INTERDIGITAL, INC. AND SUBSIDIARIES

1. BASIS OF PRESENTATION:

     In the opinion of management, the accompanying unaudited, condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the financial position of InterDigital, Inc. (individually and/or collectively with its subsidiaries referred to as “InterDigital,” the “Company,” “we,” “us” or “our,” unless otherwise indicated) as of September 30, 2010, and the results of our operations for the three and nine months ended September 30, 2010 and 2009 and our cash flows for the nine months ended September 30, 2010 and 2009. The accompanying unaudited, condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, accordingly, do not include all of the detailed schedules, information and notes necessary to state fairly the financial condition, results of operations and cash flows in conformity with generally accepted accounting principles (“GAAP”). The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP for year-end financial statements. Therefore, these financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009 (our “2009 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 26, 2010. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. We have one reportable segment.

     The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Change in Classification

     The classification of certain prior period amounts have been changed to conform to the current year presentation.

Change in Accounting Policies

     There have been no material changes in our existing accounting policies from the disclosures included in our 2009 Form 10-K.

New Accounting Guidance

Accounting Standards Updates: Revenue Arrangements with Multiple Deliverables

     In September 2009, the Financial Accounting Standards Board (“FASB”) finalized revenue recognition guidance for Revenue Arrangements with Multiple Deliverables. By providing another alternative for determining the selling price of deliverables, the Accounting Standard Update related to revenue arrangements with multiple deliverables will allow companies to allocate arrangement consideration in multiple deliverable arrangements in a manner that better reflects the transaction’s economics. In addition, the residual method of allocating arrangement consideration is no longer permitted under this new guidance. This guidance is effective for fiscal years beginning on or after June 15, 2010. However, adoption is permitted as early as the interim period ended September 30, 2009. The guidance may be applied either prospectively from the beginning of the fiscal year for new or materially modified arrangements or retrospectively. We have not yet adopted this guidance. We believe that revenue recognition related to new agreements with multiple elements may be recorded earlier under the new guidance than under existing guidance.

Accounting Standards Updates: Fair Value Measurements

     In January 2010, the FASB issued authoritative guidance on improving disclosures about fair value measurements. This guidance requires new disclosures about transfers in and out of Level 1 and 2 measurements and separate disclosures about activity relating to Level 3 measurements. In addition, this guidance clarifies existing fair value disclosures about the level of disaggregation and the input and valuation techniques used to measure fair value. The guidance only relates to disclosure and does not impact the Company’s consolidated financial statements. The Company adopted this guidance in first quarter 2010. There was no significant impact to the Company’s disclosures upon adoption, as the Company does not have any such transfers.

2. SIGNIFICANT EVENTS:

Patent Licensing

     In first quarter 2010, we entered into a worldwide, non-exclusive patent license agreement with Casio Hitachi Mobile Communications Co., Ltd. (“CHMC”). The patent license agreement covers the sale by CHMC of all wireless end-user terminal devices compliant with 2G and 3G cellular standards through June 1, 2010. In addition, in first quarter 2010, we identified additional royalty obligations in a routine audit of an existing customer. In first nine months 2010, we have recognized revenue totaling $39.9 million, including $35.7 million related to past sales, in connection with these two items.

Technology Solutions

     In third quarter 2010, we entered into a technology license agreement to provide our SlimChip^TM 2G and 3G modem technology to a mobile chipset manufacturer in mainland China. Under the non-exclusive, royalty-bearing technology delivery agreement, InterDigital will license a dual mode core with 2G and 3G physical layer — inclusive of HSPA, compliant with the UMTS 3GPP Release 6 standard — and provide engineering support. InterDigital will receive milestone-based payments and will be compensated on a per-unit royalty basis on sales of products containing the delivered technology.

     We are accounting for portions of this and other technology solutions agreements using the proportional performance method. During third quarter 2010 and third quarter 2009, we recognized related revenue of $3.2 million and $0.0 million, respectively. As of September 30, 2010 and December 31, 2009, our deferred revenue balances associated with our technology solutions agreements accounted for using proportional performance were $2.9 million and $0.0 million, respectively. We did not have any amounts of unbilled accounts receivable at September 30, 2010 or December 31, 2009.

3. REPOSITIONING:

     On March 30, 2009, we announced a repositioning plan that included the expansion of our technology development and licensing business, the cessation of further ASIC development of our SlimChip modem and efforts to monetize the SlimChip technology investment through IP licensing and technology sales. In connection with the repositioning, the Company incurred a charge of $38.6 million during 2009, of which $37.0 million was recognized in first nine months 2009. Of the total charge of $38.6 million, approximately $30.6 million represents long-lived asset impairments for assets used in the product and product development, including $21.2 million of acquired intangible assets and $9.4 million of property, equipment, and other assets.

     In addition, the repositioning resulted in a reduction in force of approximately 100 employees across the Company’s three locations, the majority of which were terminated effective April 3, 2009. Approximately $8.0 million of the total repositioning charge represents cash obligations associated with severance and contract termination costs. Substantially all of the remaining contract termination costs are scheduled to be paid by the end of the calendar year.

     We did not incur any additional repositioning charges in first nine months 2010, nor do we expect to incur any additional repositioning costs in the future in conjunction with the wind-down activities related to our SlimChip product development.

     The following table provides information related to our accrued liability for repositioning costs through September 30, 2010, which is included on our balance sheet within Other accrued expenses (in thousands):

		Asset				Severance and				Contract
		Impairments				Related Costs				Termination Costs				Total
Expected repositioning charge		$	30,568			$	3,893			$	4,143			$	38,604

September 30, 2010		$	—			$	—			$	304			$	304

4. INCOME TAXES:

     In first nine months 2010, our effective tax rate was approximately 35.3% based on the statutory federal tax rate net of discrete state and foreign taxes. During first nine months 2009, our effective tax rate was approximately 35.5% based on the statutory federal tax rate net of discrete state and foreign taxes.

     During first nine months 2010 and first nine months 2009, we paid approximately $35.2 million and $40.7 million, respectively, of foreign withholding tax. We previously accrued the first nine months 2010 payment and established a corresponding deferred tax asset representing the associated foreign tax credit that we expect to utilize to offset future U.S. federal income taxes.

     Our future book tax expense may also be affected by charges associated with any share-based tax shortfalls that may occur. However, we cannot predict if, when or to what extent this will affect our future tax expense. If, in the course of future tax planning, we identify tax saving

opportunities that entail amending prior year returns in order to avail ourselves fully of credits that we previously considered unavailable to us, we will recognize the benefit of the credits in the period in which they are both identified and quantified, thereby reducing the book tax expense in that period.

