The Company And Basis Of Presentation	'
	THE COMPANY AND BASIS OF PRESENTATION
	Tessera Technologies, Inc. (the “Company”) is a holding company with operating subsidiaries in two segments: Intellectual Property and DigitalOptics.
	The Company's Intellectual Property segment, managed by Tessera Intellectual Property Corp., generates revenue from manufacturers and other implementers that use our technology. The segment includes Tessera, Inc. and Invensas Corporation (“Invensas”). Tessera, Inc. pioneered chip-scale packaging solutions, which it licenses to the semiconductor industry. Invensas develops and acquires interconnect solutions and intellectual property in areas such as mobile computing and communications, memory and data storage, and 3-D Integrated Circuit (“3DIC”) technologies.
	DigitalOptics Corporation and its subsidiaries ("DOC") manage the DigitalOptics segment. DOC designs and manufactures imaging systems for smartphones, generating revenue through product sales and software license fees and royalties. DigitalOptics' expertise in optics, camera modules, Micro-Electro Mechanical Systems (“MEMS”), and image processing enable it to deliver products that expand the boundaries of smartphone photography.
	The accompanying interim unaudited condensed consolidated financial statements as of September 30, 2013 and 2012, 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, 2012 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, 2012, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, filed on March 1, 2013 (the “Form 10-K”).
	The results of operations for the three and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the full year ended December 31, 2013 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 6 - “Discontinued Operations.”

	RECENT ACCOUNTING PRONOUNCEMENTS
	Adopted
	In July 2012, the Financial Accounting Standards Board ("FASB") issued ASU 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, which is intended to reduce the complexity and cost of performing a quantitative test for impairment of indefinite-lived intangible assets by permitting an entity the option to perform a qualitative evaluation about the likelihood that an indefinite-lived intangible asset is impaired in order to determine whether it should calculate the fair value of the asset. The update also improves previous guidance by expanding upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. The Company adopted this guidance in fiscal year 2013 on a prospective basis. For further information on intangible asset impairment, see Note 8 – "Goodwill and Identified Intangible Assets." The adoption of this ASU did not have a material impact on the Company’s financial statements.
	In December 2011, the FASB issued ASU 2011-11, Balance Sheet (Topic 210): Disclosure about Offsetting Assets and Liabilities, which requires an entity to include additional disclosures about financial instruments and transactions eligible for offset in the statement of financial position, as well as financial instruments subject to a master netting agreement or similar arrangement. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this ASU did not have a material impact on the Company’s financial statements.
	In February 2013, the FASB issued amendments to the FASB Accounting Standards Codification relating to the reporting of reclassifications out of accumulated other comprehensive income. The amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The Company adopted these amendments in the first quarter of fiscal year 2013 on a prospective basis. The adoption of this ASU did not have a material impact on the Company’s financial statements.

	Short-term investments									338,801
	Total marketable securities									$	395,583
	At September 30, 2013 and December 31, 2012, the Company had $376.8 million and $442.6 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 $44.4 million and $47.0 million at September 30, 2013 and December 31, 2012, 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, 2013 and 2012.
	Unrealized gains (net of unrealized losses) of $0.1 million, net of tax, as of September 30, 2013, were related to a temporary decrease 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, 2013 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, 2013 and 2012, 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, 2013 and December 31, 2012, which have been in a continuous unrealized loss position, aggregated by investment category and length of time (in thousands):

	DISCONTINUED OPERATIONS
	In June 2012, DOC, a subsidiary of Tessera Technologies, Inc., completed its acquisition of certain assets of Vista Point Technologies, from Flextronics International Ltd. (the "Zhuhai Transaction"). At the time of the closing of the Zhuhai Transaction, the Company intended to use the acquired assets and related manufacturing business to accelerate its strategy of building the DigitalOptics segment 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 the facility in Zhuhai, China (the "Zhuhai Facility"). 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 microoptic sub-assemblies. The Company determined these offerings were no longer part of its long-term strategy for the DigitalOptics business. As a result, on August 9, 2013, the Company sold all of the related assets of the Micro-Optics business to a buyer in exchange for $14.9 million in cash which resulted in a disposal gain of $8.7 million, and is included in the net loss from discontinued operations. The Company retained ownership of the related land and building and certain fabrication assets for this facility, which is being leased to the buyer.
	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 statements of operations and the balance sheets for all periods presented.

