification of bio-threat agents in CombiMatrix Corporation's biological and chemical threat agent detector development programs that are currently in process. Although ongoing research and development efforts in commercializing this system have been positive, there can be no assurance that the system will be successfully launched and accepted by the government, pharmaceutical, biotech and academic research fields. The fair value assigned to the proteomics biological array system IPR&D project was $3.2 million. A risk- adjusted discount rate of 60% was applied to the project's estimated cash flows. The Proteomics IPR&D project is ongoing as projected and the expected completion of the project coincides with the expected completion of the CombiMatrix group's obligations under its $5.9 million Department of Defense contract to further the development of the CombiMatrix group's microarray technology for the detection of biological threat agents. The Department of Defense contract was approximately 34% complete as of December 31, 2004. Based on actual costs incurred through December 31, 2004, the CombiMatrix group expects to incur approximately $2.2 million and $819,000 in research and development costs during 2005 and 2006, respectively, to complete its obligations to the Department of Defense under this contract. The CombiMatrix group has also contracted with strategic partners such as Toppan and Furuno to further develop aspects of its genomics array platform and continues to invest internally to develop and launch new products. Such activities are consistent with the original projections. MANAGEMENT AND ALLOCATION POLICIES RELATING TO AR-ACACIA TECHNOLOGIES STOCK AND AR-COMBIMATRIX STOCK The management and allocation policies applicable to the preparation of the divisional financial statements of the CombiMatrix group and the Acacia Technologies group (collectively, the "groups") may be modified or rescinded, or additional policies may be adopted, at the sole discretion of the Acacia Research Corporation board of directors at any time without approval of the stockholders. The group divisional financial statements reflect the application of the management and allocation policies adopted by the Acacia Research Corporation board of directors to various corporate activities, as described below. The group's divisional financial statements should be read in conjunction with Acacia Research Corporation's consolidated financial statements and related notes. CORPORATE GENERAL AND ADMINISTRATIVE SERVICES AND FACILITIES Acacia Research Corporation allocates the cost of corporate general and administrative services and facilities between the groups generally based upon utilization. Where determinations based on utilization alone are impracticable, Acacia Research Corporation uses other methods and criteria, which require the use of judgments and estimates, that management believes to be equitable and to provide a reasonable estimate of the cost attributable to each group. Except as otherwise determined by management, the allocated costs of providing such services and facilities include, without limitation, all costs and expenses of personnel employed in connection with such services and facilities, including, without limitation, all direct costs of such personnel, such as payroll, payroll taxes and fringe benefit costs (calculated at the appropriate annual composite rate therefore) and all overhead costs and expenses directly related to such personnel and the services or facilities provided by them. The corporate general and administrative services and facilities allocated between the groups include, without limitation, legal services, accounting services (tax and financial), insurance and deductibles payable in connection therewith, employee benefit plans and administration thereof, investor relations, stockholder services and services relating to the Acacia Research Corporation board of directors. Refer to Note 2 in the consolidated financial statements for details on allocation methodologies used to allocate costs between the two groups. 36 ACACIA RESEARCH CORPORATION CONSOLIDATED RESULTS OF OPERATIONS NET LOSS (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Net loss .............................................. $ (4,833) $ (24,420) $ (58,973)

License Fees. Revenues for 2007 included license fees from 91 new licensing agreements covering 16 of its researchour technology licensing and development agreement with Roche. As a resultenforcement programs, as compared to 72 new licensing agreements covering 14 of completing all obligations under this agreementour technology licensing and enforcement programs in accordance with the CombiMatrix group's revenue recognition policies for multiple-element arrangements, the CombiMatrix group recognized $17.3 million2006, and 83 new licensing agreements covering 12 of researchour technology licensing and development contract revenues during the first quarter of 2004, all of which were previously deferred.enforcement programs in 2005.  The majority of research and development efforts under the Roche agreement were incurred prior to 2004. LICENSE FEES. Licenseincrease in license fee revenues are comprisedin 2007 and 2006, as compared to 2005, reflects the impact of DMT technology license feesthe increase in patent portfolios owned or controlled by our operating subsidiaries since 2005, and previously deferred V-chip technology license fees recognized by the Acacia Technologies group. DMT technology license fees were $2.8 million and $692,000 in 2004 and 2003, respectively. Therelated increase was primarily due to the significant growth in the number of DMT technology license agreements executedpatent licensing and enforcement programs developed, launched and generating revenues since March2005.  On a consolidated basis, as of December 31, 2003. During 2004, we executed 170 DMT license agreements.2007, 28 of our licensing programs had begun generating licensing revenues, up from 20 as of December 31, 2006 and 13 as of December 31, 2005.  License fee revenues willrecognized by our operating subsidiaries fluctuate from period to period primarily based on the increase in license agreements executed, fluctuations in the sales results or other royalty per unit activities of our licensees that impact the calculation of license fees due, the timing of the receipt of periodic license fee statements and or payments from licensees, and other factors. Periodic license fee revenues may include amounts that relate to prior license periods or prior periods of infringement, which are recognized as revenues in the period received. DMT license fees related to prior periods of infringement for the periods presented above were not significant. following factors:
·   the dollar amount of agreements executed each period, which is primarily driven by the nature and characteristics of the technology being licensed and the magnitude of infringement associated with a specific licensee;
·   the specific terms and conditions of agreements executed each period and the periods of infringement contemplated by the respective payments;
·   fluctuations in the total number of agreements executed;
·   fluctuations in the sales results or other royalty per unit activities of our licensees that impact the calculation of license fees due;
·   the timing of the receipt of periodic license fee payments and/or reports from licensees; and
·   fluctuations in the net number of active licensees period to period.

Costs incurred in connection with the Acacia Technologies group's ongoingour operating subsidiaries licensing and enforcement activities, other than inventor royalties expense, contingent legal fees expense and patent-related legal expenses, are included in marketing, general and administrative expenses.

Marketing, General and Administrative Expenses.  Marketing, general and administrative expenses consist of compensation and related personnel costs including non-cash stock compensation expenses, office and facilities costs, legal and accounting professional fees, public relations, marketing, stock administration and other corporate costs, and patent related development, commercialization, research, consulting and maintenance costs.

Excluding the impact of non-cash stock compensation charges discussed below, the net increase for the periods presented was due primarily to the addition of licensing, business development and engineering personnel and an increase in other personnel related expenses in each comparable period, a one-time severance charge for an employee separation under the Acacia Research Corporation Executive Severance Plan in the first quarter of 2007, an increase in patent acquisition and business development related research and consulting costs and an increase in corporate, general and administrative costs, including an increase in accounting fees related to the CombiMatrix Split-off Transaction.  The overall increase in marketing, general and administrative expenses is reflective of the continued growth and expansion of our intellectual property acquisition, licensing and enforcement business conducted by our operating subsidiaries and related ongoing operations.   In 2007, as compared to 2006, these increases were partially offset by a decrease in consulting expenses due to the expiration of the consulting agreement with the former CEO of Global Patent Holdings, LLC in January 2007.  The increases in 2006, as compared to 2005, were partially offset by a reduction in Acacia Research Corporation’s Sarbanes-Oxley compliance costs.

23

Non-cash stock compensation charges increased during 2007, as compared to 2006, due to the issuance of equity based incentive awards to new and existing employees during 2007.  In addition, the increase in non-cash stock compensation expense also reflects the increase in the AR-Acacia Technologies stock price during 2007, as compared to 2006, as illustrated at Item 5. “Recent Market Prices” above.  The weighted average fair value of stock options granted during 2007 and 2006 was $9.07 and $5.35, respectively.  The weighted average fair value of nonvested restricted shares granted during 2007 and 2006 was $14.04 and $11.87, respectively (see Note 11 to the consolidated financial statements for information on the determination of fair value for share based awards under SFAS No. 123R).  The increase in non-cash stock compensation charges in 2006, as compared to 2005, reflects our adoption of SFAS No. 123R, effective January 1, 2006, which required public companies to measure all employee stock-based compensation awards using a fair-value method and record such expense in their consolidated financial statements, as described under “Critical Accounting Estimates.”

A summary of the main drivers of the change in marketing, general and administrative expenses, including the impact of non-cash stock compensation charges, for the periods presented, is as follows (in thousands):
  2007 vs. 2006  2006 vs. 2005

Inventor Royalties and Contingent Legal Fees Expense.  Inventor royalties expense totaled $12.1 million and $9.6 million in 2007 and 2006, respectively, and contingent legal fees expense totaled $17.2 million and $7.5 million in 2007 and 2006, respectively.  Inventor royalties expenses and contingent legal fees expenses for the periods presented were incurred in connection with the recognition of the related license fee revenues, summarized above.  The majority of the patent portfolios owned or controlled by our operating subsidiaries are subject to patent and patent rights agreements with inventors containing provisions granting to the original patent owner the right to receive inventor royalties based on future net revenues, as defined in the respective agreements, and may also be subject to contingent legal fee arrangements with external law firms engaged on a contingent fee basis.  The economic terms of the inventor and contingent fee arrangements, if any, vary across our patent portfolios.  As such, inventor royalties and contingent legal fee expenses fluctuate period to period based on the amount of revenues recognized each period and the mix of specific patent portfolios, with varying economic terms, generating revenues each period.

The increase in inventor royalties expense and contingent legal fees expense in 2007 was due in part to the increase in license fee revenues recognized in 2007, as compared to 2006, as discussed above, and also reflects the impact of the mix of patent portfolios with varying economic terms generating the revenues during the respective periods.  A portion of 2006 revenues were comprised of license fees from patent portfolios that were not subject to a contingent legal fee arrangement, whereas the majority of patent portfolios generating revenues in 2007 were subject to contingent legal fee arrangements.  As a result, in 2006, no contingent legal fees expense was incurred on a portion of revenues, resulting in the 128% increase in contingent legal fees expense in 2007, as compared to 2006, as compared to 51% increase in license fee revenues for 2004 include $1.5 millionthe same periods.

Results in previously deferred2005 included $225,000 of V-chip license fees (originally deferred in 2001)related inventor royalties expense recognized as a result of the conclusion of all V-chip related litigation activities in August 2004, as described at Item 3. "Legal Proceedings." We concluded our V-chipOctober of 2005.

Legal Expense – Patents. Patent-related legal expenses include patent-related prosecution and enforcement costs incurred by outside law firms engaged on an hourly basis and the out-of-pocket expenses incurred by outside law firms engaged on a contingent fee basis.  Patent-related legal expenses fluctuate from period to period based on patent enforcement and prosecution activity associated with ongoing licensing program in August 2004 and do not expect to receive any additional V-chip related revenues in future periods. GOVERNMENT CONTRACT AND COST OF GOVERNMENT CONTRACT REVENUES. In March 2004,enforcement programs and the CombiMatrix group executed a two-year $5.9 million research and development contract with the Department of Defense to further the developmenttiming of the CombiMatrix group's array technologycommencement of new licensing and enforcement programs in each period.  Patent-related legal expenses include case related costs billed by outside counsel for discovery, depositions, economic analyses, damages assessments, expert witnesses and other consultants, case related audio/video presentations for the detectioncourt, and other litigation support and administrative costs.

24

The increase in patent related legal expenses in 2007, as compared to 2006,  is primarily due to a net increase in ongoing patent enforcement litigation and an increase in litigation support related out of biological threat agents. Under the terms of the contract, the CombiMatrix group is reimbursed on a periodic basis for actual costs incurred to perform its obligations, plus a fixed fee. Revenues are recognized under the percentage-of-completion method of accounting, using the cost-to-cost approach to measure completeness at the end of each reporting period. Cost of government contract revenues reflect researchpocket expenses, third party technical consulting expenses and developmentprofessional expert expenses incurred in connection with certain of our patent portfolios that are further along in the CombiMatrix group's commitments under its biowarfare detection contractprosecution of the related litigation and certain of our patent portfolios that have proceeded to trial and concluded.  The increase in patent related legal expenses in 2006, as compared to 2005, is primarily due to a net increase in ongoing patent enforcement litigation in each respective period, and to a lesser extent, an increase in the number of portfolios where we have engaged outside law firms on an hourly or discounted hourly basis.

We expect patent-related legal expenses to continue to fluctuate period to period based on the factors summarized above, in connection with current and future patent commercialization and enforcement programs.

Amortization of Patents.  The increase in 2007, as compared to 2006, was due to additional patent amortization charges related to certain patent portfolios acquired by our operating subsidiaries in late 2006 and throughout 2007.  Patent amortization charges will continue to be significant in future periods as we continue to amortize the Departmentacquired patent related costs over a weighted-average remaining economic useful life of Defense, whichapproximately four years.

The increase in 2006, as compared to 2005, was approximately 34% completedue to twelve full months of patent amortization expense resulting from the GPH Acquisition in 2006, as compared to 11 months of December 31, 2004. Based on actualamortization in 2005.  Patent amortization expense related to the GPH Acquisition was $4.7 million and $4.4 million in 2006 and 2005, respectively.  In addition, patent amortization expense in 2006 and 2005 includes additional patent amortization charges related to certain of the patent portfolios acquired by our operating subsidiaries subsequent to the GPH Acquisition.

Refer to “Liquidity and Capital Resources” below for patent portfolio acquisition costs incurred through December 31, 2004,during the CombiMatrix group expects to incur approximately $2.2 million and $819,000 in research and development costs during 2005 and 2006, respectively, to complete its obligationsperiods presented.

Write-off of Patent-related Intangible Asset.  In September 2007, we recorded a non-cash impairment charge of $235,000, related to the Departmentwrite-off of Defense under this contract. 37 Government contract revenues in 2002 included amounts earned from the CombiMatrix group's performance under its Phase I SBIR Department of Defense contract, Phase I NIH grant and one-time contract research and development revenues.a patent-related intangible asset.  The SBIR Department of Defense and NIH grants wererelated licensing program was completed during the third quarter of 2002.

Discontinued Operations – Split-off of CombiMatrix group's array products. TheCorporation

In January 2006, Acacia Research Corporation’s board of directors approved a plan for its wholly owned subsidiary, CombiMatrix group launched its CustomArray(TM) 902 DNA array platformCorporation, to become an independent public company.  CombiMatrix Corporation’s registration statement on Form S-1 was declared effective by the SEC on June 8, 2007.  Following the redemption period required by Acacia Research Corporation’s Restated Certificate of Incorporation, on August 15, 2007 (the “Redemption Date”), CombiMatrix Corporation was split-off from Acacia Research Corporation through the redemption of all outstanding shares of AR-CombiMatrix common stock in March 2004 and its CustomArray(TM) 12K DNA expression array in July 2004. Product revenues and costexchange for the distribution of product sales during 2003 and 2002 were recognized bynew shares of CombiMatrix K.K. from sales of DNA array synthesizers and related array products and services to Japanese research institutions. RESEARCH AND DEVELOPMENT EXPENSES (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Research and development expenses ..................... $ 5,294 $ 8,098 $ 18,187 Charge for acquired in-process research and development .............................. - - 17,237
RESEARCH AND DEVELOPMENT EXPENSES. The decrease in research and development expenses in 2004, as compared to 2003 and 2002, was primarily dueCorporation, on a pro-rata basis, to the CombiMatrix group's completionholders of several Roche related research and development projects during the third and fourth quarters of 2003, and final completionAR-CombiMatrix stock as of the research and development agreement with Roche inRedemption Date (the “Split-off Transaction”).  On the first quarterRedemption Date, every ten (10) shares of 2004. During 2003 and 2002,AR-CombiMatrix stock outstanding on August 15, 2007, was redeemed for one (1) share of common stock of CombiMatrix Corporation.  Subsequent to the CombiMatrix group's research and development activities were driven primarily by ongoing performance obligations under the product commercialization phase of its license and research and development agreements with Roche. These activities include costs associated with direct labor, supplies and materials, development of prototype arrays and instruments and the use of outside consultants for certain engineering efforts. With the completion of the research and development agreement with Roche, year-to-date and future research and development expenses were and will continue to be incurred in connection with the CombiMatrix group's commitments under its collaboration and supply agreements with various strategic partners including Furuno and Toppan, as well as ongoing internal research and development efforts in the areas of genomics, drug discovery and development and material sciences. The CombiMatrix group expects its research and development expenses to continue to be volatile and such expenses could increase in future periods as additional contract and/or internal research and development agreements are undertaken. CHARGE FOR ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT. Operating expenses in 2002 include a non-cash charge for acquired in-process research and development of $17.2 million, related toRedemption Date, Acacia Research Corporation's purchase of the stockholderCorporation no longer owns any equity interests in CombiMatrix Corporation and the two companies operate independently of each other.

As a result of the Split-off Transaction, the assets, liabilities, results of operations and cash flows of CombiMatrix Corporation have been eliminated from the continuing operations of Acacia Research Corporation and Acacia Research Corporation does not have any continuing involvement in the operations of CombiMatrix Corporation.  As a result of the Split-off Transaction, we have disposed of our investment in CombiMatrix Corporation, and therefore, in accordance with guidance set forth in SFAS No. 144, Acacia Research Corporation’s accompanying consolidated balance sheets, statements of operations and statements of cash flows for the current period presented reflect the assets, liabilities, results of operations and cash flows for CombiMatrix Corporation as discontinued operations.  Consolidated financial statements presented for the comparable prior year periods have been restated to conform to this presentation.  CombiMatrix Corporation was previously presented as a separate operating segment of Acacia Research Corporation under SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.”

The Split-off Transaction was accounted for by Acacia Research Corporation at historical cost.  Accordingly, no gain or loss on disposal was recognized in the accompanying consolidated statements of operations. Included in the current period consolidated balance sheet is a charge to consolidated shareholders’ equity totaling $35,444,000, reflecting the distribution of our investment in the net assets of CombiMatrix Corporation to holders of AR-CombiMatrix stock, as of the Redemption Date, as described above.  We received a private letter ruling from the IRS with regard to the U.S. federal income tax consequences of the Split-off Transaction to the effect that we did not already own in December 2002. See "Critical Accounting policies" abovethe Split-Transaction will be treated as a tax-free exchange under Sections 368 and 355 of the Internal Revenue Code of 1986, as amended.

Other Discontinued Operations.  Results for acquired in-process research and development. MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES AND LEGAL SETTLEMENT CHARGES (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Marketing, general and administrative expenses ........ $ 14,426 $ 13,031 $ 17,217 Legal expenses - patents .............................. 3,133 1,886 1,415 Legal settlement charges .............................. 812 144 18,471
MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES. The change in 2004, as compared to 2003, was due primarily to an increase in personnel costs2005 include charges, net of minority interests, of $237,000 related to the addition of patent licensing and business development personnel for the Acacia Technologies group of $418,000, an increase in the Acacia Technologies group's patent related commercialization expenses of $110,000, an increase in corporate professional fees relatedestimated additional costs to ongoing Sarbanes-Oxley compliance projects at both operating groups of $621,000 and an increase in marketing and sales costs of $447,000 related to the launch of the CombiMatrix group's CustomArray(TM) DNA array platform beginning in March 2004 and the overall expansion of the CombiMatrix group's sales and marketing division. The change in 2003, as compared to 2002, was due primarily to a decrease in the CombiMatrix group's corporate legal expenses of approximately $827,000, primarily related to the settlement of litigation with Nanogen, a decrease in legal, accounting and other professional fees related to Acacia Research Corporation's recapitalization and merger transactions completed in December 2002 of $2.0 million, a decrease in marketing and sales personnel costs, primarily for the CombiMatrix group, and general and administrative personnel 38 costs for both groups of $1.2 million and a decrease in other general and administrative costs of $578,000. This decrease was partially offset by an increase in the CombiMatrix group's rent and utilities expenses of $473,000, as a result of the increase in occupancy of its corporate headquarters in Mukilteo, Washington during 2003, and an increase in costs related to the Acacia Technologies group's ongoing DMT patent commercialization and enforcement efforts of $219,000, including increased consulting and engineering costs related to new patent claims, enforcement and the identification of additional potential licensees of our DMT technology. LEGAL EXPENSE - PATENTS (ACACIA TECHNOLOGIES GROUP ONLY). Patent related legal expenses in 2004 included $668,000 in deferred V-chip related legal fees recognized as a result of the conclusion of V-chip related litigation in August 2004, as described at Item 3. "Legal Proceedings." The Acacia Technologies group's patent related legal expenses, excluding V-chip related legal fees, increased to $2.5 million during 2004, as compared to $1.9 million, and $1.4 million in the comparable 2003 and 2002 periods, due to an increase in costsbe incurred in connection with the Acacia Technologies group's ongoing DMT patent commercializationdiscontinued operations of Soundbreak.com (originally ceased operations in February 2001), related primarily to certain noncancellable lease obligations and enforcement programs, including increased legal costsa reduction in estimated amounts recoverable from existing sublease arrangements.  The related to new patent claims and the identification of additional potential licensees of our DMT technology and increased patent enforcement costs related to ongoing DMT patent related litigation. See Item 3. "Legal Proceedings" for a description of ongoing DMT related litigation. We expect patent related legal expenses to continue to fluctuate based on actual outside patent counsel fees incurred in connection with the Acacia Technologies group's ongoing DMT and other patent commercialization and enforcement programs. DMT related legal fees to outside attorneys are charged based on actual time and out-of-pocket expenses incurredlease obligations, which were guaranteed by external counsel and are not incurred on a contingent fee basis. In connection with the January 2005 acquisition as described above, we acquired 27 additional patent portfolios. Although most litigation with respect to those portfolios is likely to be handled on a contingency basis where attorneys fees are paid out of license fee revenues collected, certain other costs and expenses in connection with our maintenance, licensing, and enforcement of patents are likely to increase as a result of the acquisition including patent filing fees, patent development costs, travel costs, expert and consulting fees, and other third-party expenses. LEGAL SETTLEMENT CHARGES. In 2002, in connection with the September 2002 settlement agreement between CombiMatrix Corporation, Dr. Donald Montgomery, and Nanogen (see Note 13 to the Acacia Research Corporation, consolidated financial statements included elsewhere herein), the CombiMatrix group expensed a $1.0 million payment to Nanogen and recorded a non-cash chargeexpired in the amount of $17.5 million related to the fair value of CombiMatrix Corporation common shares issued to Nanogen. In addition, the CombiMatrix group recorded a net non-cash charge totaling $812,000 during 2004, which reflects the fair value of AR-CombiMatrix common stock issued and potentially issuable to Nanogen, Inc. during the period in connection with certain anti-dilution provisions of the settlement agreement. Periodic charges and the related liability are estimated based on the number of shares issuable and or potentially issuable and the AR-CombiMatrix stock price at the end of the respective reporting period. The anti-dilution provisions of the settlement agreement expire in SeptemberAugust 2005. NON-CASH STOCK COMPENSATION AMORTIZATION (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Non-cash stock compensation amortization: Research and development ............................ $ 91 $ 466 $ 1,868 Marketing, general and administrative ............... 663 1,189 4,559
The decrease in the CombiMatrix group's non-cash stock compensation amortization was primarily due to the accelerated method of stock compensation amortization utilized, which results in higher amounts of amortization in the earlier vesting periods and the impact of non-cash stock compensation expense reversals related to the forfeiture of certain unvested stock options during the respective periods. Non-cash stock compensation expense reversals totaled $185,000 in 2004 and $1.2 million in both 2003 and 2002. Non-cash deferred stock compensation amounts were fully amortized as of December 31, 2004. IMPAIRMENT CHARGES (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Goodwill impairment charge ............................ $ (1,656) $ - $ - Impairment of cost method investment .................. - (207) (2,748)
39 GOODWILL IMPAIRMENT CHARGE. In August 2004, as a result of the adverse ruling in the Soundview Technologies litigation described at Item 3. "Legal Proceedings," the Acacia Technologies group recorded a non-cash impairment charge, included in operating expenses, totaling $1.6 million associated with the write-down of 100% of the goodwill related to the V-chip. IMPAIRMENT OF COST METHOD INVESTMENT. In 2003, we recorded an impairment charge of $207,000 for an other-than-temporary decline in the fair value of our cost method investment. Impairment indicators included a continued decline in the working capital of the entity and reference to a recent equity transaction and related valuation indicating an other-than-temporary decline in fair value of the investment. In 2002, we recorded an impairment charge of $2.7 million for an other-than-temporary decline in the fair value of the same cost method investment. Impairment indicators included recurring losses, a decline in working capital and the completion of a recent equity transaction at an amount below our carrying value. AMORTIZATION OF PATENTS (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Amortization of patents ............................... $ 1,597 $ 1,597 $ 1,990
The decrease in 2003, as compared to 2002, was due to a reduction in patent amortization expense due to V-chip technology related patent costs and other intangibles that were fully amortized during 2002. With the acquisition of the assets of Global Patent Holdings, as described above, we expect that a significant portion of the approximated $25.0 million purchase price will be allocated to the patents acquired, which will be amortized over the estimated economic useful lives of the respective patents, resulting in increased amortization charges in 2005 and future periods. See Note 15 to the Acacia Research Corporation consolidated financial statements for additional information. REALIZED AND UNREALIZED GAINS/LOSSES (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Realized gains (losses) on short-term investments ..... - 94 (1,184) Unrealized losses on short-term investments ........... - - (249)
The decrease in the Acacia Technologies group's realized and unrealized gains/losses on short-term investments was due to no investments classified as trading securities held during 2004 and 2003 and the sale of the balance the Acacia Technologies group's trading securities during 2002. INCOME TAXES (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Benefit for income taxes .............................. $ 275 $ 273 $ 857
The 2004, 2003 and 2002 income tax benefits primarily reflect the impact of the reversal of deferred tax liabilities related to the amortization of identifiable intangible assets related to certain of Acacia Research Corporation's step acquisitions in 2002, 2001 and 2000. $569,000 of the 2002 income tax benefit also reflects the impact of differences between the 2001 income tax provision and Acacia Research Corporation's final 2001 consolidated tax return filed in September 2002, and is the result of additional deductions against Soundview Technologies taxable income. MINORITY INTERESTS (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Minority interests .................................... $ 6 $ 47 $ 23,806
The decrease is due to Acacia Research Corporation's acquisition of the remaining ownership interests in Soundview and Acacia Media Technologies in 2001, CombiMatrix Corporation in December 2002, and CombiMatrix K.K. in July 2003 and approximately 99% of the remaining ownership interests in Advanced Material Sciences in July 2003.

