The Company And Basis Of Presentation	'
	THE COMPANY AND BASIS OF PRESENTATION
	Tessera Technologies, Inc. and its subsidiaries (the “Company”) generate revenue from licensing to manufacturers and other implementers that use the Company's technology in areas such as mobile computing and communications, memory and data storage, and 3-D Integrated Circuit (“3DIC”) technologies. The Company's technology is both developed internally and acquired and includes chip-scale packaging solutions, interconnect solutions and solutions for mobile imaging which include its FaceToolsTM, FacePowerTM, FotoSavvyTM, face beautification, red-eye removal, High Dynamic Range, panorama, and image stabilization intellectual property.
	The accompanying interim unaudited condensed consolidated financial statements as of September 30, 2014 and 2013, and for the three and nine months then ended, have been prepared by the Company in accordance with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”) for interim financial information. The amounts as of December 31, 2013 have been derived from the Company’s annual audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary (consisting of normal recurring adjustments) to state fairly the financial position of the Company and its results of operations and cash flows as of and for the periods presented. These financial statements should be read in conjunction with the annual audited financial statements and notes thereto as of and for the year ended December 31, 2013, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, filed on March 3, 2014 (the “Form 10-K”).
	The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the full year ended December 31, 2014 or any future period and the Company makes no representations related thereto.
	Reclassification
	Certain reclassifications have been made to prior period balances in order to conform to the current period’s presentation. In addition, certain operations are being classified in discontinued operations, and these items have been correspondingly reclassified for all prior periods presented. See Note 5 - “Discontinued Operations.”

Summary Of Significant Accounting Policies	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	There have been no significant changes in the Company’s significant accounting policies during the nine months ended September 30, 2014, as compared to the significant accounting policies described in the Form 10-K.
	Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry-forward, a Similar Tax Loss, or a Tax Credit Carry-forward Exists.” This ASU provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carry forward or a tax credit carry forward exists. Under the ASU, the Company’s unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward or a tax credit carry forward. This ASU applies to all entities that have unrecognized tax benefits when a net operating loss carry-forward, a similar tax loss, or a tax credit carry-forward exists at the reporting date. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Company's financial statements.
	Recent Accounting Pronouncements
	In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification Topic No. 718, “Compensation - Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of ASU 2014-12 is not expected to have a material effect on the Company’s unaudited condensed consolidated financial statements or disclosures.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (“ASU 2014-09”), which provides guidance for revenue recognition. ASU 2014-09 affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets and supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition,” and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” ASU 2014-09’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is effective for the Company beginning January 1, 2017 and, at that time, the Company may adopt the new standard under the full retrospective approach or the modified retrospective approach. Early adoption is not permitted. The Company is currently evaluating the method and impact the adoption of ASU 2014-09 will have on the Company’s unaudited condensed consolidated financial statements and disclosures.
	In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 changes the criteria for reporting a discontinued operation. Under the new pronouncement, a disposal of a part of an organization that has a major effect on its operations and financial results is a discontinued operation. The Company is required to adopt ASU 2014-08 prospectively for all disposals or components of its business classified as held for sale during fiscal periods beginning after December 15, 2014. The Company is currently evaluating what impact, if any, the adoption of this ASU will have on the presentation of the Company's financial statements.

	Short-term investments									285,865
	Total marketable securities									$	303,838
	At September 30, 2014 and December 31, 2013, the Company had $398.7 million and $359.6 million, respectively, in cash, cash equivalents and short-term investments. The majority of these amounts were held in marketable securities, as shown above. The remaining balance of $21.6 million and $55.8 million at September 30, 2014 and December 31, 2013, respectively, was cash held in operating accounts not included in the tables above.
	The gross realized gains and losses on sales of marketable securities were not significant during the three and nine months ended September 30, 2014 and 2013.
	Unrealized loss (net of unrealized gains) of $(0.1) million, net of tax, as of September 30, 2014, were related to temporary fluctuations in value of the remaining available-for-sale securities and were due primarily to changes in interest rates and market and credit conditions of the underlying securities. Certain investments with a temporary decline in value are not considered to be other-than-temporarily impaired as of September 30, 2014 because the Company has the ability to hold these investments to allow for recovery, and does not anticipate having to sell these securities with unrealized losses and continues to receive interest at the maximum contractual rate. For the three and nine months ended September 30, 2014 and 2013, respectively, the Company did not record any impairment charges related to its marketable securities.
	The following table summarizes the fair value and gross unrealized losses related to individual available-for-sale securities at September 30, 2014 and December 31, 2013, which have been in a continuous unrealized loss position, aggregated by investment category and length of time (in thousands):