Fair Value	'
	FAIR VALUE
	The Company follows the authoritative guidance fair value measurement and the fair value option 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, 2013 (in thousands):

	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 its plans to close the Zhuhai Facility in March 2013. This decision triggered an impairment review of the related goodwill and purchased intangible assets recorded in connection with the Zhuhai Transaction (see Note 6 – "Discontinued Operations," for additional detail regarding the Zhuhai Transaction). 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, all of which was included in the DigitalOptics segment.

	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, 2013, in the calculation of net loss per share, all 2.2 million shares 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.
	For the three and nine months ended September 30, 2012, in the calculation of net loss per share, all 6.5 million shares 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.

	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. As of September 30, 2013, the Company had repurchased a total of approximately 904,000 shares of common stock, since inception of the plan, at an average price of $17.16 per share for a total cost of $15.5 million. As of December 31, 2012, the Company had repurchased a total of approximately 645,000 shares of common stock, since inception of the plan, at an average price of $16.26 per share for a total cost of $10.5 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, 2013, the total amount available for repurchase was $84.5 million, which excludes the $50.0 million increase in the amount authorized noted above. The Company plans to continue to execute authorized repurchases from time to time under the plan.
	In May 2013, in connection with the announcement of a special dividend under a revised dividend policy, the Company also announced that it expected to execute at least $16 million of stock repurchases through its stock repurchase program over the ensuing four quarters. Under this program, the Company completed repurchases of common stock totaling $5.0 million during the third quarter of 2013.

	The Company uses the Black-Scholes option pricing model to determine the estimated fair value of stock-based awards. 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 by annualizing the cash dividend declared by the Board for the current quarter 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 record 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-13			30-Sep-12			30-Sep-13	30-Sep-12
	Expected life (in years)	5			3.7			5	3.7

	INCOME TAXES
	The provision for income taxes for the three months ended September 30, 2013 was $40.5 million and the provision for income taxes for the nine months ended September 30, 2013 was $21.9 million. The provision for income taxes for the three months and nine months ended September 30, 2013 was primarily due to an increase in valuation allowance on federal deferred taxes in the third quarter as a result of the determination that it was more likely than not that the deferred tax assets would not be realized. The Company recorded a valuation allowance against substantially all of its federal deferred tax assets as it concluded such assets were no longer fully realizable. 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 Company's net deferred tax assets during the third quarter of 2013, the Company determined that it was not more likely than not it would realize the full value of its federal deferred tax assets given current uncertainties regarding the timing of profits that has caused the Company to be in a cumulative three year loss position as of the end of the third quarter of 2013 and, as projected, for the end of 2013. The Company will continue to monitor the likelihood that it will be able to recover its deferred tax assets in the future. This determination includes objectively verifiable positive evidence that outweighs potential negative evidence.
	The provision for income taxes for the three and nine months ended September 30, 2012 was $3.7 million and $6.6 million, respectively, and was largely comprised of a projected tax expense for domestic and selected foreign jurisdictions as well as foreign withholding and income 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.
	As of September 30, 2013, unrecognized tax benefits approximated $5.1 million, of which $3.6 million would affect the effective tax rate if recognized. At December 31, 2012, unrecognized tax benefits were $4.8 million of which $3.6 million would affect the effective tax rate if recognized. It is reasonably possible that unrecognized tax benefits may decrease by a range of $2.9 million to $3.0 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, 2013 and 2012, the Company recognized an insignificant amount of interest and penalties related to unrecognized tax benefits. As of September 30, 2013 and December 31, 2012, the Company had accrued $0.6 million and $0.5 million, respectively, of interest and penalties related to unrecognized tax benefits.
	At September 30, 2013, the Company's 2008 through 2012 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 is currently under Internal Revenue Service examination related to its 2008 and 2009 tax returns. The Company is not currently under any domestic state income tax examination.

