In addition, when you vote via the Internet, your vote is recorded immediately and there is no risk that postal delays will cause your vote to arrive late and therefore not be counted. If you do not vote via the Internet, please vote by telephone or by completing, signing, dating and returning the accompanying proxy card in the enclosed return envelope. Submitting your proxy by Internet, telephone or mail will not affect your right to vote in person if you decide to attend the annual meeting.

This proxy statement contains information related to our annual meeting of shareholders to be held on Thursday, June 5, 2008, beginning at 11:00 a.m. Eastern Daylight Time, at the Radisson Hotel Valley Forge, 1160 First Avenue, King of Prussia, Pennsylvania 19406, and at any postponements or adjournments of the meeting. Your proxy for the meeting is being solicited by our board of directors. This proxy statement and our annual report are being mailed to shareholders beginning on or about April 29, 2008.
 
ABOUT THE MEETING AND VOTING
 
What is the purpose of the annual meeting?
 
At our annual meeting, shareholders will act upon the matters outlined in the notice of meeting provided with this proxy statement, including the election of directors, ratification of the appointment of our independent registered public accounting firm and such other business as may properly come before the meeting. In addition, management will report on the performance of our company and respond to questions from shareholders.
 
Who may attend the meeting?
 
Subject to space availability, all shareholders as of April 8, 2008, the record date, or their duly appointed proxies, may attend the meeting. Registration will begin at 9:30 a.m. and seating will begin at 10:30 a.m. If you plan to attend the meeting, please note that you will need to bring your admission ticket and valid picture identification, such as a driver’s license or passport. Cameras, recording devices and other electronic devices will not be permitted at the meeting and all cellular phones must be silenced during the meeting. We realize that many cellular phones have built-in digital cameras, and while these phones may be brought into the meeting, the camera function may not be used at any time.
 
Please also note that if you hold your shares in “street name” (that is, through a broker or other nominee), you will need to bring a copy of a brokerage statement reflecting your stock ownership as of the record date.
 
Who is entitled to vote at the meeting?
 
Only shareholders of record at the close of business on April 8, 2008, the record date, are entitled to receive notice of and to participate in the annual meeting. If you were a shareholder of record on that date, you will be entitled to vote all of the shares that you held on that date at the meeting, or any postponements or adjournments of the meeting. There were 45,857,629 shares of our common stock outstanding on the record date.
 
What are the voting rights of the holders of the company’s common stock?
 
Each share of our common stock outstanding on the record date will be entitled to one vote on each matter considered at the meeting.
 
What is a quorum?
 
A quorum is the minimum number of our shares of common stock that must be represented at a duly called meeting in person or by proxy in order to legally conduct business at the meeting. For the annual meeting, the presence, in person or by proxy, of the holders of a majority of the shares entitled to vote will be


Table of Contents

considered a quorum. If you are a registered shareholder, you must deliver your proxy by Internet, telephone or mail or attend the annual meeting in person and vote in order to be counted in the determination of a quorum. If you are a “street name” shareholder, your broker or other nominee will vote your shares pursuant to your proxy directions and such shares will count in the determination of a quorum. If you do not provide any directions to your broker or other nominee, your shares will still count for purposes of attaining a quorum and your broker or other nominee may vote your shares in its discretion on proposals 1 and 2.
 
How do I vote?
 
If you are a registered shareholder, you may submit your proxy by Internet, telephone or mail by following the instructions included with your proxy card. The deadline for submitting your proxy by Internet or telephone is 11:59 p.m., Eastern Daylight Time, on June 4, 2008. The designated proxy will vote according to your instructions. You may also attend the meeting and deliver a proxy card to be voted in the same manner or you may personally vote by ballot.
 
If you are a “street name” shareholder, your properly signed and returned voting instruction card will be tabulated and voted by your broker or other nominee. Please check your voting instruction card or contact your broker or other nominee to determine whether you will be able to deliver your voting instructions by Internet or telephone. If you are a “street name” shareholder and you want to vote at the meeting, you will need to obtain a signed proxy from the broker or nominee that holds your shares, because the broker or nominee is the legal, registered owner of the shares.
 
If you are a member of a retirement or savings plan or other similar plan, you may submit your voting instructions by Internet, telephone or mail by following the instructions included with your voting instruction card. The deadline for submitting your voting instructions by Internet or telephone is 11:59 p.m., Eastern Daylight Time, on June 2, 2008. The trustee or administrator of the plan will vote according to your instructions and the rules of the plan.
 
Can I change my vote after I return my proxy or voting instruction card?
 
If you are a registered shareholder, you may revoke or change your vote at any time before the proxy card is voted by filing with our secretary either a written notice of revocation or a duly executed proxy bearing a later date. If at the meeting, you request from the judge of elections, your proxy holder’s power to vote will be suspended and you may submit another proxy or vote by ballot. Your attendance at the meeting will not by itself revoke a previously granted proxy.
 
If your shares are held in “street name” or you are a member of a retirement or savings plan or other similar plan, please check your voting instruction card or contact your broker, nominee, trustee or administrator to determine whether you will be able to revoke or change your vote.
 
Will my vote be confidential?
 
It is our policy to maintain the confidentiality of proxy cards, ballots and voting tabulations that identify individual shareholders except as may be necessary to meet any applicable legal requirements and, in the case of any contested proxy solicitation, as may be necessary to allow proper parties to verify proxies presented by any person and the results of the voting.
 
What are the board’s recommendations?
 
The board recommends that you vote:
 
  •  For election of the nominated slate of directors (see proposal 1); and
 
  •  For ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2008 (see proposal 2).

What vote is required to approve each proposal?
 
Election of directors.  Directors are elected by a plurality of votes cast. This means that the three directors receiving the most votes cast at the meeting will be elected to serve for the next three years. Only votes cast “for” are counted in determining whether a plurality has been cast in favor of a director. A properly executed proxy marked “withhold authority” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated. Votes to withhold authority, while included for purposes of attaining a quorum, will have no effect on the vote on this matter.
 
Other proposals.  For each other proposal, the affirmative vote of a majority of the votes cast will be required for approval. Abstentions, while included for purposes of attaining a quorum, will have no effect on the outcome of the proposal.
 
Street name shares and broker non-votes.  If you hold your shares in “street name” through a broker or other nominee, your broker or nominee may not be permitted to exercise voting discretion with respect to some proposals. “Broker non-votes” are shares as to which a broker or nominee does not vote because it does not have discretionary authority to vote. For this meeting, if you do not give specific instructions, your broker or nominee may cast your vote in its discretion for proposal 1, the election of directors, and for proposal 2, the ratification of the appointment of the company’s independent registered public accounting firm. Broker non-votes, if any, are included for purposes of attaining a quorum. On proposals where brokers do not have discretionary voting authority, broker non-votes will have no effect on the outcome of a proposal.
 
GOVERNANCE OF THE COMPANY
 
Where can I find information about the company’s governance?
 
The company has adopted corporate governance guidelines that, along with the charters of the board committees, provide the framework for the governance of the company. The nominating and corporate governance committee is responsible for periodically reviewing the guidelines and recommending any proposed changes to the board for approval. A copy of the corporate governance guidelines is posted on our website (www.InterDigital.com/investor_relations) under the heading “Corporate Governance,” along with the charters of our board committees, our Code of Business Conduct and Ethics and other information about our governance practices. We will provide to any person without charge a copy of these documents upon written request to our secretary at 781 Third Avenue, King of Prussia, Pennsylvania 19406-1409.
 
Director Independence
 
How does the board determine which directors are considered independent?
 
Each year prior to the annual meeting, the board reviews and assesses the independence of its directors and makes a determination as to the independence of each director based on the recommendation of the nominating and corporate governance committee. During this review, the board considers transactions and relationships between each director or any member of his or her immediate family and our company and its subsidiaries and affiliates. The board measures these transactions and relationships against the independence requirements of The Nasdaq Stock Market LLC (Nasdaq). As a result of this review, the board affirmatively determined that Messrs. Campagna, Clontz, Kamins, Roath and Shaner are “independent” in accordance with applicable Nasdaq listing standards. To our knowledge, none of the independent directors has any direct or indirect relationships with our company or its subsidiaries and affiliates, other than serving as a director.
 
Board Leadership
 
Who is the Chairman of the Board?
 
Mr. Campagna, who is an independent director, has served as chairman of the board since April 1996.

Board Structure and Committee Membership
 
How is the board made up?
 
Our articles of incorporation provide for a board consisting of three classes of directors with overlapping three-year terms. One class of directors is elected each year with a term extending to the third succeeding annual meeting after election. The board presently has seven directors.
 
How often did the board meet during 2007?
 