Liquidity and Capital Resources

Acacia Research Corporation'sCorporation’s consolidated cash and cash equivalents along withand short-term investments totaled $52.4$51.4 million at December 31, 2004,2007, compared to $50.5$45.0 million at December 31, 2003.2006. Working capital, related to continuing operations, at December 31, 20042007 was $49.2$48.1 million, compared to $31.1$42.2 million at December 31, 2003. At December 31, 2003 working capital included $17.7 million in deferred revenues primarily related to the CombiMatrix group's agreements with Roche and Toppan, which are not subject to any refund or repayment obligations and do not represent payment obligations of Acacia Research Corporation. 2006.

The increase in working capital in 2004 was due primarily to the recognition of $17.3 million in deferred Roche related contract revenues in the first quarter of 2004 and the impact of net cash flow activities as discussed below. The changeschange in cash and cash equivalents and short-term investments related to continuing operations for 2004, 20032007, 2006 and 2002 were2005 was comprised of the following (in thousands): YEAR ENDED DECEMBER 31, 2004 YEAR ENDED DECEMBER 31, 2003 ------------------------------------------ ------------------------------------------ ACACIA ACACIA TECHNOLOGIES COMBIMATRIX TECHNOLOGIES COMBIMATRIX GROUP GROUP CONSOLIDATED GROUP GROUP CONSOLIDATED ----------- ----------- ------------ ----------- ----------- ------------ Net cash provided by (used in) continuing operations: Operating activities ..................... $ (3,232) $ (11,584) $ (14,816) $ (5,264) $ (3,910) $ (9,174) Investing activities .....................

Operating Activities. License fee payments received from licensees increased to $51.4 million in 2007, compared to $38.6 million in 2006, reflecting the increase in net cash outflows from operations for the CombiMatrix grouplicense fee revenues recognized in 2004,2007, as compared to 2003,2006, as discussed above.  The decrease in consolidated net cash inflows from operations in 2007, as compared to 2006, was primarily due to a decreasethe increases in operating cash receipts from customers, which totaled $3.0 million in 2004, comprised of $1.7 million from the Department of Defense, $1.0 million from Furunopatent-related legal expenses, personnel expenses, and $265,000 from the sale of array productsother corporate, general and related services, compared to $12.8 million in the comparable 2003 period, consisting primarily of $9.8 million related to the completion of certain milestones and delivery of prototype products and services pursuant to its agreements with Roche and an up-front payment of $1.0 million and a $1.4 million milestone payment pursuant to its agreement with Toppan. The decrease in payments from customers was partially offset by the decrease in the CombiMatrix group's operatingadministrative expenses, as described above, and the impact of the timing of the receipt of payments from customers and payments to inventors, attorneys and other vendors. Consolidated accounts receivable increased to $1.4 million at December 31, 2007, compared to $269,000 at December 31, 2006.  The majority of accounts receivable from licensees at December 31, 2007 was collected in January 2008, in accordance with the terms of the related underlying license agreements.
The change to consolidated net cash inflows from operations in 2006, as compared to net cash outflows from operations for the Acacia Technologies groupin 2005, was primarily due to anthe increase in DMT license fee payments received from licensees, which totaled $3.1$38.6 million in 2004, as2006, compared to $665,000,$15.6 million in 2003, which2005.  The increase in license fee revenues in 2006 was partially offset by the increaseincreases in marketing,inventor royalties expenses, contingent legal fees expenses, patent-related legal expenses, personnel expenses, and other corporate, general and administrative and patent related research, commercialization and legal expenses, as described above, and the impact of the timing of vendor payments. The decrease in net cash outflows from operations in 2003, as comparedpayments to 2002, was primarily attributableinventors, attorneys and other vendors.  Consolidated accounts receivable decreased to the reduction in research and development expenses incurred by the CombiMatrix group and the decrease in consolidated marketing, general and administrative expenses, which were partially offset by the impact of the timing of vendor payments. The change was also due to an increase in operating cash receipts during 2003 from Roche and Toppan, as discussed above. Toppan related cash payments are included in deferred revenues$269,000 at December 31, 2004 and 2003. In 2002,2006, compared to $4.4 million at December 31, 2005, due to the operating cash receipts were primarily from Roche, totaling $11.6 million. collection of license fees receivable at December 31, 2005, during the first quarter of 2006, in accordance with the terms of the related underlying license agreements.

Investing Activities. The change in net cash flows used in investing activities was due primarily to Acacia Research Corporation'sfor the periods presented reflects fluctuations in net purchases and sales of available-for-sale investments in connection with ongoing short-term cash management activities.  Short-term investments represent capital available to fund current operations and fund capital expenditures.  Net cash outflows from investing activities for 2005 also included the impact of cash consideration and changes in short term investmentsrelated acquisition and registration costs, totaling $5.8 million, paid by Acacia Global Acquisition Corporation, in connection with the GPH Acquisition in the first quarter of 2005.  In addition, certain financing activities discussed below. Fixed asset purchases were $891,000, $86,000of our operating subsidiaries incurred patent acquisition costs of $3.8 million, $1.0 million and $1.1 million$445,000 in 2004, 20032007, 2006 and 2002, respectively. The change in2005, respectively, related to the acquisition of additional patent portfolios, as described earlier.

Financing Activities.  Consolidated net cash flows provided byinflows from financing activities in 2004, as compared to 2003, was due to the completion of an equity financing which raised2005 included net proceeds of approximately $13.7$19.5 million, throughrelated to the sale of 3.5 million shares of AR–Acacia Research - - CombiMatrix commonTechnologies stock during 2004, compared to equity financing net proceeds of $4.9 million during the comparable 2003 period. Financing activities in 2004 also included proceeds, primarilyFebruary 2005.  Net cash inflows from the exercise of Acacia Research - CombiMatrix common stock warrants and stock options, totaling $5.2 million, compared to $1.1 million in the comparable 2003 period. Net proceeds from the sale of Acacia Research-CombiMatrix common stock, or AR-CombiMatrix stock, were attributed to the CombiMatrix group. Cash used in financing activities in 2002 was comprised primarily of payments on the CombiMatrix group's capital lease obligation totaling $2.8 million (the capital lease obligation was paid in full in November 2002)2007, 2006 and net capital distributions to minority shareholders of subsidiaries of $318,000, which were partially offset by proceeds from2005 also included stock option exercises of $242,000. In February 2005, Acacia Research Corporation raised grossexercise proceeds of $19.6$5.0 million, through the sale of 3,500,000 shares of Acacia Research - Acacia Technologies common stock at a price of $5.60 per share in a registered direct offering. Net proceeds raised of approximately $19.58 million, which are net of related issuance costs, were attributed to the Acacia Technologies group. All of the shares of Acacia Research-Acacia Technologies common stock were offered pursuant to an effective shelf registration statement previously filed with the Securities and Exchange Commission. Total maximum proceeds of the shelf registration are $50 million, of which $15.4 million remains available subsequent to the February 2005 direct offering described above. 41 We have sustained losses since our inception contributing to an accumulated deficit of $188.2 million on a consolidated basis, which includes net losses of $4.8 million, $24.4$1.5 million, and $59.0 million 2004, 2003 and 2002,$304,000, respectively. Net losses include significant non-cash acquired in-process research and development, litigation and stock compensation charges as reflected in the accompanying Acacia Research Corporation consolidated results of operations data for 2004, 2003 and 2002. The consolidated accumulated deficit includes a non-cash increase related to a reclassification of accumulated deficit in the amount of $21.7 million to permanent capital representing the fair value of the ten percent (10%) stock dividend distributed to stockholders in 2001. There can be no assurance that we will become profitable. If we do, we may never be able to sustain profitability. We expect to incur losses for the foreseeable future. We continue to closely monitor and manage operating expenses and capital expenditures and may take steps to raise additional capital.

Management believes that ourAcacia Research Corporation’s consolidated cash and cash equivalent balances, including the net proceeds of the February 2005 equity financing and related availability under the shelf registration statement described above, anticipated cash flow from operations and other external sources of available credit, will be sufficient to meet ourits cash requirements through at least March 2009 and for the next twelve months. There can be no assurances that we will notforeseeable future.  Acacia Research Corporation and its subsidiaries may however encounter unforeseen difficulties that may deplete our capital resources more rapidly than anticipated.anticipated, including those set forth in Item 1A. “Risk Factors” included elsewhere herein.  Any efforts to seek additional funding could be made through equity, debt or other external financing and there can be no assurance that additional funding will be available on favorable terms, if at all. If weAcacia Research Corporation and its subsidiaries fail to obtain additional funding when needed, they may not be able to execute their business plans and their businesses may suffer. Refer to the “Liquidity and Risks” discussion included in Note 1 to the Acacia Research Corporation consolidated financial statements included elsewhere herein for additional information.

As of March 5, 2008, we held $6.3 million of investment grade securities with an auction reset feature (“auction rate securities”). Our auction rate securities consist of securities issued by closed-end investment companies with portfolio asset coverage of at least 200%, and auction rate investments backed by student loans, issued under programs such as the Federal Family Education Loan Program, all of which had credit ratings of AAA when purchased.  The Dutch auction process that resets the applicable interest rate at predetermined calendar intervals is intended to provide liquidity to the holder of auction rate securities by matching buyers and sellers within a market context enabling the holder to gain immediate liquidity by selling such interests at par or rolling over their investment. If there is an imbalance between buyers and sellers the risk of a failed auction exists.

We have not experienced a failed auction for any of our securities as of December 31, 2007.  However, we did experience failed auctions with certain of our issues in February 2008.  Given the deteriorating credit markets, and the increased incidence of failure within the auction market in February 2008, there can be no assurance as to when we would be able to liquidate a particular issue. In such case of a failure, the auction rate securities continue to pay interest in accordance with their terms, however, we may not be able to executeaccess the par value of the invested funds until a future auction of these investments is successful, the security is called by the issuer or a buyer is found outside of the auction process.  Furthermore, if this situation were to persist despite our business plansability to hold such investments until maturity, we may be required to record an impairment charge in a future period.

Management believes that the fair value of our investments in auction rate securities continue to approximate  their par value and that the underlying credit quality of the assets backing its auction rate securities investments have not been impacted by the reduced liquidity of these investments subsequent to December 31, 2007.  We will continue to monitor and evaluate our business may suffer.investments in auction rate securities for any further reduction in liquidity and potential impairment in future periods.  See the CombiMatrix group and the Acacia Technologies group discussion and analysisNote 2 of our Notes to Consolidated Financial Statements for additional factors impacting the adequacy ofdetails about our available funds.

Refer to Note 2 to the Acacia Research Corporation consolidated financial statements included elsewhere herein. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Our exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in the general level of United States interest rates, particularly because a significant portion of our investments are in short-term debt securities issued by the U.S. government, U.S. corporations, institutional money market funds and other money market instruments. The primary objective of our investment activities is to preserve principal while at the same time maximizing the income received without significantly increasing risk. To minimize risk, we maintain a portfolio of cash, cash equivalents and short-term investments in a variety of investment-grade securities and with a variety of issuers, including corporate notes, commercial paper and money market instruments. Due to the nature of our short-term investments, we believe that we are not subject to any material market risk exposure. We do not have any derivative financial instruments. 43 DISCUSSION OF SEGMENTS' OPERATIONS, FINANCIAL RESOURCES AND LIQUIDITY COMBIMATRIX GROUP MANAGEMENT'S DISCUSSION AND ANALYSIS (A DIVISION OF ACACIA RESEARCH CORPORATION) YOU SHOULD READ THIS DISCUSSION IN CONJUNCTION WITH THE COMBIMATRIX GROUP, A DIVISION OF ACACIA RESEARCH CORPORATION, FINANCIAL STATEMENTS AND RELATED NOTES AND THE ACACIA RESEARCH CORPORATION CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES, BOTH INCLUDED ELSEWHERE HEREIN.

Item 1. "Business," for a general overview of the CombiMatrix group's business. Although AR-CombiMatrix stock is intended to reflect the separate performance of the CombiMatrix group, rather than the performance of Acacia Research Corporation as a whole, the CombiMatrix group is not a separate legal entity. Holders of AR-CombiMatrix stock are stockholders of Acacia Research Corporation. As a result, they continue to be subject to all of the risks of an investment in Acacia Research Corporation and all of its businesses, assets and liabilities. The assets Acacia Research Corporation attributes to the CombiMatrix group could be subject to the liabilities of the Acacia Technologies group.

RESEARCH AND DEVELOPMENT CONTRACT. In March 2004, the CombiMatrix group completed all phases of its research and development agreement with Roche. As a result of completing all obligations under this agreement and in accordance with the CombiMatrix group's revenue recognition policies for multiple-element arrangements, the CombiMatrix group recognized $17.3 million of research and development contract revenues during the first quarter of 2004, all of which were previously deferred. The majority of research and development efforts under the Roche agreement were incurred prior to 2004. GOVERNMENT CONTRACT AND COST OF GOVERNMENT CONTRACT REVENUES. In March 2004, the CombiMatrix group executed a two-year $5.9 million research and development contract with the Department of Defense to further the development of the CombiMatrix group's array technology for the detection of biological threat agents. Under the terms of the contract, the CombiMatrix group is reimbursed on a periodic basis for actual costs incurred to perform its obligations, plus a fixed fee. Revenues are recognized under the percentage-of-completion method of accounting, using the cost-to-cost approach to measure completeness at the end of each reporting period. Cost of government contract revenues reflect research and development expenses incurred in connection with the CombiMatrix group's commitments under its biowarfare detection contract with the Department of Defense, which was approximately 34% complete as of December 31, 2004. Based on actual costs incurred through December 31, 2004, the CombiMatrix group expects to incur approximately $2.2 million and $819,000 in research and development costs during 2005 and 2006, respectively, to complete its obligations to the Department of Defense under this contract. 44 Government contract revenues in 2002 included amounts earned from the CombiMatrix group's performance under its Phase I SBIR Department of Defense contract, Phase I NIH grant and one-time contract research and development revenues. The SBIR Department of Defense and NIH grants were completed during the third quarter of 2002. SERVICE CONTRACTS. Service contract revenues include maintenance and service contract fees recognized by CombiMatrix K.K. from existing array customers in Japan. As of December 31, 2004, the terms of these contracts had expired. PRODUCT REVENUES AND COST OF PRODUCT SALES. Product revenues and costs of product sales during 2004 relate to domestic and international sales of the CombiMatrix group's array products. The CombiMatrix group launched its CustomArray(TM) DNA array platform in March 2004 and its CustomArray(TM) 12K DNA expression array in July 2004. Product revenues and cost of product sales during 2003 and 2002 were recognized by CombiMatrix K.K. from sales of DNA array synthesizers and related array products and services to Japanese research institutions. RESEARCH AND DEVELOPMENT EXPENSES (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Research and development expenses ................. $ 5,294 $ 8,098 $ 18,187 Charge for acquired in-process research and development .......................... - - 17,237
RESEARCH AND DEVELOPMENT EXPENSES. The decrease in research and development expenses in 2004, as compared to 2003 and 2002, was primarily due to the CombiMatrix group's completion of several Roche related research and development projects during the third and fourth quarters of 2003, and final completion of the research and development agreement with Roche in the first quarter of 2004. During 2003 and 2002, the CombiMatrix group's research and development activities were driven primarily by ongoing performance obligations under the product commercialization phase of its license and research and development agreements with Roche. These activities include costs associated with direct labor, supplies and materials, development of prototype arrays and instruments and the use of outside consultants for certain engineering efforts. With the completion of the research and development agreement with Roche, year-to-date and future research and development expenses were and will continue to be incurred in connection with the CombiMatrix group's commitments under its collaboration and supply agreements with various strategic partners including Furuno and Toppan, as well as ongoing internal research and development efforts in the areas of genomics, drug discovery and development and material sciences. The CombiMatrix group expects its research and development expenses to continue to be volatile and such expenses could increase in future periods as additional contract and/or internal research and development agreements are undertaken. CHARGE FOR ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT. Operating expenses in 2002 include a non-cash charge for acquired in-process research and development of $17.2 million, related to Acacia Research Corporation's purchase of the stockholder interests in CombiMatrix Corporation that we did not already own. MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES AND LEGAL SETTLEMENT CHARGES (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Marketing, general and administrative expenses .... $ 9,377 $ 8,714 $ 10,334 Legal settlement charges .......................... 812 144 18,471
MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES. The increase in 2004, as compared to 2003, was due primarily to an increase in corporate professional fees related to the CombiMatrix group's Sarbanes-Oxley compliance projects of approximately $303,000 and an increase in marketing and sales costs of approximately $447,000 related to the launch of the CombiMatrix group's CustomArray(TM) DNA array platform beginning in March 2004 and overall expansion of the CombiMatrix group's sales and marketing division. The decrease in 2003, as compared to 2002, was due primarily to a decrease in the CombiMatrix group's corporate legal expenses of approximately $827,000, primarily related to the settlement of litigation with Nanogen, a decrease in legal, accounting and other professional fees of approximately $704,000 related to Acacia Research Corporation's recapitalization and merger transactions completed in December 2002 and a decrease in overhead of approximately $383,000 related primarily to reduced general marketing and sales and administrative personnel. This decrease was partially offset by an increase in the CombiMatrix group's rent and utilities expenses of approximately $473,000 as a result of the increase in occupancy of its corporate headquarters in Mukilteo, Washington during 2003. 45 Included in marketing, general and administrative expenses are allocated corporate charges of $689,000 in 2004, $894,000 in 2003 and $1.2 million in 2002. See "Critical Accounting Policies" for a description of the management allocation policies implemented. LEGAL SETTLEMENT CHARGES. In 2002, in connection with the September 2002 settlement agreement between CombiMatrix Corporation, Dr. Donald Montgomery, and Nanogen the CombiMatrix group expensed a $1.0 million payment to Nanogen and recorded a non-cash charge in the amount of $17.5 million related to the fair value of CombiMatrix Corporation common shares issued to Nanogen. In addition, the CombiMatrix group recorded a net non-cash charge totaling $812,000 during 2004, which reflects the fair value of AR-CombiMatrix common stock issued and potentially issuable to Nanogen, Inc. during the period in connection with certain anti-dilution provisions of the settlement agreement. Periodic charges and the related liability are estimated based on the number of shares issuable and or potentially issuable and the AR-CombiMatrix stock price at the end of the respective reporting period. The anti-dilution provisions of the settlement agreement expire in September 2005. NON-CASH STOCK COMPENSATION AMORTIZATION (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Non-cash stock compensation amortization: Research and development .......................... $ 91 $ 466 $ 1,868 Marketing, general and administrative ............. 663 1,189 4,540
The decrease was primarily due to the accelerated method of stock compensation amortization utilized which results in higher amounts of amortization in the earlier vesting periods and the impact of non-cash stock compensation expense reversals related to the forfeiture of certain unvested stock options during the respective periods. Non-cash stock compensation expense reversals totaled $185,000 in 2004 and $1.2 million in both 2003 and 2002. Non-cash deferred stock compensation amounts were fully amortized as of December 31, 2004. MINORITY INTERESTS (IN THOUSANDS) 2004 2003 2002 ----------- ----------- ----------- Minority interests ................................ $ - $ 30 $ 23,702
The decrease was primarily due to Acacia Research Corporation's acquisition of the remaining ownership interests in CombiMatrix Corporation in December 2002 and CombiMatrix K.K. in July 2003. Acacia Research Corporation's interests in CombiMatrix K.K. have been attributed to the CombiMatrix group. INFLATION Inflation has not had a significant impact on the CombiMatrix group in the current or prior periods. LIQUIDITY AND CAPITAL RESOURCES At December 31, 2004, cash and cash equivalents and short-term investments totaled $23.7 million, compared to $17.3 million at December 31, 2003. Working capital at December 31, 2004 was $22.1 million, compared to a working capital deficit at December 31, 2003 of $1.6 million. At December 31, 2003 working capital included $17.6 million in deferred revenues primarily related to the CombiMatrix group's agreements with Roche and Toppan, which are not subject to any refund or repayment obligations and do not represent payment obligations of the CombiMatrix group. Working capital increased in 2004 due primarily to the recognition of $17.3 million in Roche related deferred contract revenues in the first quarter of 2004 and the impact of net cash flow activities as discussed below. The change in cash and cash equivalents for the years ended December 31, 2004, 2003 and 2002 was comprised of the following (in thousands): 46 FOR THE YEARS ENDED DECEMBER 31, ----------------------------------------- 2004 2003 2002 ----------- ----------- ----------- Net cash provided by (used in) continuing operations: Operating activities ................................... $ (11,584) $ (3,910) $ (16,142) Investing activities ...................................

(17) (13) 92 ----------- ----------- ----------- (Decrease) increase in cash and cash equivalents ......... $ (822) $ 516 $ (9,301) =========== =========== ===========
The increase in net cash outflows from operations for the CombiMatrix group in 2004, compared to 2003, was primarily due to a decrease in operating cash receipts from customers, which totaled $3.0 million in 2004, comprised of $1.7 million from the Department of Defense, $1.0 million from Furuno and $265,000 from the sale of array products and related services, compared to $12.8 million in the comparable 2003 period, consisting primarily of $9.8 million related to the completion of certain milestones and delivery of prototype products and services pursuant to its agreements with Roche and an up-front payment of $1.0 million and a $1.4 million milestone payment pursuant to its agreement with Toppan. The decrease in payments from customers was partially offset by the decrease in operating expenses and the impact of the timing of the receipt of payments from customers and payments to vendors. The decrease in net cash outflows from operations in 2003, as compared to 2002, was primarily attributable to the reduction in research and development expenses incurred by the CombiMatrix group and the decrease in marketing, general and administrative expenses as discussed above. The change was also due to an increase in operating cash receipts during 2003, from Roche and Toppan, as discussed above. Toppan related cash payments are included in deferred revenues at December 31, 2004 and 2003. In 2002, the CombiMatrix group's negative cash flows from operations was due primarily to the continued expansion of the group's research and development activities including its efforts under its Roche and NASA agreements executed in 2001. Losses from operations in 2002 were partially offset by the receipt of milestone and advance payments of $11.6 million primarily from Roche. The change in net cash flows used in investing activities was due primarily to the CombiMatrix group's ongoing short term cash management activities and changes in short term investments in connection with certain financing activities discussed below. Fixed asset purchases were $810,000, $83,000 and $1.0 million in 2004, 2003 and 2002, respectively. The change in net cash inflows attributed to the CombiMatrix group from financing activities in 2004, compared to 2003, was due to the completion of an equity financing which raised net proceeds of approximately $13.7 million through the sale of Acacia Research - CombiMatrix common stock during 2004, compared to equity financing net proceeds of $4.9 million during the comparable 2003 period. Financing activities in 2004 also included proceeds from the exercise of Acacia Research - CombiMatrix common stock warrants and stock options, totaling $5.1 million, compared to $1.0 million in the comparable 2003 period. Cash used in financing activities in 2002 was comprised primarily of payments on the CombiMatrix group's capital lease obligation totaling $2.8 million (the capital lease obligation was paid in full in November 2002), which were partially offset by proceeds from stock option exercises of $106,000. To date, the CombiMatrix group has relied primarily upon selling equity securities as well as payments from strategic partners to generate the funds needed to finance the implementation of the CombiMatrix group's business strategies. The CombiMatrix group cannot assure that it will not encounter unforeseen difficulties that may deplete capital resources more rapidly than anticipated. Any efforts to seek additional funds could be made through equity, debt or other external financings, however the CombiMatrix group cannot assure that additional funding will be available on favorable terms, if at all. If the CombiMatrix group fails to obtain additional funding when needed, the CombiMatrix group may not be able to execute its business strategies and its business may suffer. The CombiMatrix group's long-term capital requirements will be substantial and the adequacy of its available funds will depend upon many factors, including: o the costs of commercialization activities, including sales and marketing, manufacturing and capital equipment; o the CombiMatrix group's continued progress in research and development programs; o the costs involved in filing, prosecuting, enforcing and defending any patents claims, should they arise; o the CombiMatrix group's ability to license technology; o competing technological developments; o the creation and formation of strategic partnerships; 47 o the costs associated with leasing and improving our headquarters in Mukilteo, Washington; and o other factors that may not be within the CombiMatrix group's control. The CombiMatrix group believes that its cash and cash equivalent and short-term investment balances, anticipated cash flow from operations and other external sources of available credit will be sufficient to meet its cash requirements through at least the next twelve months. However, changes may occur that would cause the CombiMatrix group's available capital resources to be consumed significantly sooner than it currently expects. The CombiMatrix group may be unable to raise sufficient additional capital on favorable terms or at all. If it fails to do so, it may have to curtail or cease operations or enter into agreements requiring it to relinquish rights to certain technologies, products or markets because it will not have the capital necessary to exploit them. OFF-BALANCE SHEET ARRANGEMENTS The CombiMatrix group has not entered into off-balance sheet financing arrangements, other than operating leases. The CombiMatrix group has no significant commitments for capital expenditures in 2005. Other than as set forth below, the CombiMatrix group has no committed lines of credit or other committed funding or long-term debt. The following table lists the CombiMatrix group's material known future cash commitments as of December 31, 2004: PAYMENTS DUE BY PERIOD (IN THOUSANDS) -------------------------------------------------------------- 2009 AND CONTRACTUAL OBLIGATIONS 2005 2006 2007 2008 THEREAFTER ---------- ---------- ---------- ---------- ---------- Operating Leases (2) .......................... $ 1,923 $ 1,836 $ 1,937 $ 1,615 $ - Minimum Royalty Payments(1) ................... 100 100 100 100 1,000 irsiCaixa Foundation research, development, and licensing agreement(4) ................. 125 175 100 - - Leuchemix equity purchases(3) ................. 1,600 2,150 - - - ---------- ---------- ---------- ---------- ---------- Total Contractual Cash Obligations ............ $ 3,748 $ 4,261 $ 2,137 $ 1,715 $ 1,000 ========== ========== ========== ========== ==========