	DISCONTINUED OPERATIONS
	The following are included in the Company's discontinued operations:
	•	In the second quarter of 2012, the Company completed an acquisition of certain assets of Vista Point Technologies, from Flextronics International Ltd. (the “Zhuhai Transaction”). At the time of the closing, the Company intended to use the acquired assets and related manufacturing business to accelerate its strategy of building the DigitalOptics business into a manufacturer and supplier of camera modules in the mobile phone market. However, in the first quarter of 2013, the Company determined the DigitalOptics business was to be restructured and announced its plans to close its leased manufacturing facility in Zhuhai, China. As a result of this restructuring, certain assets acquired in the transaction were considered impaired or written off entirely.
	•	In the third quarter of 2013, the Company continued to restructure its DigitalOptics business through the sale of its Micro-Optics business based in Charlotte, North Carolina. Originally purchased in 2006, this business focused on diffractive optical elements, refractive optical elements, and integrated micro-optic sub-assemblies. The Company determined these offerings were no longer part of its long-term strategy for the DigitalOptics business. As a result, in August 2013, the Company sold all of the related assets of the Micro-Optics business. The Company retained ownership of the related land and building and certain fabrication assets for this facility. These assets were classified as assets held for sale until they were sold in August 2014.
	•	In the first quarter of 2014, the Company announced the cessation of all mems|cam manufacturing operations. This was the last manufacturing operation in the DigitalOptics business. This action will include a reduction of over 300 employees and a closure of facilities in Arcadia, California, Rochester, New York and in Taiwan and Japan.
	For more information regarding these actions, see Note 7 – "Goodwill and Identified Intangible Assets" and Note 14 – "Restructuring, Impairment of Long-Lived Assets and Other Charges."
	The businesses discussed above are considered discontinued operations, and accordingly, the Company has reported the results of operations and financial position of these businesses in discontinued operations within the Condensed Consolidated Statements of Operations and Condensed Consolidated Balance Sheets for all periods presented.

	(1) As noted above, in January 2014, the Company announced the cessation of all mems|cam manufacturing operations. As part of these actions, the Company incurred severance and accelerated lease obligations and other charges. See Note 14 for additional information.
	(2) As part of the restructuring of its DigitalOptics business, the Company incurred $5.2 million in workforce and corporate overhead reductions and $13.7 million impairment of long-lived assets, which included an $8.7 million charge due to the abandonment of patents and technology which caused a revision of the useful life estimate of these patent and technology assets thus fully impairing them.
	(3) See Note 7 – "Goodwill and Identified Intangible Assets."
	The current assets and current liabilities of discontinued operations were as follows (in thousands):

	Long-term liabilities of discontinued operations	$	197			$	197
	(1) The decrease in the September 30, 2014 balance from the December 31, 2013 balance results from the sale of land and building assets of our DigitalOptics operations in Charlotte in August 2014, partially offset by the inclusion in discontinued operations of assets related to our former mems|cam manufacturing operations since January 2014, whereas they were included in continuing operations as of December 31, 2013. The mems/cam assets are classified as held for sale.
	(2) The increase in the September 30, 2014 balances from the December 31, 2013 balances is related to the cessation of all mems|cam manufacturing operations with the liabilities of those operations being included in discontinued operations since 2014, whereas they were included in continuing operations as of December 31, 2013. At September 30, 2014, this amount is primarily related to lease obligations, purchase commitments and employee severance.