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, 2013 and 2012 was $1.2 million and $1.1 million, respectively. Rent expense for the nine months ended September 30, 2013 and 2012, was $3.6 million and $2.8 million, respectively.
	As of September 30, 2013, future minimum lease payments are as follows (in thousands):

	Contingencies
	For all legal proceedings described below, 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. The Company is currently unable to predict the final outcome of these lawsuits and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. An adverse decision in any of these proceedings could significantly harm the Company’s business and consolidated financial position, results of operations or cash flows.
	Powertech Technology Inc. v. Tessera, Inc., Civil Action No. 4:11-06121-CW (N.D. Cal.)
	On December 6, 2011, Powertech Technology, Inc. ("PTI") filed a complaint against Tessera, Inc. in the U.S. District Court for the Northern District of California. PTI's complaint seeks a declaratory judgment that PTI has the right to terminate its license with Tessera, Inc. as of December 6, 2011. The complaint also seeks damages for breach of contract in the amount of all royalties paid to Tessera, Inc. since December 7, 2007, purportedly totaling at least $200 million, in addition to an accounting of PTI's damages, an accounting of Tessera, Inc.'s revenue from PTI, prejudgment interest, costs and fees, and other relief deemed proper. Tessera, Inc. disagrees with the assertions made by PTI in the complaint regarding breach of contract, and believes the likelihood that Tessera, Inc. will be required to return already-paid royalties is remote.
	On December 15, 2011, the case was related to Powertech Technology Inc. v. Tessera, Inc., Civil Action No. 4:10-00945-CW (N.D. Cal.).
	On December 30, 2011, Tessera, Inc. filed a motion to dismiss the complaint for failure to state a claim upon which relief can be granted and a special motion to strike pursuant to California's anti-SLAPP statute. The Court denied Tessera, Inc.'s motions on May 21, 2012.
	The district court held a Case Management Conference on January 4, 2012. The court issued a Minute Order and Case Management Order dated January 4, 2012, setting, among other things, a fact discovery cut-off date of January 18, 2013 and a trial date of April 7, 2014.
	On June 3, 2012, PTI filed an amended complaint against Tessera, Inc., adding claims for fraud and deceit, patent misuse, and a declaratory judgment interpreting PTI's license agreement with Tessera, Inc. In addition to the damages sought by PTI's original complaint, the amended complaint seeks punitive damages for fraud, termination of the Tessera, Inc. license as of September 24, 2010, recovery of all royalties paid on wBGA products since September 24, 2010, and an order “enjoining Tessera, Inc. and directing that Tessera, Inc. may not proceed against any party,… under any Tessera Patent as defined by Exhibit A to the TCC License with all amendments, supplements, and additions through September 28, 2010 until Tessera has first paid PTI all of the royalties paid on wBGA products by PTI since September 24, 2010, presently estimated to be $40 million.” Tessera, Inc. filed a motion to dismiss PTI's claim for patent misuse and to strike portions of PTI's claim for fraud on June 19, 2012. On August 10, 2012, the Court granted in part and denied in part Tessera, Inc.'s motion, specifically dismissing the patent misuse claim and striking the fraud claim, and granted PTI leave to file an amended and supplemental complaint.
	On June 29, 2012, PTI sent a letter to Tessera, Inc. purporting to terminate the TCC License Agreement between PTI and Tessera, Inc. as of June 30, 2012.
	On August 24, 2012, PTI filed a third amended complaint. In addition to the claims and recovery alleged in its earlier complaints, the third amended complaint contained an amended fraud claim and an amended patent misuse claim. The new fraud claim sought damages at least in the amount of the royalty payments made to Tessera, Inc. after December 7, 2007, and punitive damages. The new patent misuse claim asked for declarations that Tessera has engaged in patent misuse, that the agreement is unenforceable against PTI until Tessera, Inc. has purged the patent misuse, and that the Tessera, Inc. patents are unenforceable against PTI until Tessera, Inc. has purged the patent misuse. Tessera, Inc. answered that complaint on September 10, 2012. Also on September 10, 2012, Tessera, Inc. filed counterclaims against PTI for breach of contract, breach of the implied covenant, fraud, negligent misrepresentation, declaratory judgment of indemnification, and declaratory judgment regarding PTI's asserted termination of the agreement.
	On July 20, 2012, PTI filed a motion for summary judgment on PTI's first claim for relief in this case. On August 9, 2012, Tessera, Inc. filed an opposition to PTI's motion and filed its own motion for summary judgment on PTI's first, second and third claims on the ground, among others, that under the unambiguous language of the agreement Tessera, Inc. did not breach the agreement by filing and pursing its claims in the '630 ITC Action.