5. NET INCOME PER SHARE:

     The following table sets forth a reconciliation of the shares and the net income applicable to common shareholders used in the basic and diluted net income per share computations (in thousands, except per share data):

		For the Three Months Ended September 30,

		Basic				Diluted				Basic				Diluted
Numerator:

Denominator:
Weighted-average shares outstanding: Basic			43,889				43,889				43,353				43,353
Dilutive effect of stock options							567								843

Dilutive effect of stock options							(0.03	)							(0.02	)
Net income: Diluted						$	2.66							$	1.08

     For both three months and nine months ended September 30, 2010, options to purchase less than 0.1 million shares of common stock were excluded from the computation of diluted earnings per share because the exercise prices of these options were greater than the weighted-average market price of our common stock during these periods and, therefore, their effect would have been anti-dilutive.

     For three months and nine months ended September 30, 2009, options to purchase approximately 0.7 million and 0.5 million shares of common stock, respectively, were excluded from the computation of diluted earnings per share because the exercise prices of these options were greater than the weighted-average market price of our common stock during these periods and, therefore, their effect would have been anti-dilutive.

6. LITIGATION AND LEGAL PROCEEDINGS:

Nokia United States International Trade Commission (“USITC” or the “Commission”) Proceeding and Related Delaware District Court and Southern District of New York Proceedings

     In August 2007, InterDigital filed a USITC complaint against Nokia Corporation and Nokia, Inc. (collectively, “Nokia”) alleging that Nokia engaged in an unfair trade practice by selling for importation into the United States, importing into the United States, and selling after importation into the United States, certain 3G mobile handsets and components that infringe two of InterDigital’s patents. In November and December 2007, a third patent and fourth patent, respectively, were added to our complaint against Nokia. The complaint seeks an exclusion order barring from entry into the United States infringing 3G mobile handsets and components that are imported by or on behalf of Nokia. Our complaint also seeks a cease-and-desist order to bar further sales of infringing Nokia products that have already been imported into the United States.

     In addition, on the same date as our filing of the USITC action referenced above, we also filed a complaint in the Delaware District Court alleging that Nokia’s 3G mobile handsets and components infringe the same two InterDigital patents identified in the original USITC complaint. This Delaware action was stayed on January 10, 2008, pursuant to the mandatory, statutory stay of parallel district court proceedings at the request of a respondent in a USITC investigation. Thus, this Delaware action is stayed with respect to the patents in this case until the USITC’s determination on these patents becomes final, including any appeals. The Delaware District Court permitted InterDigital to add to the stayed Delaware action the third and fourth patents InterDigital asserted against Nokia in the USITC action. Nokia, joined by Samsung Electronics Co., Ltd. (“Samsung”), moved to consolidate the Nokia USITC proceeding with an investigation we had earlier initiated against Samsung in the USITC. On October 24, 2007, the Honorable Paul J. Luckern, the Administrative Law Judge overseeing the two USITC proceedings against Samsung and Nokia, respectively, issued an order to consolidate the two pending investigations. Pursuant to the order, the schedules for both investigations were revised to consolidate proceedings and set a unified evidentiary hearing on April 21-28, 2008, the filing of a single initial determination by Judge Luckern by July 11, 2008, and a target date for the consolidated investigations of November 12, 2008, by which date the USITC would issue its final determination (the “Target Date”).

     On December 4, 2007, Nokia moved for an order terminating or, alternatively, staying the USITC investigation as to Nokia, on the ground that Nokia and InterDigital must first arbitrate a dispute as to whether Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation. On January 8, 2008, Judge Luckern issued an order denying Nokia’s motion and holding that Nokia has waived its arbitration defense by instituting and participating in the investigation and other legal proceedings. On February 13, 2008, Nokia filed an action in the U.S. District Court for the Southern District of New York (the “Southern District Action”), seeking to preliminarily enjoin InterDigital from proceeding with the USITC investigation with respect to Nokia, in spite of Judge Luckern’s ruling denying Nokia’s motion to terminate the USITC investigation. Nokia raised in this preliminary injunction action the same arguments it raised in its motion to terminate the USITC investigation, namely that InterDigital allegedly must first arbitrate its alleged license dispute with Nokia and that Nokia has not waived arbitration of this defense. In the Southern District Action, Nokia also sought to compel InterDigital to arbitrate its alleged license dispute with Nokia and, in the alternative, sought a determination by the District Court that Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation. On March 7, 2008, InterDigital filed a motion to dismiss Nokia’s claim in the alternative that Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation.

     On February 8, 2008, Nokia filed a motion for summary determination in the USITC that InterDigital cannot show that a domestic industry exists in the United States as required to obtain relief. Samsung joined this motion. InterDigital opposed this motion. On February 14, 2008, InterDigital filed a motion for summary determination that InterDigital satisfies the domestic industry requirement based on its licensing activities. On February 26, 2008, InterDigital filed a motion for summary determination that it has separately satisfied the so-called “economic prong” for establishing that a domestic industry exists based on InterDigital’s chipset product that practices the asserted patents. Samsung and Nokia opposed these motions. On March 17, 2008, Samsung and Nokia filed a motion to strike any evidence concerning InterDigital’s product and to preclude InterDigital from introducing any such evidence in relation to domestic industry at the evidentiary hearing. On March 26, 2008, the Administrative Law Judge granted InterDigital’s motion for summary determination that it has satisfied the so-called “economic prong” for establishing that a domestic industry exists based on InterDigital’s chipset product that practices the asserted patents and denied Samsung’s motion to strike and preclude introduction of evidence concerning InterDigital’s domestic industry product.

     On March 17, 2008, Nokia and Samsung jointly moved for summary determination that U.S. Patent No. 6,693,579, which was asserted against both Samsung and Nokia, is invalid. InterDigital opposed this motion. On April 14, 2008, the Administrative Law Judge denied Nokia’s and Samsung’s joint motion for summary determination that the ‘579 patent is invalid.

     On March 20, 2008, the U.S. District Court for the Southern District of New York, ruling from the bench, decided that Nokia is likely to prevail on the issue of whether Nokia’s alleged entitlement to a license is arbitrable. The Court did not consider or rule on whether Nokia is entitled to such a license. As a result, the Court entered a preliminary injunction requiring InterDigital to participate in arbitration of the license issue and requiring InterDigital to cease participation in the USITC proceeding by April 11, 2008, but only with respect to Nokia. The Court further ordered Nokia to post a $500,000 bond by March 28, 2008, which Nokia did. InterDigital promptly filed a request for a stay of the preliminary injunction and for an expedited appeal with the U.S. Court of Appeals for the Federal Circuit, which transferred the appeal to the U.S. Court of Appeals for the Second Circuit. The preliminary injunction became effective on April 11, 2008, and, in accordance with the Court’s order, InterDigital filed a motion with the Administrative Law Judge to stay the USITC proceeding against Nokia pending InterDigital’s appeal of the District Court’s decision or, if that appeal were unsuccessful, pending the Nokia TDD Arbitration (described below). On April 14, 2008, the Administrative Law Judge ordered that the date for the commencement of the evidentiary hearing, originally

scheduled for April 21, 2008, be suspended until further notice from the Administrative Law Judge. The Administrative Law Judge did not at that point change the scheduled date of July 11, 2008 for his initial determination in the investigation or the scheduled Target Date of November 12, 2008 for a decision by the USITC. InterDigital’s motion for a stay of the preliminary injunction and for an expedited appeal was considered by a panel of the Second Circuit on April 15, 2008. On April 16, 2008, the Second Circuit denied the motion for stay but set an expedited briefing schedule for resolving InterDigital’s appeal on the merits of whether the District Court’s order granting the preliminary injunction should be reversed.