Fair Value	'
	FAIR VALUE
	The Company follows the authoritative guidance for fair value measurement for financial assets and financial liabilities. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability, or an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The established fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:
	Level 1		Quoted prices in active markets for identical assets.
	Level 2		Observable inputs other than Level 1 prices, such as quoted prices for similar assets; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets.
	Level 3		Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
	The following is a list of the Company’s assets required to be measured at fair value on a recurring basis and where they were classified within the hierarchy as of September 30, 2014 (in thousands):

	GOODWILL AND IDENTIFIED INTANGIBLE ASSETS
	In March 2013, the Company revised its business strategy for the DigitalOptics business to concentrate its manufacturing efforts on the lens barrel, rather than the whole camera module. This revised strategy made the Zhuhai Facility unnecessary. The Company announced the closure of the Zhuhai Facility in March 2013. This decision triggered an impairment review of the related goodwill and purchased intangible assets. As a result of the Company's impairment assessment, completed in the first quarter of 2013, the Company recorded an impairment charge to goodwill of $6.7 million.
	Identified intangible assets consisted of the following (in thousands):

	NET INCOME (LOSS) PER SHARE
	The Company has a share-based compensation plan under which employees may be granted share-based awards including shares of restricted stock and restricted stock units ("RSUs"). Non-forfeitable dividends are paid on unvested shares of restricted stock. No dividends are accrued or paid on unvested RSUs. As such, shares of restricted stock are considered participating securities under the two-class method of calculating earnings per share. The two-class method of calculating earnings per share did not have a material impact on the Company’s earnings per share calculation for the three and nine months ended September 30, 2014 and 2013.
	The following table sets forth the computation of basic and diluted shares (in thousands):
		Three Months Ended				Nine Months Ended

	Total common shares-diluted	53,286		54,076		53,519		53,199
	Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period, excluding any unvested restricted stock awards that are subject to repurchase. Diluted net income (loss) per share is computed using the treasury stock method to calculate the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential dilutive common shares include unvested restricted stock awards and units and incremental common shares issuable upon the exercise of stock options, less shares from assumed proceeds. The assumed proceeds calculation includes actual proceeds to be received from the employee upon exercise, the average unrecognized stock compensation cost during the period and any tax benefits that will be credited upon exercise to additional paid-in capital.
	For the three and nine months ended September 30, 2014, in the calculation of net income per share, 1.0 million and 2.0 million shares, respectively, subject to stock options and restricted stock awards and units were excluded from the computation of diluted net loss per share as they were anti-dilutive.
	For the three and nine months ended September 30, 2013, in the calculation of net loss per share, all 2.2 million and 2.9 million shares, respectively, subject to stock options and restricted stock awards and units were excluded from the computation of diluted net loss per share as they were anti-dilutive.

