Item 1. BUSINESS

OVERVIEW

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.

CombiMatrix Group Split-off Transaction and Related 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 become an independent public company. CombiMatrix Corporation’s registration statement on Form S-1 was declared effective by the Securities and 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 to the Acacia Research Corporation consolidated financial statements, included elsewhere herein, for information regarding 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 the 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 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.

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 of the redemption, to rename AR-Acacia Technologies stock as the only class of common stock, and to provide that all 100,000,000 shares of AR-Acacia Technologies stock currently 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 filed. If adopted, each share of common stock will be entitled to one vote and the relative voting strength of the common stock will be equal notwithstanding the trading price of the common stock.

BUSINESS

Intellectual Property Licensing Business

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, Acacia Global Acquisition Corporation, acquired substantially all of the assets of Global Patent Holdings, LLC, a privately held patent holding company, which owned 11 patent licensing companies (“GPH Acquisition”). In connection with the acquisition we acquired ownership of companies that own or control the rights to 27 patent portfolios, which included 120 U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries. Refer to Note 7 to our consolidated financial statements included in this report for additional information regarding the GPH Acquisition. Subsequent to the GPH Acquisition, we have continued to execute our business strategy in the area of patent portfolio acquisitions, including the acquisition of, or the rights to, a total of 59 additional patent portfolios covering a wide variety of technologies and with applications across several additional industries. These and future patent portfolio acquisitions will continue to expand and diversify our operating subsidiaries' revenue generating opportunities and accelerate the execution of our overall business strategy, as we continue to build our leadership position in patent licensing.

Business Model and Strategy

The business model associated with the licensing and enforcement activities conducted by our operating subsidiaries is summarized in the following diagram:

Our intellectual property acquisition, development, licensing and enforcement business strategy, conducted solely by our operating subsidiaries, includes the 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, including several of the technologies controlled by our operating subsidiaries, some of which are summarized below, become core technologies in the way products and services are manufactured, sold and delivered. Our 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

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 Research 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

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.

Patented Technologies

Currently, on a consolidated basis, our operating subsidiaries own or control the rights to 91 patent portfolios, with patent expiration dates ranging from 2008 to 2027, and covering technologies used in a wide variety of industries, including the following:

· Aligned Wafer Bonding	· Embedded Broadcast Data	· Portable Storage Devices With Links

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.

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.

Item 1A. 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 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.

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.

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 such enforcement actions. While we are not aware that any such changes are likely to occur in 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 difficult to predict the outcome of patent enforcement litigation at the trial level. It is often difficult for juries and trial judges to understand complex, patented technologies, and as a 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 or introduced into the market. See the subheading “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,” 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 length 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 U.S. Patent and Trademark Office (USPTO). The value of our patent portfolios is dependent 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 encounter competition in the area of patent acquisition and enforcement as the number of companies entering this market is increasing. This includes 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. As new technological advances occur, many of our patented technologies may become obsolete before they are completely monetized. If we are unable to replace 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 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.

·	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 more difficult it will be for us to voluntarily license our patents. As a result, we may need to increase the number of our patent enforcement actions to cause infringing companies to license the patent or pay damages for lost royalties. This may increase the risks 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 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 we 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 securities 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 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;

·	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 Global Acquisition Corporation's acquisition of the assets of Global Patent Holdings, LLC in 2005, provided us with ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts. 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. The 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 common 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 from 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;

·	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 court 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 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 markets served by our operating subsidiaries’ licensees frequently undergo transitions in which products rapidly incorporate new features and performance 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 many 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 enforcement of certain patents and patent rights. It is difficult to predict the extent and nature of such liabilities which, in some instances, may be material.

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 court rules, or governing standards relating to the 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 end of 2007. We believe that the fair 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 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. 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 complete loss of the investment in the long-term which may have a material adverse effect on our business, results of operations, liquidity, and financial condition. See Note 2 of our Notes to Consolidated Financial Statements for additional information about our investments in marketable securities.

Recent Market Prices

Acacia Research Corporation’s AR-Acacia Technologies stock and AR-CombiMatrix stock commenced trading on the Nasdaq Stock Market on December 16, 2002, under the symbols “ACTG” and “CBMX,” respectively. Prior to December 16, 2002, Acacia Research Corporation’s only class of common stock began trading under the symbol “ACRI” on the NASDAQ National Market System on July 8, 1996.

As a result of the Split-off Transaction described above, all outstanding shares of AR-CombiMatrix stock were redeemed, and hence, all rights of holders of AR-CombiMatrix stock ceased as of the Redemption Date (August 15, 2007), 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. Subsequent to the consummation of the Split-off Transaction, Acacia Research Corporation’s only class of common stock outstanding is its AR-Acacia Technologies stock.

Prior to the Split-off Transaction, Acacia Research Corporation had two classes of common stock outstanding, its AR-Acacia Technologies stock and its 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. As a result of the Split-off Transaction, the CombiMatrix group is no longer a business group of Acacia Research Corporation.

The markets for securities such as our common stock have historically experienced significant price and volume fluctuations during certain periods. These broad market fluctuations and other factors, such as new product developments and trends in our industry and the investment markets generally, as well as economic conditions and quarterly variations in our results of operations, may adversely affect the market price of our common stock.

The high and low bid prices for our two classes of common stock as reported by NASDAQ for the periods indicated are shown in the table below. Such prices are inter-dealer prices without retail markups, markdowns or commissions and may not necessarily represent actual transactions.

Factors Affecting Comparability:

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 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. Refer to Note 2 and Note 11 to the Acacia Research Corporation consolidated financial statements included elsewhere herein, for additional information and a description of the impact of SFAS No. 123R on our consolidated statements of operations data presented above. Non-cash stock compensation charges included in Marketing, General and Administrative expense were $5,908,000, $3,946,000 and $356,000 in 2007, 2006 and 2005, respectively.

In September 2007, we recorded a non-cash impairment charge of $235,000, related to the write-off of a patent-related intangible asset. In June 2006, we recorded a non-cash charge of $297,000, related to the write-off of a patent-related intangible asset. In June 2003, we recorded an impairment charge of $207,000 for an other-than-temporary decline in the fair value of a cost method investment.