     On April 17, 2008, InterDigital filed a motion with the USITC to separate the consolidated investigations against Nokia and Samsung in order for the investigation to continue against Samsung pending the expedited appeal or, if the appeal is unsuccessful, pending the Nokia TDD Arbitration. Samsung and Nokia opposed InterDigital’s motion. On May 16, 2008, the Administrative Law Judge deconsolidated the investigations against Samsung and Nokia and set an evidentiary hearing date in the investigation against Samsung (337-TA-601) to begin on July 8, 2008.

     On May 20, 2008, the Administrative Law Judge denied without prejudice all pending motions in the consolidated investigation (337-TA-613).

     On June 17, 2008, a panel of the U.S. Court of Appeals for the Second Circuit heard oral argument on InterDigital’s appeal from the order of the U.S. District Court for the Southern District of New York preliminarily enjoining InterDigital from proceeding against Nokia in the consolidated investigation. On July 31, 2008, the Second Circuit reversed the preliminary injunction, finding that Nokia’s litigation conduct resulted in a waiver of any right to arbitrate its license dispute. InterDigital promptly notified the Administrative Law Judge in the Nokia investigation (337-TA-613) of the Second Circuit’s decision. On August 14, 2008, Nokia filed a petition for rehearing and petition for rehearing en banc of the Second Circuit’s decision, and on September 15, 2008, the Second Circuit denied Nokia’s petitions. The mandate from the Second Circuit issued to the Southern District of New York on September 22, 2008. Notwithstanding the Second Circuit’s decision, on October 17, 2008 Nokia filed a request for a status conference with the District Court to establish a procedural schedule for Nokia to pursue a permanent injunction requiring InterDigital to arbitrate Nokia’s alleged license defense, and arguing that the Second Circuit’s decision does not bar such an action. On October 23, 2008, InterDigital filed a response with the District Court asserting that the Second Circuit’s waiver finding was dispositive, and seeking the dismissal of Nokia’s complaint in its entirety. On March 5, 2009, the Court in the Southern District Action granted InterDigital’s request and dismissed all of Nokia’s claims in the Southern District Action, but delayed issuing a final judgment pending a request by InterDigital seeking to collect against the $500,000 preliminary injunction bond posted by Nokia. On April 3, 2009, InterDigital filed a motion to collect against the preliminary injunction bond, contending that InterDigital was damaged by at least $500,000 as a result of the wrongfully obtained preliminary injunction. On March 10, 2010, the District Court denied InterDigital’s motion to collect against the preliminary injunction bond. On April 9, 2010, InterDigital filed a notice of appeal with the District Court, indicating that InterDigital is appealing the denial of its motion to collect against the preliminary injunction bond to the U.S. Court of Appeals for the Second Circuit. InterDigital filed its opening brief in the appeal on July 28, 2010. Nokia’s brief is due to be filed by November 29, 2010, absent any extension. InterDigital may file a reply brief within 14 days after Nokia’s brief is filed, absent any extension. The Second Circuit has not yet entered a schedule for oral argument.

     On September 24, 2008, InterDigital filed a motion to lift the stay of the Nokia investigation (337-TA-613) based on the issuance of the Second Circuit’s mandate reversing the preliminary injunction granted to Nokia. The Administrative Law Judge granted InterDigital’s motion on September 25, 2008 and lifted the stay. On October 7, 2008, the Administrative Law Judge issued an order in the Nokia investigation setting the evidentiary hearing for May 26-29, 2009. On October 10, 2008, the Administrative Law Judge issued an order resetting the Target Date for the USITC’s Final Determination in the Nokia investigation to December 14, 2009, and requiring a final Initial Determination by the Administrative Law Judge to be entered no later than August 14, 2009.

     On January 21, 2009, Nokia filed a motion to schedule a claim construction hearing in the USITC proceeding in early February 2009, and on January 29, 2009, InterDigital filed an opposition to the motion for a claim construction hearing. On February 9, 2009, the Administrative Law Judge denied Nokia’s motion for a claim construction hearing.

     On February 13, 2009, InterDigital filed a renewed motion for summary determination that InterDigital has satisfied the domestic industry requirement based on its licensing activities, and on February 27, 2009, Nokia filed an opposition to the motion. On March 10, 2009, the Administrative Law Judge granted InterDigital’s motion, finding that InterDigital has established, through its licensing activities, that a domestic industry exists in the United States as required to obtain relief before the USITC. On April 9, 2009, the Commission issued a notice that it would not review the Administrative Law Judge’s Order granting summary determination of a licensing-based domestic industry, thereby adopting the Administrative Law Judge’s decision.

     The evidentiary hearing for the USITC investigation with respect to Nokia was held from May 26, 2009 through June 2, 2009.

     On August 14, 2009, the Administrative Law Judge issued an Initial Determination finding no violation of Section 337 of the Tariff Act of 1930. The Initial Determination found that InterDigital’s patents were valid and enforceable, but that Nokia did not infringe these patents. In

the event that a Section 337 violation were to be found by the Commission, the Administrative Law Judge recommended the issuance of a limited exclusion order barring entry into the United States of infringing Nokia 3G WCDMA handsets and components as well as the issuance of appropriate cease and desist orders.

     On August 31, 2009, InterDigital filed a petition for review of certain issues raised in the August 14, 2009 Initial Determination. On that same date, Nokia also filed a contingent petition for review of certain issues in the Initial Determination. Responses to both petitions were filed on September 8, 2009.

     On October 16, 2009, the Commission issued a notice that it had determined to review in part the Initial Determination, and that it affirmed the Administrative Law Judge’s determination of no violation and terminated the investigation. The Commission determined to review the claim construction of the patent claim terms “synchronize” and “access signal” and also determined to review the Administrative Law Judge’s validity determinations. On review, the Commission modified the Administrative Law Judge’s claim construction of “access signal” and took no position with regard to the claim term “synchronize” or the validity determinations. The Commission determined not to review the remaining issues decided in the Initial Determination.