RECENT ACCOUNTING PRONOUNCEMENTS Refer to Note 2 to the Acacia Research Corporation consolidated financial statements included elsewhere herein. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The CombiMatrix group's exposure to market risk is limited to interest income sensitivity, which is affected by changes in the general level of United States interest rates, particularly because the majority of the group's investments are in short-term debt securities issued by the U.S. treasury and by U.S. corporations. The primary objective of the group's investment activities is to preserve principal while at the same time maximizing the income the CombiMatrix group receives without significantly increasing risk. To minimize risk, the CombiMatrix group maintains its portfolio of cash, cash equivalents and short-term investments in a variety of investment-grade securities and with a variety of issuers, including corporate notes, commercial paper, government securities and money market funds. Due to the nature of its short-term investments, the CombiMatrix group believes that it is not subject to any material market risk exposure. At December 31, 2004, the CombiMatrix group had certain assets and liabilities denominated in Japanese Yen as a result of forming CombiMatrix K.K. However, due to the relative insignificance of those amounts, the CombiMatrix group does not believe that it has significant exposure to foreign currency exchange rate risks. The CombiMatrix group currently does not use derivative financial instruments to mitigate this exposure. The CombiMatrix group continues to review this and may begin hedging certain foreign exchange risks through the use of currency forwards or options in future periods. 48 ACACIA TECHNOLOGIES GROUP MANAGEMENT'S DISCUSSION AND ANALYSIS (A DIVISION OF ACACIA RESEARCH CORPORATION) YOU SHOULD READ THIS DISCUSSION IN CONJUNCTION WITH THE ACACIA TECHNOLOGIES GROUP, A DIVISION OF ACACIA RESEARCH CORPORATION, FINANCIAL STATEMENTS AND RELATED NOTES AND THE ACACIA RESEARCH CORPORATION CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES, BOTH INCLUDED ELSEWHERE HEREIN. HISTORICAL RESULTS AND PERCENTAGE RELATIONSHIPS ARE NOT NECESSARILY INDICATIVE OF OPERATING RESULTS FOR ANY FUTURE PERIODS. GENERAL See Item 1. "Business," for a description of the Acacia Technologies group's business. Although the AR-Acacia Technologies stock is intended to reflect the separate performance of the Acacia Technologies group, rather than the performance of Acacia Research Corporation as a whole, the Acacia Technologies group is not a separate legal entity. Holders of the AR-Acacia Technologies stock are stockholders of Acacia Research Corporation. As a result, they continue to be subject to all of the risks of an investment in Acacia Research Corporation and all of Acacia Research Corporation's businesses, assets and liabilities. The assets Acacia Research Corporation attributes to the Acacia Technologies group could be subject to the liabilities of the CombiMatrix group. ACACIA TECHNOLOGIES GROUP (A DIVISION OF ACACIA RESEARCH CORPORATION) RESULTS OF OPERATIONS DIVISION NET LOSS (IN THOUSANDS) 2004 2003 2002 ------------ ------------ ------------ Division net loss .................................... $ (5,543) $ (5,451) $ (12,754)
The changes in net loss were primarily due to operating results and activities as discussed below. REVENUES (IN THOUSANDS) 2004 2003 2002 ------------ ------------ ------------ License fees ......................................... $ 4,284 $ 692 $ 43
LICENSE FEES. License fee revenues are comprised of DMT technology license fees and previously deferred V-chip technology license fees recognized by the Acacia Technologies group. DMT technology license fees were $2.8 million and $692,000 in 2004 and 2003, respectively. The increase was primarily due to the significant growth in the number of DMT technology license agreements executed since March 31, 2003. During 2004, we executed 170 DMT license agreements. License fee revenues will fluctuate from period to period based on the increase in license agreements executed, fluctuations in the sales results or other royalty per unit activities of our licensees that impact the calculation of license fees due, the timing of the receipt of periodic license fee statements and or payments from licensees, and other factors. Periodic license fee revenues may include amounts that relate to prior license periods or prior periods of infringement, which are recognized as revenues in the period received. DMT license fees related to prior periods of infringement for the periods presented above were not significant. Costs incurred in connection with the Acacia Technologies group's ongoing licensing activities are included in marketing, general and administrative expenses and do not expect to receive any additional V-chip related revenues in future periods. License fee revenues for 2004 include $1.5 million in previously deferred V-chip license fees (originally deferred in 2001) recognized as a result of the conclusion of V-chip related litigation in August 2004, as described at Item 3. "Legal Proceedings." We concluded our V-chip licensing program in August 2004. MARKETING, GENERAL AND ADMINISTRATIVE EXPENSE (IN THOUSANDS) 2004 2003 2002 ------------ ------------ ------------ Marketing, general and administrative expenses ....... $ 5,049 $ 4,317 $ 6,883 Legal expenses - patents ............................. 3,133 1,886 1,415
49 MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES. The change in 2004, as compared to 2003, was due primarily to an increase in costs related to the addition of licensing and business development personnel of $418,000, an increase in patent related commercialization costs of $110,000, and an increase in corporate professional fees related to the group's Sarbanes-Oxley compliance projects of $318,000. The decrease in 2003, as compared to 2002, was due primarily to a decrease in legal, accounting and other professional fees related to Acacia Research Corporation's recapitalization and merger transactions completed in December 2002 of $1.3 million, a decrease in overhead related to a reduction in general and administrative personnel of $837,000 and a decrease in general and administrative expenses of $546,000. This decrease was partially offset by an increase in costs related to the Acacia Technologies group's ongoing DMT patent commercialization and enforcement efforts, including increased consulting and engineering costs related to new patent claims, enforcement and the identification of additional potential licensees of our DMT technology of $219,000. LEGAL EXPENSE - PATENTS. Patent related legal expenses in 2004 included $668,000 in deferred V-chip related legal fees recognized as a result of the conclusion of V-chip related litigation in August 2004, as described at Item 3. "Legal Proceedings." The Acacia Technologies group's patent related legal expenses, excluding V-chip related legal fees, increased to $2.5 million during 2004, as compared to $1.9 million, and $1.4 million in the comparable 2003 and 2002 periods, due to an increase in costs incurred in connection with the Acacia Technologies group's ongoing DMT patent commercialization and enforcement programs, including increased legal costs related to new patent claims and the identification of additional potential licensees of our DMT technology and increased patent enforcement costs related to ongoing DMT patent related litigation. See Item 3. "Legal Proceedings" for a description of ongoing DMT related litigation. We expect patent related legal expenses to continue to fluctuate based on actual outside patent counsel fees incurred in connection with the Acacia Technologies group's ongoing DMT and other patent commercialization and enforcement programs. DMT related legal fees to outside attorneys are charged based on actual time and out-of-pocket expenses incurred by external counsel and are not incurred on a contingent fee basis. In connection with the January 2005 acquisition as described above, the Acacia Technologies group acquired 27 additional patent portfolios. Although most litigation with respect to those portfolios is likely to be handled on a contingency basis where attorneys fees are paid out of license fee revenues collected, certain other costs and expenses in connection with the Acacia Technologies group's maintenance, licensing, and enforcement of patents are likely to increase as a result of the acquisition including patent filing fees, patent development costs, travel costs, expert and consulting fees, and other third-party expenses. IMPAIRMENT CHARGES (IN THOUSANDS) 2004 2003 2002 ------------ ------------ ------------ Goodwill impairment charge ........................... $ (1,656) $ - $ - Impairment charge .................................... - (207) (2,748)
GOODWILL IMPAIRMENT CHARGE. In August 2004, as a result of the adverse ruling in the Soundview Technologies litigation described at Item 3. "Legal Proceedings," the Acacia Technologies group recorded a non-cash impairment charge, included in operating expenses, totaling $1.6 million associated with the write-down of 100% of the goodwill related to the V-chip. IMPAIRMENT OF COST METHOD INVESTMENT. In 2003, we recorded an impairment charge of $207,000 for an other-than-temporary decline in the fair value of our cost method investment. Impairment indicators included a continued decline in the working capital of the entity and reference to a recent equity transaction and related valuation indicating an other-than-temporary decline in fair value of the investment. In 2002, we recorded an impairment charge of $2.7 million for an other-than-temporary decline in the fair value of the same cost method investment. Impairment indicators included recurring losses, a decline in working capital and the completion of a recent equity transaction at an amount below our carrying value. AMORTIZATION OF PATENTS (IN THOUSANDS) 2004 2003 2002 ------------ ------------ ------------ Amortization of patents .............................. $ 501 $ 502 $ 1,591
The decrease in 2003, as compared to 2002, was due to a reduction in patent amortization expense due to V-chip technology related patent costs and other intangibles that were fully amortized during 2002. With the acquisition of the assets of Global Patent Holdings, as described above, we expect that a significant portion of the approximated $25.0 million purchase price will be allocated to the patents acquired, which will be amortized over the economic useful lives of the respective patents, resulting in increased amortization charges in 2005 and future periods. See Note 15 to the Acacia Research Corporation consolidated financial statements for additional information. 50 REALIZED AND UNREALIZED GAINS/LOSSES (IN THOUSANDS) 2004 2003 2002 ------------ ------------ ------------ Realized gains (losses) on short-term investments .... - 94 (1,184) Unrealized losses on short-term investments .......... - - (249)
The decrease is due to no investments classified as trading securities held during 2004 and 2003 and the sale of the balance of our trading securities during 2002. INCOME TAXES (IN THOUSANDS) 2004 2003 2002 ------------ ------------ ------------ Benefit for income taxes ............................. 139 137 710
The 2004, 2003 and 2002 income tax benefits primarily reflect the impact of the reversal of deferred tax liabilities related to the amortization of identifiable intangible assets related to certain of Acacia Research Corporation's step acquisitions in 2002, 2001 and 2000. $569,000 of the 2002 income tax benefit also reflects the impact of differences between the 2001 income tax provision and Acacia Research Corporation's final 2001 consolidated tax return filed in September 2002, and is the result of additional deductions against Soundview Technologies taxable income. INFLATION Inflation has not had a significant impact on the Acacia Technologies group in the current or previous periods. LIQUIDITY AND CAPITAL RESOURCES The Acacia Technologies group's cash and cash equivalents and short-term investments totaled $28.6 million at December 31, 2004, compared to $33.2 million at December 31, 2003. Working capital at December 31, 2004 was $27.1 million, compared to $32.7 million at December 31, 2003. The changes in cash and cash equivalents for 2004, 2003 and 2002 were comprised of the following (in thousands): FOR THE YEARS ENDED DECEMBER 31, -------------------------------------------- 2004 2003 2002 ------------ ------------ ------------ Net cash provided by (used in) continuing operations: Operating activities .................................. $ (3,232) $ (5,264) $ (3,519) Investing activities .................................. (180) (5,062) (8,342) Financing activities .................................. (305) (417) (2,048) Net cash used in discontinued operations ................ (925) (907) (908) ------------ ------------ ------------ Increase (decrease) in cash and cash equivalents ........ $ (4,642) $ (11,650) $ (14,817) ============ ============ ============
The change in net cash outflows from operations for the Acacia Technologies group was primarily due to an increase in DMT license fee payments received from licensees which totaled $3.1 million in 2004, compared to $665,000, in the comparable 2003 period, which was partially offset by the increase in marketing, general and administrative expenses as discussed above and the impact of the timing of vendor payments. The increase in net cash outflows from operations in 2003, as compared to 2002, was primarily due to an increase in costs incurred in connection with the launch of the Acacia Technologies group's ongoing DMT patent commercialization and enforcement programs, including increased legal costs related to new patent claims and the identification of additional potential licensees of our DMT technology and the timing of vendor payments, primarily related to professional fees incurred in connection with Acacia Research Corporation's merger and recapitalization transaction completed 2002. The increase in costs was partially offset by payments received from licensees in 2003 totaling $665,000 in connection with the launch of the Acacia Technologies group's DMT licensing program. The change in net cash flows provided by (used in) continuing investing was primarily due to the purchases and sales of short-term investments in connection with the Acacia Technologies group's ongoing short-term cash management activities. 51 Net cash outflows attributed to the Acacia Technologies group from financing activities in 2004, 2003 and 2002 were comprised of corporate and acquisition costs allocated to the CombiMatrix group of $396,000, $620,000 and $1.9 million, respectively, partially offset by AR-Acacia Technologies sock option exercise proceeds of $90,000, $190,000 and $136,000, respectively. In February 2005, Acacia Research Corporation raised gross proceeds of $19,600,000 through the sale of 3,500,000 shares of Acacia Research - Acacia Technologies common stock at a price of $5.60 per share in a registered direct offering. Net proceeds raised of approximately $19,575,000, which are net of related issuance costs, were attributed to the Acacia Technologies group. All of the shares of Acacia Research-Acacia Technologies common stock were offered pursuant to an effective registration statement previously filed with the Securities and Exchange Commission. The Acacia Technologies group believes that its cash and cash equivalent balances, including the proceeds from the February 2005 equity financing described above, anticipated cash flow from operations and other external sources of available credit will be sufficient to meet its cash requirements through at least the next twelve months. To date, the Acacia Technologies group has relied primarily upon selling of Acacia Research Corporation equity securities and payments from our V-chip licensees (primarily in 2001) and DMT licensees (2003 to current) to generate the funds needed to finance the operations of the Acacia Technologies group. As discussed earlier, the V-chip patent expired in July 2003, and the Judge affirmed the ruling of non-infringement as discussed above. In 2003, the Acacia Technologies group began to commercially license its DMT technology recognizing approximately $3.5 million in DMT license fee revenues to date, and intends to acquire and develop additional intellectual property. In July 2004, the Acacia Technologies group acquired U.S. Patent No. 6,226,677 from LodgeNet Entertainment Corporation, which covers technology and methods for redirecting users to a login page when accessing the Internet, and launched its licensing and enforcement program for this patent in the third quarter of 2004. Acacia Global Acquisition Corporation's acquisition of the assets of Global Patent Holdings, LLC as discussed above, provides the Acacia Technologies group with ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts, and cover technologies used in a wide variety of industries. The acquisitions expand and diversify the Acacia Technologies group's revenue generating opportunities. However, there can be no assurance that the Acacia Technologies group will be able to implement its future plans. Failure by management to achieve its plans would have a material adverse effect on the Acacia Technologies group and on Acacia Research Corporation's ability to achieve its intended business objectives. The Acacia Technologies group's success also depends on its ability to protect its intellectual property. The timing of the receipt of revenues by the Acacia Technologies group's business operations are subject to certain risks and uncertainties, including: o market acceptance of our technologies and services; o business activities and financial results of our licensees; o technological advances that may make our technologies obsolete or less competitive; o increases in operating costs, including costs for legal services, engineering and research and personnel; o the availability and cost of capital; o general economic conditions; and o governmental regulation that may restrict the Acacia Technologies group's business. OFF-BALANCE SHEET ARRANGEMENTS The Acacia Technologies group has not entered into off-balance sheet financing arrangements, other than operating leases. The Acacia Technologies group has no significant commitments for capital expenditures in 2005. Other than as set forth below, the Acacia Technologies group has no committed lines of credit or other committed funding or long-term debt. The following table lists the Acacia Technologies group's material known future cash commitments as of December 31, 2004, and material known commitments arising from events subsequent to year end: PAYMENTS DUE BY PERIOD (IN THOUSANDS) -------------------------------------------------------------- 2009 AND CONTRACTUAL OBLIGATIONS 2005 2006 2007 2008 THEREAFTER ---------- ---------- ---------- ---------- ---------- Operating Leases (1) .......................... $ 348 $ 390 $ 49 $ - $ - Consulting contract (2) ....................... 974 1,074 99 - - ---------- ---------- ---------- ---------- ---------- Total Contractual Cash Obligations ............ $ 1,322 $ 1,464 $ 148 $ - $ - ========== ========== ========== ========== ==========
52 - ------------- (1) Excludes any allocated rent expense in connection with Acacia Research Corporation's management allocation policies. (2) Reflects $2.0 million consulting contract commitment, including reimbursable expenses, to be paid over two years in connection with the Acacia Technologies group's purchase of the assets of Global Patent Holdings, LLC in January 2005, as described above. In connection with the purchase of the outstanding ownership interests in Acacia Media Technologies in November 2001, Acacia Media Technologies also executed related assignment agreements which granted to the former owners of Acacia Media Technologies' current patent portfolio the right to receive a royalty of 15% of future net revenues, as defined in the agreements, generated by Acacia Media Technologies' current patent portfolio, which includes its DMT patents. No royalty obligation has been incurred as of December 31, 2004. Any royalties paid pursuant to the agreements will be expensed in the statement of operations. RECENT ACCOUNTING PRONOUNCEMENTS Refer to Note 2 to the Acacia Research Corporation consolidated financial statements included elsewhere herein. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The Acacia Technologies group's exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in the general level of United States interest rates, particularly because a significant portion of our investments are in short-term debt securities issued by United States corporations, institutional money market funds and other money market instruments. The primary objective of our investment activities is to preserve principal while at the same time maximizing the income received without significantly increasing risk. To minimize risk, we maintain a portfolio of cash, cash equivalents and short-term investments in a variety of investment-grade securities and with a variety of issuers, including U.S. government and corporate notes and bonds, commercial paper and money market instruments. Due to the nature of our short-term investments, we believe that we are not subject to any material market risk exposure. We do not have any derivative financial instruments. RISK FACTORS An investment in our stock involves a number of risks. Before making a decision to purchase our securities, you should carefully consider all of the risks described in this annual report. If any of the risks incorporated by reference into this annual report actually occur, our business, financial condition and results of operations could be materially adversely affected. If this were to occur, the trading price of our securities could decline significantly and you may lose all or part of your investment. You should carefully review the "Risk Factors" set forth on pages 3 through 21 of our Form S-3 Registration Statement filed on February 1, 2005, incorporated herein by reference. ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Refer to the caption "Quantitative and Qualitative Disclosures About Market Risk" for Acacia Research Corporation, the CombiMatrix group and the Acacia Technologies group under Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations."

The primary objective of our investment activities is to preserve principal while concurrently maximizing the income we receive from our investments without significantly increasing risk. Some of the securities that we may invest in may be subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the current value of the principal amount of our investment will decline. To minimize this risk in the future, we intend to maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, money market funds, high-grade corporate bonds, government and non-government debt securities and certificates of deposit. In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate. As of December 31, 2004,2007, all of our investments were in money market funds, high-grade corporate bonds, auction rate securities, certificates of deposit and U.S. government debt securities. A hypothetical 100 basis point increase in interest rates would not have a material impact on the fair value of our available-for-sale securities as of December 31, 2004.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders of
Acacia Research Corporation
We have audited Acacia Research Corporation’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Acacia Research Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on Acacia Research Corporation’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on page 56the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, Acacia Research Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by COSO.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Acacia Research Corporation as of December 31, 2007 and the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the year then ended and our report dated March 12, 2008, expressed an unqualified opinion on these financial statements.

The CombiMatrix group is seeking to become a broadly diversified biotechnology company, through the development of proprietary technologies and products in the areas of drug development, genetic analysis, nanotechnology research, defense and homeland security markets, as well as other potential markets where its products could be utilized. Among the technologies being developed by the CombiMatrix group are a platform technology to rapidly produce customizable arrays, which are semiconductor-based tools for use in identifying and determining the roles of genes, gene mutations and proteins. This technology has a wide range of potential applications in the areas of genomics, proteomics, biosensors, drug discovery, drug development, diagnostics, combinatorial chemistry, material sciences and nanotechnology. Other technologies include proprietary molecular synthesis and screening methods for the discovery of potential new drugs. CombiMatrix K.K., a wholly owned Japanese corporation located in Tokyo, is exploring opportunities for CombiMatrix Corporation's array system with pharmaceutical and biotechnology companies in the Asian market. Our intellectual property licensing business, referred to as the "the Acacia Technologies group," is primarily comprised of our interests in three wholly owned subsidiaries: (1) Acacia Media Technologies Corporation, ("Acacia Media Technologies") a Delaware corporation, (2) Soundview Technologies, Inc., ("Soundview Technologies") a Delaware corporation, and (3) Acacia Internet Access Corporation, a Delaware corporation, and also includes all corporate assets, liabilities, and related transactions of Acacia Research Corporation, attributedand its wholly owned operating subsidiaries.  As used herein, “we,” “us” and “our” refer to the Acacia Research Corporation'sCorporation and/or its wholly owned operating subsidiaries.  All intellectual property acquisition, development, licensing business. Theand enforcement activities are conducted solely by certain of Acacia Technologies group develops, acquires,Research Corporation’s wholly owned operating subsidiaries.

Acacia Research Corporation’s operating subsidiaries acquire, develop, license and licensesenforce patented technologies.  IncludingOur operating subsidiaries generate license fee revenues and related cash flows from the impactgranting of licenses for the January 28, 2005 acquisitionuse of patented technologies that our operating subsidiaries own or control.  Our operating subsidiaries assist patent owners with the assetsprosecution and development of Global Patent Holdings, LLC ("Global Patent Holdings") discussed at Note 15,their patent portfolios, the Acacia Technologies group controls 29protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, if necessary, with the enforcement against unauthorized users of their patented technologies. Currently, on a consolidated basis, our operating subsidiaries own or control the rights to 91 patent portfolios, which include 126 U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries including audio/video-on-demand, digital ad insertion, interactive television, broadcast equipment, data transmission, cache coherency, data file synchronization, data matrix bar codes, dynamic manufacturing models, product activation, encryption, image resolutionindustries.

CombiMatrix Group Split-off Transaction and enhancement, scheduling software, interstitial Internet advertising, interactive simulation systems, peerRelated Discontinued Operations.  In January 2006, Acacia Research Corporation’s board of directors approved a plan for its wholly owned subsidiary, CombiMatrix Corporation, the primary component of Acacia Research Corporation’s CombiMatrix group, to peer network communications, spreadsheet programs, endoscopic cameras, video noise reduction,become an independent public company.  CombiMatrix Corporation’s registration statement on Form S-1 was declared effective by the Securities and audio/video synchronization. Exchange Commission (“SEC”) on June 8, 2007.  Following the redemption period required by Acacia Research Corporation’s Restated Certificate of Incorporation, on August 15, 2007 (the “Redemption Date”), CombiMatrix Corporation was split-off from Acacia Research Corporation through the redemption of all outstanding shares of Acacia Research-CombiMatrix common stock in exchange for the distribution of new shares of CombiMatrix Corporation common stock, on a pro-rata basis, to the holders of Acacia Research-CombiMatrix common stock on the Redemption Date (the “Split-off Transaction”). On the Redemption Date, every ten (10) shares of Acacia Research-CombiMatrix common stock outstanding on August 15, 2007, was redeemed for one (1) share of common stock of CombiMatrix Corporation.  Subsequent to the Redemption Date, Acacia Research Corporation no longer owns any equity interests in CombiMatrix Corporation and the two companies operate independently of each other.

As a result of the Split-off Transaction, we have disposed of our investment in CombiMatrix Corporation.  Refer to Note 10A for information regarding presentation of the assets, liabilities, results of operations and cash flows for the CombiMatrix group as discontinued operations in the accompanying consolidated financial statements for all periods presented, in accordance with guidance set forth in SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”).

Capital Structure. As a result of the Split-off Transaction, the CombiMatrix group is no longer a business group of Acacia Research Corporation.  Pursuant to the Split-off Transaction, all outstanding shares of Acacia Research-CombiMatrix common stock were redeemed, and hence, all rights of holders of Acacia Research-CombiMatrix common stock ceased as of the Redemption Date, except for the right, upon the surrender to the exchange agent of shares of Acacia Research-CombiMatrix common stock, to receive new shares of CombiMatrix Corporation stock pursuant to the exchange ratio described above.  Subsequent to the consummation of the Split-off Transaction, Acacia Research Corporation’s only class of common stock outstanding is its Acacia Research-Acacia Technologies common stock.

Prior to the Split-off Transaction, Acacia Research Corporation had two classes of common stock outstanding, its Acacia Research-Acacia Technologies common stock (“AR-Acacia Technologies stock”) and its Acacia Research-CombiMatrix common stock ("AR-CombiMatrix stock").  AR-Acacia Technologies stock was intended to reflect separately the performance of Acacia Research Corporation’s Acacia Technologies group.  AR-CombiMatrix stock was intended to reflect separately the performance of Acacia Research Corporation’s CombiMatrix group.  Although the AR-Acacia Technologies stock and the AR-CombiMatrix stock were intended to reflect the performance of our different business groups, they were both classes of common stock of Acacia Research Corporation and were not stock issued by the respective groups.
We were incorporated on January 25, 1993 under the laws of the State of California. In December 1999, we changed our state of incorporation from California to Delaware. LIQUIDITY AND RISKS To date, we

·market acceptance of our operating subsidiaries’ patented technologies and continues to develop its commercial products. To date, the CombiMatrix group has relied primarily upon selling equity securities, as well as payments from strategic partners to generate the funds needed to finance the implementation of the CombiMatrix group's business strategies. The CombiMatrix group has historically been substantially dependent on its arrangements with strategic partners including Roche Diagnostics GmbH ("Roche"), and has relied upon payments by Roche and other partners for a majority of its future revenues. The CombiMatrix group intends to enter into additional strategic partnerships to develop and commercialize future products. However, there can be no assurance that the CombiMatrix group will be able to implement its future plans. Failure by management to achieve its plans would have a material adverse effect on the CombiMatrix group's and services;

·technological advances that may make our patented technologies obsolete or less competitive;
·increases in operating costs, including costs for legal services, engineering and research and personnel;
·the availability and cost of capital; and
·governmental regulation that may restrict Acacia Research Corporation’s business.