The board met nine times during 2007. Each director is expected to attend each meeting of the board and of those committees on which he serves. No director attended less than 75% of the aggregate of all board meetings and meetings of committees on which the director served during 2007. We usually schedule meetings of the board on a day next to our annual meeting, and when this schedule is followed, it is the policy of the board that directors are expected to attend our annual meeting. All directors attended the annual meeting of shareholders in June 2007, except for Mr. Clontz and Mr. Shaner.
 
The company’s corporate governance guidelines provide that the independent directors meet in executive session at regular intervals or as otherwise appropriate throughout the year. The independent directors met in executive session two times during 2007.
 
What is the role of the primary board committees?
 
The board has standing audit, compensation, finance and investment, nominating and corporate governance and executive committees, which are composed entirely of independent directors, as determined by the board in accordance with applicable Nasdaq listing standards. In addition, audit committee members meet additional, heightened independence criteria applicable to audit committee members under applicable Nasdaq listing standards. Each of the audit, compensation, finance and investment, and nominating and corporate governance committees operates under a written charter, which has been approved by the board. The table below provides information about the current membership of the committees and the number of meetings held in 2007.

This excludes from consideration officers of companies in direct or substantial competition with our company and major or potential major customers, suppliers or contractors.
 
The committee evaluates director candidates recommended by shareholders based on the same criteria used to evaluate candidates from other sources.

Audit Committee Pre-Approval Policy for Audit and Non-Audit Services
of Independent Registered Public Accounting Firm
 
The audit committee’s policy requires that it pre-approve all audit and non-audit services to be performed by the company’s independent registered public accounting firm so that the provision of such services does not impair the firm’s independence. Unless a service falls within a category of services that the audit committee has pre-approved, an engagement to provide the service requires pre-approval by the audit committee. Also, proposed services exceeding pre-approved cost levels require specific pre-approval.
 
Consistent with the rules established by the SEC, proposed services to be provided by the company’s independent registered public accounting firm are evaluated by grouping the service fees under one of the following four categories: Audit Services, Audit-Related Services, Tax Services and All Other Services. All proposed services are discussed and approved by the audit committee. In order to render approval, the audit committee has available a schedule of services and fees approved by category for the current year for reference and specific details are provided. The audit committee does not pre-approve services related only to the broad categories noted above.
 
The audit committee has delegated pre-approval authority to its chairman for cases where services must be expedited. The company’s management provides the audit committee with reports of all pre-approved services and related fees by category incurred during the current fiscal year with forecasts of additional services anticipated during the year.
 
All of the services related to fees disclosed above were pre-approved by the audit committee.

REPORT OF THE AUDIT COMMITTEE
 
Our audit committee is composed of four directors whom the board has determined meet the independence and financial literacy requirements of Nasdaq, including additional heightened independence criteria applicable to audit committee members under applicable Nasdaq listing standards. The committee has, for many years, been composed entirely of independent directors. We act pursuant to our charter, which was adopted by the board and is subject to annual review.
 
As more fully described in the charter, the committee oversees the company’s financial reporting process on behalf of the board. In fulfilling our oversight responsibilities, the audit committee has reviewed and discussed with management the company’s audited consolidated financial statements for the year ending December 31, 2007, including a discussion of the acceptability and appropriateness of significant accounting principles and management’s assessment of the effectiveness of the company’s internal controls over financial reporting. Management has represented to us that the company’s consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States and considered appropriate in the circumstances to present fairly the company’s financial position, results of operations and cash flows. The audit committee has also reviewed and discussed with PwC, the company’s independent registered public accounting firm, their evaluation of the company’s internal controls over financial reporting and other business matters. Further, the audit committee has discussed with PwC the matters required to be discussed with the independent registered public accounting firm by Statement on Auditing Standards No. 61 (communications with audit committees), as amended and adopted by the Public Company Accounting Oversight Board (PCAOB) in Rule 3200T.
 
This committee has also received and reviewed the written disclosures and the letter from PwC required by the Independence Standards Board standard No. 1 (independence discussions with audit committees), as adopted by the PCAOB in Rule 3600T, which relates to the accountant’s independence from the company and its related entities, and has discussed with PwC their independence from the company.
 
Based on the reviews and discussions with management and the independent registered public accounting firm referred to above, we recommended to the board that the audited financial statements be included in the company’s annual report on Form 10-K for the year ending December 31, 2007 for filing with the SEC and we retained PwC as the company’s independent registered public accounting firm for the year ending December 31, 2008.
 
AUDIT COMMITTEE:
 
Robert S. Roath, Chairman
Steven T. Clontz
Edward Kamins
Robert W. Shaner
 
How are directors compensated?
 
For board participation during fiscal year 2007, our non-management directors each received annual base compensation of $25,000. They each also received committee participation compensation equal to $5,000 annually ($15,000 annually for service as chairman of the executive, compensation, finance and investment, and nominating and corporate governance committees and $30,000 annually for service as chairman of the audit committee). Our chairman of the board receives 10,000 restricted stock units (RSUs) (all vesting one year from the grant date) each year on January 15th (or the next preceding trading day if the 15th is not a trading day). In addition, each non-management director receives 2,000 RSUs (all vesting one year from the grant date) at each annual meeting, except that all non-management directors that are re-elected at an annual meeting receive 6,000 RSUs (2,000 vesting each year beginning at the first anniversary of such re-election). All cash payments are based upon service for a full year and prorated payments are made for service less than a full year. These payments are made on a quarterly basis; however, cash payments and RSU awards may be

deferred. An election to defer must be made in the calendar year preceding the year in which services are rendered and the compensation is earned.
 
The compensation committee is responsible for reviewing and making recommendations to the board about compensation for non-management directors. In 2007, the committee retained Compensation Strategies, Inc. (CSI), to conduct a market review of the company’s compensation program for non-management directors. CSI reports directly to the compensation committee. CSI assessed the competitiveness of the company’s director compensation as measured against a peer group recommended by CSI and presented its conclusions to the committee in June 2007. After reviewing the information provided by CSI, including CSI’s conclusion that the company’s director compensation was close to the median among companies in the peer group, the compensation committee concluded that no changes were necessary for 2007 and ratified the company’s annual compensation program for non-management directors effective as of January 1, 2007. In addition to conducting periodic market reviews of the company’s non-management director compensation, CSI discusses major shifts in the marketplace for director compensation with the committee or management, as appropriate, as these shifts occur from time to time. In addition, at least annually, CSI discusses with the chief administrative officer any variables that may affect director compensation to assist the company in its ongoing efforts to provide a compensation program for non-management directors that is competitive. Additional information about CSI appears below under the heading “Role of Compensation Committee, Executive Officers and Compensation Consultant in Compensation Decisions.”
 
To align the interests of directors with those of our shareholders, the company has adopted stock ownership guidelines for directors. Individuals are expected to meet their targets within five years of the date they become subject to the guidelines. Stock ownership guidelines applicable to the non-management directors are set at a target of three times their annual cash retainer. Qualifying ownership includes common stock, restricted stock and RSUs. All non-management directors were in compliance with the guidelines as of December 31, 2007.

EXECUTIVE COMPENSATION
 
Compensation Committee Report
 
The compensation committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management, and based on its review and discussions has recommended to the board of directors that the Compensation Discussion and Analysis be included in this 2008 proxy statement.
 
COMPENSATION COMMITTEE: 
 
Harry G. Campagna, Chairman
Steven T. Clontz
Robert S. Roath
Robert W. Shaner
 
Compensation Discussion and Analysis
 
This Compensation Discussion and Analysis focuses on the company’s compensation strategy, programs and practices for 2007 for the executive officers named in the Summary Compensation Table (named executive officers) that follows this discussion.
 
Compensation Objectives and Philosophy
 
The compensation and benefits provided to the company’s named executive officers generally have, as their primary purpose, the attraction, retention and motivation of talented employees who will drive the execution of the company’s strategic plan, encourage stock ownership and create long-term value for shareholders.
 
The core objectives of the company’s compensation program are to:
 
  •  Provide a uniform and equitable means of recognizing and rewarding named executive officers based on their individual and collective contributions to company, departmental and individual goals with an overarching “pay for performance” philosophy;
 
  •  Provide that all elements of our compensation program (base pay, incentive compensation, equity awards) remain competitive through regular assessments of market conditions, the use of industry-specific surveys, and routine benchmarking of peer company compensation practices and programs; and
 
  •  Incorporate flexibility in order to meet the rapidly changing market dynamics of the telecommunications industry.
 
The company’s total compensation program is part of an overall strategy to create an environment of collective effort towards common goals, to give each named executive officer a short- and long-term stake in the success of the company, and to reward named executive officers appropriately when company performance meets or exceeds desired objectives. It is the compensation committee’s view that each named executive officer plays a key role in the successful execution of the company’s strategy.
 