     On November 30, 2009, InterDigital filed with the United States Court of Appeals for the Federal Circuit a petition for review of certain rulings by the Commission. In the appeal, neither the construction of the term “synchronize” nor the issue of validity can be raised because the Commission took no position on these issues in its determination. On December 17, 2009, Nokia filed a motion to intervene in the appeal, which was granted by the Court on January 4, 2010. InterDigital’s opening brief was filed on April 12, 2010. In its appeal, InterDigital seeks reversal of the Commission’s claim constructions and non-infringement findings with respect to certain claim terms in U.S. Patent Nos. 7,190,966 and 7,286,847, vacatur of the Commission’s determination of no Section 337 violation, and a remand for further proceedings before the Commission. InterDigital is not appealing the Commission’s determination of non-infringement with respect to U.S. Patent Nos. 6,973,579 and 7,117,004. Nokia and the Commission filed their briefs on July 13, 2010. In their briefs, Nokia and the Commission argue that the Commission correctly construed the claim terms asserted by InterDigital in its appeal and that the Commission properly determined that Nokia did not infringe the patents on appeal. Nokia also argues that the Commission’s finding of noninfringement should be affirmed based on an additional claim term. Nokia further argues that the Commission erred in finding that InterDigital could satisfy the domestic industry requirement based solely on its patent licensing activities and without proving that an article in the United States practices the claimed inventions, and that the Commission’s finding of no Section 337 violation should be affirmed on that additional basis. InterDigital filed its reply brief on August 30, 2010. The Court has scheduled oral argument for December 9, 2010.

     InterDigital has no obligation as a result of the above matter and we have not recorded a related liability in our financial statements.

     Other

     We are party to certain other disputes and legal actions in the ordinary course of business. We do not believe that these matters, even if adversely adjudicated or settled, would have a material adverse effect on our financial condition, results of operations or cash flows.

7. REPURCHASE OF COMMON STOCK:

     In March 2009, our Board of Directors authorized a $100.0 million share repurchase program (the “2009 Repurchase Program”). The Company can repurchase shares under the program through open market purchases, pre-arranged trading plans, or privately negotiated purchases. During 2009, we repurchased approximately 1.0 million shares for $25.0 million under the 2009 Repurchase Program, of which approximately 0.4 million shares were repurchased for $10.3 million during third quarter 2009. We did not make any share repurchases during first nine months 2010 or from October 1, 2010 through October 29, 2010.

Total comprehensive income		$	119,312			$	48,554

9. CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES:

Concentration of Credit Risk and Fair Value of Financial Instruments

     Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. We place our cash equivalents and short-term investments only in highly rated financial instruments and in United States government instruments.

     Our accounts receivable are derived principally from patent license and technology solutions agreements. At September 30, 2010, four customers comprised 84% of our net accounts receivable balance. At December 31, 2009, one customer represented 94% of our net accounts receivable balance. We perform ongoing credit evaluations of our customers, who generally include large, multinational, wireless telecommunications equipment manufacturers. We believe that the carrying value of our financial instruments approximate their fair values.

Fair Value Measurements

     Effective January 1, 2008, we adopted the provisions of the FASB fair value measurement guidance that relate to our financial assets and financial liabilities. We adopted the guidance related to non-financial assets and liabilities as of January 1, 2009. We use various valuation techniques and assumptions when measuring fair value of our assets and liabilities. We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. This guidance established a hierarchy that prioritizes fair value measurements based on the types of input used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below:

Level 1 Inputs — Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets.

Level 2 Inputs — Level 2 includes financial instruments for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets with insufficient volume or infrequent transactions (less active markets) or model-driven valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data, including market interest rate curves, referenced credit spreads and pre-payment rates.

Level 3 Inputs — Level 3 includes financial instruments for which fair value is derived from valuation techniques including pricing models and discounted cash flow models in which one or more significant inputs are unobservable, including the Company’s own assumptions. The pricing models incorporate transaction details such as contractual terms, maturity and, in certain instances, timing and amount of future cash flows, as well as assumptions related to liquidity and credit valuation adjustments of marketplace participants.

     Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial assets and financial liabilities and their placement within the fair value hierarchy. We use quoted market prices for similar assets to estimate the fair value of our Level 2 investments. Our financial assets that are accounted for at fair value on a recurring basis are presented in the tables below (in thousands):

		Fair Value as of September 30, 2010
		Level 1				Level 2				Level 3				Total
Assets:

10. SUBSEQUENT EVENTS:

Technology Solutions Agreements

     In first quarter 2010, we entered into a technology transfer and license agreement with Beceem Communications Inc. (“Beceem”). Beceem was granted non-exclusive, worldwide licenses to certain 2G and 3G signal processing technologies to develop, implement, and use in multimode 4G chips. In fourth quarter 2010, Broadcom Corporation (“Broadcom”) signed a definitive agreement to acquire Beceem. The transaction is expected to close in either fourth quarter 2010 or first quarter 2011. Pending closing of the transaction, InterDigital’s technology solutions agreement with Beceem will continue in accordance with its terms, including all payment obligations. However, we have agreed to suspend ongoing development work and engineering services until a date certain. Upon closing of the announced Broadcom/Beceem transaction, the agreement will terminate under mutually agreeable financial terms and Beceem/Broadcom will have no license to sell products incorporating our technology or to otherwise use our technology and Beceem will fully remove our technology from all of its products. Should the Broadcom/Beceem transaction fail to close by the date certain, we will resume development work under the terms of our existing agreement.

     As discussed in “Other Information” in Part II, Item 5 of the Form 10-Q, the compensation committee of InterDigital’s board of directors approved certain changes to the company’s compensation programs on October 26, 2010. The company intends that such changes to its compensation structure will decrease the proportion of compensation that is time-based relative to the proportion that is performance-based and, as a result, expects that the changes will result in a slight decrease in the total compensation paid to the named executive officers as well as to the company’s employees as a whole. Whether the net effect of the changes is an increase or a decrease in total compensation, however, will ultimately depend on the company’s level of achievement of the applicable performance goals.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

OVERVIEW

     The following discussion should be read in conjunction with the unaudited, condensed consolidated financial statements and notes thereto contained in Part I, Item 1 of this Quarterly Report on Form 10-Q, in addition to our 2009 Form 10-K, other reports filed with the SEC and the Statement Pursuant to the Private Securities Litigation Reform Act of 1995 — Forward-Looking Statements below. Please refer to the Glossary of Terms in our 2009 Form 10-K for a list and detailed descriptions of the various technical, industry and other defined terms that are used in this Quarterly Report on Form 10-Q.

Patent Licensing

     Patent licensing royalties of $86.1 million in third quarter 2010 increased $1.0 million or 1% over second quarter 2010. This sequential increase was driven by a $5.2 million increase in fixed fee and per-unit royalties from existing customers, partly offset by a $4.2 million decrease in past sales. The increase in fixed fee and per-unit royalties resulted from strong sales from our customers with concentrations in smart phones, while past sales decreased due to the second quarter 2010 renewal of a patent license agreement that contributed to per-unit revenue in both periods and past sales in second quarter 2010 only.