As a result of the conclusion of the V-chip patent litigation, our subsidiary, Soundview Technologies Inc., recognized $1,500,000 of V-chip related deferred license fee revenues, $668,000 of V-chip related deferred legal costs, and a non-cash V-chip related goodwill impairment charge of $1.6 million in the third quarter of 2004.

In January 2005, Acacia Global Acquisition Corporation consummated the GPH Acquisition as described above. The aggregate purchase consideration was approximately $25.1 million, including $5.0 million of cash, the issuance of 3,938,832 shares of Acacia Research-Acacia Technologies common stock, or AR-Acacia Technologies stock, valued at $19.3 million (net of estimated common stock registration costs of $212,000) and acquisition costs, including registration costs, of $796,000. $25.1 million of the purchase price was allocated to patent related intangible assets acquired, which are being amortized on a straight-line basis over a weighted-average estimated economic useful life of six years. As a result of the GPH Acquisition and subsequent patent acquisitions through December 31, 2007, amortization expense totaled $5.6 million, $5.3 million and $4.9 million in 2007, 2006 and 2005, respectively, as compared to approximately $501,000, and $502,000, in 2004 and 2003, respectively.

As a result of the Split-off Transaction, as discussed above, we have disposed of our investment in CombiMatrix Corporation. Refer to Note 10A to the Acacia Research Corporation consolidated financial statements, included elsewhere herein, for information regarding 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”).

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our consolidated financial statements included elsewhere in this Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors including those set forth under item 1A. “Risk Factors” elsewhere herein.

General

CombiMatrix Group Split-off Transaction and Related Discontinued Operations. As discussed below under the caption “Discontinued Operations – Split-off of CombiMatrix Corporation,” the CombiMatrix group, which was previously presented as a separate reportable segment, was split-off from Acacia Research Corporation (the “Split-off Transaction”), effective August 15, 2007 (the “Redemption Date”). As such, the results of operations for the CombiMatrix group in the accompanying consolidated financial statements are presented as part of Acacia Research Corporation’s results from discontinued operations in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” or SFAS No. 144. Accordingly, the CombiMatrix group’s results of operations in prior periods have been reclassified to discontinued operations to conform to the current period presentation.

The intellectual property acquisition, development, licensing and enforcement business conducted by Acacia Research Corporation’s operating subsidiaries, is described more fully in Item 1. “Business,” of this report.

Overview

Our operating activities during 2007, 2006 and 2005, were principally focused on the continued development, licensing and enforcement of the patent 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 increase in license fee revenues in 2007 and 2006 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 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 licensing of our Color Correction for Video Graphics Systems technology, DMT® technology, Audio/Video Enhancement and Synchronization 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 Virtual Computer Workspaces technology licensing programs.

Management measures and assesses the performance and growth of the patent licensing and enforcement business conducted by our operating subsidiaries based on consolidated license fee revenues recognized across all of our technology licensing and enforcement programs on a trailing twelve-month basis. Trailing twelve-month revenues totaled $52.6 million as of December 31, 2007, as compared to $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 $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, business development and engineering personnel, an increase in patent related legal, research and consulting expenses incurred in connection with the continued growth and expansion of our technology licensing and enforcement business and an increase in corporate, general and administrative costs related to ongoing operations. 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 portfolios in each period.

During 2007, certain of our operating subsidiaries continued to execute our business strategy in the area of patent portfolio acquisitions, including, in the fourth 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 a total of 31 new patent portfolios with applications over a wide range of technology areas, as compared to 20 new patent portfolios in 2006 and 8 new patent portfolios in 2005 (excluding portfolios acquired in connection with the 2005 GPH Acquisition).

In January 2005, Acacia Global Acquisition Corporation acquired substantially all of the assets of Global Patent Holdings, LLC, a privately held patent holding company, which owned 11 patent licensing companies (“GPH Acquisition”). In connection with the acquisition we acquired ownership of companies that own or control the rights to 27 patent portfolios, which included 120 U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.

Refer to “Liquidity and Capital Resources” below for information regarding the impact of patent and patent rights acquisitions on Acacia Research Corporation’s consolidated financial statements for the periods 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 financial statements, the following accounting policies require our most difficult, subjective or complex judgments:

·	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, refer to Note 2 to the consolidated financial statements included herein.

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.

We make estimates and judgments when determining whether the collectibility of license fees receivable from licensees is reasonably assured. We assess the collectibility of license fees receivable based on a number of factors, including past transaction history 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.

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 our operating subsidiaries own or control patents. Our 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. Estimates of periodic license fees due could differ from actual events, thus materially impacting our financial position and results of operations.

Our operating subsidiaries are responsible for the licensing and enforcement of their respective patented technologies and pursue third parties that are utilizing their intellectual property without a license or who have under-reported the amount of royalties owed under a license agreement. As a result of these activities, from time to time, our operating subsidiaries may recognize royalty revenues in a current period that relate to infringements by licensees that occurred in prior periods. These royalty recoveries may cause revenues to be higher than expected during a particular reporting period and may not occur in subsequent periods. Differences between amounts initially recognized and amounts subsequently audited or reported as an adjustment to those amounts, are recognized in the period such adjustment is determined as a change in accounting estimate.

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 amends 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 the statement of operations. In March 2005, the SEC published Staff Accounting Bulletin No. 107 (“SAB 107”), which requires stock-based compensation to be classified in the same expense line items as cash compensation (i.e. marketing, general and administrative expenses). The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award (determined using a Black-Scholes option pricing model), and is 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 grant date requires significant estimates and judgments, including estimating the market price volatility of our classes of common stock and employee stock option exercise behavior.

SFAS No. 123R also requires stock-based compensation expense to be recorded only for those awards expected to vest using an estimated pre-vesting forfeiture rate. As such, 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 estimate of pre-vesting forfeitures including types of awards, employee class, and historical pre-vesting forfeiture data. The estimation of stock awards that will ultimately vest requires judgment, and to the extent that actual results differ from our estimates, such amounts will be recorded as cumulative adjustments in the period the estimates are revised. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted.

Refer to Notes 2 and 11 to the Acacia Research Corporation consolidated financial statements included in Part IV, Item 15 of this report for more information.