Acacia Research Corporation's ability to achieve its intended business objectives. The CombiMatrix group'sCorporation’s success also depends on its operating subsidiaries’ ability to protect itstheir intellectual property.  In addition, the CombiMatrix group cannot assure that it will not encounter unforeseen difficulties that may deplete capital resources more rapidly than anticipated. Any efforts to seek additional funds could be made through equity, debt or other external financings; however, the CombiMatrix group cannot assure that additional funding will be availableOur operating subsidiaries rely on favorable terms, if at all. If the CombiMatrix group fails to obtain additional funding when needed, the CombiMatrix group may not be able to execute its business strategies and its business may suffer. The CombiMatrix group's business depends on issued and pending patents, and the loss of any patents or the group's failure to secure the issuance of patents covering elements of its business processes would materially harm its business and financial condition. The patents covering the CombiMatrix group's core technology begin to expire January 5, 2018. To date, the Acacia Technologies group has relied primarily upon selling of Acacia Research Corporation equity securities and payments from our V-chip licensees (primarily in 2001) and Digital Media Transmission ("DMT(R)") licensees (2003 to current) to generate the funds needed to finance the operations of the Acacia Technologies group. The V-chip patent expired in July 2003. The V-chip licensing program was concluded in August 2004 and we do not expect to collect any additional V-chip related license fee revenues in future periods. The Acacia Technologies group began to commercially license its DMT technology in 2003, recognizing approximately $3.5 million in DMT license fee revenues to date, and intends to acquire and develop additional intellectual property. Acacia Global Acquisition Corporation's acquisition of the assets of Global Patent Holdings, LLC as discussed at Note 15, provides the Acacia Technologies group with ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts, and cover technologies used in a wide variety of industries. The acquisition expands and diversifies the Acacia Technologies group's revenue generating opportunities. However, there can be no assurance that the Acacia Technologies group will be able to implement its future plans. Failure by management to achieve its plans would have a material adverse effect on the Acacia Technologies group and on Acacia Research Corporation's ability to achieve its intended business objectives. The Acacia Technologies group's success also depends on its ability to protect its intellectual property. The Acacia Technologies group relies on itstheir proprietary rights and their protection.  Although reasonable efforts will be taken to protect the Acacia Technologies group'sour operating subsidiaries’ proprietary rights, the complexity of international trade secret, copyright, trademark and patent law, and common law, coupled with limited resources and the demands of quick delivery of technologies to market, create risk that these efforts will prove inadequate.  Accordingly, if weour operating subsidiaries are unsuccessful with litigation to protect ourtheir intellectual property rights, the future consolidated revenues of the Acacia Technologies groupResearch Corporation could be adversely affected. The Acacia Technologies group's U.S. DMT patents expire in 2011 and its foreign DMT patents expire in 2012. F-7 RECAPITALIZATION TRANSACTION On December 11, 2002, our stockholders voted in favor of a recapitalization transaction, which became effective on December 13, 2002, whereby we created two new classes of common stock called Acacia Research-CombiMatrix stock ("AR-CombiMatrix stock") and Acacia Research-Acacia Technologies stock ("AR-Acacia Technologies stock"), and divided our existing Acacia Research Corporation common stock into shares of the two new classes of common stock. AR-CombiMatrix stock is intended to reflect separately the performance of Acacia Research Corporation's CombiMatrix group. AR-Acacia Technologies stock is intended to reflect separately the performance of Acacia Research Corporation's Acacia Technologies group. Although the AR-CombiMatrix stock and the AR-Acacia Technologies stock are intended to reflect the performance of our different business groups, they are both classes of common stock of Acacia Research Corporation and are not stock issued by the respective groups. All share and per share information in the consolidated financial statements and accompanying notes to the consolidated financial statements, unless otherwise noted, give effect to the recapitalization as of January 1, 2002.


2.             SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ACCOUNTING PRINCIPLES AND FISCAL YEAR END.

Accounting Principles and Fiscal Year End.  The consolidated financial statements and accompanying notes are prepared on the accrual basis of accounting in accordance with generally accepted accounting principles in the United States of America.  We have a December 31 year end. PRINCIPLES OF CONSOLIDATION.

Principles of Consolidation.  The accompanying consolidated financial statements include the accounts of Acacia Research Corporation and its wholly owned and majority-owned subsidiaries. Investments for which Acacia Research Corporation possesses the power to direct or cause the direction of the management and policies, either through majority ownership or other means, are accounted for under the consolidation method.  Material intercompany transactions and balances have been eliminated in consolidation. Investments in companies in which we maintain an ownership interest of 20% to 50% or exercise significant influence over operating and financial policies are accounted for under the equity method. The cost method is used where we maintain ownership interests of less than 20% and do not exercise significant influence over the investee. REVISION IN THE CLASSIFICATION OF CERTAIN SECURITIES. In connection with the preparation of this report, we concluded that it was appropriate to classify our auction rate municipal bonds and variable rate municipal demand notes as current investments. Previously, such investments had been classified as cash and cash equivalents. Accordingly, we have revised our prior classification to report these securities as current investments in our Consolidated Balance Sheet as of December 31, 2003. We have also made corresponding adjustments to our Consolidated Statement of Cash Flows for the year ended December 31, 2002, to reflect the gross purchases and sales of these securities as investing activities rather than as a component of cash and cash equivalents. This change in classification does not affect previously reported cash flows from operations or from financing activities in our previously reported Consolidated Statements of Cash Flows, or our previously reported Consolidated Statements of Income for any period. As of December 31, 2003, before this revision in classification, $7,750,000 of these current investments were classified as cash and cash equivalents on our Consolidated Balance Sheet. For the fiscal year ended December 31, 2002, before this revision in classification, net cash used in investing activities related to these current investments of $7,750,000 were included in cash and cash equivalents in our Consolidated Statement of Cash Flows. REVENUE RECOGNITION.

Revenue Recognition.  We recognize revenue in accordance with Staff Accounting Bulletin No. 104, "Revenue Recognition" ("“Revenue Recognition” (“SAB No. 104"104”) and related authoritative pronouncements. Revenues from multiple-element arrangements are accounted for in accordance with Emerging Issues Task Force ("EITF") Issue 00-21, "Revenue Arrangements with Multiple Deliverables."  Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been substantially performed pursuant to the terms of the license agreement, (iii) amounts are fixed or determinable and (iv) collectibility of amounts is reasonably assured. F-8 COMBIMATRIX GROUP Revenues from multiple-element arrangements involving license fees, up-front payments and milestone payments, which are received and/or billable by us in connection with other rights and services that represent continuing obligations of ours, are deferred until all of the elements have been delivered or until we have established objective and verifiable evidence of the fair value of the undelivered elements. Revenues from government grants and contracts are recognized in accordance with Accounting Research Bulletin ("ARB") No. 43, "Government Contracts," and related pronouncements. Accordingly, revenues are recognized under the percentage-of-completion method of accounting, using the cost-to-cost approach to measure completeness at each reporting period. Under the percentage-of-completion method of accounting, contract revenues and expenses are recognized in the period that work is performed based on the percentage of actual incurred costs to estimated total contract costs. Actual contract costs and cost estimates include direct charges for labor and materials and indirect charges for labor, overhead and certain general and administrative charges. Contract change orders and claims are included when they can be reliably estimated and are considered probable. For contracts that extend over a one-year period, revisions in contract cost estimates, if they occur, have the effect of adjusting current period earnings applicable to performance in prior periods. Should current contract estimates indicate an overall future loss to be incurred, a provision is made for the total anticipated loss in the current period. Revenue from the sale of products and services, including shipping and handling fees, are recognized when delivery has occurred or services have been rendered. Deferred revenues arise from payments received in advance of the culmination of the earnings process. Deferred revenues expected to be recognized within the next twelve months are classified within current liabilities. Deferred revenues will be recognized as revenue in future periods when the applicable revenue recognition criteria as described above are met.

Revenue

Revenues generated from license agreements are generally accrued and recognized as revenue in the period earned, provided that amounts are fixed or determinable and collectibility is reasonably assured.

Certain license agreements provide for the payment of contractually determined paid-up license fees in consideration for the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by our operating subsidiaries.  Certain of the agreements also provide for future royalties or additional required payments based on future activities.  Generally, the execution of these license agreements also provide for the release of the licensee from certain claims and the dismissal of any pending litigation.  Pursuant to the terms of these agreements, our operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future license and related releases, including no express or implied obligation on our operating subsidiaries’ part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the license and releases upon execution of the agreement.  As such, the earnings process is complete upon the execution of the agreement, and revenue is recognized upon execution of the agreement, when collectibility is reasonably assured, and all other revenue recognition criteria have been met.  Refer to Note 12 for information on inventor royalties and contingent legal fees.

Certain license agreements provide for the calculation of license fees based on a licensee'slicensee’s actual quarterly sales or actual per unit activity, applied to a contractual royalty rate.  Licensees that pay license fees on a quarterly basis generally report actual quarterly sales or actual per unit activity information and related quarterly license fees due to the Acacia Technologies group within 30 to 45 days after the end of the quarter in which such sales or activity takes place.  The amount of license fees due under these license agreements each quarter cannot be reasonably estimated by management.  Consequently, the Acacia Technologies group recognizesour operating subsidiaries recognize revenue from these licensing agreements on a three-month lag basis, in the quarter following the quarter of sales or per unit activity, provided amounts are fixed or determinable and collectibility is reasonably assured. The lag method described above allows for the receipt of licensee royalty reports prior to the recognition of revenue.

Certain license agreements provide for the payment of a minimum upfront annual license fee at the inception of each annual license term.  Minimum upfront annual license fees are generally determined based on a licensee'slicensee’s estimated annual sales or a licensee'slicensee’s base level of per unit activity.  These minimum upfront annual license fee payments are deferred and amortized to revenue on a straight-line basis over the annual license term.  To the extent actual annual royalties, determined and reported in accordance with the terms of the respective agreements, exceed the minimum upfront annual license fees paid, the additional royalties are recognized in revenue in the quarter following the quarter in which the base per unit activity was exceeded or the quarter following the annual license term, depending on the terms of the respective agreement, provided that amounts are fixed or determinable and collectibility is reasonably assured.  F-9 Amounts of additional royalties due under these license agreements cannot be reasonably estimated by management.
License fee payments received by the Acacia Technologies group that do not meet the revenue recognition criteria described above are deferred until the revenue recognition criteria are met.  The Acacia Technologies group assesses collectionWe assess the collectibility of accrued license fees receivable based on a number of factors, including past transaction history and credit-worthiness.credit-worthiness of licensees.  If it is determined that collection is not reasonably assured, the fee is recognized when collectibility becomes reasonably assured, assuming all other revenue recognition criteria have been met, which is generally upon receipt of cash. As a result of our licensing

Cash and any related intellectual property enforcement activities that we choose to conduct, we may recognize royalty revenues that relate to prior period infringements by licensees. Differences between amounts initially recognized and amounts subsequently audited or reported as an adjustment to those amounts will be recognized in the period the adjustment is determined as a change in accounting estimate. CASH AND CASH EQUIVALENTS. Cash Equivalents.  We consider all highly liquid, short-term investments with original maturities of three months or less when purchased to be cash equivalents.

Short-term Investments.  Our short-term investments are held in a variety of interest bearing instruments including U.S. government debt securities, high-grade corporate bonds, commercial paper, auction rate securities, money market accounts, certificates of deposit and other high-credit quality marketable securities.  Investments in securities with original maturities of greater than three months and less than one year and other investments representing amounts that are available for current operations are classified as short-term investments.  Investments are classified into categories in accordance with the provisions of Statement of Financial Accounting Standards ("SFAS"(“SFAS”) No. 115, "Accounting“Accounting for Certain Investments in Debt and Equity Securities" ("Securities” (“SFAS No. 115"115”).  At December 31, 20042007 and 2003,2006, all of our investments are classified as available-for-sale, which are reported at fair value with related unrealized gains and losses in the value of such securities recorded as a separate component of comprehensive income (loss) in stockholders'stockholders’ equity until realized. During 2002, certain of our investments were classified as trading securities. Realized and unrealized gains and losses in the value of trading securities are included in net loss in the consolidated statements of operations and comprehensive loss.

The fair value of our investments is determined by quoted market prices.  Realized and unrealized gains and losses are recorded based on the specific identification method.  For investments classified as available-for-sale, unrealized losses that are other than temporary are recognized in net loss. the consolidated statement of operations and comprehensive income (loss) (hereinafter “consolidated statement of operations”).  An impairment is deemed other than temporary unless (a) we have the ability and intent to hold an investment for a period of time sufficient for recovery of its carrying amount and (b) positive evidence indicating that the investment's carrying amount is recoverable within a reasonable period of time outweighs any evidence to the contrary. All available evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, the carrying amount of the investment is recoverable within a reasonable period of time.

The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity.  Such amortization is included in interest income (expense).  Interest and dividends on all securities are included in interest income.

At December 31, 20042007 and 2003,2006, we held $11,900,000$10,660,000 and $7,750,000,$7,288,000, respectively of short-term investments, whichinvestment grade securities with an auction reset feature (“auction rate securities”). At December 31, 2007, our auction rate securities consist of securities issued by closed-end investment companies with portfolio asset coverage of at least 200%, and auction rate municipal bonds and variableinvestments backed by student loans, issued under programs such as the Federal Family Education Loan Program, all of which had credit ratings of AAA when purchased.  As of March 5, 2008, we held $6,250,000 in auction rate municipal demand notes classified as available-for-sale securities. securities investments.

Our investments in these securities are recorded at cost, which approximates fair market value due to their variable interest rates, which typically reset every 7 to 35 days, and, despite the long-term nature of their stated contractual maturities, we have the ability to quickly liquidate these securities.maturities.  As a result, we had no cumulative gross unrealized holding gains (losses) or gross realized gains (losses) from our current investments.these investments for the periods presented.  All income generated from these current investments was recorded as interest income. CONCENTRATION OF CREDIT RISKS.

The Dutch auction process that resets the applicable interest rate at predetermined calendar intervals is intended to provide liquidity to the holder of auction rate securities by matching buyers and sellers within a market context enabling the holder to gain immediate liquidity by selling such interests at par or rolling over their investment. If there is an imbalance between buyers and sellers the risk of a failed auction exists.

We have not experienced a failed auction for any of our securities as of December 31, 2007.  However, we did experience failed auctions with certain of our issues in February 2008.  Given the deteriorating credit markets, and the increased incidence of failure within the auction market in February 2008, there can be no assurance as to when we would be able to liquidate a particular issue. In such case of a failure, the auction rate securities continue to pay interest in accordance with their terms, however, we may not be able to access the par value of the invested funds until a future auction of these investments is successful, the security is called by the issuer or a buyer is found outside of the auction process.  Furthermore, if this situation were to persist despite our ability to hold such investments until maturity, we may be required to record an impairment charge in a future period.

Management believes that the fair value of our investments in auction rate securities continue to approximate  their par value and that the underlying credit quality of the assets backing its auction rate securities investments have not been impacted by the reduced liquidity of these investments subsequent to December 31, 2007.  We will continue to monitor and evaluate our investments in auction rate securities for any further reduction in liquidity and potential impairment in future periods.

Acacia Research Corporation performs regular credit evaluations of its significant licensees and customers and has not experienced any significant credit losses. Substantially all of the components

Property and raw materials used in the manufacture of the CombiMatrix group's products, including semiconductors and reagents, are currently provided from a limited number of sources or in some cases from a single source. Although the CombiMatrix group believes that alternative sources for those components and raw materials are available, any supply interruption in a sole-sourced component or raw material might result in up to a several-month production delay and materially harm the CombiMatrix group's ability to manufacture products until a new source of supply, if any, could be located and qualified. The CombiMatrix group utilizes non-standard semiconductor manufacturing processes to fabricate the electrode array that is a key aspect of the array structure. Although the CombiMatrix group has a supply agreement in place with a semiconductor wafer manufacturer to ensure availability of the raw materials, it does not guarantee a permanent supply. INVENTORY. Inventory, which consists primarily of raw materials to be used in the production of our array products, is stated at the lower of cost or market using the first-in, first-out method. PROPERTY AND EQUIPMENT. Equipment.  Property and equipment are recorded at cost. Major additions and improvements that materially extend useful lives of property and equipment are capitalized. Maintenance and repairs are charged against the results of operations as incurred.  When these assets are sold or otherwise disposed of, the asset and related depreciation are relieved, and any gain or loss is included in the consolidated statement of operations and comprehensive loss for the period of sale or disposal. Depreciation is computed on a straight-line basis over the following estimated useful lives of the assets: Machine shop and laboratory equipment.......

Goodwill and identifiable intangibles, including patents, are recorded when the consideration paid for acquisitions exceeds the fair value of the net tangible assets acquired.

Patents. Patents, once issued or purchased, are amortized on the straight-line method over their remaining economic useful lives, ranging from threetwo to twentyseven years. Goodwill is not amortized. IMPAIRMENT OF LONG-LIVED ASSETS AND GOODWILL.

Impairment of Long-lived Assets. We review long-lived assets and intangible assets for potential impairment annually and when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset'sasset’s carrying value over its fair value is recorded.  If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available.  If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. Goodwill is evaluated for impairment in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets" ("SFAS No. 142") and is subject to a periodic review for potential impairment at a reporting unit level. Reviews for potential impairment must occur at least annually and may be performed earlier, if circumstances indicate that an impairment may have occurred.

Fair Value of goodwill F-11 impairment as of December 31 of each year. Our two reporting units as of December 31, 2004 are: 1) the Acacia Technologies group and 2) the CombiMatrix group. The fair values of our reporting units are estimated using a discounted cash flow analysis and by reference to quoted market prices of Acacia Research Corporation's classes of stock. SFAS No. 142 requires us to compare the fair value of our reporting units to their carrying amounts on an annual basis to determine if there is potential goodwill impairment. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the fair value of the goodwill within the reporting unit is less than its carrying value. There can be no assurance that future goodwill impairment tests will not result in a charge to earnings. As a result of the August 2004 adverse ruling in Soundview Technologies' V-chip related litigation described at Note 13, as of September 30, 2004, Soundview Technologies was no longer considered a reporting unit of the Acacia Technologies group.

Stock-Based Compensation. Effective January 1, 2006, Acacia Research Corporation hasadopted the provisions of Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123R”), which sets forth the accounting requirements for “share-based” compensation payments to employees and non-employee directors and requires that compensation cost relating to share-based payment transactions be recognized in the statement of operations. The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense, on a straight-line basis, over the employee’s requisite service period (generally the vesting period of the equity award) which is generally two to four years.

The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model.  The fair value of restricted stock awards is determined by the product of the number of shares granted and the grant date market price of the underlying common stock.  

SFAS No. 123R requires stock-based employee compensation plans, whichexpense to be recorded only for those awards expected to vest using an estimated forfeiture rate.  Acacia Research Corporation estimates pre-vesting option forfeitures at the time of grant and reflects the impact of estimated pre-vesting option forfeitures on compensation expense recognized.  To the extent that actual results differ from our estimates, such amounts will be recorded as cumulative adjustments in the period the estimates are described more fullyrevised.  

We adopted SFAS No. 123R using the modified prospective transition method.  Under this transition method, compensation cost recognized for the periods presented includes: (i) compensation cost for all stock-based awards granted prior to, but not yet vested as of January 1, 2006 (based on the grant-date fair value estimated in Note 12. Compensationaccordance with the original provisions of SFAS No. 123 and previously presented in the pro forma footnote disclosures), and (ii) compensation cost for all stock-based awards granted subsequent to January 1, 2006 (based on the grant-date fair value estimated in accordance with the new provisions of SFAS No. 123R).

  The fair value of stock options issuedgranted during the years ended December 31, 2007 and 2006 were estimated using the Black-Scholes option-pricing model, based on the following weighted-average assumptions:

SFAS No. 123R does not require the recording of deferred stock compensation charges in stockholder’s equity on the grant date of a stock-based award.  As such, all deferred stock compensation information above gives effect to the recapitalization as of January 1, 2002. As a result, stock-based compensation informationcharges previously recorded under APB No. 25, totaling $1,400,000 at December 31, 2005, related to restricted stock awards, were reversed upon adoption of SFAS No. 123R, with a corresponding reduction being recorded in consolidated additional paid-in capital.
Acacia Research Corporation common stockadopted the alternative transition method provided in 2002 has been omitted fromFASB Staff Position No. 123(R)-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards.”  The alternative transition method includes a simplified method to establish the table above. (2) The fair valuebeginning balance of stock options was determined using the Black-Scholes option-pricing model. The fair value calculations assume no expected dividends. RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses consist of costs incurred for direct and overhead-related research expenses and are expensed as incurred. Costs to acquire technologies, which are utilized in research and development and which have no alternative future use are expensed when incurred. Costsadditional paid-in-capital pool (“APIC pool”) related to filing and pursuing patent applications are expensed as incurred, as recoverabilitythe tax effects of such expendituresemployee stock-based compensation which is uncertain. Software developed for use in our products is expensed as incurred until both (i) technological feasibility for the software has been established and (ii) all research and development activities for the other components of the system have been completed. We believe these criteria are met after we have received evaluations from third-party test sites and completed any resulting modificationsavailable to absorb tax deficiencies recognized subsequent to the products. Expenditures to date have been classified as research and development expense. ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT. The value assigned to acquired in-process research and development ("IPR&D") is determined by identifying acquired specific in-process research and development projects that would be continued and for which (a) technological feasibility has not been established at the acquisition date, (b) there is no alternative future use and (c) the fair value is estimable with reasonable reliability, upon consummationadoption of a business combination. ADVERTISING. Costs associated with marketing and advertising of the CombiMatrix group's products and services are expensed as incurred. For the years ended December 31, 2004, 2003 and 2002, marketing and advertising expenses incurred by the CombiMatrix group were $314,000, $26,000 and $62,000, respectively. INCOME TAXES. SFAS 123(R).

Income Taxes.  Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in Acacia Research Corporation'sCorporation’s consolidated financial statements or consolidated tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized. ACCOUNTING FOR SALES OF STOCK BY A SUBSIDIARY. Gains

Effective January 1, 2007, Acacia Research Corporation adopted FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes,” which clarifies the accounting for uncertainty in income taxes recognized in the financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes.” FIN 48 provides guidance on the financial statement recognition and measurement of a tax position taken or losses resultingexpected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosures, and transition.  In accordance with FIN 48, a tax position is a position in a previously filed tax return or a position expected to be taken in a future tax filing that is reflected in measuring current or deferred income tax assets and liabilities. Tax positions shall be recognized only when it is more likely than not (likelihood of greater than 50%), based on technical merits, that the position will be sustained upon examination. Tax positions that meet the more likely than not threshold should be measured using a probability weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement.  The adoption of FIN 48 did not have a material impact on our consolidated financial position, results of operations or cash flows.

The total amount of unrecognized tax benefits as of January 1, 2007 and December 31, 2007 was $56,000 and $115,000, respectively, all of which, if recognized, would affect the effective tax rate. 
Acacia Research Corporation recognizes interest and penalties with respect to unrecognized tax benefits in income tax expense.  We have identified no uncertain tax position for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within 12 months.
Acacia Research Corporation is subject to taxation in the U.S. and various state jurisdictions. With no material exceptions, Acacia Research Corporation is no longer subject to U.S. federal or state examinations by tax authorities for years before 2001.  

At December 31, 2007, Acacia Research Corporation had U.S. federal and state income tax net operating loss carryforwards as summarized at Note 9.  Due to uncertainties surrounding our ability to generate future taxable income to realize these assets, a full valuation allowance has been established to offset our net deferred tax assets.  All NOLs and tax credits generated by the continuing operations of Acacia Research Corporation and its operating subsidiaries have been retained by Acacia Research Corporation subsequent to the Split-off Transaction.  Subsequent to the Split-off Transaction, all NOLs and tax credits generated by CombiMatrix Corporation and its subsidiaries have been retained by CombiMatrix Corporation and are not available to Acacia Research Corporation.

ACACIA RESEARCH CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Utilization of the NOL and R&D credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change” as defined by Section 382 of the Code results from a subsidiary's saletransaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups.  Since Acacia Research Corporation’s formation, we have raised capital through the issuance of capital stock on several occasions (both before and after its public offering) which, combined with the purchasing stockholders’ subsequent disposition of those shares, may have resulted in such an ownership change, or could result in an ownership change in the future upon subsequent disposition.

We have not completed a study to third partiesassess whether an ownership change has occurred or whether there have been multiple ownership changes since our formation due to the complexity and cost associated with such a study, and the fact that there may be additional such ownership changes in the future. If we have experienced an ownership change at a price per share in excessany time since our formation, utilization of the NOL or belowR&D credit carryforwards would be subject to an annual limitation under Section 382 of the Code, which is determined by first multiplying the value of Acacia Research Corporation's average carrying amount per sharestock at the time of the ownership change by the applicable long-term, tax-exempt rate, and then could be subject to additional adjustments, as required. Any limitation may result in expiration of a portion of the NOL or R&D credit carryforwards before utilization. Further, until a study is completed and any limitation known, no amounts are generally reflectedbeing considered as an uncertain tax position or disclosed as an unrecognized tax benefit under FIN 48. Due to the existence of a full valuation allowance, future changes in stockholders' equityour unrecognized tax benefits will not impact our effective tax rate. Any carryforwards that will expire prior to utilization as a direct increase or decrease to capital in excessresult of par or stated value. COMPREHENSIVE (LOSS) INCOME. such limitations will be removed from deferred tax assets with a corresponding reduction of the valuation allowance.

Comprehensive Income (Loss).  Comprehensive income (loss) income is the change in equity from transactions and other events and circumstances other than those resulting from investments by owners and distributions to owners. SEGMENT REPORTING.

Segment Reporting.  We use the management approach, which designates the internal organization that is used by management for making operating decisions and assessing performance as the basis of Acacia Research Corporation'sCorporation’s reportable segments. USE OF ESTIMATES.

Use of Estimates.  The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.  EARNINGS PER SHARE. We believe that, of the significant accounting policies described herein, the accounting policies associated with revenue recognition, stock-based compensation expense, valuation of long-lived and intangible assets and impairment of marketable securities, require our most difficult, subjective or complex judgments.

Earnings (Loss) Per Share.Basic earnings per share for each class of common stock is computed by dividing the income or loss allocated to each class of common stock by the weighted averageweighted-average number of outstanding shares of that class of common stock. Diluted earnings per share is computed by dividing the income or loss allocated to each class of common stock by the weighted averageweighted-average number of outstanding shares of that class of common stock, including the dilutive effect of common stock equivalents. Potentially dilutive common stock equivalents primarily consist of employee stock options, unvested restricted stock, restricted stock unit grants and common stock purchase warrants. F-13 warrants (AR-CombiMatrix stock only).

The earnings or losses allocated to each class of common stock are determined by Acacia Research Corporation'sCorporation’s board of directors. This determination is generally based on the net income or loss amounts of the corresponding group determined in accordance with accounting principles generally accepted in the United States of America, consistently applied.  Acacia Research Corporation believesWe believe this method of allocation isto be systematic and reasonable.