	Stock Repurchase Programs
	In August 2007, the Company’s Board of Directors (“the Board”) authorized a plan to repurchase up to a maximum total of $100.0 million of the Company’s outstanding shares of common stock dependent on market conditions, share price and other factors. In November 2013, the Board increased the amount authorized to be used for repurchases to $150.0 million. In October 2014, the Board increased the amount authorized to be used for repurchases to $250.0 million. As of September 30, 2014, the Company had repurchased a total of approximately 4,435,000 shares of common stock, since inception of the plan, at an average price of $20.11 per share for a total cost of $89.2 million. As of December 31, 2013, the Company had repurchased a total of approximately 2,145,000 shares of common stock, since inception of the plan, at an average price of $18.32 per share for a total cost of $39.3 million. The shares repurchased are recorded as treasury stock and are accounted for under the cost method. No expiration date has been specified for this plan. As of September 30, 2014, the total amount available for repurchase was $60.8 million and after taking into account the additional $100 million authorized by the Board in October 2014, approximately $160 million as of the date of this filing. The Company plans to continue to execute authorized repurchases from time to time under the plan.
	Stock Option Plans
	The 2003 Plan
	In February 2003, the Board adopted and the Company’s stockholders approved the 2003 Equity Incentive Plan (“2003 Plan”). Under the 2003 Plan, incentive stock options may be granted to the Company’s employees at an exercise price of no less than 100% of the fair value on the date of grant, and non-statutory stock options may be granted to the Company’s employees, non-employee directors and consultants at an exercise price of no less than 85% of the fair value. In both cases, when the optionees own stock representing more than 10% of the voting power of all classes of stock of the Company, the exercise price shall be no less than 110% of the fair value on the date of grant. Options under the 2003 Plan generally have a term of ten years from the date of grant. Options, restricted stock awards, and restricted stock units granted under the 2003 Plan generally vest over a four-year period. Restricted stock, performance awards, dividend equivalents, deferred stock, stock payments and stock appreciation rights may also be granted under the 2003 Plan either alone, in addition to, or in tandem with any options granted thereunder. Restricted stock awards and units are full-value awards that reduce the number of shares reserved for grant under this plan by one and one-half shares for each share granted. The vesting criteria for restricted stock awards and units is generally the passage of time or meeting certain performance-based objectives, and continued employment through the vesting period generally over four years. As of September 30, 2014, there were approximately 4.8 million shares reserved for future grant under the 2003 Plan.

	Performance awards and units may be granted to employees or consultants based upon, among other things, the contributions, responsibilities and other compensation of the particular employee or consultant. The value and the vesting of such performance awards and units are generally linked to one or more performance goals or other specific performance goals determined by the Company, in each case on a specified date or dates or over any period or periods determined by the Company, and range from zero to 100 percent of the grant.
	Employee Stock Purchase Plans
	In August 2003, the Board adopted the 2003 Employee Stock Purchase Plan (the "ESPP"), which was approved by the Company’s stockholders in September 2003 and became effective February 1, 2004. Subsequently, the Board adopted the International Employee Stock Purchase Plan (the “International ESPP”) in June 2008.
	As of September 30, 2014, there were approximately 574,000 shares reserved for grant under the ESPP and the International ESPP, collectively.

	The Company uses the Black-Scholes option pricing model to determine the estimated fair value of options. The fair value of each option grant is determined on the date of grant and the expense is recorded on a straight-line basis. The assumptions used in the model include expected life, volatility, risk-free interest rate, and dividend yield. The Company’s determinations of these assumptions are outlined below.
	Expected life – The expected life assumption is based on analysis of the Company’s historical employee exercise patterns. The expected life of options granted under the ESPP represents the offering period of two years.
	Volatility – Volatility is calculated using the historical volatility of the Company’s common stock for a term consistent with the expected life. Historical volatility of the Company’s common stock is also utilized for the ESPP.
	Risk-free interest rate – The risk-free interest rate assumption is based on the U.S. Treasury rate for issues with remaining terms similar to the expected life of the options.
	Dividend yield – Expected dividend yield is calculated based on the cash dividend declared by the Board for the past four quarters and dividing that result by the average closing price of the Company’s common stock for the quarter. Cash dividends are not paid on options, restricted stock units or unvested restricted stock awards.
	In addition, the Company estimates forfeiture rates. Forfeitures are estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. Historical data is used to estimate pre-vesting option forfeitures and the Company records stock-based compensation expense only for those awards that are expected to vest.
	The following assumptions were used to value the options granted:
		Three Months Ended						Nine Months Ended
		30-Sep-14			30-Sep-13			30-Sep-14		30-Sep-13
	Expected life (in years)	4.9			5			4.9		5
	Risk-free interest rate	1.8	%		1.4	%		1.6-1.8%		0.8-1.4%

	Expected volatility	37.3	%		56.7	%		37.3 - 41.4%		56.7 - 59.5%
	ESPP grants occur in February and August. The following assumptions were used to value the ESPP shares for these grants:
			Feb-14			Feb-13			Aug-14		Aug-13
	Expected life (years)		2			2			2		2
	Risk-free interest rate		0.3	%		0.3	%		0.5	%	0.4	%