Role of Compensation Committee, Executive Officers and Compensation Consultant in Compensation Decisions
 
The compensation committee determines the structure and amount of all named executive officer compensation. The committee has final authority with respect to these compensation decisions. The committee considers the recommendations of the chairman of the board in determining the base salary of the chief executive officer and the individual performance component of his annual bonus. As part of the annual performance and compensation review for our named executive officers other than the chief executive officer,


14


Table of Contents

the committee considers the chief executive officer’s assessment of each named executive officer’s individual performance, including identification of major individual accomplishments, and his recommendations with respect to their compensation. In addition, the chief executive officer provides an assessment to the compensation committee regarding the extent to which the company achieved corporate goals established under the company’s Annual Employee Bonus Plan and the Long Term Compensation Program (LTCP). From time to time, the compensation committee may also receive information from other executive officers about matters such as compensation trends and changes in the law that may impact the terms of the company’s compensation plans.
 
The compensation committee has retained CSI to assist the committee by providing relevant market data (including peer group benchmarking) and by making recommendations to the committee regarding the structure and amounts of various components of executive compensation. CSI reports directly to the compensation committee. As discussed above under the heading “How are directors compensated?,” CSI conducts periodic market reviews of the company’s non-management director compensation and provides other advice to the committee on director compensation matters. In addition, from time to time, CSI may advise the board and management on ad hoc basis about discrete compensation-related issues. In May 2006, at the compensation committee’s direction, CSI conducted a market review of the company’s compensation levels for its senior executives. As discussed in more detail below, CSI assessed the competitiveness of the company’s named executive officer compensation as measured against a peer group recommended by CSI.
 
Elements of Executive Compensation — Overview
 
The various elements of our compensation program are designed to promote specific compensation objectives, with a view toward furthering the three core objectives of the program, which are described above. The company’s compensation program for its named executive officers includes a mix of current and long-term compensation, both of which have cash and equity components.
 
The basic components of the named executive officers’ current compensation are:
 
  •  Base salary;
 
  •  Annual bonus;
 
  •  401(k) match;
 
  •  Profit-sharing; and
 
  •  Cash supplemental payment.
 
Long-term compensation for the named executive officers is paid out under the LTCP, as more fully described below. The LTCP has two components: (1) equity (in the form of time and performance-based RSUs), and (2) a long-term incentive cash award based on the achievement of corporate goals after the completion of cycles that are generally three years in length.
 
The company does not provide pension or deferred compensation programs to named executive officers, although they have the ability to defer settlement of RSUs. Perquisites (i.e., car allowances, club memberships, etc.) are not paid to any named executive officer. In lieu of perquisites and as a retention incentive, every employee, including the named executive officers, receives a cash supplemental payment equal to 31/2% of the employee’s base salary, as discussed further below under “Cash Supplement and Profit-Sharing Program.” The named executive officers participate in a variety of savings, health and welfare plans which are available to all U.S. employees.
 
The company has not established formal goals or policies for allocating between cash and non-cash compensation for our named executive officers. Similarly, the company has not established formal goals or policies for allocating between current and long-term compensation for our named executive officers. Instead, we believe that the structures of the Annual Employee Bonus Plan and the LTCP, as described in more detail below, result in allocations that are market-competitive, fair and reasonable in this regard.

Current Compensation
 
Base Salary
 
Base salary is the guaranteed element of a named executive officer’s annual cash compensation. Base salaries for the company’s named executive officers are designed to attract and retain highly qualified individuals. The compensation committee approves base salaries for the named executive officers annually based on the committee’s assessment of each named executive officer’s individual performance during the prior year and his or her experience and scope of responsibilities within the company. The committee also considers salaries paid to similarly situated executives within the company’s peer group, and information on changes in the Consumer Price Index provided by management.
 
In 2007, salary adjustments for our named executive officers were based primarily on individual performance and peer group data. Individual adjustments were made after the compensation committee considered the performance of each executive together with job tenure, individual responsibilities, the unique nature of certain positions, and other elements of the individual’s annual cash, total and projected compensation. Salary adjustments for 2007 resulted in an increase of approximately 9% for Mr. Merritt and 4% for each of the other named executive officers, except Mr. McQuilkin, who joined the company in July 2007, and Mr. Shay, whose salary increased by approximately 14% due to a one-time payment of $25,000 in April 2007 based on Mr. Shay’s assumption of management oversight for the company’s patent litigation matters.
 
Annual Bonuses
 
Bonus awards are designed to reward the achievement of annual business goals, reward the individual accomplishments of the named executive officers and encourage stock ownership. Bonuses are payable to named executive officers under the company’s Annual Employee Bonus Plan. The targeted annual bonus of each of the company’s named executive officers is set as a percentage of salary. For 2007, that percentage was 57% for the chief executive officer and 40% for the other named executive officers. The amount awarded is based 75% on achievement of annual corporate goals and 25% on individual performance. Distinctions in compensation among the named executive officers have tended to be reflected in the portion of the bonus award attributable to individual performance.

In 2007, the corporate goals were securing additional patent licenses, securing patent/technology licenses providing a specified amount of revenue, managing cash spending to a specified level, building the product business and enhancing the company’s intellectual property portfolio, and strengthening the organization. The specific goals, and the relative weights assigned to each, were as follows:
 
             
Goal
 
Description
  Target Weight  
 
Top 5 3G handset license
  The number of licensees licensed in the year correspond to the attainment of 0% to 300% of the designated target weight percentage     25 %
Non-top 5 handset license
  The number of licensees licensed in the year correspond to the attainment of 0% to 100% of the designated target weight percentage     10 %
Revenue generation outside patent licensing
  The number of modem IP licensees licensed in the year correspond to the attainment of 0% to 100% of the designated target weight percentage     10 %
Cash burn
  Excluding litigation, arbitration, commissions and other non-operational expenses, hold cash spending below a specified dollar amount to attain between 0% and 100% of the designated target weight percentage     15 %
Product business growth
  Complete the ASIC on schedule, secure necessary strategic partners, and reach meaningful commercial discussions with potential customers to attain between 0% and 100% of the designated target weight percentage     14 %
Acquisitions/investments
  Build pipeline of acquisition/investment opportunities customers to attain between 0% and 100% of the designated target weight percentage     8 %
IPR positioning
  Obtain a minimum number of patented or patentable contributions accepted into the various standards bodies applicable to the company to attain between 0% and 100% of the designated target weight percentage     10 %
Organizational development
  Complete and implement development plans, rotational assignments and annual organizational reviews to attain between 0% and 100% of the designated target weight percentage     8 %
TOTAL
        100 %
 
The annual corporate goals are generally structured to challenge management to achieve results that collectively yield a payout at or about 100% of target. However, there tends to be less certainty associated with the company’s ability to achieve goals relating to the execution of patent license and technology agreements consistent with the company’s strategic plan. At the end of 2007, the chief executive officer provided his assessment to the compensation committee regarding the extent to which the company achieved the annual corporate goals. The committee considered this assessment and discussed various other factors that contributed to the company’s successes in areas not identified in the goals enumerated under the plan. These successes included standards submissions well beyond the level anticipated in the annual corporate goals, certain key product development achievements, the company’s 2007 corporate reorganization, proactive litigation management, and management’s overall effective communication with the board. Following discussion among the members, the compensation committee determined that the company achieved 83% of the 2007 annual corporate goals.
 
In determining annual bonuses for 2007, the compensation committee considered the recommendations of the chairman of the board and reviewed the individual performance component of the chief executive officer’s bonus. For the other named executive officers (excluding Mr. Fagan, who did not receive an annual bonus due to his departure), the compensation committee reviewed the performance assessments provided by the chief executive officer. The compensation committee also has discretion to exercise its judgment based on interactions with each named executive officer. As noted above, the amount awarded as annual bonus is based 75% on achievement of annual corporate goals and 25% on individual performance. The payout under the


17


Table of Contents

portion of the annual bonus attributable to individual performance may range from 0 to 150% of the targeted annual bonus amount, depending upon the individual executive’s performance assessment.
 
Since 1999, the compensation committee has determined that 30% of the annual bonus paid to employees at the vice president level and above, including the named executive officers, be paid in the form of shares of the company’s common stock, which are subject to a two-year restriction on transferability. The purpose of paying a portion of the annual bonus in the form of equity is to enhance senior management stock ownership, thereby fostering the alignment of senior management’s interests with those of our shareholders. Due to the restriction on transfer, the officers also receive a tax gross-up on the value of these bonus shares, which is intended to ensure that the amount of the officers’ annual bonus equals what they otherwise would have received if the bonus were payable entirely in cash.
 
Savings and Protection Plan (401(k))
 
The company’s Savings and Protection Plan is a tax-qualified retirement saving plan pursuant to which employees, including the named executive officers, are able to contribute the lesser of 100% of their annual base salary or the limit prescribed by the Internal Revenue Service (IRS) on a pre-tax basis. The company provides a 50% match, paid in shares of company common stock, on the first 6% of an employee’s salary contributed to the 401(k) plan, up to the cap mandated by the IRS.
 