As a result, holders of AR-CombiMatrix stock and AR-Acacia Technologies stock continue to be subject to all of the risks of an investment in Acacia Research Corporation and all of its businesses, assets and liabilities. The assets Acacia Research Corporation attributes to one of the groups could be subject to the liabilities of the other group. The group financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, and taken together, comprise all the accounts included in the corresponding consolidated financial statements of Acacia Research Corporation. The financial statements of the groups reflect the financial condition, results of operations, and cash flows of the businesses included therein. The financial statements of the groups include the accounts or assets of Acacia Research Corporation specifically attributed to the groups and were prepared using amounts included in Acacia Research Corporation's consolidated financial statements. Minority interests represent participation of other stockholders in the net equity and in the division earnings and losses of the groups and are reflected in the caption "Minority interests" in the group financial statements. Minority interests adjust group net results of operations to reflect only the group's share of the division earnings or losses of non-wholly owned investees. Financial effects arising from one group that affect Acacia Research Corporation's results of operations or financial condition could, if significant, affect the results of operations or financial condition of the other group and the market price of the class of common stock relating to the other group.

MANAGEMENT ALLOCATION POLICIES. The management and allocation policies applicable to the preparation of the financial statements of the CombiMatrix group and the Acacia Technologies group may be modified or rescinded, or additional policies may be adopted, at the sole discretion of the Acacia Research Corporation board of directors at any time without approval of the stockholders. The group's financial statements reflect the application of the management and allocation policies adopted by the Acacia Research Corporation board of directors to various corporate activities, as described below. F-14 Management has no plans to change allocation methods or the composition of the groups. The group financial statements should be read in conjunction with the Acacia Research Corporation consolidated financial statements and related notes. TREASURY AND CASH MANAGEMENT POLICIES. Cash and cash equivalents and short-term investments are attributed to the groups based on the respective cash and cash equivalents and short term investments balances of the entities comprising each group. Acacia Research Corporation's cash and the cash held by its intellectual property licensing businesses, including all cash raised through Acacia Research Corporation's previous offerings, have been attributed to the Acacia Technologies group as these funds are intended to support the intellectual property licensing businesses of Acacia Research Corporation. All cash raised by CombiMatrix Corporation and Advanced Material Sciences have been attributed to the CombiMatrix group. Acacia Research Corporation manages most treasury and cash management activities on a decentralized basis, with each group separately managing its own treasury activities. Pursuant to treasury and cash management policies adopted by the Acacia Research Corporation board of directors, the following applies: o Acacia Research Corporation will attribute each future issuance of AR-Acacia Technologies stock (and the proceeds thereof) to the Acacia Technologies group and will attribute each future issuance of AR-CombiMatrix stock (and the proceeds thereof) to the CombiMatrix group; o Acacia Research Corporation will attribute each future incurrence or issuance of external debt or preferred stock (and the proceeds thereof), if any, between the groups or entirely to one group as determined by the Acacia Research Corporation board of directors, based on the extent to which Acacia Research Corporation incurs or issues the debt or preferred stock for the benefit of the CombiMatrix group or the Acacia Technologies group; o Dividends, if any, on AR-Acacia Technologies stock will be charged against the Acacia Technologies group, and dividends, if any on AR-CombiMatrix stock will be charged against the CombiMatrix group; o Repurchases of AR-Acacia Technologies stock will be charged against the Acacia Technologies group and repurchases of AR-CombiMatrix stock will be charged against the CombiMatrix group; o Acacia Research Corporation accounts for any cash transfers from Acacia Research Corporation to or for the account of a group, from a group to or for the account of Acacia Research Corporation, or from one group to or for the account of the other group (other than transfers in return for assets or services rendered) as short-term loans unless (i) the Acacia Research Corporation board of directors determines that a given transfer (or type of transfer) should be accounted for as a long-term loan, (ii) the Acacia Research Corporation board of directors determines that a given transfer (or type of transfer) should be accounted for as a capital contribution or (iii) the Acacia Research Corporation board of directors determines that a given transfer (or type of transfer) should be accounted for as a return of capital. There are no specific criteria to determine when Acacia Research Corporation will account for a cash transfer as a long-term loan, a capital contribution or a return of capital rather than an inter-group revolving credit advance; provided, however, that cash advances from Acacia Research Corporation to the Acacia Technologies group or to the CombiMatrix group up to $25.0 million on a cumulative basis shall be accounted for as short-term or long-term loans at interest rates at which Acacia Research Corporation could borrow such funds and shall not be accounted for as a capital contribution. The Acacia Research Corporation board of directors will make such a determination in the exercise of its business judgment at the time of such transfer based upon all relevant circumstances. Factors the Acacia Research Corporation board of directors may consider include, without limitation, the current and projected capital structure of each group; the financing needs and objectives of the recipient group; the availability, cost and time associated with alternative financing sources; and prevailing interest rates and general economic conditions; and F-15 o Any cash transfers accounted for as short-term loans will bear interest at the rate at which Acacia Research Corporation could borrow such funds. In addition, any cash transfers accounted for as a long-term loan will have interest rates, amortization, maturity, redemption and other terms that reflect the then-prevailing terms on which Acacia Research Corporation could borrow such funds. ASSETS AND LIABILITIES. Acacia Research Corporation's assets and liabilities have been attributed to the Acacia Technologies group and the CombiMatrix group based on the respective asset and liabilities of the business comprising each group. Net intangible assets recorded at the Acacia Research Corporation level, primarily consisting of acquired patents and goodwill balances, have been attributed to the respective businesses comprising each group to which the intangibles and goodwill relate. CORPORATE GENERAL AND ADMINISTRATIVE SERVICES AND FACILITIES. Acacia Research Corporation allocates the cost of corporate general and administrative services and facilities between the groups generally based upon utilization. Where determinations based on utilization alone are impracticable, Acacia Research Corporation utilizes other methods and criteria that management believes to be equitable and to provide a reasonable estimate of the cost attributable to each group. Except as otherwise determined by management, the allocated costs of providing such services and facilities include, without limitation, all costs and expenses of personnel employed in connection with such services and facilities, including, without limitation, all direct costs of such personnel, such as payroll, payroll taxes and fringe benefit costs (calculated at the appropriate annual composite rate therefore) and all overhead costs and expenses directly related to such personnel and the services or facilities provided by them. In addition, allocated costs include all materials used in connection with such services or facilities, billed at their net cost to the provider of the services or facilities plus all overhead costs and expenses related to such materials. Except as may otherwise be specifically provided pursuant to the terms of any agreements among Acacia Research Corporation and the groups or any resolutions of the Acacia Research Corporation board of directors, the corporate general and administrative services and facilities to be allocated between the groups include, without limitation, legal services, accounting services (tax and financial), insurance and deductibles payable in connection therewith, employee benefit plans and administration thereof, investor relations, stockholder services, and services relating to the board of directors. Direct salaries, payroll taxes and fringe benefits are allocated to the groups based on the percentage of actual time incurred by specific employees to total annual time available and direct costs including, postage, insurance, legal fees, accounting and tax and other are allocated to the groups based on specific identification of costs incurred on behalf of each group. Other direct costs, including direct depreciation expense, computer costs, general office supplies and rent are allocated to the groups based on the ratio of direct salaries to total salaries. Indirect costs, including indirect salaries and benefits, investor relations, rent, general office supplies and indirect depreciation are allocated to the groups based on the ratio of direct salaries for each group to total direct salaries. Included in marketing, general and administrative expenses of the Acacia Technologies group are allocated corporate charges of $3,395,000, $2,864,000 and $4,906,000 relating to the periods ending December 31, 2004, 2003 and 2002, respectively. Included in marketing, general and administrative expenses of the CombiMatrix group are allocated corporate charges of $689,000, $894,000 and $1,161,000 relating to the periods ending December 31, 2004, 2003 and 2002, respectively. Management believes that the methods and criteria used to allocate costs are equitable and provide a reasonable estimate of the cost attributable to the groups. Based on the allocation methods used, Acacia Research Corporation believes that the allocation of expenses as presented in the accompanying consolidating financial information reflects a reasonable estimation of expenses that would be recognized if the groups were separate stand-alone registrants. ALLOCATION OF FEDERAL AND STATE INCOME TAXES. Acacia Research Corporation determines its federal income taxes and the federal income taxes of its subsidiaries that own assets allocated between the groups on a consolidated basis. Acacia Research Corporation allocates consolidated federal income tax provisions and related tax payments or refunds between the Acacia Technologies' group and CombiMatrix group based principally on the taxable income and tax credits directly attributable to each group. Such allocations reflect each group's contribution, whether positive or negative, to Acacia Research Corporation's consolidated federal taxable income and consolidated federal tax liability and tax credit position. Acacia Research Corporation will credit tax benefits that cannot be used by the group generating those benefits but can be used on a consolidated tax return basis to the group that generated such benefits. F-16 Inter-group transactions are treated as taxed as if each group was a stand-alone company. Depending on the tax laws of the respective jurisdictions, state and local income taxes are calculated on either a consolidated or combined basis between the groups based on their respective contribution to such consolidated or combined state taxable incomes. State and local income tax provisions and related tax payments or refunds which are determined on a separate corporation basis are allocated between the groups in a manner designed to reflect the respective contributions of the groups to Acacia Research Corporation's separate or local taxable income.

SFAS No. 141R also establishes disclosure requirements to enable the evaluation of the enterprise or (b) liabilities that are based on the fair valuenature and financial effects of the enterprise's equity instruments or that may be settled by the issuance of such equity instruments.business combinations. SFAS No. 123(R) will require141R is effective for Acacia Research Corporation to measure all employee stock-based compensation awards using a fair-value method and record such expense in its consolidated and separate group financial statements. The adoptionas of SFAS No. 123(R) will require additional accounting related toJanuary 1, 2009. We are currently evaluating the income tax effects and additional disclosure regarding the cash flow effects resulting from share-based payment arrangements. SFAS No. 123(R) is effective beginning in the quarter ending September 30, 2005. The effectpotential impact of the adoption of SFAS No. 123(R) is expected to be comparable to the effect disclosed141R on a pro forma basis resulting from the application of the current fair-value recognition provisions of SFAS No. 123, as shown in Note 2 above. In December 2004, the FASB issued SFAS No. 153 "Exchanges of Nonmonetary Assets, an amendment of APBO 29" to address the accounting for nonmonetary exchanges of productive assets. SFAS No. 153 amends APBO 29, "Accounting for Nonmonetary Exchanges," which established a narrow exception from fair-value measurement for nonmonetary exchanges of similar productive assets. SFAS No. 153 eliminates that exception and replaces it with an exception for exchanges that do not have commercial substance. Under SFAS No. 153 nonmonetary exchanges are required to be accounted for at fair value, recognizing any gains or losses, if their fair value is determinable within reasonable limits and the transaction has commercial substance. SFAS No. 153 specifies that a nonmonetary exchange has commercial substance if future cash flows of the entity are expected to change significantly as a result of the exchange. The provisions of SFAS No. 153 apply to nonmonetary asset exchanges in fiscal periods beginning after June 15, 2005. Adoption of SFAS No. 153 is not expected to have a material impact on Acacia Research Corporation's, the CombiMatrix group's or the Acacia Technologies group'sour consolidated financial position, results of operations or cash flows.
In November 2004,December 2007, the FASB issued SFAS No. 151, "Inventory Costs - 160, Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARBAccounting Research Bulletin No. 43, chapter 4." 51 (“SFAS No. 151 requires that "abnormal" amounts160”). SFAS 160 establishes accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of idle facility expense, freight, handling costs, and wasted material are to be recognized as current-period charges rather than as components of inventory. The statement also requires that allocation of fixed production overheadsconsolidated net income attributable to the costsparent and to the noncontrolling interest, changes in a parent’s ownership interest, and the valuation of conversion be based onretained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS No. 160 also establishes disclosure requirements that clearly identify and distinguish between the normal capacityinterests of the production facilities.parent and the interests of the noncontrolling owners. SFAS No. 160 is effective for Acacia Research Corporation adopted SFAS No. 151 duringbeginning January 1, 2009. We are currently evaluating the fourth quarterpotential impact of 2004.

The consensus indicates that costs incurred and revenues generated from transactions with third parties should be reported by the collaborators on the respective line items in their income statements pursuant to EITF Issue No. 99-19, “Reporting Revenue Gross as a Principal Versus Net as an Investor Should ApplyAgent.”  Additionally, the Equity Methodconsensus provides that income statement characterization of Accountingpayments between the participants in a collaborative arrangement should be based upon existing authoritative pronouncements; analogy to Investments Other Than Common Stock."such pronouncements if not within their scope; or a reasonable, rational, and consistently applied accounting policy election.

 In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities Including an Amendment of FASB Statement No. 115 (“SFAS No. 159”).  SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value, with unrealized gains and losses related to these financial instruments reported in earnings at each subsequent reporting date.  SFAS No. 159 is effective for Acacia Research Corporation beginning January 1, 2008. We do not expect the adoption of SFAS No. 159 to have a material impact, if any, on our consolidated financial position, results of operations and cash flows.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (“SFAS No. 157”). SFAS No. 157 establishes a common definition for fair value to be applied to U.S. generally accepted accounting principles guidance requiring use of fair value, establishes a framework for measuring fair value, and expands disclosure about such fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007.  In February 2008, the FASB issued FSP SFAS No. 157–1 which amends SFAS No. 157 to exclude FASB Statement No. 13, Accounting for Leases, and other accounting pronouncements that address fair value measurements for purposes of lease classification or measurement under Statement 13.  In February 2008, the FASB issued FSP SFAS No. 157-2 (“FSP 157-2”) which would delay the effective date of SFAS No. 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). FSP 157-2 partially defers the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008, and interim periods within those fiscal years for items within the scope of FSP 157-2.  We do not expect the adoption of SFAS No. 157 to have a material impact, if any, on our consolidated financial position, results of operations and cash flows.

6.             INVESTMENTS In October 2004 (the "Investment Date"), the CombiMatrix group entered into an agreement to acquire up to a one-third ownership interest in Leuchemix, Inc. ("Leuchemix"), a private drug development firm, which is developing several compounds for the treatment of leukemia and other cancers. In accordance with the terms of the purchase agreement, the CombiMatrix group will purchase 3,137,500 shares of Series A Preferred Stock of Leuchemix for a total purchase price of $4,000,000. The ownership interest will be acquired and paid for quarterly, beginning with the fourth quarter of 2004 and continuing through the third quarter of 2006. As of December 31, 2004, the CombiMatrix group has initially invested $250,000 for a 3% interest in the total outstanding voting securities of Leuchemix. In accordance with the terms of the purchase agreement, CombiMatrix Corporation's CEO was named a director of Leuchemix. Although the CombiMatrix group's investment in Leuchemix only represented approximately 3% of Leuchemix's total outstanding voting securities as of the Investment Date, the CombiMatrix group's investment is being accounted for under the equity method as the CombiMatrix group has the ability to exercise significant influence over Leuchemix, primarily due to CombiMatrix Corporation's representation on Leuchemix's board of directors. The CombiMatrix group's 3% interest in the equity in loss of Leuchemix, including its share of the amortization expense related to the excess purchase consideration over the book value of Leuchemix was not material for the year-ended December 31, 2004. Future investments in Leuchemix will be accounted for as step acquisitions. Summary financial information for Leuchemix was not significant as of December 31, 2004. F-19 In the second quarter of 2003, the Acacia Technologies group recorded an impairment charge of $207,000 for an other-than-temporary decline in the fair value of its cost method investment in Advanced Data Exchange ("ADX"). Impairment indicators included a continued decline in the working capital of the entity and reference to a recent equity transaction and related valuation indicating an other-than-temporary decline in fair value of the investment. In September 2002, we recorded an impairment charge of $2,748,000 for an other-than-temporary decline in the fair value of ADX. Impairment indicators included recurring losses, a decline in working capital and the completion of a recent equity transaction with a shareholder at an amount below our carrying value. The fair value of our investment in ADX was determined by reference to available financial and market information. On April 25, 2002, CombiMatrix Corporation purchased our interest in Advanced Material Sciences. CombiMatrix Corporation issued 180,982 shares of its common stock in exchange for our 58% interest in Advanced Material Sciences. As a result of the sale of our interest in Advanced Material Sciences, as of December 31, 2002 CombiMatrix Corporation owned 87% of Advanced Material Sciences and the remaining interests are owned by unaffiliated entities. The purchase was accounted for pursuant to APB Opinion No. 16, "Business Combinations," and related interpretations and EITF 90-5, "Exchanges of Ownership Interests between Entities under Common Control." Accordingly, the transaction was accounted for using PATENTS
Acacia Research Corporation's basis in the net assets of Advanced Material Sciences and as a result, Acacia Research Corporation's 2002 consolidated financial statements reflect the assets and liabilities of Advanced Material Sciences at historical cost. 7. INTANGIBLES The Acacia Technologies group had $121,000 and $1,776,000 of goodwill at December 31, 2004 and 2003, respectively.

The in-process technologiespatents and patent rights acquired were valued using a discounted cash flow model on a project-by-projectpatent portfolio by portfolio basis, which estimated the future net cash flows expected to result from the licensing of each project once it has reached technological feasibility.portfolio, taking into account potential infringers of the patents, usage of the underlying technologies, estimated license fee revenues, contingent legal fee arrangements, inventor royalties due to former patent holders, other estimated costs, tax implications and other factors.  A discount rate consistent with the risks of each projectassociated with achieving the estimated net cash flows was used to estimate the present value of future estimated net cash flows.  In estimating future cash flows, management considered the contribution of its core technology (for which a United States patent was obtainedManagement’s valuation resulted in July 2000) that would be required for successful exploitation of purchased in-process technology, in order to value the core and in-process technologies discretely. As a result, future cash flows relating to each purchased IPR&D project were reduced in order to reflect the contribution of core technology to each IPR&D project. The cash flows from these projects attributable to core technology were then separately valued to determine the intangible assetan estimated fair value of purchased core technology. In determiningpatent related assets acquired of approximately $27,000,000, resulting in approximately $1,900,000 of excess fair value over the contributioncost of core technology to in-process projects, management usednet assets acquired, which has been allocated as a profit split approach which considered the estimated profit split between a licensor and licensee of the core technology and management's assessment of how critical the core technology waspro rata reduction to the IPR&D projects. The nature of the efforts to develop the purchased IPR&D into commercially viable products principally relates to the completion and/or acceleration of existing development programs. These efforts include testing current and alternative materials used in array design, testing of existing and alternative methods for array synthesis, developing prototype machinery (including operating software) to synthesize, hybridize and read individual arrays, and to perform numerous experiments, or assays, with actual target samples in order to determine customer protocols and procedures for using the CombiMatrix group's array system. Following is a brief description of the two IPR&D projects identified. Genomics Biological Array System: CombiMatrix Corporation's genomics biological array processor system is being developed to discretely immobilize sequences of DNA or RNA within individual test sites on a modified semiconductor chip coated with a three-dimensional layer of porous material. The system also includes proprietary hardware units and related software applications to be able to synthesize materials onto the chips, apply target samples of genetic materials and interpret the results. The fair valueamounts that otherwise would have been assigned to the genomics biological array system IPR&D project was $13,978,000. A risk-adjusted discount rateassets acquired, in accordance with the purchase method of 32% was appliedaccounting.

In connection with the acquisition described above, Acacia Global Acquisition Corporation entered into a consulting agreement with the former CEO of Global Patent Holdings, LLC.  The agreement required the payment of $2,000,000 in consulting fees over a two-year period, and certain reimbursable consulting related expenses, commencing on the date of acquisition. Marketing, general and administrative expenses for the years ended December 31, 2007, 2006 and 2005 include $103,000, $1,087,000 and $1,009,000, respectively, in expenses related to the project's estimated cash flows. Proteomics Biological Array System: CombiMatrix Corporation's proteomics biological array processor system is being developed to discretely immobilize proteinsconsulting agreement.  The consulting agreement expired in January 2007.

The acquisition was treated for tax purposes as a taxable asset acquisition and, other small molecules within individual test sites on a modified semiconductor chipas such, there were no book/tax basis differences associated with the acquisition.  As such, Acacia Research Corporation did not record any deferred income taxes in a similar fashion as described above forconnection with the genomics biological array system. The proteomics biological array system is used for detection and identificationapplication of bio-threat agents in CombiMatrix Corporation's biological and chemical threat agent detector development programs that are currently in process. The fair value assigned to the proteomics biological array system IPR&D project was $3,259,000. A risk-adjusted discount ratepurchase method of 60% was applied toaccounting.

Acacia Research Corporation completed a private equity financing, raising gross proceeds of $5,247,000 through the issuance of 2,385,000 units. Each unit consists of one share of AR-CombiMatrix common stock and one-half, five-year callable common stock purchase warrant. Each full common stock purchase warrant entitles the holder to purchase a share of AR-CombiMatrix stock at a price of $2.75 per share and is callable by Acacia Research Corporation beginning in May 2004 once the daily average of the high and low prices of Acacia Research Corporation's AR-CombiMatrix stock on the Nasdaq SmallCap Market is equal to or above $4.50 for 20 consecutive trading days. Acacia Research Corporation issued an additional 31,502 shares of AR-CombiMatrix stock in lieu of cash payments in conjunction with the private placement for finder's fees. Net proceeds raised from the private equity financing of $4,862,000 were attributed to the CombiMatrix group. In September 2002, CombiMatrix Corporation issued 4,016,346 shares of its common stock to Nanogen, Inc. ("Nanogen") in settlement of all outstanding litigation between the parties (see Note 13). As a result of the transaction, Acacia Research Corporation's equity ownership in CombiMatrix Corporation decreased from 58% to 48%. A loss totaling $550,000, resulting from CombiMatrix Corporation's issuance of stock to a third party at a value per share below our carrying amount per share has been reflected as a direct reduction to additional paid-in capital in consolidated stockholders' equity.

At December 2002,31, 2007, Acacia Research Corporation increased its ownership interest in CombiMatrix Corporation from 48% to 100%. As a result of the increase in ownership, Acacia Research Corporation files a consolidatedhad U.S. federal income tax returns that includes the Acacia Technologies group (excluding discontinued operations) and the CombiMatrix group. At December 31, 2004, consolidated U.S. Federal and state income tax net operating loss carry forwards ("NOLs"(“NOLs”), excluding NOLs related to subsidiaries for which we do not file a consolidated tax return, weretotaling approximately $138,835,000$58,258,000 and $38,659,000,$41,961,000, expiring between 20052010 and 2024.2027, and 2008 and 2017, respectively.  In addition, weAcacia Research Corporation had consolidated tax credit carryforwards of approximately $2,931,000. The amount of the CombiMatrix Corporation NOLs and tax credits acquired, totaling approximately $90,131,000 (expiring between 2011 and 2024) and $2,869,000, respectively, that can be utilized annually to offset future taxable income or tax liability has been limited under the Internal Revenue Code due to the ownership change resulting from our December 2002 increase in ownership interest in CombiMatrix Corporation to 100%. $40,000.

As of December 31, 2004, the aggregate tax NOLs at other subsidiaries for which we do not file a consolidated tax return are2007, approximately $20,252,000 for federal income tax purposes, expiring between 2018 and 2024. However, the use of these NOLs is limited to the separate earnings of the respective subsidiaries. In addition, ownership changes may also restrict the use of NOLs and tax credits. Had the Acacia Technologies group and the CombiMatrix group each filed separate tax returns, the provision (benefit) for income taxes and division net income (loss) would not have differed from the amounts reported in Acacia Research Corporation's statement of operations for the years ended December 31, 2004, 2003, and 2002. As of December 31, 2004, approximately $9,844,000$11,762,000 of the valuation allowance related to the tax benefits of stock option deductions included in Acacia Research Corporation'sCorporation’s NOLs. At such time as the valuation allowance is released, the benefit will be credited to additional paid-in capital.  11. DISCONTINUED OPERATIONS Income taxes paid during the periods presented were not material.

During the year ended December 31, 2007, we determined that certain of our deferred tax assets, principally “Basis in affiliates,” and the related full valuation allowance were overstated for the period since December 31, 1996 through December 31, 2006.  The Basis in affiliates amount of approximately $28 million was frozen prior to 2004 since we had acquired the remaining minority interest of the affiliate.  We retroactively corrected our deferred tax asset balances and the related valuation allowance in the deferred tax asset table by approximately $30 million.  The correction had no impact on the consolidated balance sheet, statements of operations, stockholders’ equity or cash flows for any period and there was no other impact to the consolidated financial statements.  Management concluded this correction was not material to the consolidated financial statements.


10.  ACCOUNTING FOR THE SPLIT-OFF OF COMBIMATRIX CORPORATION

In September 2004January 2006, Acacia Research Corporation’s board of directors approved a plan for its wholly owned subsidiary, CombiMatrix Corporation, to become an independent public company.  CombiMatrix Corporation’s registration statement on Form S-1 was declared effective by the SEC on June 8, 2007.  Following the redemption period required by Acacia Research Corporation’s Restated Certificate of Incorporation, on August 15, 2007 (the “Redemption Date”), CombiMatrix Corporation was split-off from Acacia Research Corporation through the redemption of all outstanding shares of AR-CombiMatrix stock in exchange for the distribution of new shares of CombiMatrix Corporation common stock, on a pro-rata basis, to the holders of AR-CombiMatrix stock as of the Redemption Date (the “Split-off Transaction”).  On the Redemption Date, every ten (10) shares of AR-CombiMatrix stock outstanding on August 15, 2007, was redeemed for one (1) share of common stock of CombiMatrix Corporation.  Subsequent to the Redemption Date, Acacia Research Corporation no longer owns any equity interests in CombiMatrix Corporation and 2002, we accrued an additional $104,000the two companies operate independently of each other.

As a result of the Split-off Transaction, the CombiMatrix group is no longer a business group of Acacia Research Corporation.  As a result of the Split-off Transaction, all outstanding shares of AR-CombiMatrix stock were redeemed, and $200,000 (nethence, all rights of minority interests), respectively,holders of AR-CombiMatrix stock ceased as of the Redemption Date, except for the right, upon the surrender to the exchange agent of shares of AR-CombiMatrix stock, to receive new shares of CombiMatrix Corporation stock pursuant to the exchange ratio described above.