	INCOME TAXES
	The benefit from income taxes for the three months ended September 30, 2014 was $40.4 million and the benefit for income taxes for the nine months ended September 30, 2014 was $18.8 million. The benefit from income taxes for the three and nine months ended September 30, 2014 was primarily due to a benefit from the release of valuation allowance on U.S. federal deferred taxes offset by foreign withholding tax and foreign income taxes. The benefit from release of valuation allowance for the three and nine months ended September 30, 2014 is approximately $61.0 million. The provision for income taxes for the three and nine months ended September 30, 2013 was $33.4 million and $25.6 million, respectively, and was largely due to a projected tax benefit from domestic and certain foreign losses as offset by an increase in valuation allowance on U.S. federal deferred taxes. The Company's provision for income taxes is based on its worldwide estimated annualized effective tax rate, except for jurisdictions for which a loss is expected for the year and no benefit can be realized for those losses, and the tax effect of discrete items occurring during the period. The tax for jurisdictions for which a loss is expected and no benefit can be realized for the year is based on actual taxes and tax reserves for the quarter. The increase in the benefit for income taxes for the nine months ended September 30, 2014 as compared to the same period in the prior year is largely attributable to the release in valuation allowance on U.S. federal deferred taxes recognized in the current period as opposed to an increase in valuation allowance that was recognized in the same period last year.
	The need for a valuation allowance requires an assessment of both positive and negative evidence when determining whether it is more likely than not that deferred tax assets are recoverable; such assessment is required on a jurisdiction-by-jurisdiction basis. In making such assessment, significant weight is given to evidence that can be objectively verified. After considering both negative and positive evidence to assess the recoverability of the net deferred tax assets during the third quarter of 2014, the Company determined that it was more likely than not that it would realize the majority of U.S. federal deferred tax assets. This resulted in the reestablishment of U.S. federal deferred tax assets of $53.0 million at September 30, 2014.
	As of September 30, 2014, unrecognized tax benefits approximated $3.0 million, of which $1.4 million would affect the effective tax rate if recognized. At December 31, 2013, unrecognized tax benefits were $5.0 million of which $3.5 million would affect the effective tax rate if recognized. It is reasonably possible that unrecognized tax benefits may decrease by a range of $0.6 million to $0.9 million in the next 12 months due to the expected lapse of statutes of limitation relating to the federal and state research tax credit, certain domestic deductions, as well as foreign tax incentives.
	It is the Company's policy to classify accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. For the three and nine months ended September 30, 2014, the Company recognized an insignificant amount of interest and penalties related to unrecognized tax benefits. As of September 30, 2014 and December 31, 2013, the Company had accrued $0.5 million and $0.6 million, respectively, of interest and penalties related to unrecognized tax benefits.
	At September 30, 2014, the Company's 2008, 2009, and 2011 through 2013 tax years were open and subject to potential examination in one or more jurisdictions. In addition, in the U.S., any net operating losses or credits that were generated in prior years but utilized in an open year may also be subject to examination. The Company recently completed an Internal Revenue Service examination related to its 2008 and 2009 tax returns which resulted in minimal changes to the statement of operations. The Company is not currently under any domestic state income tax examination.

	Lease and Purchase Commitments
	The Company leases office and research facilities and office equipment under operating leases which expire at various dates through 2020. The amounts reflected in the table below are for the aggregate future minimum lease payments under non-cancelable facility and equipment operating leases. Under lease agreements that contain escalating rent provisions, lease expense is recorded on a straight-line basis over the lease term. Rent expense for the three months ended September 30, 2014 and 2013 amounted to $0.9 million and $1.2 million, respectively. Rent expense for the nine months ended September 30, 2014 and 2013 amounted to $2.8 million and $3.6 million, respectively.
	As of September 30, 2014, future minimum lease payments are as follows (in thousands):
		Lease