Cash Supplement and Profit-Sharing Program
 
The cash supplemental payment provides all employees, including the named executive officers, with an annual cash payment equal to 31/2% of their annual base salary, payable quarterly. This program is designed to eliminate the need to provide any perquisites to employees and to serve as a retention incentive. Effective January 1, 2008, all executive level employees, including the named executive officers, have elected not to participate in the cash supplemental payment program for 2008.
 
In addition, the compensation committee approved a profit-sharing contribution to each employee, including the named executive officers, of 1% of the employee’s base salary up to a cap of $225,000 for 2007, which has been paid in shares of company common stock in the first quarter of 2008.
 
Long-Term Incentives
 
The company’s LTCP is designed to incentivize the executive team to achieve strong corporate performance aligned with the company’s long-term strategic plan, to align the interests of the named executive officers with shareholders, and to attract and retain highly qualified individuals. The LTCP is comprised of both equity and cash components that include:
 
  •  Performance-based and time-based RSU awards; and
 
  •  A performance-based cash award.
 
The LTCP consists of three-year, overlapping cycles. The first cycle under the program covered the period from April 1, 2004 through January 1, 2006 (Cycle 1) and included both RSU and cash components. The second cycle originally covered the period from January 1, 2005 through January 1, 2008 (Cycle 2) and also included both RSU and cash components. In the second quarter of 2005, the compensation committee amended the LTCP to revise only the cash award portion of Cycle 2 to cover a 31/2 year period from July 1, 2005 through January 1, 2009 (Cycle 2a). The compensation committee amended the LTCP because it believed that several events, including the conclusion of a major arbitration that would have had a significant one-time effect on achievement of corporate goals, and the appointment of a new chief executive officer, warranted the establishment of new long-term goals, and because the parallel cycles that previously existed resulted in erratic expense patterns for the company every other year. The RSU component of the third cycle (RSU Cycle 3) began on January 1, 2007 and runs through January 1, 2010; the cash component of the third cycle (Cash Cycle 3) began on January 1, 2008 and runs through January 1, 2011.

Participants may earn a pro-rata portion of their awards under the LTCP in the event of death, disability, retirement or if the company terminates their employment without cause. Participants also may earn their full awards in the event of a “change in control.”
 
Equity Awards
 
Each named executive officer receives an RSU award under the LTCP based on a percentage of their base salary at the time of grant. Awards under the LTCP are paid out at the end of each three-year cycle for all executive participants. Until 2006, the equity component of the LTCP consisted solely of time-based RSUs. To more closely align management’s compensation with corporate performance, in August 2006, members of senior management were offered the opportunity to exchange 50% of their then-current time-based RSUs (from Cycle 2) for an equal number of performance-based RSUs, with the level of payout tied to the company’s achievement of pre-approved performance goals established by the compensation committee. All the named executive officers participated in this exchange offer, other than Mr. McQuilkin, who joined the company in July 2007 and was therefore not eligible to participate in the LTCP’s Cycle 2 equity award program. In December 2006, the LTCP was amended so that, beginning with the January 1, 2007 grant (RSU Cycle 3), executives now receive 50% of their RSU grant as performance-based RSUs and 50% as time-based RSUs.
 
Under the performance-based RSU component of the LTCP, 100% achievement of the corporate goals set by the compensation committee results in a 100% payout of the performance-based RSU incentive target amounts. For each 1% change above or below 100% achievement, the actual award amount is adjusted by four percentage points, with a minimum payout of 80% of target and a maximum payout of 300%. For performance that falls below 80% of target, no RSU payout would occur.
 
Cycle 2
 
The amount of the RSU grant (both time and performance-based) made January 1, 2005 (Cycle 2), for each named executive officer (other than Mr. McQuilkin, who did not join the company until July 2007), was based on the following percentages of base salary:
 
         
    Percentage of
 
Named Executive Officer
  Base Salary  
 
William J. Merritt
    120 %
Bruce G. Bernstein
    80 %*
Mark A. Lemmo
    90 %
Lawrence F. Shay
    80 %
Richard J. Fagan
    90 %**
 
 
Mr. Bernstein joined the company in June 2005, at which time his prorated award was calculated using 80% of his base salary.
 
** Mr. Fagan’s original Cycle 2 RSU grant (both time and performance-based) was subsequently pro-rated based on his departure date.
 
For Cycle 2, in order to receive a payout under the performance-based equity component of the LTCP, the company had to achieve the associated goal, involving the execution of certain agreements providing revenue from 3G terminal units, by January 15, 2008. This goal was structured to challenge management to achieve a sufficient number and type of agreements to result in a payout at or about 100% of target. The compensation committee reviewed progress toward this goal as of January 15, 2008 and authorized a payout at the 20% level. The time-based portion of the Cycle 2 RSU grant vested in full on January 1, 2008.

Cycle 3
 
The amount of the RSU grant (both time and performance-based) made January 1, 2007 (RSU Cycle 3), for each named executive officer was based on the following percentages of base salary:
 
         
    Percentage of
 
Named Executive Officer
  Base Salary  
 
William J. Merritt
    120 %
Scott A. McQuilkin
    80 %*
Bruce G. Bernstein
    80 %
Mark A. Lemmo
    90 %
Lawrence F. Shay
    90 %
Richard J. Fagan
    90 %**
 
 
* Mr. McQuilkin’s prorated RSU award under RSU Cycle 3 was based on 80% of his salary on July 9, 2007, his date of hire.
 
** Mr. Fagan’s RSU award under this cycle has since been cancelled due to his departure.
 
The goals associated with RSU Cycle 3, which began on January 1, 2007, focus on elements of the company’s strategic plan that relate to our technology solutions and fabrication-outsourced products and are comprised of: (1) number of design wins (50% of goal), and (2) the volume of fabrication-outsourced or IP customer unit shipments made within the performance period (50% of goal). The payout may exceed or be less than the targeted percentage of base salary depending on the company’s level of goal achievement, or there may be no payout at all if the company fails to meet the minimum performance goals for the cycle.
 
Effective with his promotion on January 1, 2008, to executive vice president of intellectual property and chief intellectual property counsel, Mr. Shay’s base salary percentage, which will be used for future RSU award calculations, was increased from 90% to 100%. All executive officers (other than Mr. Merritt and Mr. Shay) will have a target RSU award of 90% of base salary in future program cycles once they have served in their respective capacities for three consecutive years. Mr. Merritt’s target RSU award percentage is higher than that of the other named executive officers due to his position as president and chief executive officer of the company.
 
Cash Awards
 
The cash portion of the LTCP provides performance-based cash awards to the named executive officers based on the company’s achievement of pre-approved performance goals established by the compensation committee for each program cycle. As with the equity component discussed above, each participant’s target award is established as a percentage of their base salary in effect at the start of each cycle and a payout is based on the company’s achievement of the applicable long-term goals. For Cycle 2a, the percentages of July 1, 2005 base salaries used to calculate the LTCP cash awards were as follows:
 
         
Named Executive Officer
  Percentage of Base Salary  
 
William J. Merritt
    120 %
Scott A. McQuilkin
    80 %*
Bruce G. Bernstein
    80 %
Mark A. Lemmo
    90 %
Lawrence F. Shay
    80 %
Richard J. Fagan
    90 %**
 
 
* Mr. McQuilkin’s prorated award under Cycle 2a was based on 80% of his salary on July 9, 2007, his date of hire.
 
** Mr. Fagan’s award under this cycle has been prorated to his departure date.

Table of Contents

 
The objectives underlying the goals established for the Cycle 2a cash award are to drive the company’s strategic plan and complement the annual bonus plan goals. The goals associated with Cycle 2a are: (1) to achieve patent licensing/technology solution revenue coverage at a specified target percentage of the 3G market on terms consistent with our strategic plan; (2) generate a specified amount of free cash flow over the period; and (3) expand the company’s business beyond 3G baseband through execution of additional agreements.
 
The LTCP cash goals are generally structured to challenge management to achieve results that collectively yield a payout at or about 100% of target. The payout may exceed or be less than the targeted percentage of base salary depending on the company’s level of goal achievement, or there may be no payout at all if the company fails to meet the minimum performance goals for the cycle.
 
Factors Considered in Setting Compensation
 
In establishing compensation for the named executive officers, the compensation committee exercises its judgment after considering the following factors:
 
  •  Company performance relative to established corporate goals;
 
  •  Compensation levels at our peer group companies; and
 
  •  The individual performance of the named executive officers.
 
In evaluating the accomplishment of 2007 goals and related compensation awards for named executive officers, the compensation committee considered the company’s strong performance during 2007. During 2007, the company delivered solid financial results, significantly matured the patent licensing business, and successfully brought the SlimChip family of mobile broadband modem solutions to market. The compensation committee also considered the extent to which the company achieved corporate goals established under the company’s Annual Employee Bonus Plan and the LTCP, as well as the chief executive officer’s assessment regarding the company’s achievement of the corporate goals. The committee determined that the company achieved 83% of the 2007 corporate goals under the Annual Employee Bonus Plan.
 