Technology Solutions

     Technology solutions revenue in third quarter 2010 of $5.8 million decreased $0.3 million or 5% from second quarter 2010. The decrease was driven by a $0.8 million decrease in technology solutions royalties, partly offset by a $0.5 million increase in revenue from technology solutions customers added in 2010.

Intellectual Property Enforcement

     Please see Note 6, “Litigation and Legal Proceedings,” in the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for a full discussion of the following matter and other matters:

     On October 16, 2009, it was announced that in the U.S. International Trade Commission (“USITC”) investigation initiated by us against Nokia, the USITC issued a notice that it reviewed in part the Initial Determination (“ID”) by the Chief Administrative Law Judge (“ALJ”) and found no violation of Section 337 and has terminated the investigation. In the ID, the ALJ found InterDigital’s patents valid and enforceable, but also determined that the patents were not infringed by Nokia’s 3G products. The USITC action originated in August 2007, when we filed a complaint with the USITC alleging that Nokia engaged in unfair trade practices by selling for importation into the United States, importing, and selling after importation, certain 3G handsets and components that infringe four of our U.S. patents.

     On November 30, 2009, we filed an appeal of the USITC’s decision to the United States Court of Appeals for the Federal Circuit. On December 17, 2009, Nokia filed a motion to intervene in the appeal, which was granted by the Court on January 4, 2010. InterDigital’s opening brief was filed on April 12, 2010. In its appeal, InterDigital seeks reversal of the USITC’s claim constructions and non-infringement findings with respect to certain claim terms in U.S. Patent Nos. 7,190,966 and 7,286,847, vacatur of the USITC’s determination of no Section 337 violation, and a remand for further proceedings before the USITC. InterDigital is not appealing the USITC’s determination of non-infringement with respect to U.S. Patent Nos. 6,973,579 and 7,117,004. Nokia and the USITC filed their briefs on July 13, 2010. In their briefs, Nokia and the USITC argue that the USITC correctly construed the claim terms asserted by InterDigital in its appeal and that the USITC properly determined that Nokia did not infringe the patents on appeal. Nokia also argues that the USITC’s finding of non-infringement should be affirmed based on an additional claim term. Nokia further argues that the USITC erred in finding that InterDigital could satisfy the domestic industry requirement based solely on its patent licensing activities and without proving that an article in the United States practices the claimed inventions, and that the USITC’s finding of no Section 337 violation should be affirmed on that additional basis. InterDigital filed its reply brief on August 30, 2010. The Court has scheduled oral argument for December 9, 2010.

Comparability of Financial Results

     When comparing third quarter 2010 financial results against other periods, the following items should be taken into consideration:

•

Our third quarter 2010 revenue included $0.7 million of past sales, primarily related to the signing of a new patent license agreement.

•

Our third quarter 2010 operating expenses included a charge of $0.6 million to increase a bad debts reserve related to one of our technology solutions customers.

•

Our third quarter 2009 revenue included $0.5 million of past sales, primarily related to the signing of a new patent license agreement.

•

Our third quarter 2009 operating expenses were reduced by $4.0 million based on revised expectations for the anticipated payout associated with a long-term performance-based incentive program; this adjustment reduced third quarter 2009 development expense, selling, general and administrative expense, and patent administration and licensing costs by $2.4 million, $1.1 million, and $0.5 million, respectively.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     Our significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements included in our 2009 Form 10-K. A discussion of our critical accounting policies, and the estimates related to them, are included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2009 Form 10-K. There have been no material changes in our existing critical accounting policies from the disclosures included in our 2009 Form 10-K. Refer to Note 1, “Basis of Presentation,” in the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for updates related to new accounting pronouncements.

FINANCIAL POSITION, LIQUIDITY AND CAPITAL REQUIREMENTS

     Our primary sources of liquidity are cash, cash equivalents and short-term investments, as well as cash generated from operations. We have the ability to obtain additional liquidity through debt and equity financings, but have not had a significant debt or equity financing in over 10 years and do not anticipate a need for such financings in the next twelve months. Based on our past performance and current expectations, we believe our available sources of funds, including cash, cash equivalents and short-term investments and cash generated from our operations, will be sufficient to finance our operations, capital requirements, our existing stock repurchase program and any stock repurchase or dividend program that we may initiate in the next twelve months.

Cash, cash equivalents and short-term investments

     At September 30, 2010 and December 31, 2009, we had the following amounts of cash, cash equivalents and short-term investments (in thousands):

										Increase /
		September 30, 2010				December 31, 2009				(Decrease)
Cash and cash equivalents		$	313,620			$	210,863			$	102,757
Short-term investments			249,960				198,943				51,017
Total Cash and cash equivalents and short-term investments		$	563,580			$	409,806			$	153,774

     Our cash, cash equivalents and short-term investments increased $153.8 million in first nine months 2010. The increase was primarily due to our receipts of the third and fourth of four $100.0 million installments from Samsung Electronics Co., Ltd. (“Samsung”) under our patent license agreement signed in January 2009. After using these and other receipts to fund our operations and working capital requirements in first nine months 2010, we invested the excess in short-term investments.

Cash flows from operations

     We generated the following cash flows from our operating activities in first nine months 2010 and 2009 (in thousands):

		For the Nine Months Ended September 30,
										Increase /
		2010				2009				(Decrease)
Cash flows from operating activities		$	163,144			$	332,502			$	(169,358	)

     The positive operating cash flow in first nine months 2010 arose principally from receipts of approximately $344.6 million related to patent license and technology solutions agreements. These receipts included the third and fourth of four $100.0 million installments from Samsung under our January 2009 license agreement. We also received $6.7 million of fixed fee payments and $125.1 million of per-unit royalty payments, including past sales and prepayments, from other existing and new customers. Cash receipts from our technology solutions agreements totaled $12.8 million, primarily related to royalties and other license fees associated with our SlimChip modem core. These receipts were partially offset by cash operating expenses (operating expenses less depreciation of fixed assets, amortization of intangible assets, and non-cash compensation) of $96.6 million, cash payments for foreign source withholding taxes of $35.2 million primarily related to the Samsung installments, and estimated federal tax payments of $53.0 million.