	Contingencies
	For all legal proceedings, at each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies.
	Litigation Matters
	The Company and its subsidiaries are involved in litigation matters and claims in the normal course of business. In the past, the Company and its subsidiaries have litigated to enforce their respective patents and other intellectual property rights, to enforce the terms of license agreements, to protect trade secrets, to determine the validity and scope of the proprietary rights of others and to defend against claims of infringement or invalidity. The Company expects it or its subsidiaries will be involved in similar legal proceedings in the future, including proceedings regarding infringement of its patents and proceedings to ensure proper and full payment of royalties by licensees under the terms of its license agreements.
	These existing and any future legal actions may harm the Company’s business. For example, they could cause an existing licensee or strategic partner to cease making royalty or other payments to the Company, or to challenge the validity and enforceability of patents owned by the Company’s subsidiaries or the scope of license agreements with the Company’s subsidiaries, and could significantly damage the Company’s relationship with such licensee or strategic partner and, as a result, prevent the adoption of the Company’s other technologies by such licensee or strategic partner. Litigation could also severely disrupt or shut down the business operations of licensees or strategic partners of the Company’s subsidiaries, which in turn would significantly harm ongoing relations with them and cause the Company to lose royalty revenues.
	The costs associated with legal proceedings are typically high, relatively unpredictable and not completely within the Company’s control. These costs may be materially higher than expected, which could adversely affect the Company’s operating results and lead to volatility in the price of its common stock. Whether or not determined in the Company’s favor or ultimately settled, litigation diverts managerial, technical, legal and financial resources from the Company’s business operations. Furthermore, an adverse decision in any of these legal actions could result in a loss of the Company’s proprietary rights, subject the Company to significant liabilities, require the Company to seek licenses from others, limit the value of the Company’s licensed technology or otherwise negatively impact the Company’s stock price or its business and consolidated financial position, results of operations or cash flows.

	SEGMENT AND GEOGRAPHIC INFORMATION
	In the first quarter of 2014, following the Company’s actions to cease manufacturing operations in the DigitalOptics business, the Company determined that it operates its business in one operating segment, focused on the monetization of intellectual property, both internally developed and acquired, through royalties, licenses and other means. Previously, the Company operated in two operating segments – Intellectual Property and DigitalOptics. Our chief operating decision maker is our Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance.
	A significant portion of the Company’s revenues is derived from licensees headquartered outside of the U.S., principally in Asia, and it is expected that these revenues will continue to account for a significant portion of total revenues in future periods. The table below lists the geographic revenues from continuing operations for the periods indicated (in thousands):

	RESTRUCTURING, IMPAIRMENT OF LONG-LIVED ASSETS AND OTHER CHARGES
	In January 2014, the Company announced the cessation of all mems|cam manufacturing operations. As part of these efforts, the Company is undertaking a workforce reduction of over 300 employees and is in the process of closing its facilities in Arcadia, California, Rochester, New York and in Taiwan and Japan. These actions triggered a $32.8 million impairment of manufacturing equipment, a $4.8 million impairment of intangible assets, purchase obligations of $9.8 million for inventory and equipment, and impairments of IT related assets of $2.1 million in the fourth quarter of 2013. Additionally, in the first nine months of 2014, the Company incurred additional restructuring and other charges including $3.6 million of employee severance. In this document, the operations and financial results of the mems|cam operations are considered discontinued operations. For more information regarding these actions, see Note 5 - "Discontinued Operations" and Note 7 – "Goodwill and Identified Intangible Assets."