The compensation committee also considered the compensation practices of other companies in the telecommunications/communications industry. Consistent with the core objectives of the company’s compensation program, the compensation committee seeks to provide compensation that is competitive in light of current market conditions and industry practices. Accordingly, the compensation committee reviews data on peer group companies to gain a general perspective on the compensation levels and practices at these companies and to assess the relative competitiveness of the compensation paid to the company’s named executive officers. The peer group data serve as a reference point and guideline for the compensation committee in evaluating competitiveness; the committee does not target compensation for individual named executive officers to specific benchmarks. As discussed above, the compensation committee has engaged CSI to assist it in the process of identifying peer group companies and gathering information on their practices. As part of the market review conducted in 2006, CSI identified a peer group that included 17 companies generally from the technology/communications industry sector, including several companies that had patent/licensing components to their businesses. The peer group companies had annual revenues ranging from $70 million to


21


Table of Contents

$1.1 billion, with median revenue of approximately $235 million, which is slightly larger than the company’s revenues of $163 million for the previous fiscal year. The companies comprising the peer group were:
 
     
Critical Path, Inc.
  Anaren, Inc.
Globecomm Systems Inc.
  Rambus Inc.
Stratex Networks, Inc.
  DSP Group, Inc.
Macrovision Corporation
  CalAmp Corp.
C-COR Incorporated
  Harmonic Inc.
Comtech Telecommunications Corp.
  Infospace, Inc.
Viasat, Inc.
  Tekelec
REMEC, Inc.
  Powerwave Technologies, Inc.
Headwaters Incorporate
   
 
CSI gathered available information about individual positions, elements of compensation and overall compensation at the peer group companies and provided the compensation committee with this data, which the compensation committee reviewed. Overall, total compensation for the company’s named executive officers was close to the median (+/− 5%) for companies in the $150 million — $200 million revenue group. Although the compensation committee does not specifically target the median in setting compensation for the named executive officers, the company’s practice has been to pay at the median for comparable roles in the marketplace in order to attract, retain and motivate talented leaders.
 
The third factor that the compensation committee considered in determining compensation for our named executive officers in 2007 was individual performance, including the chief executive officer’s assessment of the other named executive officers’ individual performance. The compensation committee considered individual performance when setting both base salaries and the amount of the named executive officers’ annual bonuses which, as discussed below, are based 25% on individual performance. Specifically:
 
  •  With respect to Mr. Merritt, the company’s president and chief executive officer, the compensation committee considered that Mr. Merritt continued to perform an outstanding job in leading the company and running its business in 2007. In addition, Mr. Merritt was responsible for overseeing a number of high-profile litigation matters and working to bring these matters to a resolution. Mr. Merritt also was successful in moving certain important product initiatives forward, including the SlimChip design program. In addition to Mr. Merritt’s individual accomplishments during 2007, the compensation committee considered that his salary for 2006 was on the lower end of the salary range for chief executives in the company’s peer group.
 
  •  With respect to Mr. Bernstein, the company’s chief intellectual property officer, the compensation committee considered that Mr. Bernstein has displayed excellent technical and communication skills. Mr. Bernstein’s major accomplishments in 2007 included resolving two key patent licensing issues, effectively managing important litigation matters, and developing strong contacts in the patent community.
 
  •  With respect to Mr. McQuilkin, the company’s chief financial officer, in determining the amount of Mr. McQuilkin’s annual bonus for 2007, the compensation committee considered that Mr. McQuilkin substantially upgraded the company’s strategic valuation process and business modeling. The committee also considered his success in strengthening the finance organization and bringing a heightened sense of fiscal discipline to the company. The compensation committee approved the base salary of Mr. McQuilkin in advance of his joining the company in July 2007. Factors that the compensation committee considered in determining Mr. McQuilkin’s base salary included his compensation package at his prior position, prevailing market rates, and internal consistency relative to compensation of the company’s other named executive officers.
 
  •  With respect to Mr. Lemmo, the company’s executive vice president, business development and product management, the compensation committee considered that Mr. Lemmo demonstrated strong deal-making skills and a solid understanding of market dynamics. In addition, Mr. Lemmo was effective in


22


Table of Contents

  advocating for the company’s products in the marketplace, including playing a significant role in positioning the company’s semiconductor business in the marketplace. Mr. Lemmo also completed a major deal and reached agreement on two additional key deals in 2007.
 
  •  With respect to Mr. Shay, the company’s president, InterDigital patent holding subsidiaries and executive vice president of intellectual property and chief intellectual property counsel, the compensation committee considered that Mr. Shay continued to serve as an outstanding general counsel to the company, demonstrating broad legal knowledge and excellent judgment and decision-making abilities. Mr. Shay also excelled in the government affairs function while continuing to provide counsel to the company, and he assumed management oversight of the company’s patent litigation matters.
 
  •  With respect to Mr. Fagan, former chief financial officer of the company, the compensation committee considered Mr. Fagan’s strong credibility with the investment community, his significantly increased role in strategic planning, particularly financial modeling and capital structure work, and his successful implementation of Sarbanes-Oxley-related internal control initiatives.
 
As a result of these factors, base salary and annual bonuses for the named executive officers increased during 2007 as compared to 2006. Mr. Fagan did not receive an annual bonus for 2007 due to his departure from the company in August 2007.
 
Grant Practices
 
The timing and amount of the grants under the Annual Employee Bonus Plan and the LTCP are formulaic. In the case of the Annual Employee Bonus Plan, as discussed above, the compensation committee has elected, over the past nine years, to award 30% of the annual bonus earned by employees at the vice president level or above, including the named executive officers, in the form of stock, bearing a two-year restriction on transferability. At the direction of the compensation committee, the number of shares awarded is calculated by dividing the applicable dollar amount by the closing fair market value of the company’s common stock on the last business day immediately preceding the payroll date on which bonuses are paid to all employees.
 
In the case of the LTCP, the terms and conditions of the program provide that RSU grant values are calculated as a target percentage of the named executive officer’s base salary at either the beginning of the cycle or their date of hire. This amount is then divided by the fair market value of the company’s common stock at the beginning of the cycle or the date of hire to determine the number of RSUs to be granted. For example, if a named executive officer’s target RSU award value is equal to 90% of a $250,000 base salary (or $225,000), and the closing fair market value of our common stock on the last business day of the year prior to the commencement of a new cycle is $30, the named executive officer would automatically be granted 7,500 RSUs on the first day of the new cycle. Half of the total award, or 3,750 RSUs, would be time-based, with the remaining half being performance-based.
 
The compensation committee believes that the procedures described above for setting the grant date of equity awards provides assurance that the grant timing does not take advantage of material non-public information.
 
2008 Compensation Decisions
 
In January 2008, the compensation committee increased the 2008 base salary for all named executive officers, as described below:
 
  •  William J. Merritt, president & chief executive officer — $500,000
 
  •  Scott A. McQuilkin, chief financial officer — $294,250
 
  •  Bruce G. Bernstein, chief intellectual property officer — $290,400
 
  •  Mark A. Lemmo, executive vice president, business development & product management - $304,365


23


Table of Contents

 
  •  Lawrence F. Shay, president, InterDigital patent holding subsidiaries, executive vice president of intellectual property & chief intellectual property counsel — $310,000
 
The increases in base salaries over 2007 levels are based on the compensation committee’s consideration of the named executive officers’ continued excellent individual performance during 2007, information about compensation levels at peer group companies based on a market review that CSI completed in June 2007, the promotion of Mr. Shay, and changes in the Consumer Price Index. No significant changes were made from 2007 in establishing 2008 performance goals under the Annual Employee Bonus Plan or in the company’s goals for the Cash Cycle 3 under the LTCP, which began on January 1, 2008.
 
Impact of Tax Treatment
 
Section 162(m) of the Internal Revenue Code generally limits the company’s tax deduction for compensation paid to its chief executive officer and other named executive officers (excluding the chief financial officer) to $1 million per person in any tax year. Qualified performance-based compensation is not subject to the deduction limit if specified requirements are met. The compensation committee has considered the effects of Section 162(m) when implementing compensation plans and taking into account whether preserving the tax deductibility of compensation to named executive officers could impair the operation and effectiveness of the company’s compensation programs. However, the committee believes it is important to maintain flexibility to make adjustments in the company’s LTCP, despite the fact that in the future certain amounts paid to executives in excess of $1 million may not be deductible. For 2007, there was no compensation paid in excess of the $1 million threshold under 162(m).
 