	On September 20, 2012, the court heard arguments on PTI's July 20, 2012 summary judgment motion and Tessera, Inc.'s August 9, 2012 summary judgment motions and took the motions under submission. On October 2, 2012, the parties stipulated to the court's taking the motions off calendar. On August 1, 2013, the court denied both parties' summary judgment motions without prejudice to renew on the presently-set date for hearing summary judgment motions of December 12, 2013. On October 11, 2013, PTI filed a motion for summary judgment. Tessera, Inc. filed its opposition and cross-motion for summary judgment on November 1, 2013.
	On October 23, 2012, the Court granted PTI leave to file its fourth amended and supplemental complaint. PTI's fourth amended complaint adds an allegation to PTI's claim for declaratory relief seeking the recovery and return of royalty payments made to Tessera, Inc. from at least March 2010 in an amount exceeding $130 million and continues to seek the recovery sought in PTI's third amended complaint.
	On February 6, 2013, the parties stipulated to Tessera, Inc.'s filing Amended Counterclaims adding claims for fraudulent transfer, intentional interference with prospective economic advantage and negligent interference with economic advantage, and seeking damages, punitive damages, to void the fraudulent transfer of PTI's business to Macrotech Technology Inc. (“MTI”), to enjoin PTI from any such transfers in the future, and attorneys' fees and costs. The parties further stipulated to PTI's filing of a response to Tessera, Inc.'s counterclaims adding affirmative defenses of nonoccurrence of conditions precedent, unilateral contract, and mistake. On March 8, 2013, the Court gave Tessera, Inc. leave to file the Amended Counterclaims. On March 21, 2013, PTI filed an answer to the Amended Counterclaims.
	On March 19, 2013, the parties stipulated to Tessera, Inc.'s Second Amended Counterclaims to add MTI as a party, and to add Tessera, Inc.'s claims of intentional interference with prospective economic advantage, negligent interference with economic advantage, inducing breach of contract, and constructive trust against MTI, which seek damages, punitive damages, attorneys' fees and costs, and an order that the royalties owed by MTI be held in a trust for Tessera, Inc. On March 21, 2013, the Court entered an order giving Tessera, Inc. leave to file the Second Amended Counterclaims. On March 28, 2013, PTI and MTI filed answers to the Second Amended Counterclaims.
	Contingency fee dispute for the case of Tessera Technologies, Inc. v. Hynix Semiconductor Inc. et. al, Case No. 1-06-CV-076688 (Cal. Super. Ct.)
	Tessera Technologies, Inc. has a dispute with its former counsel Susman Godfrey L.L.P. (“Susman”) over the amount due to Susman, if any, as a contingency fee for Susman's work in the matter of Tessera Technologies, Inc. v. Hynix Semiconductor Inc.  Susman has requested arbitration of the dispute. On March 25, 2013 the arbitrator set an arbitration hearing date of February 3, 2014.
	Other Litigation Matters
	In addition to the foregoing matters, the Company and its subsidiaries are involved in other 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 either or both of the Company’s business segments, and may hinder the Company’s ability to independently optimize each business segment. 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 Intellectual Property or DigitalOptics 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 Reporting [Abstract]	'
Segment And Geographic Information	'
	SEGMENT AND GEOGRAPHIC INFORMATION
	The Company has two reportable segments: Intellectual Property and DigitalOptics. Corporate Overhead includes certain operating amounts such as finance, IT, HR, legal, business development and other administrative services that are not allocated to the reportable segments because these operating amounts are not considered in evaluating the operating performance of the Company’s business segments.
	The Company's Interim Chief Executive Officer is also the Chief Operating Decision Maker ("CODM") as defined by the authoritative guidance on segment reporting. Additionally, the DOC segment has its own president. The Company has organized its reporting units to align with the vision of the CODM.
	The Intellectual Property segment, managed by Tessera Intellectual Property Corp., generates revenue from manufacturers and other implementers that use our technology. The segment includes Tessera, Inc. and Invensas. Tessera, Inc. pioneered chip-scale packaging solutions, which it licenses to the semiconductor industry. Invensas develops and acquires interconnect solutions and intellectual property in areas such as mobile computing and communications, memory and data storage, and 3DIC technologies.
	DOC operates the DigitalOptics segment. DOC designs and manufactures imaging systems for smartphones, generating revenue through product sales and software license fees and royalties. DOC’s expertise in optics, camera modules, MEMS, and image processing enable it to deliver products that expand the boundaries of smartphone photography.
	The Company does not identify or allocate assets by reportable segment, nor does the CODM evaluate reportable segments using discrete asset information. Reportable segments do not record inter-segment revenues and accordingly there are none to report. The Company does not allocate other income and expense to reportable segments. Although the CODM uses operating income to evaluate reportable segments, operating costs included in one segment may benefit other segments.
	The following table sets forth the Company’s segment revenues, operating expenses and operating income (loss) from continuing operations for the three and nine months ended September 30, 2013 and 2012 (in thousands):