          The positive operating cash flow in first nine months 2009 arose principally from receipts of approximately $492.0 million related to patent license and technology solutions agreements. These receipts included the first two of four installments of $100.0 million from Samsung under our January 2009 license agreement. We also received prepayments of $182.4 million from two existing customers, per-unit royalty payments of $61.6 million from other existing customers, other fixed fee payments of $37.1 million, and cash receipts from our technology solutions agreements totaling $10.9 million, primarily related to royalties associated with our SlimChip modem core. These receipts were partially offset by cash operating expenses (operating expenses less depreciation of fixed assets, amortization of intangible assets, non-cash repositioning charges and non-cash compensation) of $92.0 million, cash payments for foreign source withholding taxes of $40.7 million related to cash receipts under the Samsung agreement and our patent license agreement with Pantech Co., Ltd and Pantech & Curitel

Communications, Inc. (“Pantech”) signed in September 2009, an estimated federal tax payment of $4.0 million, and changes in working capital during first nine months 2009.

Working capital

     We believe that working capital, adjusted to exclude cash, cash equivalents, short-term investments, current maturities of debt, and current deferred revenue provides additional information about non-cash assets and liabilities that might affect our near-term liquidity. Our adjusted working capital, a non-GAAP financial measure, reconciles to working capital, the most directly comparable GAAP financial measure, at September 30, 2010 and December 31, 2009 (in thousands) as follows:

		September 30, 2010				December 31, 2009				Increase / (Decrease)
Current assets		$	642,002			$	702,322			$	(60,320	)
Current liabilities			(224,416	)			(252,560	)			28,144
Working capital			417,586				449,762				(32,176	)
(Subtract) Add
Cash and cash equivalents			(313,620	)			(210,863	)			(102,757	)
Short-term investments			(249,960	)			(198,943	)			(51,017	)
Current portion of long-term debt			286				584				(298	)
Current deferred revenue			157,997				193,409				(35,412	)
Adjusted working capital		$	12,289			$	233,949			$	(221,660	)

     The $221.7 million decrease in adjusted working capital is primarily attributable to the decrease in accounts receivable associated with the third and fourth of four $100.0 million installments from Samsung, which we received during first nine months 2010. Additionally, our satisfaction of estimated federal tax obligations reduced our short-term deferred tax assets and contributed to the decrease in adjusted working capital. An $11.0 million increase in accrued compensation and accounts payable also reduced our adjusted working capital during first nine months 2010. The increase in accrued compensation is primarily attributable to our long-term performance-based cash incentive program, a payout under which is scheduled to be paid within twelve months from the current balance sheet date. The increase in accounts payable is primarily associated with sublicense obligations incurred in conjunction with our new technology solutions agreements signed in first nine months 2010.

Cash Used in or Provided by Investing and Financing Activities

     We used net cash in investing activities of $72.8 million and $147.8 million in first nine months 2010 and 2009, respectively. We purchased $51.1 million and $122.3 million of short-term marketable securities, net of sales, in first nine months 2010 and 2009, respectively. This decrease in net purchases was driven by higher cash needs to make estimated tax payments during 2010. Purchases of property and equipment and technology licenses decreased to $1.7 million in first nine months 2010 from $3.5 million in first nine months 2009 due to the lower levels of development tools and engineering equipment needed in first nine months 2010 as a result of our cessation of further SlimChip product development. Investment costs associated with patents decreased to $20.0 million in the first nine months 2010 from $21.9 million for first nine months 2009.

     Net cash provided (used) by financing activities increased by $31.5 million primarily due to our first nine months 2009 share repurchase activity, which did not recur in first nine months 2010, and higher levels of proceeds from stock option exercises.

Other

     Our combined short-term and long-term deferred revenue balance at September 30, 2010 was approximately $531.1 million, a decrease of $137.1 million from December 31, 2009. We have no material obligations associated with such deferred revenue. In first nine months 2010, deferred revenue decreased $209.1 million due to the deferred revenue recognition of $146.3 million related to the amortization of fixed fee royalty payments and $62.8 million related to per-unit exhaustion of prepaid royalties (based upon royalty reports provided by our customers) and technology solutions. These decreases in deferred revenue were partially offset by gross increases in deferred revenue of $72.0 million, primarily related to patent license agreements and new technology solutions agreements signed in first nine months 2010.

     Based on current license agreements, we expect the amortization of fixed fee royalty payments to reduce the September 30, 2010 deferred revenue balance of $531.1 million by $158.0 million over the next twelve months. Additional reductions to deferred revenue will be dependent upon the level of per-unit royalties our customers report against prepaid balances and work performed in conjunction with our technology solutions agreements.

     At September 30, 2010 and December 31, 2009, we had approximately 1.5 million and 2.1 million options outstanding, respectively, that had exercise prices less than the fair market value of our stock at each balance sheet date. These options would generate $20.3 million and $30.4 million of cash proceeds to the Company if they are fully exercised.

RESULTS OF OPERATIONS

Third Quarter 2010 Compared to Third Quarter 2009

Revenues

     The following table compares third quarter 2010 revenues to revenues in the comparable prior year period (in millions):

		For the Three Months
		Ended September 30,
		2010				2009				Increase/ (Decrease)
Fixed fee amortized royalty revenue		$	49.6			$	44.8			$	4.8				11	%
Per-unit royalty revenue			35.8				27.7				8.1				29	%
Past sales			0.7				0.5				0.2				40	%
Total patent licensing royalties			86.1				73.0				13.1				18	%
Technology solutions revenue			5.8				2.5				3.3				132	%
Total revenue		$	91.9			$	75.5			$	16.4				22	%

     The $16.4 million increase in total revenue in third quarter 2010 was primarily attributable to a $13.1 million increase in patent licensing royalties. Of this increase in patent licensing royalties, $8.1 million was attributable to an increase in per-unit royalty revenue primarily resulting from (i) the second quarter 2010 renewal of a patent license agreement and (ii) an aggregate increase in royalties from our remaining existing per-unit customers. The remaining $5.0 million increase in patent licensing royalties was driven by increases in fixed fee amortized royalty revenue and past sales revenue.

     The increase in fixed fee amortized royalty revenue was driven by a full quarter of revenue from our September 2009 patent license agreement with Pantech, compared to a partial quarter of revenue in third quarter 2009, and our second quarter 2010 amendment to our patent license agreement with an existing customer.

     The increase in past sales revenue was attributable to the signing of a patent license agreement with a new customer in third quarter 2010, as well as the resolution of a routine audit of an existing customer.

     The increase in technology solutions revenue was attributable to agreements signed during first nine months 2010, which collectively contributed $3.7 million of revenue in third quarter 2010.