Stock Ownership Guidelines
 
To align the interests of senior officers with those of our shareholders, the company has established minimum stock ownership guidelines for senior officers. Individuals are expected to meet their targets within five years of the date they become subject to the guidelines. The compensation committee established the guidelines with the advice of CSI, and the committee monitors compliance with the guidelines on an annual basis. Qualifying ownership includes common stock, including that held through the company’s 401(k) plan, restricted stock and RSUs. The chief executive officer’s target ownership is set at an amount of company common stock equal in value to four times his current annual base salary. Other officers are expected to own company stock approximately equivalent in value to a specified multiple of either one, two or three times their current annual base salary, depending upon their position in the company. All of the named executive officers were in compliance with the guidelines as of December 31, 2007.
 
Employment Agreements
 
The company has entered into employment agreements with each of the named executive officers that provide severance payments and benefits in the event of termination of employment under specified circumstances, including termination of the executive’s employment within one year after a “change of control.” Severance payments and benefits provided under the employment agreements are used to attract and retain executives in a competitive industry that has experienced ongoing consolidation and to ease an individual’s transition in the event of an unexpected termination of employment due to changes in the company’s needs. Information regarding the nature and circumstances of payouts upon termination is provided under the heading “Potential Payments Upon Termination or Change in Control.”

(6) Mr. McQuilkin was hired as chief financial officer and became an executive officer of the company in July 2007.
 
(7) Mr. Bernstein assumed his current position of chief intellectual property officer in January 2008. Compensation for 2006 and 2007 reflects compensation Mr. Bernstein earned as chief intellectual property and licensing officer.
 
(8) Mr. Shay assumed his current position of president, InterDigital patent holding subsidiaries, executive vice president of intellectual property and chief intellectual property counsel in January 2008. Compensation for 2006 and 2007 reflects compensation Mr. Shay earned as chief legal officer and government affairs. In April 2007, the compensation committee approved a one-time payment of $25,000 to Mr. Shay based on Mr. Shay’s assumption of management oversight for the company’s patent litigation matters. This payment is reported as a part of Mr. Shay’s salary for 2007.
 
(9) Mr. Fagan ceased to be an executive officer of the company in August 2007. The negative value reflected under the Stock Awards column for 2007 represents a correction to prior years’ amortization expense related to performance-based RSUs that Mr. Fagan forfeited upon his departure from the company.

(1) Represents the potential annual performance-based incentive cash payments each executive could earn in 2007. These awards were granted under our Annual Employee Bonus Plan. Actual amounts earned in 2007 were based on the 2007 objectives established by the compensation committee at its January 15, 2007 meeting. At the time of the grant, the incentive payment could range from the threshold amount to the maximum amount depending on whether 2007 objectives were met or exceeded. The actual amounts paid in 2008, based on the level of attainment of 2007’s objectives, are set forth in the Summary Compensation Table under the column “Bonus.” The cash-based portion may be determined by multiplying the amount shown by 70%.
 
(2) Represents performance-based RSUs granted under RSU Cycle 3 of the company’s LTCP on January 1, 2007. The number of performance-based RSUs granted in 2007 that will ultimately vest on or around January 15, 2010 could range from the threshold amount to the maximum amount depending on whether the performance objectives established by the compensation committee are met or exceeded.
 
(3) Represents either time-based RSUs or restricted stock.
 
(4) Grant date fair value for time-based RSUs and PSUs is determined in accordance with FAS 123R. This grant date fair value related to RSU awards is expensed over the vesting period of the awards under FAS 123R and is reflected in the Summary Compensation Table in the year it is expensed. See Notes 10 and 11 to our audited financial statements included in our annual reports on Form 10-K for 2007 and 2006, respectively, for the assumptions used in valuing and expensing the RSU awards in accordance with FAS 123R. We do not recognize any expense related to PSU awards until the compensation committee has determined that, at a minimum, target performance has been achieved such that there will be an actual payout. At the time that determination is made, we record a catch-up adjustment through the determination date and recognize the remaining expense over the remaining life of the award.

(1) Commencing in 2004, the awarding of stock options was limited to only newly hired employees. In 2006, the company began awarding only RSUs to newly-hired employees. All option exercise prices reflected in the table above represent 100% of the closing price per share of our common stock on the date of grant. At December 31, 2007, all named executive officer option awards were fully vested and

Table of Contents

exercisable. All option awards reflected in the table above were granted for ten-year terms, ending on the option expiration date set forth in the table.
 
(2) The amounts shown represent awards of time-based RSUs granted to the named executive officers. Except as provided in footnotes (8) and (9), these awards were made pursuant to the company’s LTCP. All awards granted January 1, 2005, as well as Mr. Merritt’s May 5, 2005 award of 4,080 RSUs and Mr. Bernstein’s June 20, 2005 award, vested in full on January 1, 2008, the end date of Cycle 2. All awards granted January 1, 2007, the start date for RSU Cycle 3, are scheduled to vest in full on January 1, 2010.
 
(3) The values shown in this column were determined using a per share price of $23.33, the closing price of our common stock on December 31, 2007.
 
(4) The amounts shown represent awards of performance-based RSUs granted to the named executive officers and were made pursuant to the LTCP. All awards shown as being granted in 2005 vested in full on January 15, 2008 and represent 20% achievement of the original target award. See footnote (6) for additional details related to these awards. Subject to accelerated vesting as described under the caption “Potential Payments on Termination or Change in Control,” performance-based RSUs granted in 2007 vest on or about January 15, 2010 in a range from 0 to 300% of the target values shown based on the achievement of specific performance goals.
 
(5) The values shown in this column were determined using the target level of performance-based RSUs and a per share price of $23.33, the closing price of our common stock on December 31, 2007.
 
(6) In August 2006, the company’s senior management was offered the opportunity to exchange 50% of their then current time-based RSUs awarded under Cycle 2 for an equal number of performance-based RSUs. All named executive officers participated in the exchange offer, other than Mr. McQuilkin, who joined the company in July 2007 and was therefore not eligible to participate in the LTCP’s Cycle 2 equity award program.
 
(7) This amount represents an adjustment to Mr. Merritt’s original January 1, 2005 award resulting from his promotion to president and chief executive officer.
 
(8) This amount represents the remaining unvested portion of a 10,000 RSU “promotion” award granted to Mr. Merritt in connection with his promotion to president and chief executive officer and will vest in May 2008.
 
(9) This amount represents a “new hire” award granted to Mr. McQuilkin in association with his joining the company as chief financial officer. This award will vest annually, in three equal installments, beginning in 2008 on the anniversary of his hire date.
 
(10) These amounts, granted to Mr. McQuilkin on his hire date, represent prorated awards under RSU Cycle 3, which began on January 1, 2007.
 
(11) This amount, granted to Mr. Bernstein on his hire date, represents a prorated award under Cycle 2, which began on January 1, 2005.

(1) The value shown reflects the total pre-tax value realized by the officers (number of shares exercised times the difference between the closing price of our common stock on the exercise date and the exercise price). Value from these option exercises was only realized to the extent our stock price increased relative to the stock price on grant date (the exercise price).
 
(2) The value shown reflects the final pre-tax value realized by the officers upon the vesting of restricted stock or time-based RSUs (number of shares vested times the closing price of our common stock on the vesting date).
 
Potential Payments on Termination or Change in Control
 
Named Executive Officer Employment Agreements
 
Each of the current named executive officers has entered into an employment agreement with the company that provides severance pay and benefits, among other things, in certain events of termination of employment, as described below.
 
Pursuant to the terms of the LTCP, if the executive’s employment terminates in the event of long-term disability, death, absenteeism or without cause (each as described below), the executive is entitled to a pro-rata portion of any RSU awards (both time-based and performance-based) and cash award. Pursuant to the terms of the Annual Employee Bonus Plan that require an employee to be working actively at the time of the payout (unless involuntarily terminated other than for intentional wrongdoing after the end of the plan year, but before the bonus was paid), the executive would not be eligible to receive a bonus under the plan, although we retain the right to make exceptions to the eligibility requirements of the plan and have done so in the past. Any rights that executives have under these plans in connection with other termination scenarios are discussed below in connection with the relevant scenario.
 
Termination for Long-Term Disability
 
The company may terminate the employment of a named executive officer in the event of his long-term disability (as that term is defined in our Long-term Disability Plan), such that he is not otherwise qualified to perform the essential functions of his job either with or without reasonable accommodation. In the event the executive’s employment terminates due to a long-term disability, the executive is entitled to receive:
 
  •  All accrued but unpaid (as of the date of termination) base salary;
 
  •  Benefits that are provided to our similarly situated executive employees, including without limitation, medical and dental coverage, optional 401(k) participation and expense reimbursement (Benefits); and


30


Table of Contents

 
  •  Other forms of compensation and bonus payable or provided in accordance with the terms of any then existing compensation, bonus or benefit plan or arrangement, including payments prescribed under any disability or life insurance plan or arrangement (Other Compensation).
 