Restructuring, Impairment of Long-Lived Assets And Other Charges	'
	RESTRUCTURING, IMPAIRMENT OF LONG-LIVED ASSETS AND OTHER CHARGES
	Beginning in 2011, the Company initiated a reorganization of its DigitalOptics segment. These actions were intended to refocus its DigitalOptics Corporation ("DOC") business strategy to achieve the full potential of its differentiated imaging technology while reducing costs. In August 2011, the Company announced a commitment to undertake a workforce reduction at its Yokohama, Japan development facility and to close that facility in order to optimize the Company’s operations. Expenses incurred as a result of these activities consisted of severance, costs related to the continuation of certain employee benefits and expenses related to the closure of the facility and termination of the operating lease, and are recorded in restructuring and other charges on the statement of operations. Total restructuring and other charges related to these activities were $5.2 million, all of which were expensed in the year ended December 31, 2011 and these activities were completed during the first quarter of 2012. In November 2012, the Company announced a restructuring of its DigitalOptics segment in Tel Aviv, Israel. In connection with this effort, DigitalOptics reduced its workforce and ceased operations at its facility in Tel Aviv, Israel and incurred total charges of $2.5 million in the fourth quarter of 2012.
	In 2013, the Company continued reorganizing the DigitalOptics segment by closing its manufacturing operation in Zhuhai, China and selling a significant portion of the assets of the Company's Micro-Optics business based in Charlotte, North Carolina. For the first nine months of 2013, the Company incurred cumulative charges, which includes continuing and discontinued operations in total, of $6.1 million in severance and $17.9 million in impairment of long-lived assets and other charges. Refer to the table below for more details of the restructuring, impairment of long-lived assets and other charges which are presented on a combined continuing and discontinued operations basis.
	The Company did not incur restructuring charges in the nine months ended September 30, 2012. Information with respect to restructuring, impairment of long-lived assets and other charges as of September 30, 2013 is as follows (in thousands):