Valuation of Long-lived and 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:

·	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 intangible assets, estimates of market values, estimates of the amount and timing 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 intangible asset impairment tests may result in a charges to earnings. Refer to Note 6 to the consolidated financial statements, included elsewhere herein, for information on impairment charges recorded during the periods presented.

Impairment of Marketable Securities

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. 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 Other-Than-Temporary-Impairment and Its Application to Certain Investments,” to determine the classification of any impairment as “temporary” or “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 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.

We believe that our investments in certain auction rate securities continue to approximate their par value; however, such risks, including 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 complete loss of the investment in the long-term which may have a material adverse effect on our business, results of operations, liquidity, and financial condition. See Note 2 of our Notes to Consolidated Financial Statements for additional details about our investments in auction rate securities and other marketable securities.

Revenues (In thousands)

	2007		2006		2005

License fees	$	52,597	$	34,825	$	19,574

License Fees. 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. The increase in license fee revenues in 2007 and 2006, as compared to 2005, reflects the impact of the increase in patent portfolios owned or controlled by our operating subsidiaries since 2005, and the related increase in the number of patent licensing and enforcement programs developed, launched and generating revenues since 2005. On a consolidated basis, as of December 31, 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 recognized by our operating subsidiaries fluctuate from period to period primarily based on the 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 our 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.

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

Increase in personnel expenses	$	2,767		$	1,247
Increase (decrease) in GPH Acquisition related consulting expenses		(925	)		96
One-time severance charge for employee separation		360			-
Increase in foreign taxes paid on licensing fees		125			6
Increase in accounting and other professional fees		141			392
Increase in patent development / commercialization and other		1,021			92
Increase in office and facilities and other marketing, general and administrative costs		468			603
Increase in non-cash stock compensation expense		1,962			3,590

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 the same periods.

Results in 2005 included $225,000 of V-chip related inventor royalties expense recognized as a result of the conclusion of all V-chip related litigation activities in October 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 and enforcement programs and the timing of the commencement 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 court, and other litigation support and administrative costs.

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 pocket expenses, third party technical consulting expenses and professional expert expenses incurred in connection with certain of our patent portfolios that are further along in the prosecution 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 acquired patent related costs over a weighted-average remaining economic useful life of approximately four years.

The increase in 2006, as compared to 2005, was due to twelve full months of patent amortization expense resulting from the GPH Acquisition in 2006, as compared to 11 months of amortization 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 during the periods presented.

Write-off of Patent-related Intangible Asset. In September 2007, we recorded a non-cash impairment charge of $235,000, related to the write-off of a patent-related intangible asset. The related licensing program was completed during the third quarter of 2007 resulting in the write-off of the remaining carrying value of the patent-related intangible asset as of September 30, 2007. In June 2006, we recorded a non-cash impairment charge of $297,000, related to the write-off of a patent-related intangible asset. During the second quarter of 2006, pursuant to the terms of the respective license agreement, management elected to terminate its rights to exclusively license and enforce the patent, resulting in the write-off of the remaining carrying value of the patent-related intangible asset as of June 30, 2006.

Discontinued Operations – Split-off of CombiMatrix Corporation

In January 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 common stock in exchange for the distribution of new shares of CombiMatrix Corporation, 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 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 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.

Refer to Note 10A to the Acacia Research Corporation consolidated financial statements included elsewhere herein for information regarding the carrying amount(s) of the major classes of assets, liabilities, revenues and pretax loss included in discontinued operations for the periods presented.

Other Discontinued Operations. Results for 2005 include charges, net of minority interests, of $237,000 related to estimated additional costs to be incurred in connection with the discontinued operations of Soundbreak.com (originally ceased operations in February 2001), related primarily to certain noncancellable lease obligations and a reduction in estimated amounts recoverable from existing sublease arrangements. The related lease obligations, which were guaranteed by Acacia Research Corporation, expired in August 2005.

Inflation

Inflation has not had a significant impact on Acacia Research Corporation or any of our subsidiaries in the current or prior periods.

Liquidity and Capital Resources

Acacia Research Corporation’s consolidated cash and cash equivalents and short-term investments totaled $51.4 million at December 31, 2007, compared to $45.0 million at December 31, 2006. Working capital, related to continuing operations, at December 31, 2007 was $48.1 million, compared to $42.2 million at December 31, 2006.

The net change in cash and cash equivalents and short-term investments related to continuing operations for 2007, 2006 and 2005 was comprised of the following (in thousands):

	2007			2006		2005

Net cash provided by (used in) continuing operations:
Operating activities	$	5,166		$	6,608	$	(2,608	)
Investing activities		(2,145	)		10,513		(13,094	)
Financing activities		5,014			1,475		19,836

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 license fee revenues recognized in 2007, as compared to 2006, as discussed above. The decrease in consolidated net cash inflows from operations in 2007, as compared to 2006, was primarily due to the increases in patent-related legal expenses, personnel expenses, and other corporate, general and administrative expenses, as described above, and the impact of the timing of 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 in 2005, was primarily due to the increase in license fee payments received from licensees, which totaled $38.6 million in 2006, compared to $15.6 million in 2005. The increase in license fee revenues in 2006 was partially offset by increases in inventor royalties expenses, contingent legal fees expenses, patent-related legal expenses, personnel expenses, and other corporate, general and administrative expenses, as described above, and the impact of the timing of payments to inventors, attorneys and other vendors. Consolidated accounts receivable decreased to $269,000 at December 31, 2006, compared to $4.4 million at December 31, 2005, due to the 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 for 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 related 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 of our operating subsidiaries incurred patent acquisition costs of $3.8 million, $1.0 million and $445,000 in 2007, 2006 and 2005, respectively, related to the acquisition of additional patent portfolios, as described earlier.

Financing Activities. Consolidated net cash inflows from financing activities in 2005 included net proceeds of approximately $19.5 million, related to the sale of 3.5 million shares of AR–Acacia Technologies stock in February 2005. Net cash inflows from financing activities in 2007, 2006 and 2005 also included stock option exercise proceeds of $5.0 million, $1.5 million, and $304,000, respectively.