Accounting Policies [Abstract]	'
Basis of Accounting	'
	The accompanying interim unaudited condensed consolidated financial statements as of September 30, 2014 and 2013, and for the three and nine months then ended, have been prepared by the Company in accordance with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”) for interim financial information. The amounts as of December 31, 2013 have been derived from the Company’s annual audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary (consisting of normal recurring adjustments) to state fairly the financial position of the Company and its results of operations and cash flows as of and for the periods presented. These financial statements should be read in conjunction with the annual audited financial statements and notes thereto as of and for the year ended December 31, 2013, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, filed on March 3, 2014 (the “Form 10-K”).
Reclassification	'
	Reclassification
	Certain reclassifications have been made to prior period balances in order to conform to the current period’s presentation. In addition, certain operations are being classified in discontinued operations, and these items have been correspondingly reclassified for all prior periods presented. See Note 5 - “Discontinued Operations.”
New Accounting Pronouncement	'
	Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry-forward, a Similar Tax Loss, or a Tax Credit Carry-forward Exists.” This ASU provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carry forward or a tax credit carry forward exists. Under the ASU, the Company’s unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward or a tax credit carry forward. This ASU applies to all entities that have unrecognized tax benefits when a net operating loss carry-forward, a similar tax loss, or a tax credit carry-forward exists at the reporting date. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Company's financial statements.
	Recent Accounting Pronouncements
	In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification Topic No. 718, “Compensation - Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of ASU 2014-12 is not expected to have a material effect on the Company’s unaudited condensed consolidated financial statements or disclosures.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (“ASU 2014-09”), which provides guidance for revenue recognition. ASU 2014-09 affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets and supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition,” and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” ASU 2014-09’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is effective for the Company beginning January 1, 2017 and, at that time, the Company may adopt the new standard under the full retrospective approach or the modified retrospective approach. Early adoption is not permitted. The Company is currently evaluating the method and impact the adoption of ASU 2014-09 will have on the Company’s unaudited condensed consolidated financial statements and disclosures.
	In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 changes the criteria for reporting a discontinued operation. Under the new pronouncement, a disposal of a part of an organization that has a major effect on its operations and financial results is a discontinued operation. The Company is required to adopt ASU 2014-08 prospectively for all disposals or components of its business classified as held for sale during fiscal periods beginning after December 15, 2014. The Company is currently evaluating what impact, if any, the adoption of this ASU will have on the presentation of the Company's financial statements.

	(2) As part of the restructuring of its DigitalOptics business, the Company incurred $5.2 million in workforce and corporate overhead reductions and $13.7 million impairment of long-lived assets, which included an $8.7 million charge due to the abandonment of patents and technology which caused a revision of the useful life estimate of these patent and technology assets thus fully impairing them.

	(1) The decrease in the September 30, 2014 balance from the December 31, 2013 balance results from the sale of land and building assets of our DigitalOptics operations in Charlotte in August 2014, partially offset by the inclusion in discontinued operations of assets related to our former mems|cam manufacturing operations since January 2014, whereas they were included in continuing operations as of December 31, 2013. The mems/cam assets are classified as held for sale.
	(2) The increase in the September 30, 2014 balances from the December 31, 2013 balances is related to the cessation of all mems|cam manufacturing operations with the liabilities of those operations being included in discontinued operations since 2014, whereas they were included in continuing operations as of December 31, 2013. At September 30, 2014, this amount is primarily related to lease obligations, purchase commitments and employee severance.

[1]	As noted above, in January 2014, the Company announced the cessation of all mems|cam manufacturing operations. As part of these actions, the Company incurred severance and accelerated lease obligations and other charges. See Note 14 for additional information.
[2]	As part of the restructuring of its DigitalOptics business, the Company incurred $5.2 million in workforce and corporate overhead reductions and $13.7 million impairment of long-lived assets, which included an $8.7 million charge due to the abandonment of patents and technology which caused a revision of the useful life estimate of these patent and technology assets thus fully impairing them.

[1]	The decrease in the September 30, 2014 balance from the December 31, 2013 balance results from the sale of land and building assets of our DigitalOptics operations in Charlotte in August 2014, partially offset by the inclusion in discontinued operations of assets related to our former mems|cam manufacturing operations since January 2014, whereas they were included in continuing operations as of December 31, 2013. The mems/cam assets are classified as held for sale.
[2]	The increase in the September 30, 2014 balances from the December 31, 2013 balances is related to the cessation of all mems|cam manufacturing operations with the liabilities of those operations being included in discontinued operations since 2014, whereas they were included in continuing operations as of December 31, 2013. At September 30, 2014, this amount is primarily related to lease obligations, purchase commitments and employee severance.