	(1) Employee severance recorded in the first quarter of 2013 was $2.1 million, of which $0.7 million was recorded in discontinued operations relating to the closure of the Zhuhai Facility. Impairment of long-lived assets and other of $13.7 million in the three months ended March 31, 2013 included impairment charges of $3.4 million from discontinued operations and $10.3 million from continuing operations. Impairment from discontinued operations included $1.8 million in manufacturing equipment assets held for sale resulting from the closure of the Zhuhai Facility, and impairment charges of $0.7 million relating to customer relationships and $0.9 million relating to patents acquired from the Zhuhai Transaction. Impairments from continuing operations included a $0.3 million impairment of research and development equipment relating to the closure of the facility in Tel Aviv, Israel, $1.3 million of manufacturing equipment assets held for sale relating to the Taiwan operation, and an $8.7 million charge due to the abandonment of patents and technology which caused a revision of the useful life estimate of these patents and technology assets thus fully impairing them (see Note 8 – "Goodwill and Identified Intangibles Assets" for more information about the accelerated amortization of existing technology).
	(2) Restructuring and other charges totaled $6.5 million in the three months ended June 30, 2013 of which $6.0 million was included in continuing operations and $0.5 million was classified in discontinued operations, which included $0.2 million of severance payments relating to the Zhuhai operation and $0.3 million of severance payments relating to the Charlotte operation.

	(3) Restructuring and other charges totaled $1.8 million in the three months ended September 30, 2013 of which $4.4 million of expenses was recorded in continuing operations and a net gain of $2.6 million was classified in discontinued operations (see Note 6 – "Discontinued Operations" for more details about restructuring and other charges in discontinued operations). Employee severance in the three months ended September 30, 2013 consisted of $2.9 million of severance payments primarily relating to the sale of the Micro-Optics business in Charlotte, North Carolina. On a continuing and discontinued operation basis as a whole, the net gain of $1.2 million of impairment of long-lived assets and other charges in the three months ended September 30, 2013 included a $3.4 million impairment of assets relating to the Charlotte operation, $1.5 million in consulting fees for the sale of Charlotte assets, $0.9 million impairment of trade name intangibles relating to the Charlotte operation, $0.5 million impairment of a lease as a result of the closure of the Zhuhai facility, and impairment charges of $0.6 million relating to fixed assets in the DOC business, offset by an $8.7 million gain on sale of assets relating to the Charlotte operation.

[1]	Restructuring and other charges totaled $1.8 million in the three months ended September 30, 2013 of which $4.4 million of expenses was recorded in continuing operations and a net gain of $2.6 million was classified in discontinued operations (see Note 6 – "Discontinued Operations" for more details about restructuring and other charges in discontinued operations). Employee severance in the three months ended September 30, 2013 consisted of $2.9 million of severance payments primarily relating to the sale of the Micro-Optics business in Charlotte, North Carolina. On a continuing and discontinued operation basis as a whole, the net gain of $1.2 million of impairment of long-lived assets and other charges in the three months ended September 30, 2013 included a $3.4 million impairment of assets relating to the Charlotte operation, $1.5 million in consulting fees for the sale of Charlotte assets, $0.9 million impairment of trade name intangibles relating to the Charlotte operation, $0.5 million impairment of a lease as a result of the closure of the Zhuhai facility, and impairment charges of $0.6 million relating to fixed assets in the DOC business, offset by an $8.7 million gain on sale of assets relating to the Charlotte operation.
[2]	Employee severance recorded in the first quarter of 2013 was $2.1 million, of which $0.7 million was recorded in discontinued operations relating to the closure of the Zhuhai Facility. Impairment of long-lived assets and other of $13.7 million in the three months ended March 31, 2013 included impairment charges of $3.4 million from discontinued operations and $10.3 million from continuing operations. Impairment from discontinued operations included $1.8 million in manufacturing equipment assets held for sale resulting from the closure of the Zhuhai Facility, and impairment charges of $0.7 million relating to customer relationships and $0.9 million relating to patents acquired from the Zhuhai Transaction. Impairments from continuing operations included a $0.3 million impairment of research and development equipment relating to the closure of the facility in Tel Aviv, Israel, $1.3 million of manufacturing equipment assets held for sale relating to the Taiwan operation, and an $8.7 million charge due to the abandonment of patents and technology which caused a revision of the useful life estimate of these patents and technology assets thus fully impairing them (see Note 8 – "Goodwill and Identified Intangibles Assets" for more information about the accelerated amortization of existing technology).