Management believes that Acacia Research Corporation’s consolidated cash and cash equivalent balances, anticipated cash flow from operations and other external sources of available credit, will be sufficient to meet its cash requirements through at least March 2009 and for the foreseeable future. Acacia Research Corporation and its subsidiaries may however encounter unforeseen difficulties that may deplete our capital resources more rapidly than 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 Acacia 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 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. See Note 2 of our Notes to Consolidated Financial Statements for additional details about our investments in auction rate securities and other marketable securities.

Off-Balance Sheet Arrangements

We have not entered into off-balance sheet financing arrangements, other than operating leases. We have no significant commitments for capital expenditures in 2008. We have no committed lines of credit or other committed funding or long-term debt. The following table lists Acacia Research Corporation’s material known future cash commitments as of December 31, 2007, and any material known commitments arising from events subsequent to year end:

	Payments Due by Period (In thousands)
Contractual Obligations		Total		2008		2009		2010		2011		2012		2013 and Thereafter

Operating leases	$	3,850	$	868	$	903	$	939	$	977	$	163	$	-
Total contractual obligations	$	3,850	$	868	$	903	$	939	$	977	$	163	$	-

FIN 48 Liability. Effective January 1, 2007, we adopted the provisions of FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes,” (see Note 2 to the consolidated financial statements included elsewhere herein). As of December 31, 2007, the liability for uncertain tax positions, associated primarily with state income taxes, was $115,000, of which none is expected to be paid within one year. The liability for uncertain tax positions is recorded in other long-term liabilities in the consolidated balance sheet.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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, 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, 2007. Refer to Item 1A. “Risk Factors,” Item 7. “Liquidity and Capital Resources,” and Notes 2 and 3 to the Acacia Research Corporation consolidated financial statements included in this report for additional information.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders of

Acacia Research Corporation

We have audited the accompanying consolidated balance sheet of Acacia Research Corporation (a Delaware 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. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements 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 the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Acacia Research Corporation as of December 31, 2007, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 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) and our report dated March 12, 2008 expressed an unqualified opinion thereon.

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 the 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

of Acacia Research Corporation:

In our opinion, the consolidated balance sheet as of December 31, 2006 and the related consolidated statements of operations and comprehensive loss, shareholders' equity and cash flows for each of the two years in the period ended December 31, 2006, present fairly, in all material respects, the financial position of Acacia Research Corporation and its subsidiaries at December 31, 2006, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2006, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements 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 the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for share-based compensation in 2006.

1. DESCRIPTION OF BUSINESSES

Description of Business. Acacia Research Corporation is comprised of Acacia Research Corporation, and its wholly owned operating subsidiaries. As used herein, “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.

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.

F-8

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Liquidity and Risks

Management believes that Acacia Research Corporation’s consolidated 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 Acacia Research Corporation’s cash requirements, on a consolidated basis, through at least March 2009. To date, we and our subsidiaries have relied primarily upon selling equity securities and payments from our licensees to generate the funds needed to finance the implementation of our plans of operation for our subsidiaries.

There can be no assurance that Acacia Research Corporation will be able to implement its future plans. Failure by management to achieve its plans would have a material adverse effect on Acacia Research Corporation’s ability to achieve its intended business objectives. We may be required to obtain additional financing. There can be no assurance that additional funding will be available on favorable terms, if at all. If we fail to obtain additional funding when needed, we may not be able to execute our business plans and our businesses may suffer.

The timing of the receipt of revenues by Acacia Research Corporation’s operating subsidiaries are subject to certain risks and uncertainties, including:

market acceptance of our operating subsidiaries’ patented technologies and services;

business activities and financial results of our licensees;

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 success also depends on its operating subsidiaries’ ability to protect their intellectual property. Our operating subsidiaries rely on their proprietary rights and their protection. Although reasonable efforts will be taken to protect our 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 our operating subsidiaries are unsuccessful with litigation to protect their intellectual property rights, the future consolidated revenues of Acacia Research Corporation could be adversely affected.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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. The accompanying consolidated financial statements include the accounts of Acacia Research Corporation and its wholly owned subsidiaries. Material intercompany transactions and balances have been eliminated in consolidation. The cost method is used where we maintain ownership interests of less than 20% and do not exercise significant influence over the investee.

Revenue Recognition. We recognize revenue in accordance with Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB No. 104”) and related authoritative pronouncements. 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-9

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Under the terms of our license agreements, our operating subsidiaries grant non-exclusive licenses for the use of patented technologies, which they own or control. In general, pursuant to the terms of the agreements with licensees, upon the grant of the licenses, we have no further obligations with respect to the licenses granted. License fees paid to and recognized as revenue by our subsidiaries are non-refundable.

Revenues generated from license agreements are generally 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’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 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, our 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’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. Amounts of additional royalties due under these license agreements cannot be reasonably estimated by management.

License fee payments received that do not meet the revenue recognition criteria described above are deferred until the revenue recognition criteria are met. We assess the collectibility of license fees receivable based on a number of factors, including past transaction history and 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.

Cash and Cash Equivalents. We consider all highly liquid, short-term investments with original maturities of three months or less when purchased to be cash equivalents.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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”) No. 115, “Accounting for Certain Investments in Debt and Equity Securities” (“SFAS No. 115”). At December 31, 2007 and 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’ equity until realized.

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 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, 2007 and 2006, we held $10,660,000 and $7,288,000, respectively of investment 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 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. As of March 5, 2008, we held $6,250,000 in auction rate 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, despite the long-term nature of their stated contractual maturities. As a result, we had no cumulative gross unrealized holding gains (losses) or gross realized gains (losses) from these investments for the periods presented. All income generated from these current investments was recorded as interest income.

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.

Concentration of Credit Risks. Financial instruments that potentially subject Acacia Research Corporation to concentrations of credit risk are cash equivalents and short-term investments. We place our cash equivalents and short-term investments primarily in investment grade, short-term debt instruments. Cash equivalents are also invested in deposits with certain financial institutions and may, at times, exceed federally insured limits. We have not experienced any significant losses on our deposits of cash and cash equivalents.