     In third quarter 2010 and third quarter 2009, 55% and 64% of our total revenues for the respective periods were attributable to companies that individually accounted for 10% or more of these amounts. During third quarter 2010 and third quarter 2009, the following customers accounted for 10% or more of our total revenues:

		For the Three Months
		Ended September 30,
		2010				2009
Samsung Electronics Company, Ltd.			28	%			34	%
LG Electronics			16	%			19	%
Sharp Corporation			11	%			11	%

Operating Expenses

The following table summarizes the change in operating expenses by category (in millions):

		For the Three Months
		Ended September 30,
		2010				2009				Increase/ (Decrease)
Selling, general and administrative		$	7.2			$	4.9			$	2.3				47	%
Patent administration and licensing			12.8				13.3				(0.5	)			(4	)%
Development			17.5				10.7				6.8				64	%
Total operating expenses		$	37.5			$	28.9			$	8.6				30	%

   Operating expenses increased 30% to $37.5 million in third quarter 2010 from $28.9 million in third quarter 2009. The $8.6 million increase was primarily due to net changes in the following items (in millions):

		Increase/
		(Decrease)
Long-term compensation		$	3.9
Sublicense fees			2.0
Consulting services			1.7
Depreciation and amortization			0.7
Personnel-related costs			0.7
Other			0.6
Reserve for uncollectible accounts			0.6
Patent maintenance and patent evaluation			0.4
Intellectual property enforcement			(2.0	)
Total increase in operating expenses		$	8.6

     The increase in long-term compensation primarily resulted from a third quarter 2009 reduction of $4.0 million to the accrual for the incentive period January 1, 2008 through December 31, 2010. This reduction related to lowering our expected payout from 100% to 50% in third quarter 2009. We have subsequently raised the expected payout to 70% in connection with revenue-producing agreements signed in first nine months 2010. Our technology solutions agreements signed in first nine months 2010 resulted in an increase in sublicense fees and consulting services. Additionally, consulting services also increased in connection with research and development projects initiated within the last twelve months. The increase in depreciation and amortization is related to the increase over time in our capitalized patent costs. Personnel-related costs increased $0.7 million due to salary increases. The increase in patent maintenance and patent evaluation costs were related to increased activity in the management of our patent portfolio and due diligence associated with patent acquisition opportunities. In third quarter 2010, we increased our reserve for uncollectible accounts by $1.8 million. We recorded a charge of $0.6 million and a reduction of deferred revenue of $1.2 million in connection with this reserve. These increases were partially offset by a decrease in intellectual property enforcement primarily due to a decrease in activity associated with our Nokia USITC case.

Selling, General and Administrative Expense: The increase in selling, general and administrative expense was primarily attributable to the above-noted increase in long-term compensation and the reserve for uncollectible accounts.

Patent Administration and Licensing Expense: The decrease in patent administration and licensing expense primarily resulted from the above-noted decrease in intellectual property enforcement. This decrease was partially offset by increases in long-term compensation, patent maintenance and patent evaluation costs, and patent amortization.

Development Expense: The increase in development expense was primarily attributable to the above-noted increases in long-term compensation, consulting services, and sublicense fees.

First Nine Months 2010 Compared to First Nine Months 2009

Revenues

     The following table compares first nine months 2010 revenues to revenues in the prior year comparable period (in millions):

		For the Nine Months
		Ended September 30,
		2010				2009				Increase/ (Decrease)
Fixed fee amortized royalty revenue		$	146.3			$	133.7			$	12.6				9	%
Per-unit royalty revenue			97.4				78.5				18.9				24	%
Past sales			41.3				2.8				38.5				1375	%
Total patent licensing royalties			285.0				215.0				70.0				33	%
Technology solutions revenue			14.3				6.0				8.3				138	%
Total revenue		$	299.3			$	221.0			$	78.3				35	%

   The $78.3 million increase in total revenue in first nine months 2010 was primarily attributable to a $70.0 million increase in patent licensing royalties. Of this increase in patent licensing royalties, $38.5 million was attributable to past sales primarily resulting from (i) the first quarter 2010 patent license agreement signed with CMHC, (ii) the first quarter 2010 resolution of a routine audit with an existing customer, and (iii) the renewal of a patent license agreement in second quarter 2010. The remaining $31.5 million increase was driven by increases in per-unit royalty revenue ($18.9 million) and fixed fee amortized royalty revenue ($12.6 million).

     Per-unit royalty revenues increased $18.9 million due to the first quarter 2010 entry into the patent license agreement with CMHC, the second quarter 2010 renewal of a patent license agreement, a full nine months of revenue from license agreements signed in 2009, and an aggregate increase in royalties from our remaining existing per-unit customers.

     The increase in fixed fee amortized royalty revenue was driven by a full nine months of revenue from the patent license agreement with Samsung signed during first quarter 2009 and the September 2009 patent license agreement with Pantech. These increases were partially offset by the expiration of a fixed fee license agreement in second half 2009, which, as noted above, was renewed in second quarter 2010 as a per-unit agreement.

     The increase in technology solutions revenue was attributable to technology solutions agreements signed during first nine months 2010, which collectively contributed revenue of $6.8 million, as well as increased royalties earned on our SlimChip modem core platform relating to our customers’ product sales.

     During first nine months 2010 and first nine months 2009, 51% and 63% of our total revenues for the respective periods were attributable to companies that individually accounted for 10% or more of these amounts. During first nine months 2010 and first nine months 2009, the following customers accounted for 10% or more of our total revenues:

		For the Nine Months
		Ended September 30,
		2010				2009
Samsung Electronics Company, Ltd.			26	%			33	%
LG Electronics			14	%			20	%
Casio Hitachi Mobile Communications Co., Ltd.			11	%			<10	%
Sharp Corporation			<10	%			10	%

Operating Expenses

     The following table summarizes the change in operating expenses by category (in millions):

		For the Nine Months
		Ended September 30,
		2010				2009				Increase/ (Decrease)
Selling, general and administrative		$	21.8			$	19.2			$	2.6				14	%
Patent administration and licensing			45.3				41.0				4.3				11	%
Development			50.0				50.8				(0.8	)			(2	)%
Repositioning			—				37.0				(37.0	)			(100	)%
Total operating expenses		$	117.1			$	148.0			$	(30.9	)			(21	)%

     Operating expenses decreased 21% to $117.1 million in first nine months 2010 from $148.0 million in first nine months 2009. Not including a $37.0 million repositioning charge in first nine months 2009, operating expenses would have increased 6%. The $30.9 million decrease was primarily due to the following net changes in expenses (in millions):

		Increase/
		(Decrease)
Long-term compensation		$	5.1
Sublicense fees			2.9
Patent amortization			2.2
Patent maintenance and patent evaluation			1.9
Reserve for uncollectible accounts			1.1
Other			0.2
Personnel-related costs			(0.6	)
Consulting services			(0.9	)
Intellectual property enforcement			(1.2	)
Engineering software and equipment maintenance			(1.2	)
Depreciation and amortization			(3.4	)
Total increase in operating expenses not including repositioning charges			6.1
Repositioning charge			(37.0	)
Total decrease in operating expenses		$	(30.9	)