The Split-off Transaction was accounted for by Acacia Research Corporation at historical cost.  Accordingly, no gain or loss on disposal was recognized in estimatedthe accompanying consolidated statements of operations. Included in the current period consolidated balance sheet is a charge to consolidated shareholders’ equity totaling $35,444,000, reflecting the distribution of our investment in the net assets of CombiMatrix Corporation to holders of AR-CombiMatrix stock, as of the Redemption Date, as described above.  We received a private letter ruling from the IRS with regard to the U.S. federal income tax consequences of the Split-off Transaction to the effect that the Split-Transaction will be treated as a tax-free exchange under Sections 368 and 355 of the Internal Revenue Code of 1986, as amended.

For the period from January 1, 2007 through August 15, 2007, revenues and pre-tax loss related to CombiMatrix Corporation included in discontinued operations were $2,968,000 and $8,086,000, respectively.  Net loss from discontinued operations for the year ended December 31, 2007, includes direct costs to be incurred in connection with the discontinuedSplit-off Transaction, originally included in Acacia Research Corporation corporate accounts, totaling $136,000 for the year ended December 31, 2007.

The AR-CombiMatrix Group Plan authorizes grants of stock options, stock awardsto eligible individuals, which generally includes directors, officers, employees and performance shares with respect to AR-CombiMatrix stock. Directors and certain officers and key employees with responsibilities involving both the Acacia Technologies group and the CombiMatrix group may be granted awards under both incentive plans in a manner which reflects their responsibilities. The board of directors believes that granting participants awards tied to performance of the group in which the participants work and, in certain cases the other group, is in the best interest of the Acacia Research Corporation and its stockholders.

The conversion ratio for shares of AR-CombiMatrix stock is equal to the quotient obtained by dividing (a) the number of shares of CombiMatrix Corporation common stock owned by Acacia Research Corporation immediately prior to the effective time of the merger by (b) the total number of shares of Acacia Research Corporation common stock issued and outstanding immediately prior to the effective time. The exercise price for the resulting AR-Acacia Technologies stock options and warrants and AR-CombiMatrix stock options and warrants was calculated by multiplying the exercise price under such existing stock option or warrant by a fraction, the numerator of which is the result obtained by multiplying the opening price of the applicable class of common stock underlying such option on the first date such stocks are traded after the recapitalization times the applicable conversion ratio and the denominator of which is the sum of such amounts for the AR-CombiMatrix stock and the AR-Acacia Technologies stock. However, the aggregate intrinsic value of the options was not increased, and the ratio of the exercise price per option to the market value per share was not reduced. The converted options continue to be governed bynoted below, the terms and conditionsprovisions of the original option plans. As a result of the merger transaction with CombiMatrix Corporation,Plans are identical in December 2002 (see Note 8), each outstanding option to purchase shares of CombiMatrix Corporation common stock under CombiMatrix Corporation's 1995 Stock Option Plan, 1998 Stock Option Plan and 2000 Stock Awards Plan, whether or not exercisable, was assumed by all material respects.

Each assumed option continues to be governed by the same terms and conditions that governed it under the applicable CombiMatrix Corporation plan immediately before the effective time of the merger except that the option is exercisable for shares of AR-CombiMatrix stock rather than CombiMatrix Corporation common stock. The number of shares of AR-CombiMatrix stock issuable upon exercise of the assumed option, as well as the exercise price, is the same as the number of shares of CombiMatrix Corporation common stock issuable and exercise price prior to the merger. The exchange of AR-CombiMatrix stock options for CombiMatrix Corporation common stock options is considered a modification (or settlement) of a stock-based compensation arrangement resulting in a new measurement date for the respective awards. The new measurement date for the award modifications was December 13, 2002, the effective date of the merger, and resulted in additional stock-based compensation of $116,000, which was allocated to the CombiMatrix group.

Patent Enforcement and Other Litigation

Acacia Research Corporation is subject to claims, counterclaims and legal actions that arise in the ordinary course of business.  Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on our consolidated financial position, results of operations or cash flows.  From timeOperating subsidiaries of Acacia Research Corporation are often required to time, companies comprising the Acacia Technologies group engage in litigation to enforce their patents. COMBIMATRIX CORPORATION On November 28, 2000, Nanogen filed a complaint in the United States District Court for the Southern District of California against CombiMatrix Corporationpatents and Donald D. Montgomery, Ph.D., an officer, directorpatent rights.

Guarantees and stockholder of CombiMatrix Corporation. Dr. Montgomery was employed by Nanogen as a senior research scientist between May 1994 and August 1995. The Nanogen complaint alleged, among other things, breach of contract, trade secret misappropriation and that U.S. Patent No. 6,093,302 and other proprietary information belonging to CombiMatrix Corporation are instead the property of Nanogen. The complaint sought, among other things, correction of inventorship on the patent, the assignment of rights in the patent and pending patent applications to Nanogen, an injunction preventing disclosure of trade secrets, damages for trade secret misappropriation and the imposition of a constructive trust. F-31 On September 30, 2002, CombiMatrix Corporation and Dr. Donald Montgomery entered into a settlement agreement with Nanogen to settle all pending litigation between the parties. Pursuant to the terms of the settlement agreement, Nanogen dismissed with prejudice its lawsuit against CombiMatrix Corporation and Dr. Montgomery. In return, CombiMatrix Corporation agreed to pay Nanogen $500,000 within 30 days of the settlement and an additional $500,000, which was paid in September 2003. CombiMatrix Corporation also agreed to make quarterly payments to Nanogen equal to 12.5% of payments to CombiMatrix Corporation from sales of products developed by CombiMatrix Corporation and its affiliates and based on the patents that had been in dispute in the litigation, up to an annual maximum of $1,500,000. The minimum quarterly payments under the settlement agreement will be $37,500 per quarter for the period from October 1, 2003 through October 1, 2004, and $25,000 per quarter thereafter until the patents expire in 2018. Also, pursuant to the settlement agreement, CombiMatrix Corporation issued to Nanogen 4,016,346 shares, or 17.5% of its outstanding shares post-issuance, subject to an anti-dilution provision related to the exercise of CombiMatrix Corporation options and warrants that were outstanding on the effective date of the agreement, for a period of up to three years. The issuance of the CombiMatrix Corporation common shares in settlement of the litigation with Nanogen was accounted for as a nonmonetary transaction. Accordingly, CombiMatrix Corporation recorded a non-cash litigation settlement charge in the consolidated statements of operations for the year ended December 31, 2002 of approximately $17,471,000, which was based on the fair value of the CombiMatrix Corporation common shares issued to Nanogen. Management was responsible for determining the fair value of the common shares issued to Nanogen on the settlement date and considered a number of factors, including reference to an independent third-party valuation. Management utilized an income approach to estimate the value of the common shares issued, based on the present value of CombiMatrix Corporation's future estimated cash flows. Future estimated cash flows included management's estimates of revenues, cost of sales, research and development expenses, sales and marketing expenses, general and administrative expenses, the anticipated effect of income taxes, and required returns on working capital, fixed assets and other assets necessary to support the generation of these cash flows. Future estimated cash flows were discounted to the present value using a discount rate of 25%, which reflected a required rate of return, comprised of an estimated weighted-average cost of capital, which was further increased to reflect the risk profile of the company's business. Total legal settlement charges recorded in the consolidated statement of operations for the year ended December 31, 2002 include the fair value of the common shares issued to Nanogen in the amount of $17,471,000 and a charge in the amount of $1,000,000 related to the cash payments due to Nanogen discussed above. During the year ended December 31, 2004, the CombiMatrix group recorded a net non-cash charge totaling $812,000 in connection with the anti-dilution provisions of the settlement agreement. The non-cash charge reflects management's estimate of the fair value of AR-CombiMatrix stock issued to Nanogen, Inc. as a result of certain options and warrants exercised during 2004 and the fair value of AR-CombiMatrix stock potentially issuable to Nanogen, Inc. as of December 31, 2004. The liability is adjusted at each balance sheet date for changes in the market value of the AR-CombiMatrix stock and is reflected as a long-term liability until settled in equity. The anti-dilution provisions of the settlement agreement expire in September 2005. PATENT ENFORCEMENT LITIGATION SOUNDVIEW TECHNOLOGIES In September 2002, the United States District Court for the District of Connecticut granted a motion for summary judgment filed by the defendants in Soundview Technologies pending patent infringement and antitrust lawsuit against Sony Corporation of America, the Consumer Electronics Manufacturers Association and the Electronics Industries Alliance d/b/a Consumer Electronics Association in the United States District Court for the Eastern District of Virginia (filed on April 5, 2000), alleging that television sets utilizing certain content blocking technology (commonly known as the "V-chip") and sold in the United States infringe Soundview Technologies' U.S. Patent No. 4,554,584. In granting the motion, the court ruled that the defendants have not infringed on Soundview Technologies' patent. In September 2003, a motion for summary judgment filed by the remaining defendants was granted by the United States District Court for the District of Connecticut on Soundview Technologies' anti-trust claims due to the Court's previous ruling of non-infringement as described above. In August 2004, the U.S. Court of Appeals for the Federal Circuit affirmed the September 2002 U.S. District Court for the District of Connecticut ruling that the remaining television manufacturers named in the Acacia Technologies group's V-chip patent infringement lawsuit do not infringe the Acacia Technologies group's V-chip patent. As a result of the ruling, the Acacia Technologies group recorded an impairment charge of $1,616,000 in connection with the write-off of goodwill related to the V-chip. In addition, as a result of the conclusion of the V-chip patent litigation, the Acacia Technologies group recognized $1,500,000 of previously deferred V-chip license fee revenues and $668,000 of previously deferred V-chip related legal costs in the third quarter of 2004. The remaining Non-Soundview parties have a motion pending before the United States District Court for the District of Connecticut seeking reimbursement of certain attorney's fees. Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on our financial position, results of operations or cash flows. F-32 The final ruling in the V-chip litigation has no impact on the revenues that we have recognized to date from licenseesIndemnifications

COMBIMATRIX GROUP (A DIVISION OF ACACIA RESEARCH CORPORATION) NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF BUSINESS Acacia Research Corporation is comprised of two separate divisions: the CombiMatrix group and the Acacia Technologies group (the "groups"). The CombiMatrix group, a division of Acacia Research Corporation, is comprised of Acacia Research Corporation's wholly owned subsidiary, CombiMatrix Corporation and CombiMatrix Corporation's wholly owned subsidiary, CombiMatrix K.K. The CombiMatrix group is seeking to become a broadly diversified biotechnology company, through the development of proprietary technologies and products in the areas of drug development, genetic analysis, nanotechnology research, defense and homeland security markets, as well as other potential markets where its products could be utilized. Among the technologies being developed by the CombiMatrix group are a platform technology to rapidly produce customizable arrays, which are semiconductor-based tools for use in identifying and determining the roles of genes, gene mutations and proteins. This technology has a wide range of potential applications in the areas of genomics, proteomics, biosensors, drug discovery, drug development, diagnostics, combinatorial chemistry, material sciences and nanotechnology. Other technologies include proprietary molecular synthesis and screening methods for the discovery of potential new drugs. CombiMatrix K.K., a wholly owned Japanese corporation located in Tokyo, is exploring opportunities for CombiMatrix Corporation's array system with pharmaceutical and biotechnology companies in the Asian market. LIQUIDITY AND RISKS The CombiMatrix group is deploying new and unproven technologies and continues to develop its commercial products. The CombiMatrix group has several ongoing long-term development projects that involve experimental technology and may require several years and substantial expenditures to complete. Management believes that existing cash and cash equivalents and short-term investments are adequate to fund operations through the next twelve months. However, the ability to meet business objectives is dependent upon the CombiMatrix group's ability to raise additional financing, substantiate its technology and ultimately to fund itself from continuing operations. There can be no assurance that such funding will be available at acceptable terms or at all. The CombiMatrix group's business operations are also subject to certain risks and uncertainties, including: o market acceptance of products and services; o technological advances that may make its products and services obsolete or less competitive; o increases in operating costs, including costs for supplies, personnel and equipment; o the availability and cost of capital; o general economic conditions; and o governmental regulation that may restrict its business. The CombiMatrix group has historically been substantially dependent on its existing arrangements with strategic partners including Roche Diagnostics GmbH ("Roche"), and has relied upon payments by Roche and other partners for a majority of its future revenues. The CombiMatrix group intends to enter into additional strategic partnerships to develop and commercialize future products. However, there can be no assurance that the CombiMatrix group will be able to implement its future plans. Failure by management to achieve its plans would have a material adverse effect on the CombiMatrix group's ability to achieve its intended business objectives. The CombiMatrix group's success also depends on its ability to protect its intellectual property. The CombiMatrix group's business depends on issued and pending patents, and the loss of any patents or the group's failure to secure the issuance of patents covering elements of its business processes would materially harm its business and financial condition. The patents covering the CombiMatrix group's core technology begin to expire January 5, 2018. F-48 RECAPITALIZATION TRANSACTION On December 11, 2002, Acacia Research Corporation's stockholders voted in favor of a recapitalization transaction, which became effective on December 13, 2002, whereby Acacia Research Corporation created two new classes of common stock called Acacia Research-CombiMatrix stock ("AR-CombiMatrix stock") and Acacia Research-Acacia Technologies stock ("AR-Acacia Technologies stock"), and divided the existing Acacia Research Corporation common stock into shares of the two new classes of common stock. AR-CombiMatrix stock is intended to2007, presented below, reflect separately the performance of Acacia Research Corporation's CombiMatrix group. AR-Acacia Technologies stock is intended to reflect separately the performance of Acacia Research Corporation's Acacia Technologies group. Although the AR-CombiMatrix stock and the AR-Acacia Technologies stock are intended to reflect the performance of Acacia Research Corporation's different business groups, they are both classes of common stock of Acacia Research Corporation and are not stock issued by the respective groups. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION. AR-CombiMatrix stock is intended to reflect the separate performance of the respective division of Acacia Research Corporation. The CombiMatrix group is not a separate legal entity. Holders of AR-CombiMatrix stock are stockholders of Acacia Research Corporation. As a result, holders of AR-CombiMatrix stock are subject to all of the risks of an investment in Acacia Research Corporation and all of its businesses, assets and liabilities. The assets Acacia Research Corporation attributes to the CombiMatrix group could be subject to the liabilities of the Acacia Technologies group. The CombiMatrix group financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, and taken together with the Acacia Technologies group financial statements, comprise all the accounts included in the corresponding consolidated financial statements of Acacia Research Corporation. The financial statements of CombiMatrix group reflect the financial condition, results of operations, and cash flows of the businesses included therein. The financial statements of the CombiMatrix group include the accounts or assets of Acacia Research Corporation specifically attributed to the CombiMatrix group and were prepared using amounts included in Acacia Research Corporation's consolidated financial statements. Minority interests represent participation of other stockholders in the allocated net assets and in the division earnings and losses of the CombiMatrix group and are reflected in the caption minority interests in CombiMatrix group's financial statements. Minority interests adjust CombiMatrix group's net results of operations to reflect only CombiMatrix group's share of the division earnings or losses of non-wholly owned investees of Acacia Research Corporation that have been attributed to the CombiMatrix group. Financial effects arising from one group that affect Acacia Research Corporation's results of operations or financial condition could, if significant, affect the results of operations or financial condition of the other group and the market price of the class of common stock relating to the other group. Any division net losses of thefor CombiMatrix group or the Acacia Technologies group and dividends or distributions on, or repurchases of, AR-CombiMatrix stock or AR-Acacia Technologies stock or repurchases of preferred stock of Acacia Research Corporation will reduce the assets of Acacia Research Corporation legally available for payment of dividends on AR-CombiMatrix stock or AR-Acacia Technologies stock. Refer to Note 2 to the Acacia Research Corporationas discontinued operations. The unaudited consolidated financial statements included elsewhere herein for the Acacia Research Corporation principles of consolidation, the management allocation policies, treasury and cash management policies, asset and liability attribution policies, corporate, general and administrative services and facilities allocation policies and federal and state income tax allocation policies, utilized in the preparation of the separate CombiMatrix group financial statements. REVENUE RECOGNITION. The CombiMatrix group recognizes revenue in accordance with Staff Accounting Bulletin No. 104, "Revenue Recognition" ("SAB No. 104") and related authoritative pronouncements. Revenues from multiple-element arrangements are accounted for in accordance with Emerging Issues Task Force ("EITF") Issue 00-21, "Revenue Arrangements with Multiple Deliverables." Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been performed pursuant to the terms of the license agreement, (iii) amounts are fixed or determinable and (iv) collectibility of amounts is reasonably assured. F-49 Revenues from multiple-element arrangements involving license fees, up-front payments and milestone payments, which are received and/or billable by us in connection with other rights and services that represent continuing obligations of ours, are deferred until all of the elements have been delivered or until the CombiMatrix group has established objective and verifiable evidence of the fair value of the undelivered elements. Revenues from government grants and contracts are recognized in accordance with Accounting Research Bulletin ("ARB") No. 43, "Government Contracts," and related pronouncements. Accordingly, revenues are recognized under the percentage-of-completion method of accounting, using the cost-to-cost approach to measure completeness at each reporting period. Under the percentage-of-completion method of accounting, contract revenues and expenses are recognized in the period that work is performed based on the percentage of actual incurred costs to estimated total contract costs. Actual contract costs and cost estimates include direct charges for labor and materials and indirect charges for labor, overhead and certain general and administrative charges. Contract change orders and claims are included when they can be reliably estimated and are considered probable. For contracts that extend over a one-year period, revisions in contract cost estimates, if they occur, have the effect of adjusting current period earnings applicable to performance in prior periods. Should current contract estimates indicate an overall future loss to be incurred, a provision is made for the total anticipated loss in the current period. Revenue from the sale of products and services, including shipping and handling fees, are recognized when delivery has occurred or services have been rendered. Deferred revenues arise from payments received in advance of the culmination of the earnings process. Deferred revenues expected to be recognized within the next twelve months are classified within current liabilities. Deferred revenues will be recognized as revenue in future periods when the applicable revenue recognition criteria as described above are met. CASH AND CASH EQUIVALENTS. The CombiMatrix group considers all highly liquid, short-term investments with original maturities of three months or less when purchased to be cash equivalents. SHORT-TERM INVESTMENTS. The CombiMatrix group's short-term investments are held in a variety of interest bearing instruments including high-grade corporate bonds, money market accounts and other high-credit quality marketable securities. Investments in securities with original maturities of greater than three months and less than one year are classified as short-term investments. Investments are classified in accordance with the provisions of Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS No. 115"). Investments are classified as available-for-sale, which are reported at fair value with related unrealized gains and losses in the value of such securities recorded as a component of allocated net worth until realized. The fair value of the CombiMatrix group's investments is determined by quoted market prices. Realized and unrealized gains and losses are recorded based on the specific identification method. For investments classified as available-for-sale, unrealized losses that are other than temporary are recognized in division net loss. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income (expense). Interest and dividends on all securities are included in interest income. CONCENTRATION OF CREDIT RISKS. Financial instruments that potentially subject the CombiMatrix group to concentrations of credit risk are cash equivalents and short-term investments. The CombiMatrix group places its cash equivalents and short-term investments primarily in investment grade, short-term debt instruments. Cash equivalents are invested in deposits with certain financial institutions and may, at times, exceed federally insured limits. The CombiMatrix group has not experienced any significant losses on its deposits of cash and cash equivalents. Research and development contract revenues recognized by the CombiMatrix group for the year ended December 31, 2004 relate to its research and development agreement with Roche. Government contract revenues recognized by the CombiMatrix group for the year ended December 31, 2004 relate to its two-year, F-50 $5.9 million contract with the Department of Defense awarded in March 2004. At December 31, 2004, accounts receivable included $248,000 due from the Department of Defense. In 2004, 2003 and 2002, 45%, 100% and 38% of the CombiMatrix group's array product and service sales were recorded by CombiMatrix K.K. Substantially all of the components and raw materials used in the manufacture of the CombiMatrix group's products, including semiconductors and reagents, are currently provided from a limited number of sources or in some cases from a single source. Although the CombiMatrix group believes that alternative sources for those components and raw materials are available, any supply interruption in a sole-sourced component or raw material might result in up to a several-month production delay and materially harm the CombiMatrix group's ability to manufacture products until a new source of supply, if any, could be located and qualified. The CombiMatrix group utilizes non-standard semiconductor manufacturing processes to fabricate the electrode array that is a key aspect of the array structure. Although the CombiMatrix group has a supply agreement in place with a semiconductor wafer manufacturer to ensure availability of the raw materials, it does not guarantee a permanent supply. INVENTORY. Inventory, which consists primarily of raw materials to be used in the production of the CombiMatrix group's array products, is stated at the lower of cost or market using the first-in, first-out method. PROPERTY AND EQUIPMENT. Property and equipment is recorded at cost. Additions and improvements that increase the value or extend the life of an asset are capitalized. Maintenance and repairs are expensed as incurred. Disposals are removed at cost less accumulated depreciation or amortization and any gain or loss from disposition is reflected in the statement of operations in the period of disposition. Depreciation is computed on a straight-line basis over the following estimated useful lives of the assets: Machine shop and laboratory equipment............ 3 to 5 years Furniture and fixtures........................... 5 to 7 years Computer hardware and software................... 3 years Leasehold improvements........................... Lesser of lease term or useful life of improvement Construction in progress includes direct costs incurred related to internally constructed assets which are depreciated once the asset is placed into service. Certain leasehold improvements, furniture and equipment held under capital leases are classified as property and equipment and are amortized over their useful lives using the straight-line method. Lease amortization is included in depreciation expense. ORGANIZATION COSTS. Costs of start-up activities, including organization costs, are expensed as incurred. PATENTS AND GOODWILL. Goodwill and identifiable intangibles, including patents, are recorded when the consideration paid for acquisitions exceeds the fair value of the net tangible assets acquired. Patents, once issued or purchased, are amortized on the straight-line method over their economic remaining useful lives, ranging from seven to twenty years. Goodwill is not amortized. IMPAIRMENT OF LONG-LIVED ASSETS AND GOODWILL. Long-lived assets and intangible assets are reviewed for potential impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset's carrying value over its fair value is recorded. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. Goodwill is evaluated for impairment in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets" ("SFAS No. 142") and is subject to a periodic review for potential impairment at a reporting unit level. Reviews for potential impairment must occur at least annually and may be performed earlier, if circumstances indicate that an impairment may have occurred. The CombiMatrix group has elected to perform its annual tests for indications of goodwill impairment as of December 31 of each year. The CombiMatrix group has one reporting unit. The fair value of the CombiMatrix group reporting unit is estimated using discounted cash flow analysis and by reference to quoted market prices of AR-CombiMatrix stock. F-51 SFAS No. 142 requires the CombiMatrix group to compare the fair value of its reporting unit to its carrying amount on an annual basis to determine if there is potential goodwill impairment. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the fair value of the goodwill within the reporting unit is less than its carrying value. There can be no assurance that future goodwill impairment tests will not result in a charge to earnings. FAIR VALUE OF FINANCIAL INSTRUMENTS. The carrying value of cash and cash equivalents, accounts receivables, accounts payable and accrued expenses approximate fair value due to their short-term maturity. FOREIGN CURRENCY TRANSLATION. The functional currency of CombiMatrix K.K. is the local currency (Japanese Yen). Foreign currency translation is reported pursuant to SFAS No. 52, "Foreign Currency Translation" ("SFAS No. 52"). Assets and liabilities recorded in foreign currencies are translated at the exchange rate on the balance sheet date. Translation adjustments resulting from this process are charged or credited to allocated net worth. Revenue and expenses are translated at average rates of exchange prevailing during the year. Foreign currency transactions gains and losses were insignificantdata for the years ended December 31, 2004, 2003 and 2002. STOCK-BASED COMPENSATION. Refer to Note 2 to the Acacia Research Corporation consolidated financial statements included elsewhere herein. Stock option and related option plan information is omitted from the CombiMatrix group footnotes because AR-CombiMatrix stock is part of the capital structure of Acacia Research Corporation. The CombiMatrix group is not a separate legal entity. Holders of AR-CombiMatrix stock continue to be stockholders of Acacia Research Corporation. This presentation reflects the fact that the CombiMatrix group does not have legally issued common or preferred stock, nor are warrant issuances or employee stock transactions legal transactions of the CombiMatrix group. Refer to the Acacia Research Corporation consolidated financial statements for disclosures regarding Acacia Research Corporation's stock option plans. RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses consist of costs incurred for direct and overhead-related research expenses and are expensed as incurred. Costs to acquire technologies which are utilized in research and development and which have no alternative future use are expensed when incurred. Costs related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. Software developed for use in the CombiMatrix group's products is expensed as incurred until both (i) technological feasibility for the software has been established and (ii) all research and development activities for the other components of the system have been completed. Management believes these criteria are met after the CombiMatrix group has received evaluations from third-party test sites and completed any resulting modifications to the products. Expenditures to date have been classified as research and development expense. ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT. The value assigned to acquired in-process research and development ("IPR&D") is determined by identifying acquired specific in-process research and development projects that would be continued and for which (a) technological feasibility has not been established at the acquisition date, (b) there is no alternative future use and (c) the fair value is estimable with reasonable reliability, upon consummation of a business combination. ADVERTISING. Costs associated with marketing and advertising of the CombiMatrix group's products and services are expensed as incurred. For the years ended December 31, 2004, 2003 and 2002, marketing and advertising expenses incurred by the CombiMatrix group were $314,000, $26,000 and $62,000, respectively. INCOME TAXES. Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the CombiMatrix group's financial statements or tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized. SEGMENTS. The CombiMatrix group follows SFAS No. 131, "Disclosure about Segments of an Enterprise and Related Information" ("SFAS No. 131"), which establishes annual and interim reporting standards for an enterprise's operating segments and related disclosures about its products, services, geographic areas and major customers. Management has determined that the CombiMatrix group operates in one segment. F-52 USE OF ESTIMATES. The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the combined financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. EARNINGS PER SHARE. Earnings per share information is omitted from the CombiMatrix group statements of operations because AR-CombiMatrix stock is part of the capital structure of Acacia Research Corporation. The CombiMatrix group is not a separate legal entity. Holders of AR-CombiMatrix stock continue to be stockholders of Acacia Research Corporation. This presentation reflects the fact that the CombiMatrix group does not have legally issued common or preferred stock, nor are warrant issuances or employee stock transactions legal transactions of the CombiMatrix group. Refer to the Acacia Research Corporation consolidated financial statements for earnings per share information for Acacia Research Corporation's classes of stock. CERTAIN RISKS AND UNCERTAINTIES. The CombiMatrix group's products and services will be concentrated in a highly competitive market that is characterized by rapid technological advances, frequent changes in customer requirements and evolving regulatory requirements and industry standards. Failure to anticipate or respond adequately to technological advances, changes in customer requirements, changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of planned products or services, could have a material adverse effect on the CombiMatrix group's business and operating results.