Two licensees accounted for 19% and 12% of the license fee revenues recognized during the year ended December 31, 2007. One licensee represented 14% of the license fee revenues recognized during the year ended December 31, 2006 and three licensees accounted for 19%, 15% and 15% of license fee revenues recognized during the year ended December 31, 2005. One licensee represented approximately 89% of accounts receivable at December 31, 2007. Three licensees represented approximately 37%, 24% and 13% of accounts receivable at December 31, 2006.

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

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 consolidated 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	2 to 5 years (Lesser of lease term or useful life of improvement)

Rental payments on operating leases are charged to expense in the consolidated statement of operations on a straight-line basis over the lease term.

Organization Costs. Costs of start-up activities, including organization costs, are expensed as incurred.

Patents. Patents, once issued or purchased, are amortized on the straight-line method over their remaining economic useful lives, ranging from two to seven years.

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’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.

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. Refer to “Short-term Investments” above for information on the fair value of short-term investments.

Stock-Based Compensation. 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 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.

F-12

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 compensation expense 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 revised.

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 accordance 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 granted 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:

	For the Year Ended
	December 31,
	2007	2006

Risk Free Interest Rate	4.64%	4.30%
Term	5.71 years	6 years
Volatility	68%	75%

Option awards granted prior to Acacia Research Corporation’s implementation of SFAS No. 123R were accounted for using the intrinsic value method pursuant to the recognition and measurement principles of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”), and related interpretations. Accordingly, no stock-based employee compensation cost related to option awards was reflected in the accompanying consolidated statements of operations for the year ended December 31, 2005, because all options granted under Acacia Research Corporation’s plans had exercise prices equal to the market value of the underlying common stock on the date of grant. Stock-based compensation expense reflected in the accompanying consolidated statement of operations for the year ended December 31, 2005 related to restricted stock awards originally granted in 2005.

The following table illustrates the pro forma effect on loss from continuing operations and loss per share from continuing operations for the year ended December 31, 2005, if we had applied the fair value recognition provisions of SFAS No. 123 to share-based awards, prior to the adoption of SFAS No. 123R (in thousands, except per share data):

Loss from continuing operations, as reported	$	(6,038	)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 charges 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 adopted the alternative transition method provided in FASB 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 beginning balance of the additional paid-in-capital pool (“APIC pool”) related to the tax effects of employee stock-based compensation which is available to absorb tax deficiencies recognized subsequent to the adoption of 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’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.

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 expected 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.

F-14

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 transaction 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 assess 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 any time since our formation, utilization of the NOL or R&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 stock 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 being 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 our unrecognized tax benefits will not impact our effective tax rate. Any carryforwards that will expire prior to utilization as a result of such limitations will be removed from deferred tax assets with a corresponding reduction of the valuation allowance.

Comprehensive Income (Loss). Comprehensive income (loss) 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. 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’s reportable segments.

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. 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-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-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 (AR-CombiMatrix stock only).

The earnings or losses allocated to each class of common stock are determined by Acacia Research Corporation’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. We believe this method of allocation to be systematic and reasonable.

As a result of the Split-off Transaction, earnings or losses allocated to the CombiMatrix group are presented as discontinued operations in the accompanying consolidated financial statements. Subsequent to the Split-off Transaction, Acacia Research Corporation’s only class of common stock outstanding is its AR-Acacia Technologies stock.

Recent Accounting Pronouncements. In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations (“SFAS No. 141R”). SFAS 141R establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the acquiree and the goodwill acquired. SFAS No. 141R also establishes disclosure requirements to enable the evaluation of the nature and financial effects of business combinations. SFAS No. 141R is effective for Acacia Research Corporation as of January 1, 2009. We are currently evaluating the potential impact of the adoption of SFAS 141R on our consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements—an amendment of Accounting Research Bulletin No. 51 (“SFAS No. 160”). SFAS 160 establishes accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a parent’s ownership interest, and the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS No. 160 also establishes disclosure requirements that clearly identify and distinguish between the interests of the parent and the interests of the noncontrolling owners. SFAS No. 160 is effective for Acacia Research Corporation beginning January 1, 2009. We are currently evaluating the potential impact of the adoption of SFAS 160 on our consolidated financial position, results of operations or cash flows.

In December 2007, the FASB ratified the Emerging Issues Task Force consensus on EITF Issue No. 07-1, Accounting for Collaborative Arrangements (EITF Issue No. 07-1”) that discusses how parties to certain collaborative arrangements should account for various activities. 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 Agent.” Additionally, the consensus provides that income statement characterization of payments between the participants in a collaborative arrangement should be based upon existing authoritative pronouncements; analogy to such pronouncements if not within their scope; or a reasonable, rational, and consistently applied accounting policy election. EITF Issue No. 07-1 is effective for Acacia Research Corporation beginning January 1, 2009 and is to be applied retrospectively to all periods presented for collaborative arrangements existing as of the date of adoption. We do not expect EITF Issue No. 07-1 to have a material impact on our consolidated financial position, results of operations or cash flows.

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.

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

Acacia Research Corporation’s only identifiable intangible assets are patents and patent rights, with estimated remaining economic useful lives up to seven years. The gross carrying amounts and accumulated amortization related to acquired intangible assets as of December 31, 2007 and 2006 are as follows (in thousands):

	2007			2006

Gross carrying amount – patents	$	33,607		$	30,317
Accumulated amortization		(17,300	)		(11,802	)
Patents, net	$	16,307		$	18,515

The weighted-average remaining estimated economic useful life of Acacia Research Corporation’s patents is four years. Aggregate patent amortization expense was $5,583,000, $5,313,000 and $4,922,000 in 2007, 2006 and 2005, respectively. Annual aggregate amortization expense for each of the next five years through December 31, 2012 is estimated to be $4,403,000 in 2008, $3,885,000 in 2009, $3,676,000 in 2010, $2,766,000 in 2011 and $755,000 in 2012.

For the years ended December 31, 2007 and 2006, our operating subsidiaries incurred and capitalized patent acquisition costs totaling $3,760,000 and $1,030,000, respectively, in connection with the acquisition of the rights to several additional patent portfolios. The patents have estimated economic useful lives ranging from five to seven years and are being amortized over a weighted-average economic useful life of seven years for 2007 acquisitions and six years for 2006 acquisitions. At December 31, 2007 and 2006, all of Acacia Research Corporation’s acquired intangible assets were subject to amortization.