     In connection with our first quarter 2009 decision to cease further development of our SlimChip modem technology, we wrote off approximately 73% of the net carrying value of our fixed assets and development licenses and decreased our headcount by approximately 25%. As a result of these actions, consulting services, personnel-related costs, depreciation and amortization, and engineering software and equipment maintenance decreased approximately $6.1 million. The increase in long-term compensation primarily resulted from a third quarter 2009 reduction of $4.0 million to the accrual for the incentive period January 1, 2008 through December 31, 2010. This reduction related to lowering our expected payout from 100% to 50% in third quarter 2009. During first nine months 2010, we incurred a $1.8 million charge to increase the accrual rate to 70% in connection with revenue-producing agreements signed in first nine months 2010. The increase in sublicense fees related to our technology solutions agreements signed in first nine months 2010. Patent amortization increased due to the increase over time in our capitalized patent costs. The increase in patent maintenance and patent evaluation costs were related to increased activity in management of our patent portfolio and due diligence associated with patent acquisition opportunities. In first nine months 2010, we recorded a net increase of $1.3 million to our reserve for uncollectible accounts. We recorded a net charge of $0.1 million and a reduction of deferred revenue of $1.2 million in connection with this increase. In first nine months 2009, we recorded a benefit of $1.0 million in connection with a reduction of our reserve for uncollectible accounts. The decrease in intellectual property enforcement was primarily due to a decrease in activity associated with our Nokia USITC case.

Selling, General and Administrative Expense: The increase in selling, general and administrative expense was primarily attributable to the above-noted increase in long-term compensation and the reserve for uncollectible accounts.

Patent Administration and Licensing Expense: The increase in patent administration and licensing expense was primarily attributable to the above-noted increases in long-term compensation, patent amortization, and patent maintenance and patent evaluation. These increases were partially offset by the above-noted reduction in intellectual property enforcement.

Development Expense: The decrease in development expense was primarily attributable to the reduction of consulting services, depreciation and amortization, personnel-related costs, and engineering software and equipment maintenance resulting from the repositioning announced on March 30, 2009. These decreases were offset, in part, by the above-noted increase in long-term compensation and sublicense fees.

Repositioning Expense: On March 30, 2009, we announced a repositioning plan under which we (i) expanded our technology development and licensing business and (ii) ceased further product development of our SlimChip HSPA technology. In connection with the repositioning plan, we incurred certain costs associated with exit or disposal activities. The repositioning resulted in a reduction in force of approximately 100 employees across our three locations. We incurred a repositioning charge of $37.1 million in first quarter 2009 and additional costs of $1.5 million during the balance of 2009. We did not incur any additional charges under this plan in first nine months 2010, nor do we expect to incur any related charges in the future.

Expected Trends

     We will provide our expectations for our fourth quarter 2010 revenue after we receive and review the applicable patent licensing and product sales royalty reports.

Item 5. OTHER INFORMATION

     On October 26, 2010, the compensation committee of InterDigital’s board of directors approved certain changes to the company’s compensation programs, including the compensation plans and arrangements of InterDigital’s chief executive officer, chief financial officer and other named executive officers as identified in the company’s 2010 definitive proxy statement filed with the Securities and Exchange Commission on April 30, 2010 (the “2010 proxy statement”). The changes relate to the company’s (i) long-term compensation program (“LTCP”), (ii) annual bonus plan, or short-term incentive plan (“STIP”), (iii) supplemental payment program and (iv) profit-sharing program, each of which has been previously described by InterDigital in the Compensation Discussion and Analysis section of the 2010 proxy statement.

Long-Term Compensation Program

     The compensation committee approved certain amendments to the LTCP to provide the committee with flexibility to respond more rapidly to changing market dynamics, accounting rules and other organizational factors. Prior to being amended, the LTCP, which consists of overlapping cycles that are generally three years in length, was designed to alternate between equity and cash cycles, with equity cycles including both time-based and performance-based components and cash cycles consisting of a performance-based cash incentive. Under the equity cycles, executives, including the named executive officers, received 50% of their equity awards in the form of performance-based restricted stock units (“RSUs”) and 50% in the form of time-based RSUs that vested in full at the end of the three-year cycle period.

     Under the terms of the amended LTCP, effective for the cycle that began on January 1, 2010 and cycles thereafter, all executives, including the named executive officers, will receive 25% of their LTCP participation in the form of time-based RSUs that vest in full at the end of the three-year cycle period and the remaining 75% in the form of performance-based awards granted under the long-term incentive plan (“LTIP”) component of the LTCP. The LTIP performance-based awards may be paid out in the form of cash or equity or any combination thereof. The form of the LTIP award will be determined by the compensation committee in its sole discretion at the beginning or the end of the three-year cycle.

     The level of participation in the LCTP for each named executive officer, which is established as a target percentage of their annual base salary, remains unchanged. Payouts of performance-based awards will continue to be determined by the compensation committee in its sole discretion based on the company’s achievement of one of more performance goals during the cycle period, as established and approved by the compensation committee. Payouts pursuant to the LTIP may exceed or be less than target, depending on the level of the company’s achievement of the performance goal(s). No payout may be made if the company fails to achieve the minimum level of performance for the applicable cycle, and the payout for any particular cycle is capped at 200% of target.

     This description is qualified in its entirety by reference to the amended LTCP, a copy of which is filed as Exhibit 10.1 to this Quarterly Report on Form 10-Q and is incorporated herein by reference.

Short-Term Incentive Plan, Supplemental Payment Program and Profit-Sharing Program

     The compensation committee also made certain changes and decisions with respect to the STIP and the company’s supplemental payment and profit-sharing programs in order to further enhance the company’s performance-based compensation programs and to simplify the company’s overall compensation structure by reducing the number of compensation elements used.

     The STIP, a key element of performance-based compensation, was amended to increase the targeted award amount for each participant, which is expressed as a percentage of annual base salary, by five percentage points. Accordingly, effective with the 2011 plan year, the targets under the STIP for each of the named executive officers are as follows: 80% for William Merritt, 55% for Scott McQuilkin and Lawrence Shay and 45% for Mark Lemmo and James Nolan. The amended STIP is filed as Exhibit 10.2 to this Quarterly Report on Form 10-Q and is incorporated herein by reference.

     The company’s supplemental payment program, pursuant to which each executive, including the named executive officers, received annual grants of 1,000 shares of the company’s common stock, subject to a one-year restriction on transferability, was terminated by the compensation committee.

     Finally, the compensation committee determined that it would not elect to make a profit-sharing contribution to each employee in 2011, or for the foreseeable future, pursuant to a discretionary provision in the company’s 401(k) savings plan. In prior years, the compensation committee had approved a profit-sharing contribution to each employee, including each named executive officer, ranging from 1.0% to 1.5% of the employee’s annual salary. This decision is not intended to be reflective of the company’s recent financial performance but rather is consistent with the compensation committee’s intent to simplify the company’s overall compensation structure.