("Leuchemix"), a private drug development firm, which is developing several compounds for the treatment of leukemia and other cancers. In accordance with the terms of the purchase agreement, the CombiMatrix group will purchase 3,137,500 shares of Series A Preferred Stock of Leuchemix for a total purchase price of $4,000,000. The ownership interest will be acquired and paid for quarterly, beginning with the fourth quarter of 2004 and continuing through the third quarter of 2006. As of December 31, 2004, the CombiMatrix group has initially invested $250,000 for a 3% interest in the total outstanding voting securities of Leuchemix. In accordance with the terms of the purchase agreement, CombiMatrix Corporation's CEO was named a director of Leuchemix. Although the CombiMatrix group's investment in Leuchemix only represented approximately 3% of Leuchemix's total outstanding voting securities as of the Investment Date, the CombiMatrix group's investment is being accounted for under the equity method as the CombiMatrix group has the ability to exercise significant influence over Leuchemix, primarily due to CombiMatrix Corporation's representation on Leuchemix's board of directors. The CombiMatrix group's 3% interest in the equity in loss of Leuchemix, including its share of the amortization expense related to the excess purchase consideration over the book value of Leuchemix was not material for the year-ended December 31, 2004. Future investments in Leuchemix will be accounted for as step acquisitions. Summary financial information for Leuchemix was not significant as of December 31, 2004. 6. INTANGIBLES The CombiMatrix group has $19,424,000 of goodwill at December 31, 2004 and 2003. The CombiMatrix group's only identifiable intangible assets are patents, which are being amortized over an economic useful life of approximately 11 years. The gross carrying amounts and accumulated amortization related to acquired intangible assets, all related to patents, as of December 31, 2004 and 2003, are as follows (in thousands): 2004 2003 ----------- ----------- Gross carrying amount - patents ..... $ 12,095 $ 12,095 Accumulated amortization ............ (3,074) (1,978) ----------- ----------- Patents, net ........................ $ 9,021 $ 10,117 =========== =========== Aggregate patent amortization expense was $1,096,000, $1,095,000 and $399,000 in 2004, 2003 and 2002, respectively. Annual aggregate amortization expense for each of the next five years through December 31, 2009 is estimated to be $1,095,000 per year. Refer to Note 12, "Step Acquisitions Allocated to the CombiMatrix Group," for additions to intangibles and goodwill during 2004 and 2003. F-54 7.

At December 31, 2004, the CombiMatrix group has deferred tax assets totaling approximately $40,794,000, which are fully offset by a valuation allowance due to management's determination that the criteria for asset recognition have not been met. Acacia Research Corporation files a consolidated federal income tax return that includes the Acacia Technologies group (excluding discontinued operations) and the CombiMatrix group. At December 31, 2004, the CombiMatrix group had federal net operating loss carryforwards of approximately $90,131,000, which will begin to expire in 2012 through 2024. In addition, the CombiMatrix group has tax credit carryforwards of approximately $2,869,000. Utilization of net operating loss carryforwards and tax credit carryforwards are subject to the "change of ownership" provisions under Section 382 of the Internal Revenue Code. The amount of such limitations has not been determined. Had the CombiMatrix group filed separate tax returns, the benefit for income taxes and division net loss would not have differed from the amounts reported in the CombiMatrix group's statements of operations for the years ended December 31, 2004, 2003, and 2002. F-56 9. COMMITMENTS AND CONTINGENCIES OPERATING LEASES In October 2000, CombiMatrix Corporation entered into a non-cancelable operating lease for office space. A security deposit in the form of a $783,000 letter of credit was issued November 1, 2000, which was increased to $1,200,000 during 2001 and to $1,500,000 during 2002. Future minimum operating lease payments as of December 31, 2004 are as follows (in thousands): YEAR ---- 2005 ....................................... $ 1,923 2006 ....................................... 1,836 2007 ....................................... 1,937 2008 ....................................... 1,615 Thereafter ................................. - ----------- Total minimum lease payments ............... $ 7,311 =========== Rent expense for the years ended December 31, 2004, 2003 and 2002 was $1,933,000, $2,006,000 and $1,618,000, respectively. COLLABORATIVE AND RESEARCH AGREEMENTS In July 2001, CombiMatrix Corporation entered into a non-exclusive worldwide license, supply, research and development agreement with Roche. Under the terms of the agreement, Roche will purchase, use and resell CombiMatrix Corporation's array and related technologies for production of customizable arrays. Additionally, CombiMatrix Corporation and Roche will develop a platform technology, providing a range of standardized arrays for use in research applications. The agreement has a 15-year term and provides for minimum payments by Roche to CombiMatrix Corporation over the first three years, including payments upon the achievement of certain milestone and payments for products, royalties and research and development projects. During 2003 and 2002, the CombiMatrix group's research and development activities were driven primarily by ongoing performance obligations under the product commercialization phase of its license and research and development agreements with Roche. These activities include costs associated with direct labor, supplies and materials, development of prototype arrays and instruments and the use of outside consultants for certain engineering efforts. As previously discussed in Note 7, the CombiMatrix group completed all phases of its research and development agreement with Roche in March 2004. As previously disclosed in Note 5, the CombiMatrix group has entered into an agreement with Leuchemix to purchase a total of $4,000,000 of Series A Preferred Stock of Leuchemix over a two-year period. Future quarterly cash investments by the CombiMatrix group in Leuchemix are $1,600,000 in 2005 and $2,150,000 in 2006. In March 2004, the CombiMatrix group was awarded a two-year, $5.9 million contract with the Department of Defense to further the development of the CombiMatrix group's array technology for the detection of biological threat agents. Under the terms of the contract, the CombiMatrix group will perform research and development activities as described under the contract and will be reimbursed on a periodic basis for actual costs incurred to perform its obligations, plus a fixed fee, of up to $5.9 million. Based on actual costs incurred through December 31, 2004, the CombiMatrix group expects to incur approximately $2.2 million and $819,000 in research and development costs during 2005 and 2006, respectively, to complete its obligations to the Department of Defense under this contract. As of December 31, 2004, the biowarfare detection contract with the Department of Defense was approximately 34% complete. F-57 In July 2004, the CombiMatrix group and collaborator irsiCaixa Foundation ("IRSI") entered into a three-year research, development and licensing agreement to develop certain siRNA compounds for pre-clinical drug development against the HIV virus. Pursuant to the terms of the agreement, the CombiMatrix group will make quarterly research and development funding payments to IRSI totaling $450,000 over a period of three years, which began in July 2004. In addition, the CombiMatrix group may make future contingent milestone payments for compounds that are developed, in accordance with the terms of the agreement. In consideration for receiving rights to commercialize the compounds under development, the CombiMatrix group will pay royalties to IRSI based on commercial sales of related products, in accordance with the agreement. HUMAN RESOURCES The CombiMatrix group provides certain severance benefits such that if an executive who is a vice president or higher is terminated for other than cause, death or disability, the executive will receive payments equal to three months' base salary and other medical and dental benefits on a bi-weekly basis over a three-month period. If termination occurs as a result of a change in control transaction, these benefits will be extended by three months. The CombiMatrix group also offers a general severance plan providing all employees with certain benefits upon their termination of employment due to lack of work. Under this plan, terminated employees will be provided with either four-weeks notice or four-weeks' salary in lieu of notice, and paid a lump-sum amount based on the employee's length of service, plus accrued benefits. The terminated employees will also be provided continuing medical and dental benefits, as well as continuation of life insurance, for a period ranging from two to 26 weeks subsequent to the date of termination, depending upon the employee's length of service. LITIGATION On November 28, 2000, Nanogen, Inc. ("Nanogen") filed suit against CombiMatrix Corporation and Dr. Donald Montgomery, an officer, director and stockholder of CombiMatrix Corporation. The Nanogen suit alleged, among other things, that CombiMatrix Corporation's issued patent and certain pending patent applications, trade secrets and related technologies that were inappropriately obtained by CombiMatrix Corporation and that Nanogen was the legal owner of the patents, trade secrets and related technologies. The suit sought, among other things, correction of inventorship on CombiMatrix Corporation's issued patent, the assignment of rights in the issued patent and pending patent applications to Nanogen, an injunction preventing disclosure of trade secrets, damages for trade secret misappropriation and the imposition of a constructive trust. On September 30, 2002, CombiMatrix Corporation and Dr. Donald Montgomery entered into a settlement agreement with Nanogen, Inc. to settle all pending litigation between the parties. Pursuant to the terms of the settlement agreement, CombiMatrix Corporation agreed to pay Nanogen $500,000 within 30 days of the settlement, which was paid, and an additional $500,000 within one year of the settlement (paid in September 2003). CombiMatrix Corporation also agreed to make quarterly payments to Nanogen equal to 12.5% of total sales of products developed by CombiMatrix Corporation and its affiliates and based on the patents that had been in dispute in the litigation, up to an annual maximum of $1,500,000. The minimum quarterly payments under the settlement agreement will be $37,500 per quarter for the period from October 1, 2003 through October 1, 2004, and $25,000 per quarter thereafter until the patents expire. Also, pursuant to the settlement agreement, CombiMatrix Corporation issued to Nanogen 4,016,346 shares, or 17.5% of its outstanding shares post-issuance, subject to an anti-dilution provision related to the exercise of CombiMatrix Corporation options and warrants that were outstanding on the effective date of the agreement, for a period of up to three years. The issuance of the CombiMatrix Corporation common shares in settlement of the litigation with Nanogen was accounted for as a nonmonetary transaction. Accordingly, CombiMatrix Corporation recorded a non-cash litigation settlement charge in the consolidated statements of operations for the year ended December 31, 2002 of approximately $17,471,000, which was based on the fair value of the CombiMatrix Corporation common shares issued to Nanogen. Management was responsible for determining the fair value of the common shares issued to Nanogen on the settlement date and considered a number of factors, including reference to an independent third-party valuation. Management utilized an income approach to estimate the value of the common shares issued, based on the present value of CombiMatrix Corporation's future estimated cash flows. Future estimated cash flows included management's estimates of revenues, cost of sales, research and development expenses, sales and marketing expenses, general and administrative expenses, the anticipated effect of income taxes, and required returns on working capital, fixed assets and other assets necessary to support the generation of these cash flows. Future estimated cash flows were discounted to the present value using a discount rate of 25%, which reflected a required rate of return, comprised of an estimated weighted-average cost of capital, which was further increased to reflect the risk profile of the company's business. F-58 Total legal settlement charges recorded in the CombiMatrix group statement of operations for the year ended December 31, 2002 include the fair value of the common shares issued to Nanogen in the amount of $17,471,000 and a charge in the amount of $1,000,000 related to the cash payments due to Nanogen discussed above. During the year ended December 31, 2004, the CombiMatrix group recorded a net non-cash charge totaling $812,000 in connection with the anti-dilution provisions of the settlement agreement. The non-cash charge reflects management's estimate of the fair value of AR-CombiMatrix stock issued to Nanogen, Inc. as a result of certain options and warrants exercised during 2004 and the fair value of AR-CombiMatrix stock potentially issuable to Nanogen, Inc. as of December 31, 2004. The liability is adjusted at each balance sheet date for changes in the market value of the AR-CombiMatrix stock and is reflected as a long-term liability until settled in equity. The anti-dilution provisions of the settlement agreement expire in September 2005. The CombiMatrix group is subject to other claims and legal actions that arise in the ordinary course of business. Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on CombiMatrix group's financial position, results of operations or cash flows. 10. RETIREMENT SAVINGS PLAN The CombiMatrix group has an employee savings and retirement plan under section 401(k) of the Internal Revenue Code (the "Plan"). The Plan is a defined contribution plan in which eligible employees may elect to have a percentage of their compensation contributed to the Plan, subject to certain guidelines issued by the Internal Revenue Service. The CombiMatrix group may contribute to the Plan at the discretion of Acacia Research Corporation's board of directors. There were no contributions made by the CombiMatrix group during the years ended December 31, 2004, 2003 and 2002. 11. ALLOCATED NET WORTH The CombiMatrix group's statements of allocated net worth present the equity transactions of Acacia Research Corporation, which are attributed to the CombiMatrix group as "Net assets attributed to the CombiMatrix group." This presentation reflects the fact that the CombiMatrix group does not have legally issued common or preferred stock, nor are warrant issuances or employee stock option transactions legal transactions of the CombiMatrix group. Presented below is a detail of the equity transactions of Acacia Research Corporation which relate to the businesses of the CombiMatrix group and which therefore comprise the balances reflected in the group's net assets attributed to CombiMatrix group (in thousands): COMBIMATRIX GROUP ------------- 2002 Allocated corporate charges ............................................................... $ 1,032 Stock options exercised ................................................................... 29 Change in capital due to issuance of stock by subsidiaries ................................

EQUITY FINANCINGS In April 2004, Acacia Research Corporation raised net proceeds of approximately $13,715,000 through the sale of 3,000,000 shares of Acacia Research - CombiMatrix common stock in a registered direct offering. The net proceeds from this offering were attributed to the CombiMatrix group. In May 2003, Acacia Research Corporation completed a private equity financing, raising gross proceeds of $5,247,000 through the issuance of 2,385,000 units. Each unit consists of one share of AR-CombiMatrix common stock and one-half five-year callable common stock purchase warrant. Each full common stock purchase warrant entitles the holder to purchase a share of AR-CombiMatrix stock at a price of $2.75 per share and is callable by Acacia Research Corporation once the daily average of the high and low prices of Acacia Research Corporation's AR-CombiMatrix stock on the Nasdaq SmallCap Market is equal to or above $4.50 for 20 consecutive trading days. Acacia Research Corporation issued an additional 31,502 shares of AR-CombiMatrix stock in lieu of cash payments in conjunction with the private placement for finder's fees. Net proceeds raised from the private equity financing of $4,862,000 have been attributed to the CombiMatrix group. WARRANTS During 2004 and 2003, proceeds of $2,093,000 and $450,000 were received from the issuance of 761,205 and 164,000 shares, respectively, of AR-CombiMatrix stock related to the exercise of certain warrants issued in connection with the May 2003 private equity financing described below. The proceeds from the warrants exercised were attributed to the CombiMatrix group. 12. STEP ACQUISITIONS ALLOCATED TO THE COMBIMATRIX GROUP On July 11, 2003, Acacia Research Corporation purchased the outstanding minority interests in its consolidated subsidiary CombiMatrix K.K. from Marubeni. Acacia Research Corporation issued 200,000 shares of its AR-CombiMatrix stock to Marubeni in exchange for Marubeni's 10% minority interests (120 shares) in CombiMatrix K.K. The transaction was accounted for as a step acquisition using the purchase method of accounting. The fair value of F-60 the AR-CombiMatrix stock issued in the transaction was based on the quoted market price of AR-CombiMatrix stock on the exchange date. The total purchase price of $450,000 was allocated to the fair value of assets acquired and liabilities assumed. The amount attributable to goodwill was $393,000. In April 2002, CombiMatrix Corporation purchased Acacia Research Corporation's majority interest in Advanced Material Sciences. CombiMatrix Corporation issued 180,982 shares of its common stock to Acacia Research Corporation in exchange for Acacia Research Corporation's 58% interest in Advanced Material Sciences. As a result of this transaction, CombiMatrix Corporation owned 87% of Advanced Material Sciences as of December 31, 2002, with the remaining interests owned by unaffiliated parties. The April 2002 transaction was accounted for using Acacia Research Corporation's basis in the net assets of Advanced Material Sciences and as a result, the CombiMatrix group's 2002 financial statements reflected the assets and liabilities of Advanced Material Sciences at historical cost. On July 2, 2003, Acacia Research Corporation increased its consolidated ownership interest in Advanced Material Sciences to 99% by acquiring 1,774,750 shares of Advanced Material Sciences common stock in exchange for 295,790 shares of AR-CombiMatrix stock. The transaction was accounted for as a step acquisition using the purchase method of accounting. The fair value of the Acacia Research shares issued in the transaction was based on the quoted market price of AR-CombiMatrix stock on the exchange date. The total purchase price of $769,000 was allocated to the fair value of assets acquired and liabilities assumed. The amount attributable to goodwill was $172,000. Acacia Research Corporation's interests in Advanced Material Sciences and CombiMatrix K.K. have been attributed to the CombiMatrix group. On December 13, 2002, Acacia Research Corporation increased its consolidated ownership interest in CombiMatrix Corporation from 48% to 100% by acquiring from existing stockholders of CombiMatrix Corporation 11,987,052 shares of CombiMatrix Corporation common stock in exchange for 11,987,052 shares of AR-CombiMatrix stock with a fair value of $46,007,000. The merger was designed to consolidate Acacia Research Corporation's ownership of CombiMatrix Corporation and permit Acacia Research Corporation to effectuate the recapitalization transaction described elsewhere herein, by creating the CombiMatrix group. The transaction was accounted for as a step acquisition using the purchase method of accounting. The fair value of the AR-CombiMatrix stock issued in the transaction was based on the quoted market price of AR-CombiMatrix stock averaged over a five-day period (from December 16, 2002, the first day of trading for the AR-CombiMatrix stock, through December 20, 2002). The following table summarizes the estimated fair values of the assets acquired and liabilities assumed and the allocation of the purchase price at the date of acquisition (in thousands): Acquisition costs: Exchange of AR-CombiMatrix stock for CombiMatrix Corporation common stock .................................................. $ 46,007 Acquisition expenses ............................................. 834 ----------- Total acquisition cost ........................................... $ 46,841 =========== Purchase price allocation: Fair value of 52% of CombiMatrix Corporation net tangible assets at December 13, 2002 ......... 8,313 Intangible assets acquired: Core technology/patent ....................................... 5,283 Acquired in-process research and development ................. 17,237 Goodwill (non-deductible for tax purposes) ................... 16,008 ----------- Total ............................................................ $ 46,841 ===========
F-61 The total purchase price of $46,841,000 was allocated to the fair value of assets acquired and liabilities assumed, including acquired IPR&D, as shown above. The amount attributable to CombiMatrix Corporation's core technology and related patents is being amortized using the straight-line method over the estimated economic useful life of 7 years. Amounts allocated to patents, IPR&D and goodwill have been attributed to the CombiMatrix group. In conjunction with the allocation of the purchase price, Acacia Research Corporation was required to adjust CombiMatrix Corporation's assets and liabilities to fair value. Deferred revenue, primarily consisting of milestone payments and other cash receipts from Roche and NASA, was reduced by $8,425,000 to reflect the fair value of the continuing obligation related to the 52% interest in CombiMatrix Corporation acquired by Acacia Research Corporation. The amount attributable to IPR&D projects (comprised of two projects: Genomics and Proteomics biological array systems) that had not yet reached technological feasibility and had no alternative future use of $17,237,000 was charged to expense on the acquisition date and is included in the accompanying statement of operations for the year ended December 31, 2002. Management was responsible for determining the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed, including IPR&D, at the date of acquisition. Management considered a number of factors, including reference to independent valuations. The in-process technologies were valued using a discounted cash flow model on a project-by-project basis, which estimated the cash flows expected to result from each project once it has reached technological feasibility. A discount rate consistent with the risks of each project was used to estimate the present value of future cash flows. In estimating future cash flows, management considered the contribution of its core technology (for which a United States patent was obtained in July 2000) that would be required for successful exploitation of purchased in-process technology, in order to value the core and in-process technologies discretely. As a result, future cash flows relating to each purchased IPR&D project were reduced in order to reflect the contribution of core technology to each IPR&D project. The cash flows from these projects attributable to core technology were then separately valued to determine the intangible asset value of purchased core technology. In determining the contribution of core technology to in-process projects, management used a profit split approach which considered the estimated profit split between a licensor and licensee of the core technology and management's assessment of how critical the core technology was to the IPR&D projects. The nature of the efforts to develop the purchased IPR&D into commercially viable products principally relates to the completion and/or acceleration of existing development programs. These efforts include testing current and alternative materials used in array design, testing of existing and alternative methods for array synthesis, developing prototype machinery (including operating software) to synthesize, hybridize and read individual arrays, and to perform numerous experiments, or assays, with actual target samples in order to determine customer protocols and procedures for using the CombiMatrix group's array system. Following is a brief description of the two IPR&D projects identified. Genomics Biological Array System: CombiMatrix Corporation's genomics biological array processor system is being developed to discretely immobilize sequences of DNA or RNA within individual test sites on a modified semiconductor chip coated with a three-dimensional layer of porous material. The system also includes proprietary hardware units and related software applications to be able to synthesize materials onto the chips, apply target samples of genetic materials and interpret the results. The value assigned to the genomics biological array system IPR&D project was $13,978,000. A risk-adjusted discount rate of 32% was applied to the project's estimated cash flows. Proteomics Biological Array System: CombiMatrix Corporation's proteomics biological array processor system is being developed to discretely immobilize proteins and other small molecules within individual test sites on a modified semiconductor chip in a similar fashion as described above for the genomics biological array system. The proteomics biological array system is used for detection and identification of bio-threat agents in CombiMatrix Corporation's biological and chemical threat agent detector development programs that are currently in process.

ACACIA TECHNOLOGIES GROUP (A DIVISION OF ACACIA RESEARCH CORPORATION) NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF BUSINESS Acacia Research Corporation's continuing operations are comprised of two separate divisions: the Acacia Technologies group and the CombiMatrix group (the "groups"). The Acacia Technologies group, a division of Acacia Research Corporation, is primarily comprised of Acacia Research Corporation's interests in three wholly owned subsidiaries: (1) Acacia Media Technologies Corporation, ("Acacia Media Technologies") a Delaware corporation, (2) Soundview Technologies, Inc., ("Soundview Technologies") a Delaware corporation, and (3) Acacia Internet Access Corporation, a Delaware corporation, and also includes all corporate assets, liabilities, and related transactions of Acacia Research Corporation attributed to the Acacia Research Corporation's intellectual property licensing business. The Acacia Technologies group develops, acquires, and licenses patented technologies. Including the impact of the January 28, 2005 acquisition of the assets of Global Patent Holdings, LLC ("Global Patent Holdings") as discussed at Note 13, the Acacia Technologies group controls 29 patent portfolios, which include 126 U.S. patents, and certain foreign counterparts, covering technologies used in a wide variety of industries including audio/video-on-demand, digital ad insertion, interactive television, broadcast equipment, data transmission, cache coherency, data file synchronization, data matrix bar codes, dynamic manufacturing models, product activation, encryption, image resolution and enhancement, scheduling software, interstitial Internet advertising, interactive simulation systems, peer to peer network communications, spreadsheet programs, endoscopic cameras, video noise reduction, and audio/video synchronization. LIQUIDITY AND RISKS The Acacia Technologies group believes that its cash and cash equivalent and short term investment balances, anticipated cash flow from operations and other external sources of available credit will be sufficient to meet its cash requirements through the next twelve months. To date, the Acacia Technologies group has relied primarily upon selling of Acacia Research Corporation equity securities and payments from V-chip licensees (primarily in 2001) and DMT(R) licensees (2003 to current) to generate the funds needed to finance the operations of the Acacia Technologies group. The V-chip patent expired in July 2003. The V-chip licensing program was concluded in August 2004 and the Acacia Technologies group does not expect to collect any additional V-chip related license fee revenues in future periods. The Acacia Technologies group began to commercially license its DMT technology in 2003, recognizing approximately $3.5 million in DMT license fee revenues to date, and intends to acquire and develop additional intellectual property. Acacia Global Acquisition Corporation's acquisition of the assets of Global Patent Holdings, LLC as discussed at Note 13, provides the Acacia Technologies group with ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts, and cover technologies used in a wide variety of industries. The acquisition expands and diversifies the Acacia Technologies group's revenue generating opportunities. However, there can be no assurance that the Acacia Technologies group will be able to implement its future plans. Failure by management to achieve its plans would have a material adverse effect on the Acacia Technologies group and on Acacia Research Corporation's ability to achieve its intended business objectives. The Acacia Technologies group's success also depends on its ability to protect its intellectual property. The Acacia Technologies group's business operations are subject to certain risks and uncertainties, including: F-69 o market acceptance of products and services; o technological advances that may make the Acacia Technologies group's technologies obsolete or less competitive; o increases in operating costs, including costs for supplies, personnel and equipment; o the availability and cost of capital; o general economic conditions; and o governmental regulation that may restrict the Acacia Technologies group's businesses. The Acacia Technologies group relies on its proprietary rights and their protection. Although reasonable efforts will be taken to protect the Acacia Technologies group's proprietary rights, the complexity of international trade secret, copyright, trademark and patent law, and common law, coupled with limited resources and the demands of quick delivery of technologies to market, create risk that these efforts will prove inadequate. Accordingly, if the Acacia Technologies group is unsuccessful with litigation to protect its intellectual property rights, the future revenues of the Acacia Technologies group could be adversely affected. The Acacia Technologies group's U.S. DMT patents expire in 2011 and its foreign DMT patents expire in 2012. RECAPITALIZATION TRANSACTION On December 11, 2002, Acacia Research Corporation's stockholders voted in favor of a recapitalization transaction, which became effective on December 13, 2002, whereby Acacia Research Corporation created two new classes of common stock called Acacia Research-CombiMatrix stock ("AR-CombiMatrix stock") and Acacia Research-Acacia Technologies stock ("AR-Acacia Technologies stock"), and divided the existing Acacia Research Corporation common stock into shares of the two new classes of common stock. AR-CombiMatrix stock is intended to reflect separately the performance of Acacia Research Corporation's CombiMatrix group. AR-Acacia Technologies stock is intended to reflect separately the performance of Acacia Research Corporation's Acacia Technologies group. Although the AR-CombiMatrix stock and the AR-Acacia Technologies stock are intended to reflect the performance of the different business groups, they are both classes of common stock of Acacia Research Corporation and are not stock issued by the respective groups. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION. AR-Acacia Technologies stock is intended to reflect the separate performance of the respective division of Acacia Research Corporation. The Acacia Technologies group is not a separate legal entity. Holders of AR-Acacia Technologies stock are stockholders of Acacia Research Corporation. As a result, holders of AR-Acacia Technologies stock are subject to all of the risks of an investment in Acacia Research Corporation and all of its businesses, assets and liabilities. The assets Acacia Research Corporation attributes to Acacia Technologies could be subject to the liabilities of the CombiMatrix group. The Acacia Technologies group financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, and taken together with the CombiMatrix group financial statements, comprise all the accounts included in the corresponding consolidated financial statements of Acacia Research Corporation. The financial statements of Acacia Technologies group reflect the financial condition, results of operations, and cash flows of the businesses included therein. The financial statements of the Acacia Technologies group include the accounts or assets of Acacia Research Corporation specifically attributed to the Acacia Technologies group and were prepared using amounts included in Acacia Research Corporation's consolidated financial statements. Minority interests represents participation of other stockholders in the allocated net assets and in the division earnings and losses of the Acacia Technologies group and is reflected in the caption minority interests in the Acacia Technologies group financial statements. Minority interests adjust the Acacia Technologies group's share of the division's earnings or loss of non-wholly owned subsidiaries of Acacia Research Corporation that have been attributed to the Acacia Technologies group. F-70 Financial effects arising from one group that affect Acacia Research Corporation's results of operations or financial condition could, if significant, affect the results of operations or financial condition of the other group and the market price of the class of common stock relating to the other group. Any division net losses of the CombiMatrix group or the Acacia Technologies group and dividends or distributions on, or repurchases of, AR-CombiMatrix stock or AR-Acacia Technologies stock or repurchases of preferred stock of Acacia Research Corporation will reduce the assets of Acacia Research Corporation legally available for payment of dividends on AR-CombiMatrix stock or AR-Acacia Technologies stock. Refer to Note 2 to the Acacia Research Corporation consolidated financial statements included elsewhere herein for the Acacia Research Corporation principles of consolidation, management allocation policies, treasury and cash management policies, asset and liability attribution policies, corporate, general and administrative services and facilities allocation policies and federal and state income tax allocation policies, utilized in the preparation of the separate Acacia Technologies group financial statements. REVISION IN THE CLASSIFICATION OF CERTAIN SECURITIES. In connection with the preparation of this report, the Acacia Technologies group concluded that it was appropriate to classify its auction rate municipal bonds and variable rate municipal demand notes as current investments. Previously, such investments had been classified as cash and cash equivalents. Accordingly, the Acacia Technologies group has revised its prior classification to report these securities as current investments in its Balance Sheet as of December 31, 2003. The Acacia Technologies group has also made corresponding adjustments to its Statement of Cash Flows