In September 2007, we recorded a non-cash impairment charge of $235,000, related to the write-off of a patent-related intangible asset. The related licensing program was completed during the third quarter of 2007 resulting in the write-off of the remaining carrying value of the patent-related intangible asset as of September 30, 2007. In June 2006, we recorded a non-cash impairment charge of $297,000, related to the write-off of a patent-related intangible asset. During the second quarter of 2006, pursuant to the terms of the respective license agreement, management elected to terminate its rights to exclusively license and enforce the patent, resulting in the write-off of the remaining carrying value of the patent-related intangible asset as of June 30, 2006.

7. ACQUISITIONS

On January 28, 2005, Acacia Global Acquisition Corporation, a wholly owned subsidiary of Acacia Research Corporation, acquired substantially all of the assets of Global Patent Holdings, LLC. The acquisition provided us with sole ownership of 11 patent licensing companies that own or control the rights to 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 was accounted for using the purchase method of accounting. Under the purchase method of accounting, the purchase consideration is allocated to the assets acquired, including tangible assets, patents and other identifiable intangibles and liabilities assumed, based on their estimated fair market values at the date of acquisition. The statement of operations for the year ended December 31, 2005 includes the results of the acquired companies beginning on January 28, 2005, the date of acquisition. The aggregate purchase consideration was approximately $25,105,000, including $5.0 million of cash, the issuance of 3,938,832 shares of AR-Acacia Technologies stock valued at $19,293,000 (net of estimated common stock registration costs of $228,000) and other acquisition costs, including registration costs, totaling $812,000. 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 before and after the terms of the acquisition were agreed to and announced.

The following table summarizes the total purchase consideration and the allocation of the consideration paid to the estimated fair value of the assets acquired and liabilities assumed (in thousands):


Purchase Consideration:
Cash paid	$	5,000
Fair value of AR-Acacia Technologies stock issued		19,293
Acquisition and registration costs		812
Total purchase consideration	$	25,105

Purchase Price Allocation:
Fair value of net tangible assets acquired at January 28, 2005	$	(26	)
Intangible assets acquired - patents and patent rights		25,131
Total	$	25,105

Management was primarily responsible for determining the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed at the date of acquisition. Management considered a number of factors, including reference to an independent valuation. The patents and patent rights acquired were valued using a discounted cash flow model on a patent portfolio by portfolio basis, which estimated the future net cash flows expected to result from the licensing of each 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 associated with achieving the estimated net cash flows was used to estimate the present value of future estimated net cash flows. Management’s valuation resulted in an estimated fair value of patent related assets acquired of approximately $27,000,000, resulting in approximately $1,900,000 of excess fair value over the cost of net assets acquired, which has been allocated as a pro rata reduction to the amounts that otherwise would have been assigned to the assets acquired, in accordance with the purchase method of accounting.

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 consulting agreement. The consulting agreement expired in January 2007.

The acquisition was treated for tax purposes as a taxable asset acquisition and, as 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 connection with the application of the purchase method of accounting.

8. STOCKHOLDERS’ EQUITY

Capital Stock

As of December 31, 2007, the authorized capital stock of Acacia Research Corporation consists of 210,000,000 shares, of which 100,000,000 shares is a class of common stock designated as “AR–Acacia Technologies stock,” having a par value of $0.001 per share, 100,000,000 shares is a class of common stock designated as “AR–CombiMatrix stock,” having a par value of $0.001 per share, and 10,000,000 is a class of preferred stock having a par value of $0.001 per share (the “Preferred Stock”) and issuable in one or more series as determined by the board of directors pursuant to Acacia Research Corporation’s restated certificate of incorporation.

Holders of our classes of common stock vote together as a single class (except in certain limited circumstances). Subsequent to the consummation of the Split-off Transaction on August 15, 2007, as described above at Note 1, Acacia Research Corporation’s only class of common stock outstanding is its AR-Acacia Technologies stock. Holders of each class of common stock are entitled to receive ratably such dividends, if any, as may be declared by the board of directors out of funds legally available therefore.

Under our restated certificate of incorporation, in the event of our dissolution, liquidation or winding up, after payment or provision for payment of the debts and other liabilities and full preferential amounts to which holders of any preferred stock are entitled, the holders of our common stock will be entitled to receive our assets remaining for distribution to holders of common stock on a per share basis in proportion to the liquidation units per share of such class. Holders of each class of common stock have no preemptive, subscription, redemption or conversion rights.

Acacia Research Corporation’s board of directors, subject to state laws and limits in our restated certificate of incorporation, including those discussed above, are able to declare dividends on our common stock in its discretion. To date, Acacia Research Corporation has never paid or declared cash dividends on shares of our stock, nor do we anticipate paying cash dividends on either of the two classes of stock in the foreseeable future.

In connection with the consummation of the Split-off Transaction 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 exchange for the distribution of new shares of CombiMatrix Corporation common stock. Subsequent to the consummation of the Split-off Transaction, Acacia Research Corporation’s only class of common stock outstanding is its AR-Acacia Technologies common stock. Pursuant to Acacia Research Corporation’s amended and restated certificate of incorporation, neither class of common stock is redeemable as of and subsequent to the Redemption Date. As such, we no longer label the common stock in the accompanying consolidated balance sheet as of December 31, 2007 and statement of stockholders’ equity for the year ended December 31, 2007 as “redeemable.”

In February 2008, our Board of Directors approved an amendment and restatement of our certificate of incorporation to remove reference to AR-CombiMatrix stock which was cancelled as a result of the redemption described above, to rename AR-Acacia Technologies stock as the only class of common stock, and to provide that all 100,000,000 shares of AR-Acacia Technologies stock currently 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. If adopted, each share of common stock will be entitled to one vote and the relative voting strength of the common stock will be equal notwithstanding the trading price of the common stock.

Other

In February 2005, Acacia Research Corporation raised gross proceeds of $19,600,000 through the sale of 3,500,000 shares of AR-Acacia Technologies stock at a price of $5.60 per share in a registered direct offering. Proceeds raised, net of related issuance costs, totaled approximately $19,532,000.