In addition, provided that the executive executes our standard termination letter, which includes, among other things, a broad release of all claims against us and a reiteration of his confidentiality and other post-termination obligations (Termination Letter), he is entitled to receive, for a period of one year (18 months in the case of Mr. Merritt) following termination: (1) regular installments of base salary at the rate in effect at the time of termination, reduced by the amount of payments received for this period pursuant to any Social Security entitlement or any long-term disability or any other employee benefit plan, policy or program maintained to provide benefits in the event of disability in which the executive was entitled to participate at the time of termination, and (2) medical and dental coverage on terms and conditions comparable to those most recently provided to him.
 
Termination by Death
 
In the event of the termination of an executive’s employment due to death, the company will pay to the executive’s executors, legal representatives or administrators an amount equal to the accrued but unpaid portion of the executive’s base salary, Benefits and Other Compensation up through the date on which he dies. The executive’s executors, legal representatives or administrators will be entitled to receive the payment prescribed under any death or disability benefits plan in which the executive is a participant as our employee, and to exercise any rights afforded under any compensation or benefit plan then in effect.
 
Termination for Cause
 
The company may terminate an executive’s employment at any time for “cause” upon the occurrence of any of the following: (1) any material breach by the executive of any of his obligations under his employment agreement that is not cured within 30 days after he receives written notification from the company of the breach, or (2) other conduct of the executive’s involving any type of willful misconduct with respect to the company, including, without limitation, fraud, embezzlement, theft or proven dishonesty in the course of his employment or conviction of a felony. In the event of a termination of the executive’s employment for cause, the executive is entitled to receive all accrued but unpaid (as of the effective date of termination) base salary, Benefits and Other Compensation.
 
Pursuant to the terms of the LTCP, the executive forfeits any rights under the LTCP and Annual Employee Bonus Plan if his employment terminates for cause.
 
Termination Without Cause
 
The company may terminate an executive’s employment at any time, for any reason, without cause upon 30 days prior written notice to the executive. In the event of a termination without cause, the executive is entitled to receive all accrued but unpaid (as of the effective date of termination) base salary, Benefits and Other Compensation. In addition, provided he executes a Termination Letter, the executive is entitled to receive: (1) severance in an amount equal to his base salary, and (2) medical and dental coverage on terms and conditions comparable to those most recently provided to him, both for the period of one year (18 months in the case of Mr. Merritt) commencing upon the date of termination. In addition, Mr. Merritt’s employment agreement provides that he is also entitled to receive additional severance equal to the total amount of 50% of his target bonus for the year in which the termination occurs, payable in equal installments over a period of 18 months after the date of termination.
 
Termination for Absenteeism
 
The company may terminate an executive’s employment in the event that he is absent for more than 150 days within any 12-month period. In the event of termination due to absenteeism, the executive is entitled to receive all accrued but unpaid (as of the date of such termination) base salary, Benefits and Other Compensation. In addition, provided he executes a Termination Letter, he is entitled to receive, for a period of

Table of Contents

one year (18 months in the case of Mr. Merritt) following termination: (1) regular installments of base salary at the rate in effect at the time of termination, reduced by the amount of payments received for this period pursuant to any Social Security entitlement or any long-term disability or any other employee benefit plan, policy or program maintained to provide benefits in the event of disability in which the executive was entitled to participate at the time of termination, and (2) medical and dental coverage on terms and conditions comparable to those most recently provided to him. In addition, Mr. Merritt’s employment agreement provides that he is also entitled to receive an additional severance amount equal to the total amount of 50% of his target bonus for the year in which termination occurs, payable in equal installments over a period of 18 months after the date of termination.
 
Termination by the Executive
 
An executive may terminate his employment with us at any time, for “good reason” or without “good reason,” provided that the date of termination is at least 30 days after the date he gives written notice of the termination to the company. For this purpose, “good reason” means: (1) the company’s failure to pay in a timely manner the executive’s base salary or any other material form of compensation or material benefit to be paid or provided to him under his employment agreement, or (2) any other material breach of our obligations under his employment agreement that is not cured within 30 days after the company receives written notification from the executive of the breach. In the event that the executive terminates his employment, either for good reason or without good reason, he is entitled to receive all accrued but unpaid (as of the effective date of termination) base salary, Benefits and Other Compensation. In addition, solely if the termination is for good reason, and provided that the executive executes a Termination Letter, he is entitled to receive: (1) severance in an amount equal to his base salary, and (2) medical and dental coverage on terms and conditions comparable to those most recently provided to him, both for the period of one year (18 months in the case of Mr. Merritt) commencing upon the date of termination.
 
In addition, Mr. Merritt’s employment agreement provides that he is also entitled to receive additional severance equal to the total amount of 50% of his target bonus for the year in which termination occurs, payable in equal installments over a period of 18 months after the date of termination. Pursuant to the terms of the LTCP and Annual Employee Bonus Plan, Mr. Merritt forfeits any rights under these plans if he terminates his employment for any reason. If an executive other than Mr. Merritt terminates his employment with us without good reason, the company generally may elect to pay severance of up to one year’s salary and continuation of medical and dental benefits for a period of one year.
 
Termination Following a Change in Control
 
If the company terminations an executive’s employment (except for cause), or the executive terminates his employment with us (whether or not for good reason) within one year following a “change in control,” he is entitled to receive all accrued but unpaid (as of the effective date of termination) base salary, Benefits and Other Compensation. In addition, (1) provided that he executes a Termination Letter, the executive is entitled to receive, on the date of termination, an amount equal to two years’ worth of his base salary, and (2) all stock options granted by the company that vest upon a change in control pursuant to the terms of the applicable stock option plan. For this purpose “change in control” means the acquisition (including by merger or consolidation, or by our issuance of securities) by one or more persons in one transaction or a series of related transactions, of more than 50% of the voting power represented by our outstanding stock on the date of the executive’s employment agreement, or a sale of substantially all of our assets.
 
Pursuant to the terms of the LTCP, following a change in control (except for cause), the executive is entitled to an early payout of his LTCP cash bonus award in an amount that is the greater of either: (1) his target LTCP bonus, or (2) the LTCP cash bonus that would have been due to him at the end of the relevant LTCP cycle (but for the change in control), assuming performance through the remainder of the cycle prior to the change in control. In addition, for each executive, the occurrence of a change in control causes all otherwise unvested time-based RSUs (whether granted as an LTCP, promotion or new hire award), and any other unvested equity awards, with the exception of performance-based RSU awards, to vest immediately in

full. These actions will occur without regard to whether the executive remains employed at the company and without regard to performance during the remainder of the LTCP cycles.
 
Pursuant to the terms of the Annual Employee Bonus Plan, the executive is not eligible to receive a bonus under the Annual Employee Bonus Plan, with the exception of Mr. Shay, who is entitled to receive 100% of his annual target bonus amount.
 
Termination Due to Retirement
 
The company’s retirement eligibility age is 70. For purposes of determining eligibility, the company employs a formula that sums the employee’s years of service and age. For each of the named executive officers, successfully meeting this eligibility requirement causes the vesting, on a pro-rata basis, of all otherwise unvested RSUs. For time-based RSUs, the pro-rated amount of RSUs will be determined by multiplying the full time-based award amount by a fraction equal to the portion of the vesting period that had transpired prior to the cessation of employment. For performance-based RSUs, the pro-rated amount will be determined as described above, but not until the LTCP cycle has completed and a determination has been made regarding performance against established goals.
 
Potential Payments upon Termination or Change in Control
 
The following tables reflect the amount of compensation payable to each of the named executive officers, with the exception of Mr. Fagan, pursuant to each of their employment agreements, as well as pursuant to the LTCP and Annual Employee Bonus Plan upon: (1) termination for long-term disability; (2) termination by death; (3) termination for cause; (4) termination without cause; (5) termination for absenteeism; (6) termination by the executive; and (7) termination upon a change in control of the company. The amounts shown assume that the termination was effective as of December 31, 2007, and thus include amounts earned through that time. The amounts reflected are estimates of the amounts that would be paid out to the executives upon their termination. The actual amounts to be paid out can be determined only at the time the events described above actually occur.
 
The compensation Mr. Fagan received upon his departure from the company is fully reflected in the Summary Compensation Table above. In response to Mr. Fagan’s March 2007 announcement that he would be resigning from the company as chief financial officer no later than August 15, 2007, the company and Mr. Fagan entered into an amended and restated employment agreement to set forth the terms of his continuing employment until that time. The terms of his employment agreement provided for the payment of separation benefits in the event that Mr. Fagan remained with us through August 15, 2007, that his employment ended prior to that date as a result of his disability or death, that we terminated him without cause prior to that date, or that we terminated his employment (except for cause) after a change in control; provided that Mr. Fagan or his estate (if his termination was by reason of his death) executed a Termination Letter. The separation benefits included: (1) regular payments of his base salary through August 15, 2007; (2) payment of our portion of the premiums for his continued participation in our group health insurance (medical, dental, vision) pursuant to COBRA for the period from the last day of his employment through December 31, 2007; (3) a pro rata portion of his RSU awards (both time-based and performance-based) under the LTCP for Cycle 2 (which extended from January 1, 2005 through January 1, 2008); (4) a pro rata portion of any LTCP cash award for Cycle 2; and (5) removal of the restrictions relating to the bonus restricted stock awards that were granted to him for 2005 and 2006 under the Annual Employee Bonus Plan and delivery of the shares as promptly as possible. Mr. Fagan continues to be subject to a one-year covenant-not-to-compete regardless of the reason for termination and independent of any obligation the company may have to pay severance.