(8)Incorporated by reference to Acacia Research Corporation’s Quarterly Report on Form 10-Q for the period ended September 30, 2007.
(9)Incorporated by reference from Acacia Research Corporation’s Annual Report on Form 10-K for the year ended December 31, 2002, to reflect the gross purchases and sales of these securities as investing activities rather than as a component of cash and cash equivalents. This change in classification does not affect previously reported cash flows from operations or from financing activities in the Acacia Technologies group's previously reported Statements of Cash Flows, or its previously reported Statements of Income for any period. As of December 31, 2003, before this revision in classification, $7,750,000 of these current investments were classified as cash and cash equivalents on the Acacia Technologies group's Balance Sheet. For the fiscal year ended December 31, 2002, before this revision in classification, net cash used in investing activities related to these current investments of $7,750,000 were included in cash and cash equivalents in the Acacia Technologies group's Statement of Cash Flows. REVENUE RECOGNITION. Under the terms of the Acacia Technologies group's DMT license agreements, the Acacia Technologies group grants non-exclusive licenses for the use of its patented DMT technology. Pursuant to the terms of the DMT license agreements, once executed, the Acacia Technologies group has no further obligations with respect to the grant of the licenses. License fees paid to and recognized as revenue by the Acacia Technologies group are non-refundable. Revenue generated from license agreements are generally accrued and recognized as revenue in the period earned, provided that amounts are fixed or determinable and collectibility is reasonably assured. Certain license agreements provide for the calculation of license fees based on a licensee's actual quarterly sales or actual per unit activity, applied to a contractual royalty rate. Licensees that pay license fees on a quarterly basis generally report actual quarterly sales or actual per unit activity information and related quarterly license fees due to the Acacia Technologies group within 30 to 45 days after the end of the quarter in which such sales or activity takes place. Consequently, the Acacia Technologies group recognizes revenue from these licensing agreements on a three-month lag basis, in the quarter following the quarter of sales or per unit activity, provided amounts are fixed or determinable and collectibility is reasonably assured. The lag method described above allows for the receipt of licensee royalty reports prior to the recognition of revenue. Certain license agreements provide for the payment of a minimum upfront annual license fee at the inception of each annual license term. Minimum upfront annual license fees are generally determined based on a licensee's estimated annual sales or a licensee's base level of per unit activity. These minimum upfront annual license fee payments are deferred and amortized to revenue on a straight-line basis over the annual license term. To the extent actual annual royalties, determined and reported in accordance with the terms of the respective agreements, exceed the minimum upfront annual license fees paid, the additional royalties are recognized in revenue in the quarter following the quarter in which the base per unit activity was exceeded or the quarter following the annual license term, depending on the terms of the respective agreement, provided that amounts are fixed or determinable and collectibility is reasonably assured. F-71 License fee payments received by the Acacia Technologies group that do not meet the revenue recognition criteria described above are deferred until the revenue recognition criteria are met. The Acacia Technologies group assesses collection of accrued license fees based on a number of factors, including past transaction history and credit-worthiness. If it is determined that collection is not reasonably assured, the fee is recognized when collectibility becomes reasonably assured, assuming all other revenue recognition criteria have been met, which is generally upon receipt of cash. As a result of the Acacia Technologies group's licensing and any related intellectual property enforcement activities that the Acacia Technologies group chooses to conduct, The Acacia Technologies group may recognize royalty revenues that relate to prior period infringements by licensees. Differences between amounts initially recognized and amounts subsequently audited or reported as an adjustment to those amounts will be recognized in the period the adjustment is determined as a change in accounting estimate. CASH AND CASH EQUIVALENTS. The Acacia Technologies group considers all highly liquid, short-term investments with original maturities of three months or less when purchased to be cash equivalents. SHORT-TERM INVESTMENTS. The Acacia Technologies group's short-term investments are held in a variety of interest bearing instruments including high-grade corporate bonds, commercial paper, money market accounts, certificates of deposit and other high-credit quality marketable securities. Investments in securities with original maturities of greater than three months and less than one year are classified as short-term investments. Investments are classified into categories in accordance with the provisions of Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS No. 115"). At December 31, 2004 and 2003, all of the Acacia Technologies group's investments are classified as available-for-sale, which are reported at fair value with related unrealized gains and losses in the value of such securities recorded as a component of allocated net worth until realized. During 2002, certain of the Acacia Technologies group's investments were classified as trading securities. Realized and unrealized gains and losses in the value of trading securities are included in net income (loss) in the consolidated statements of operations and comprehensive loss. The fair value of the Acacia Technologies group's investments is primarily determined by quoted market prices. Realized and unrealized gains and losses are recorded based on the specific identification method. For investments classified as available-for-sale, unrealized losses that are other than temporary are recognized in division net income (loss). The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income (expense). Interest and dividends on all securities are included in interest income. At December 31, 2004 and 2003, the Acacia Technologies group held $11,900,000 and $7,750,000, respectively, of short-term investments, which consist of auction rate municipal bonds and variable rate municipal demand notes classified as available-for-sale securities. The Acacia Technologies group's investments in these securities are recorded at cost, which approximates fair market value due to their variable interest rates, which typically reset every 7 to 35 days, and, despite the long-term nature of their stated contractual maturities, the Acacia Technologies group has the ability to quickly liquidate these securities. As a result, there were no cumulative gross unrealized holding gains (losses) or gross realized gains (losses) from current investments. All income generated from these current investments was recorded as interest income. CONCENTRATION OF CREDIT RISKS. Financial instruments that potentially subject the Acacia Technologies group to concentrations of credit risk are cash equivalents and short-term investments. The Acacia Technologies group places its cash equivalents and short-term investments primarily in investment grade, short-term debt instruments. Cash equivalents are invested in deposits with certain financial institutions and may, at times, exceed federally insured limits. The Acacia Technologies group has not experienced any losses on its deposits of cash and cash equivalents. Two of the Acacia Technologies group's licensees accounted for approximately 27% of the Acacia Technologies group's DMT license fee revenues recognized during the year ended December 31, 2004, and one licensee represents approximately 69% of accounts receivable at December 31, 2004. One licensee accounted for approximately 28% of the Acacia Technologies group's license fee revenues recognized during the year ended December 31, 2003, and also represented approximately 82% of accounts receivable at December 31, 2003. The Acacia Technologies group performs regular credit evaluations of its significant licensees and has not experienced any significant credit losses. F-72 PROPERTY AND EQUIPMENT. Property and equipment are recorded at cost. Major additions and improvements that materially extend useful lives of property and equipment are capitalized. Maintenance and repairs are charged against the results of operations as incurred. When these assets are sold or otherwise disposed of, the asset and related depreciation are relieved, and any gain or loss is included in the statement of operations for the period of sale or disposal. Depreciation is computed on a straight-line basis over the following estimated useful lives of the assets: Furniture and fixtures...................... 3 to 5 years Computer hardware and software.............. 3 to 5 years Leasehold improvements...................... Lesser of lease term or useful life of improvement ORGANIZATION COSTS. Costs of start-up activities, including organization costs, are expensed as incurred. PATENTS AND GOODWILL. Goodwill and identifiable intangibles, including patents, are recorded when the consideration paid for acquisitions exceeds the fair value of the net tangible assets acquired. Patents, once issued or purchased, are amortized on the straight-line method over their economic remaining useful lives, ranging from three to twenty years. Goodwill is not amortized. IMPAIRMENT OF LONG-LIVED ASSETS GOODWILL. Long-lived assets and intangible assets are reviewed for potential impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset's carrying value over its fair value is recorded. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. Goodwill is evaluated for impairment in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets" ("SFAS No. 142") and is subject to a periodic review for potential impairment at a reporting unit level. Reviews for potential impairment must occur at least annually and may be performed earlier, if circumstances indicate that an impairment may have occurred. The Acacia Technologies group has elected to perform its annual tests for indications of goodwill impairment as of December 31 of each year. As of December 31, 2004, the Acacia Technologies group has one reporting unit. The fair value of the Acacia Technologies group reporting unit is estimated using a discounted cash flow analysis. SFAS No. 142 requires the Acacia Technologies group to compare the fair value of its reporting unit to its carrying amount on an annual basis to determine if there is potential goodwill impairment. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the fair value of the goodwill within the reporting unit is less than its carrying value. There can be no assurance that future goodwill impairment tests will not result in a charge to earnings. As a result of the August 2004 adverse ruling in Soundview Technologies' V-chip related litigation described at Note 10, as of September 30, 2004, Soundview Technologies was no longer considered a reporting unit of the Acacia Technologies group. FAIR VALUE OF FINANCIAL INSTRUMENTS. The carrying value of cash and cash equivalents, other receivables, accounts payable and accrued expenses approximate fair value due to their short-term maturity. STOCK-BASED COMPENSATION. Refer to Note 2 to the Acacia Research Corporation consolidated financial statements included elsewhere herein. Stock option and related option plan information is omitted from the Acacia Technologies group footnotes because AR-Acacia Technologies stock is part of the capital structure of Acacia Research Corporation.

Refer to the Acacia Research Corporation consolidated financial statements for disclosures regarding Acacia Research Corporation's stock option plans. F-73 INCOME TAXES. Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Acacia Technologies group's financial statements or tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized. SEGMENTS. The Acacia Technologies group follows SFAS No. 131, "Disclosure about Segments of an Enterprise and Related Information," which establishes annual and interim reporting standards for an enterprise's operating segments and related disclosures about its products, services, geographic areas and major customers. Management has determined that the Acacia Technologies group operates in one segment. USE OF ESTIMATES. The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. EARNINGS (LOSS) PER SHARE. Earnings (loss) per share information is omitted from the Acacia Technologies group statements of operations because AR-Acacia Technologies stock is part of the capital structure of Acacia Research Corporation.

As a result of the final ruling in the Acacia Technologies group's V-chip litigation described at Note 10, the Acacia Technologies group recognized $1,500,000 of previously deferred V-chip license fee revenues and $668,000 of previously deferred V-chip related legal costs in the third quarter of 2004. 6. INVESTMENTS In the second quarter of 2003, the Acacia Technologies group recorded an impairment charge of $207,000 for an other-than-temporary decline in the fair value of Acacia Research Corporation's investment in Advanced Data Exchange ("ADX"). Impairment indicators included a continued decline in the working capital of the entity and reference to a recent equity transaction and related valuation indicating an other-than-temporary decline in fair value of the investment. In September 2002, the Acacia Technologies group recorded an impairment charge of $2,748,000 for an other-than-temporary decline in the fair value of ADX. Impairment indicators included recurring losses, a decline in working capital and the completion of a recent equity transaction with a shareholder at an amount below Acacia Research Corporation's carrying value. The fair value of the investment in ADX was determined by reference to available financial and market information. The investment in ADX is accounted for under the cost method. F-75 In 2002, the Acacia Technologies group conducted a portion of its investing activity through a limited partnership, of which a wholly owned subsidiary of Acacia Research Corporation is the general partner. The limited partnership ceased trading activity in May 2002. As a result of the significant control that Acacia Research Corporation exercised over the limited partnership, the assets and liabilities and results of operations have been consolidated by Acacia Research Corporation during 2002. As of December 31, 2002, the limited partnership had distributed all limited partner capital account balances and as a result has no net assets as of December 31, 2002. Prior to cessation of operations, the net assets, liabilities and results of operations of the limited partnership, which included certain health sciences securities, were attributed to the Acacia Technologies group. 7. INTANGIBLES At December 31, 2004 and 2003, the Acacia Technologies group had $121,000 and $1,776,000 of goodwill. At December 31, 2003, goodwill primarily related to the Soundview Technologies reporting unit. In August 2004, as a result of the adverse ruling in Acacia Technologies group's V-chip patent infringement lawsuit described at Note 10, the Acacia Technologies group recorded an impairment charge totaling $1,616,000 in connection with the write-down of 100% of the goodwill related to the V-chip. The Acacia Technologies group's only identifiable intangible assets are patents, which are being amortized over and economic useful life of approximately 9 years. The gross carrying amounts and accumulated amortization related to acquired intangible assets as of December 31, 2004 and 2003 are as follows (in thousands): 2004 2003(1) ---------- ---------- Gross carrying amount - patents......................... $ 4,726 $ 4,753 Accumulated amortization................................ (1,684) (1,187) ---------- ---------- Patents, net............................................ $ 3,042 $ 3,566 ========== ==========
__________ (1) Excludes gross cost and accumulated amortization as of December 31, 2003 totaling $6,045,000 related to the write off of V-chip related intangibles in 2004, in connection with the conclusion of V-chip litigation as discussed at Note 10. Aggregate patent amortization expense was $501,000, $502,000 and $1,591,000 in 2004, 2003 and 2002, respectively. Annual aggregate amortization expense for each of the next five years through December 31, 2009 is estimated to be $500,000 per year. At December 31, 2004 and 2003, all of the Acacia Technologies group's acquired intangible assets other than goodwill were subject to amortization. F-76 8.

At December 31, 2004, the Acacia Technologies group has deferred tax assets totaling approximately $53,324,000, which are fully offset by a valuation allowance due to management's determination that the criteria for recognition have not been met. F-77 At December 31, 2004, the Acacia Technologies group had U.S. federal and state income tax net operating loss carry forwards ("NOLs"), excluding NOLs related to subsidiaries for which Acacia Research Corporation does not file a consolidated return, were approximately $48,704,000 and $38,659,000, expiring between 2005 and 2024. In addition, the Acacia Technologies group had tax credit carryforwards of approximately $62,000. As of December 31, 2004, the aggregate tax NOLs at subsidiaries not consolidated for federal tax purposes are $20,252,000, expiring between 2018 and 2024. However, the use of these NOLs is limited to the separate earnings of the respective subsidiaries. In addition, ownership changes may also restrict the use of NOLs. Had the Acacia Technologies group filed separate tax returns, the benefit for income taxes and division net loss would not have differed from the amounts reported in the Acacia Technologies group's statements of operations for the years ended December 31, 2004, 2003, and 2002. As of December 31, 2004, approximately $9,844,000 of the valuation allowance related to the tax benefits of stock option deductions included in Acacia Research Corporation's NOLs. At such time as the valuation allowance is released, the benefit will be credited to additional paid-in capital. 9. DISCONTINUED OPERATIONS The Acacia Technologies group includes the assets and liabilities of Soundbreak.com, a subsidiary of Acacia Research Corporation, which ceased operations as of February 15, 2001. In September 2004 and 2002, the Acacia Technologies group accrued an additional $104,000 and $200,000 (net of minority interests), respectively, in estimated costs to be incurred in connection with the discontinued operations of Soundbreak.com. The additional accruals relates primarily to certain noncancellable lease obligations and the inability to sublease the related office space at rates commensurate with existing obligations. The assets and liabilities of the discontinued operations at December 31, 2004 and 2003 consist primarily of $889,000 and $1,953,000 of cash and cash equivalents and $275,000 and $388,000 of accounts payable and accrued expenses, respectively. 10. COMMITMENTS AND CONTINGENCIES OPERATING LEASES Acacia Technologies group leases certain office furniture and equipment and office space under various operating lease agreements expiring over the next 3 years. Minimum annual rental commitments for Acacia Technologies group operating leases of continuing operations having initial or remaining noncancellable lease terms in excess of one year are as follows (in thousands): YEAR ---- 2005.................................................. $ 348 2006.................................................. 390 2007.................................................. 49 ---------- Total minimum lease payments.......................... $ 787 ========== Rent expense of continuing operations for the years ended December 31, 2004, 2003 and 2002 approximated $308,000, $467,000 and $445,000, respectively. Acacia Research Corporation is a guarantor under a lease agreement for office space that expires in August 2005. The lease agreement was entered into by Soundbreak.com, which ceased operations in February 2001. The leased premises is subleased through the remaining term of the lease agreement. Refer to Note 9 for additional information regarding discontinued operations. F-78 PATENT ENFORCEMENT AND OTHER LITIGATION Acacia Technologies group is subject to claims, counterclaims and legal actions that arise in the ordinary course of business. Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on the Acacia Technologies group's financial position, results of operations or cash flows. However, the Acacia Technologies group could be subject to claims and legal actions relating to the CombiMatrix group. From time to time, companies comprising the Acacia Technologies group engage in litigation to enforce their patents. Soundview Technologies In September 2002, the United States District Court for the District of Connecticut granted a motion for summary judgment filed by the defendants in Soundview Technologies pending patent infringement and antitrust lawsuit against Sony Corporation of America, the Consumer Electronics Manufacturers Association and the Electronics Industries Alliance d/b/a Consumer Electronics Association in the United States District Court for the Eastern District of Virginia (filed on April 5, 2000), alleging that television sets utilizing certain content blocking technology (commonly known as the "V-chip") and sold in the United States infringe Soundview Technologies' U.S. Patent No. 4,554,584. In granting the motion, the court ruled that the defendants have not infringed on Soundview Technologies' patent. In September 2003, a motion for summary judgment filed by the remaining defendants was granted by the United States District Court for the District of Connecticut on Soundview Technologies' anti-trust claims due to the Court's previous ruling of non-infringement as described above. In August 2004, the U.S. Court of Appeals for the Federal Circuit affirmed the September 2002 U.S. District Court for the District of Connecticut ruling that the remaining television manufacturers named in the Acacia Technologies group's V-chip patent infringement lawsuit do not infringe the Acacia Technologies group's V-chip patent. As a result of the ruling, the Acacia Technologies group recorded an impairment charge of $1,616,000 in connection with the write-off of goodwill related to the V-chip. In addition, as a result of the conclusion of the V-chip patent litigation, the Acacia Technologies group recognized $1,500,000 of V-chip related deferred license fee revenues and $668,000 of V-chip related deferred legal costs in the third quarter of 2004. The remaining Non-Soundview parties have a motion pending before the United States District Court for the District of Connecticut seeking reimbursement of certain attorney's fees. The Acacia Technologies group believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on our financial position, results of operations or cash flows. The final ruling in the V-chip litigation has no impact on the revenues that the Acacia Technologies group has recognized to date from licensees of the Acacia Technologies group V-chip technology. Acacia Media Technologies Corporation CABLE AND SATELLITE TV In 2004, Acacia Media Technologies filed a Complaint in the District Court for the Northern District of California alleging infringement of Acacia Media Technologies' DMT patents against Comcast Corporation, Charter Communications, Inc., The DirectTV Group, Inc., Echostar Communications Corporation, Boulder Ridge Cable TV, Central Valley Cable TV, LLC, Seren Innovations, Inc., Cox Communications, Inc., Hospitality Network, Inc.

F-79 INTERNET WEBSITES In 2003, Acacia Media Technologies initiated DMT patent infringement litigation in the Federal District Court for the Central District of California (the "Court") against defendants who provide adult oriented digital content over the Internet. As of December 31, 2004, New Destiny Internet Group, Inc., Audio Communications Inc., VS Media, Ademia Multimedia, LLC, International Web Innovations, Inc., Offendale Commercial BV, Ltd., Adult Entertainment Broadcast Network, Cybertrend, Inc., Lightspeed Media Corp., Adult Revenue Services, Innovative Ideas International, AskCS.com, Game Link, Inc., Club Jenna, Inc., Cybernet Ventures, Inc., ACMP, LLC, Global AVS, Inc. d/b/a DrewNet, ICS, Inc. / AP Net Marketing, Inc., and National A-1 Advertising, remained in the litigation. HOTEL ON-DEMAND TV INDUSTRY In November 2003, Acacia Media Technologies initiated a patent infringement lawsuit in the Federal District Court for the Central District of California against On Command Corporation, provider of interactive in-room entertainment, information and business services to the lodging industry, regarding Acacia Media Technologies' DMT technology. In June 2004, Acacia Media Technologies entered into a license agreement for its DMT technology with On Command Corporation settling all outstanding litigation between the parties. OTHER In connection with the purchase of the outstanding ownership interests in Acacia Media Technologies Corporation in November 2001, Acacia Media Technologies Corporation also executed related assignment agreements which granted to the former owners of Acacia Media Technologies Corporation's current patent portfolio the right to receive a royalty of 15% of future net revenues, as defined in the agreements, generated by Acacia Media Technologies Corporation's current patent portfolio, which includes its DMT patents. No royalty obligation has been incurred as of December 31, 2004. Any royalties paid pursuant to the agreements will be expensed in the statement of operations. 11. ALLOCATED NET WORTH The Acacia Technologies group's statements of allocated net worth present the equity transactions of Acacia Research Corporation, which are attributed to the Acacia Technologies group as "Net assets attributed to the Acacia Technologies group." This presentation reflects the fact that the Acacia Technologies group does not have legally issued common or preferred stock, nor are warrant issuances or employee stock transactions legal transactions of the Acacia Technologies group.

SUBSEQUENT EVENTS EQUITY FINANCING In February 2005, Acacia Research Corporation raised gross proceeds of $19,600,000 through the sale of 3,500,000 shares of Acacia Research - Acacia Technologies common stock at a price of $5.60 per share in a registered direct offering. Net proceeds raised of approximately $19,575,000, which are net of related issuance costs, were attributed to the Acacia Technologies group. All of the shares of Acacia Research-Acacia Technologies common stock were offered pursuant to an effective registration statement previously filed with the Securities and Exchange Commission. ACQUISITION On January 28, 2005, Acacia Global Acquisition Corporation, a newly formed corporation, acquired the assets of Global Patent Holdings, LLC, a privately held patent holding company based in Northbrook, Illinois, which owned 11 patent licensing companies. The acquisition gives the Acacia Technologies group 100% ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts, and cover technologies used in a wide variety of industries, as set forth below. The acquisition expands and diversifies the Acacia Technologies group's revenue generating opportunities and accelerates the execution of the Acacia Technologies group's business strategy of acquiring, developing and licensing patented technologies. F-81 The acquisition is being accounted for by the purchase method of accounting and, accordingly, the consolidated statement of operations will include the results of the acquired companies beginning on January 28, 2005, the date of acquisition. The aggregate purchase consideration was approximately $24,605,000, including $5.0 million of cash, the issuance of 3,938,832 shares of Acacia Research--Acacia Technologies common stock valued at $19,505,000 and estimated acquisition costs of $100,000. The value of the common shares issued was determined based on the average market price of AR-Acacia Technologies stock, as reported on NASDAQ, over the 5-day period (December 13 - December 17, 2004) before and after the terms of the acquisition were agreed to and announced. The following table summarizes the estimated preliminary total purchase consideration (in thousands): Estimated Purchase Consideration: Cash paid............................................... $ 5,000 Fair value of AR-Acacia Technologies stock issued....... 19,505 Estimated Acquisition costs............................ 100 --------- $ 24,605 ========= Other: Consulting Contract..................................... $ 2,000 =========
Management's determination of the fair value of net assets acquired from Global Patent Holdings and the related purchase price allocation is ongoing and is anticipated to be completed by the end of the first quarter of 2005. The purchase price will be allocated to the assets acquired and liabilities assumed based on their estimated fair market values at the date of acquisition, including, net tangible assets, patents and other identifiable intangibles. Any additional excess purchase price after the initial allocation to identifiable net tangible and identifiable intangible assets will be assigned to goodwill. Amounts attributable to patents will be amortized using the straight-line method over the estimated economic useful life of the underlying patents. The Acacia Technologies group executed a consulting agreement in connection with the acquisition described above, which requires the payment of $2.0 million in consulting fees over a two-year period, and certain reimbursable consulting related expenses, commencing on the date of acquisition. 14.