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

At December 31, 2007, Acacia Research Corporation had U.S. federal and state income tax net operating loss carry forwards (“NOLs”), totaling approximately $58,258,000 and $41,961,000, expiring between 2010 and 2027, and 2008 and 2017, respectively. In addition, Acacia Research Corporation had tax credit carryforwards of approximately $40,000.

As of December 31, 2007, approximately $11,762,000 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. 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 January 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 the 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 hence, all rights of 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.

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 incurred in connection with the Split-off Transaction, originally included in Acacia Research Corporation corporate accounts, totaling $136,000 for the year ended December 31, 2007.

10A. DISCONTINUED OPERATIONS – SPLIT-OFF OF COMBIMATRIX CORPORATION

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 consummation 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 carrying amounts of the major classes of assets and liabilities and revenues and pretax loss included in discontinued operations for the following periods were as follows (in thousands):

11. STOCK-BASED INCENTIVE PLANS

The 2002 Acacia Technologies Stock Incentive Plan (“2002 Plan”) and the 2007 Acacia Technologies Stock Incentive Plan (“2007 Plan”) (collectively, the “Plans”) were approved by the stockholders of Acacia Research Corporation in December 2002 and May 2007, respectively. Both Plans allow grants of stock options, stock awards and performance shares with respect to AR-Acacia Technologies stock to eligible individuals, which generally includes directors, officers, employees and consultants. Except as noted below, the terms and provisions of the Plans are identical in all material respects.

F-23

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Acacia Research Corporation’s compensation committee administers the discretionary option grant and stock issuance programs. The compensation committee determines which eligible individuals are to receive option grants or stock issuances under those programs, the time or times when the grants or issuances are to be made, the number of shares subject to each grant or issuance, the status of any granted option as either an incentive stock option or a non-statutory stock option under the federal tax laws, the vesting schedule to be in effect for the option grant or stock issuance and the maximum term for which any granted option is to remain outstanding. The exercise price of options is generally equal to the fair market value of the AR-Acacia Technologies stock on the date of grant. Options generally begin to be exercisable six months to one year after grant and generally expire ten years after grant. Stock options generally vest over two to three years and restricted shares generally vest in full after two to three years (generally represents the requisite service period in accordance with SFAS No. 123R).

Programs

The Plans provide for the following separate programs:

Discretionary Option Grant Program. Under the discretionary option grant program, our compensation committee may grant (1) non-statutory options to purchase shares of AR-Acacia Technologies stock to eligible individuals in the employ or service of Acacia Research Corporation or our subsidiaries (including employees, non-employee board members and consultants) at an exercise price not less than 85% of the fair market value of those shares on the grant date and (2) incentive stock options to purchase shares of AR-Acacia Technologies stock to eligible employees at an exercise price not less than 100% of the fair market value of those shares on the grant date (not less than 110% of fair market value if such employee actually or constructively owns more than 10% of our voting stock or the voting stock of any of our subsidiaries).

Stock Issuance Program. Under the stock issuance program, eligible individuals may be issued shares of AR-Acacia Technologies stock directly, upon the attainment of performance milestones or the completion of a specified period of service or as a bonus for past services. Under this program, the purchase price for the shares shall not be less than 100% of the fair market value of the shares on the date of issuance, and payment may be in the form of cash or past services rendered.

Automatic Option Grant Program (2002 Plan only). Under the automatic option grant program, option grants will automatically be made at periodic intervals to eligible non-employee members of our board of directors to purchase shares of AR-Acacia Technologies stock at an exercise price equal to 100% of the fair market value of those shares on the grant date. Each individual who first becomes a non-employee board member at any time after the date of the adoption of the incentive plans by our board of directors will automatically receive an option to purchase 20,000 shares of AR-Acacia Technologies stock on the date the individual joins the board of directors. In addition, on the first business day in each calendar year following the adoption of the incentive plans by our board of directors, each non-employee board member then in office, including each of our current non-employee board members who is then in office, will automatically be granted an option to purchase 15,000 shares of AR-Acacia Technologies stock, provided that the individual has served on the board of directors for at least six months.

Commencing in fiscal 2008, in lieu of the option grants described above, each non-employee director will receive restricted stock units for the number of shares determined by dividing the annual retainer by the closing price of the common stock on the grant date, provided that such individual has served as a non-employee director for at least 6 months. In addition, as of May 2007, each new non-employee director will receive restricted stock units for the number of shares determined by dividing the annual Board of Directors retainer by the closing price of the common stock on the commencement date.

The number of shares of common stock available for issuance under the 2002 Plan automatically increases on the first trading day of January each calendar year during the term of the Plan by an amount equal to three percent (3%) of the total number of shares of common stock outstanding on the last trading day in December of the immediately preceding calendar year, but in no event shall any such annual increase exceed 500,000 shares. The aggregate number of shares of common stock available for issuance under the 2002 Plan shall not exceed 20,000,000 shares. At December 31, 2007, there were 18,000 shares available for grant under the 2002 Plan.

F-24

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The initial share reserve under the 2007 Plan was 560,000 shares. The number of shares of common stock available for issuance under the 2007 Plan automatically increases on January 1, 2008 and 2009, by an amount equal to two percent (2%) of the total number of shares of our common stock outstanding on the last trading day of December in the prior calendar year, except that the automatic increase in the share reserve will be three percent (3%) of our outstanding common stock on such January 1, if our common stock has appreciated by at least thirty percent (30%) in the prior calendar year. After January 1, 2009, no new additional shares will be added to the 2007 Plan without stockholder approval (except for shares subject to outstanding awards that are forfeited or otherwise returned to the 2007 Plan). At December 31, 2007, there were 171,000 shares available for grant under the 2007 Plan.

The Plans do not segregate the number of securities remaining available for future issuance among stock options and other awards. The shares authorized for future issuance represents the total number of shares available through any combination of stock options or other awards. Upon the exercise of stock options or the granting of restricted stock, it is Acacia Research Corporation’s policy to issue new shares of the respective class of common stock.

Our board of directors may amend or modify the Plans at any time, subject to any required stockholder approval. The Plans will terminate no later than the tenth anniversary of the approval of the incentive plans by our stockholders.