Additional Employment Agreement Provisions
 
Salaries

Post-Termination Obligations
 
Each of the named executive officers is bound by certain confidentiality obligations, which extend indefinitely, and by certain non-competition and non-solicitation covenants, which, with respect to each of Messrs. Merritt and Bernstein, extend for a period of one year following termination of his employment for any reason and independent of any obligation the company may have to pay him severance, and, with respect to each of Messrs. McQuilkin, Lemmo and Shay extend (as applicable): (1) for the period, if any, that he receives severance under his employment agreement, (2) in the event his employment terminates for cause, a period of one year following termination, or (3) in the event that he terminates his employment without good reason, so long as we voluntarily pay severance to him (which we are under no obligation to do), for the period that he receives severance, but in no event for a period longer than one year. In addition, each of the named executive officers is bound by certain covenants protecting our right, title and interest in and to certain intellectual property that either has been or is being developed or created in whole or in part by the executive.
 
Taxes
 
In the event any amount or benefit payable to the named executive officer under his employment agreement, or under any other plan, agreement or arrangement applicable to him, is subject to an excise tax imposed under Section 4999 of the Internal Revenue Code, the named executive officer is entitled, in addition to any other amounts payable under the terms of his employment agreement or any other plan, agreement or arrangement, to a cash payment in an amount sufficient to indemnify him (or any other person as may be liable for the payment of the excise tax) for the amount of any such excise tax, and leaving the named executive officer with an amount, net after all federal, state and local taxes, equal to the amount he would have had if no portion of his benefit under the plan constituted an “excess parachute payment.” Notwithstanding the foregoing, the determination of the amount necessary to indemnify the named executive officer will be made taking into account all other payments made to him under any plans, agreements or arrangements aside from his employment agreement that are intended to indemnify him with respect to excise taxes on “excess parachute payments.”

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
The company has a written statement of policy with respect to related person transactions, which is administered by the audit committee of our board of directors. Under our policy, a “Related Person Transaction” is any transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) between the company (including any of our subsidiaries) and a related person, in which the Related Person had, has or will have a direct or indirect material interest. A “Related Person” includes any of our executive officers, directors or director nominees, any stockholder owning in excess of 5% of our common stock, any immediate family member of any of the foregoing persons, and any firm, corporation or other entity in which any of the foregoing persons is employed as an executive officer or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest. Related Person Transactions do not include any transactions involving only director or executive officer compensation, transactions where the Related Person receives proportional benefits as a shareholder with all other shareholders, transactions involving competitive bids, or transactions involving certain bank-related services.
 
Pursuant to our policy, a Related Person Transaction may be consummated or may continue only if:
 
  •  The audit committee approves or ratifies the transaction in accordance with the terms of the policy; or
 
  •  The chairman of the audit committee pre-approves or ratifies the transaction and the amount involved in the transaction is less than $100,000, provided that for the Related Person Transaction to continue it must be approved by the audit committee at its next regularly scheduled meeting.
 
It is the company’s policy to enter into or ratify Related Person Transactions only when the board, acting through the audit committee, determines that the Related Person Transaction in question is in, or is not inconsistent with, the best interests of the company, including but not limited to situations where the company may obtain products or services of a nature, quantity or quality, or on other terms, that are not readily

Table of Contents

available from alternative sources or when the company provides products or services to Related Persons on an arm’s length basis on terms comparable to those provided to unrelated third parties or on terms comparable to those provided to employees generally.
 
In determining whether to approve or ratify a Related Person Transaction, the committee takes into account, among other factors it deems appropriate, whether the related party transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the Related Person’s interest in the transaction.
 
There were no related person transactions or proposed related person transactions during 2007.
 
OTHER MATTERS
 
Section 16(a) Beneficial Ownership Reporting Compliance
 
Did all directors and executive officers comply with Section 16(a) reporting requirements?
 
Based upon a review of filings with the SEC and written representations that no other reports were required, we believe that all of our directors and executive officers complied during 2007 with the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934.
 
Shareholder Proposals
 
How may shareholders make proposals or director nominations for the 2009 annual meeting?
 
Shareholders interested in submitting a proposal for inclusion in the proxy statement for the 2009 annual meeting may do so by submitting the proposal in writing to our secretary at InterDigital, Inc., 781 Third Avenue, King of Prussia, Pennsylvania 19406-1409. To be eligible for inclusion in our proxy statement, shareholder proposals must be received no later than December 30, 2008, and they must comply with all applicable SEC requirements. The submission of a shareholder proposal does not guarantee that it will be included in the proxy statement.
 
Our bylaws also establish an advance notice procedure with regard to nominations of persons for election to the board and shareholder proposals that are not submitted for inclusion in the proxy statement but that a shareholder instead wishes to present directly at an annual meeting. Shareholder proposals and nominations may not be brought before the 2009 annual meeting unless, among other things, the shareholder’s submission contains certain information concerning the proposal or the nominee, as the case may be, and other information specified in our bylaws, and we receive the shareholder’s submission no earlier than the close of business on March 6, 2009, and no later than April 6, 2009. However, if the date of our 2009 annual meeting is more than 30 days before or more than 60 days after the anniversary of our 2008 annual meeting, this information must be delivered not earlier than the close of business on the 120th day prior to the 2009 annual meeting and not later than the close of business on the later of the 90th day prior to the annual meeting or the 10th day following the day on which we first publicly announce the date of the 2009 annual meeting. Proposals or nominations not meeting these requirements will not be entertained at the 2009 annual meeting. A copy of the full text of these bylaw provisions may be obtained on our website (www.InterDigital.com/investor_relations) under the heading “Corporate Governance,” or by writing to our secretary at 781 Third Avenue, King of Prussia, Pennsylvania 19406-1409.
 
Proxy Solicitation Costs and Potential Savings
 
Who pays for the proxy solicitation costs?
 
We will bear the entire cost of proxy solicitation, including preparation, assembly, printing and mailing of this proxy statement, the proxy card and any additional materials furnished to shareholders. Copies of proxy solicitation material will be furnished to brokerage houses, fiduciaries and custodians holding shares in their names, which are beneficially owned by others to forward to such beneficial owners. In addition, we may reimburse such persons for their cost of forwarding the solicitation material to such beneficial owners. One or

more of telephone, email, telegram, facsimile or personal solicitation by our directors, officers or regular employees may supplement solicitation of proxies by mail. No additional compensation will be paid for such services. We may engage the services of a professional proxy solicitation firm to aid in the solicitation of proxies from certain brokers, bank nominees and other institutional owners. Last year, the company engaged the Altman Group for this purpose at a cost of approximately $2,300.
 
What is “householding” of proxy materials and can it save the company money?
 
The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy materials with respect to two or more shareholders sharing the same address by delivering a single annual report and proxy statement, or notice of Internet Availability of Proxy Materials, to those shareholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders and cost savings for companies. Although we do not household for registered shareholders, a number of brokerage firms have instituted householding for shares held in “street name,” delivering a single set of proxy materials to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, now or in the future, you no longer wish to participate in householding and would prefer to receive a separate annual report and proxy statement, please notify us by calling (610) 878-7866 or by sending a written request to our secretary at 781 Third Avenue, King of Prussia, Pennsylvania 19406-1409, and we will promptly deliver a separate copy of our annual report and proxy statement. If you are receiving multiple copies of the annual report and proxy statement and wish to receive only one, please notify your broker.
 
Annual Report on Form 10-K
 
How will I receive the annual report?
 
We have mailed the annual report booklet together with the notice of our annual meeting, this proxy statement and your proxy card.
 
We will provide to any shareholder without charge a copy of the 2007 annual report on Form 10-K upon written request to our secretary at 781 Third Avenue, King of Prussia, Pennsylvania 19406-1409. Our annual report booklet, 2007 annual report on Form 10-K (including exhibits thereto) and this proxy statement are also available on our website (www.InterDigital.com/investor_relations).
 
Other Business
 
Will there be any other business conducted at the annual meeting?
 
As of the date of this proxy statement, we know of no business that will be presented for consideration at the annual meeting other than the items referred to in this proxy statement. If any other matter is properly brought before the meeting for action by shareholders, proxies in the enclosed form returned to us will be voted in accordance with the recommendation of the board or, in the absence of such a recommendation, in accordance with the judgment of the proxy holder.