The following table summarizes stock option activity for the Plans for the year ended December 31, 2007:

12. COMMITMENTS AND CONTINGENCIES

Operating Leases

Acacia Research Corporation leases certain office space under various operating lease agreements expiring in 2012. Minimum annual rental commitments for operating leases of continuing operations having initial or remaining noncancellable lease terms in excess of one year are as follows (in thousands):

Year
2008	$	868
2009		903
2010		939
2011		977
2012		163
Total minimum lease payments	$	3,850

Rent expense related to continuing operations for the years ended December 31, 2007, 2006 and 2005 approximated $749,000, $565,000 and $453,000, respectively. Rental payments are expensed in the statement of operations in the period to which they relate. Scheduled rent increases are amortized on a straight-line basis over the lease term.

Inventor Royalties and Contingent Legal Expenses

In connection with the acquisition of certain patents and patent rights, certain operating subsidiaries of Acacia Research Corporation executed related agreements which grant to the former owners of the respective patents or patent rights, the right to receive inventor royalties based on future net license fee revenues (as defined in the respective agreements) generated as a result of licensing the respective patents or patent portfolios. Inventor royalties paid pursuant to the agreements are expensed in the consolidated statement of operations in the period that the related license fee revenues are recognized. In certain instances, pursuant to the terms of the underlying inventor agreements, costs paid by us to acquire patents are recoverable from future net revenues. Patent acquisition costs that are recoverable from future net revenues are amortized over the estimated economic useful life of the related patents, or as the prepaid royalties are earned by the inventor, as appropriate, and the related expense is included in amortization expense in the consolidated statement of operations. Any unamortized patent acquisition costs recovered from net revenues are expensed in the period recovered, and included in inventor royalties and contingent legal fees – patents in the consolidated statement of operations.

In connection with the licensing and enforcement activities of our operating subsidiaries, they may retain the services of law firms that specialize in intellectual property licensing and enforcement and patent law. These law firms may be retained on a contingent fee basis in which the law firms are paid on a scaled percentage of any negotiated license fees, settlements or judgments awarded based on how and when the license fees, settlements or judgments are obtained. In instances where there are no recoveries from potential infringers (ie. license fees), no contingent legal fees are paid; however, our operating subsidiaries may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement. Legal fees advanced by contingent law firms that are required to be paid in the event that no license recoveries are obtained are expensed as incurred and included in liabilities in the consolidated balance sheet.

ACACIA RESEARCH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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. Operating subsidiaries of Acacia Research Corporation are often required to engage in litigation to enforce their patents and patent rights.

Guarantees and Indemnifications

Certain of our operating subsidiaries have made guarantees and indemnities under which they may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business. In connection with certain facility leases Acacia Research Corporation and certain of its operating subsidiaries have indemnified lessors for certain claims arising from the facilities or the leases. Acacia Research Corporation indemnifies its directors and officers to the maximum extent permitted under the laws of the State of Delaware. However, Acacia Research Corporation has a directors and officers insurance policy that may reduce its exposure in certain circumstances and may enable it to recover a portion of future amounts that may be payable, if any. The duration of the guarantees and indemnities varies and, in many cases is indefinite but subject to statute of limitations. The majority of guarantees and indemnities do not provide any limitations of the maximum potential future payments that we could be obligated to make. To date, we have made no payments related to these guarantees and indemnities. We estimate the fair value of our indemnification obligations to be insignificant based on this history and have therefore, not recorded any liability for these guarantees and indemnities in the accompanying consolidated balance sheets.

13. RETIREMENT SAVINGS PLAN AND EXECUTIVE SEVERANCE POLICY

Retirement Savings Plan. Acacia Research Corporation 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. Acacia Research Corporation may contribute to the Plan at the discretion of the board of directors. There were no contributions made by Acacia Research Corporation during the years ended December 31, 2007, 2006 and 2005.

Executive Severance Policy. Under Acacia Research Corporation’s Executive Severance Policy, full-time employees with the title of Senior Vice President and higher (“Officer”) are entitled to receive certain benefits upon termination of employment. If employment of an Officer is terminated for other than cause or other than on account of death or disability, Acacia Research Corporation will (i) promptly pay to the Officer a lump sum amount equal to the aggregate of (a) accrued obligations ( i.e., the Officer’s annual base salary through the date of termination to the extent not theretofore paid and any compensation previously deferred by the Officer (together with any accrued interest or earnings thereon) and any accrued vacation pay, and reimbursable expenses, in each case to the extent not theretofore paid) and (b) three (3) months of the Officer’s base salary for each full year that the Officer was employed by the Company (the "Severance Period"), up to a maximum of twelve (12) months of the Officer's base salary and (ii) provide to the Officer, Acacia Research Corporation paid COBRA coverage for the medical and dental benefits selected by the Officer in the year in which the termination occurs, for the duration of the Severance Period.

In 2005, Acacia Research Corporation accrued an additional $237,000 (net of minority interests), respectively, in estimated costs to be incurred in connection with the discontinued operations of Soundbreak.com (originally ceased operations in February 2001). The additional accruals relate primarily to certain noncancellable lease obligations, the inability to sublease the related office space at rates commensurate with our existing obligations and certain lease termination costs. The related lease obligations, which were guaranteed by Acacia Research Corporation, expired in August 2005. The assets and liabilities related to the discontinued operations of Soundbreak.com at December 31, 2007 and 2006 were not material.

This information has been derived from our unaudited condensed consolidated financial statements that have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the information when read in conjunction with the audited consolidated financial statements and related notes thereto. Our quarterly results have been in the past and may in the future be subject to significant fluctuations. As a result, we believe that results of operations for interim periods should not be relied upon as any indication of the results to be expected in any future periods.

As a result of the Split-off Transaction (refer to Notes 10 and 10A), we have disposed of our investment in CombiMatrix Corporation, and therefore, in accordance with guidance set forth in SFAS No. 144, the statement of operations data for the four quarters in the period ended December 31, 2007, presented below, reflect the results of operations for CombiMatrix Corporation as discontinued operations. The unaudited consolidated statement of operations data for the four quarters in the period ended December 31, 2006, presented below, have been reclassified to conform to this presentation.
