 Exhibit 10.77 
  
 May 20, 2005 
  
 Charles R. Tilden 
  
 Re: Severance Agreement and General Release 
  
 Dear Rip: 
  
 We are interested in resolving amicably your separation of employment with InterDigital Communications Corporation (“the Company”), effective May 2, 2005 (“Termination Date”). Toward this end, we
propose the following Severance Agreement, which includes a General Release (“Agreement”). 
  
 The terms and conditions set forth in Paragraph 1 below will apply regardless of whether you elect to sign this Agreement. However, the severance payments
and other benefits set forth in Paragraph 2 below are contingent on your signing this Agreement. 
  
 You may consider for forty-five (45) days whether you wish to sign this Agreement. You are encouraged to review the proposed Agreement with your attorney.

  
 1. As noted above, regardless of whether you sign this
Agreement: 
  
 (a) Your last day of employment
will be your Termination Date. You will be paid for all time worked up to and including your Termination Date. 
  
 (b) You will be paid for accrued but unused Paid Time Off (PTO) on the next regular pay period following payroll’s receipt of your
final timesheet, in accordance with Company policy. 
  
 (c) Your eligibility to participate in Company sponsored medical, dental and/or vision insurance plans will cease effective your last day of employment. However, you will be eligible to continue such benefits, at your sole expense, pursuant
to the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), subject to COBRA’s terms, conditions and restrictions. (Please see Paragraph 2(b) below for what will occur in the event you sign this Agreement.) 
  
 (d) Your participation in all other Company sponsored group
benefits including group life, disability and accidental death and dismemberment coverage will cease effective your last day of employment. However, you may be eligible to convert your life insurance coverage to a private policy, at your sole
expense, subject to the insurer’s terms, conditions and restrictions. If you wish to convert your life insurance policy to a private policy, please contact Human Resources to receive the appropriate paperwork. 
  
 (e) Your participation in the Company’s 401(k) Savings
Plan or Employee Stock Purchase Plan shall cease effective your Termination Date. You will receive detailed 










 
information from the Company’s 401K Plan provider (Diversified Investment Advisors) regarding your 401(k) Plan fund status and disbursement options.

  
 (f) Your participation in the Company’s
Flexible Reimbursement Account will cease effective your Termination Date. You will have a set amount of time following your last day of employment to submit claims for reimbursement under this Plan. Details will be provided by Human Resources.

  
 (g) All vested stock options previously
granted to you by the Board will terminate in accordance with the terms of the applicable Stock Option Plan under which they were granted. Any non-vested options will terminate effective your last day of employment. A schedule setting forth your
holdings has been provided to you. You are responsible for reviewing the applicable Stock Option Plan and Option Grant and determining the expiration date of your options. If you need assistance, please contact the Company’s stock plan
administrator. 
  
 (h) You will receive a
pro-rata portion of your LTIP cash bonus and RSU award in accordance with the terms of the InterDigital Communications Corporation Long Term Compensation Program. 
  
 (i) The restricted stock granted as part of your annual bonus in the last two fiscal years will remain
restricted as to transferability as set forth in the related award agreements. 
  
 2. If you sign this Agreement, agreeing to be bound by the General Release set forth in Paragraph 3 below and the other terms and conditions of this Agreement, the Company agrees as follows, intending to be legally
bound: 
  
 (a) To pay thirteen (13) months of
severance pay at your current rate of base salary as of your last day of employment, less withholding of all applicable federal, state and local taxes. The severance payments will be paid to you in accordance with the Company’s regular payroll
practices through the end of February 2006 and the remainder will be paid to you in a lump sum prior to March 15, 2006, provided, however your covenant not to compete under section 8 of your Employment Agreement shall remain in effect until May 2,
2006. The first severance payment will be made to you consistent with the first regular pay period following the expiration of the Revocation Period set forth in paragraph 18 below, provided that the Company has received an executed copy of this
Agreement. 
  
 (b) To pay the “designated
portion” of the premiums with regard to your continued participation in the Company’s group health insurance (medical, dental and vision) pursuant to COBRA for a period of thirteen months, provided that you continue to have your co-payment
withheld from your severance pay or otherwise pay it. Thereafter, your continued participation in the Company’s group health plan pursuant to COBRA shall be at your sole expense. For purposes of this provision, the “designated
portion” shall be the portion of the premium which the Company paid at the time of your termination, as the same may be adjusted upon the beginning of the new benefits plan year. Your execution of this Agreement confirms that upon receipt of
the COBRA enrollment forms you will elect to continue coverage and you 

  

 2 








 
authorize the deduction of the applicable co-payment from your severance pay, unless you notify Human Resources, in writing, of your intent not to elect
COBRA. 
  
 (c) To immediately following the
Revocation Period lift the restrictions on transferability on the shares of restricted stock referenced in paragraph 1.(i) above. 
  
 3. You will be provided with outplacement services designed for executive level personnel for a period of 6 months if you so request. Thereafter, you may
extend the outplacement, at the Company’s expense, for up to two immediately subsequent three (3) month periods if you have not accepted an offer of employment. 
  
 4. In consideration for the Company’s payments and other benefits set forth above in Paragraph 2, you agree, intending
to be legally bound, to release and forever discharge the Company and its related or affiliated companies, and each of their past, present and future officers, directors, attorneys, employees, owners, partners, insurers, benefit plan fiduciaries and
agents, and their respective successors and assigns in such capacities (collectively “Releasees”), jointly and severally, from any and all actions, complaints, causes of action, lawsuits or claims of any kind (collectively
“Claims”), known or unknown, asserted or unasserted, which you, your heirs, agents, successors or assigns ever had, now have or hereafter may have against any Releasee arising out of any matter, occurrence, omission or event existing or
occurring prior to your execution of this Agreement, including, without limitation: any claims relating to or arising out of your employment with and/or termination of employment by the Company and/or any of its related and/or affiliated companies;
any claims for unpaid or withheld wages, severance, benefits, bonuses, commissions and/or other compensation of any kind; any claims for reimbursement of expenses of any kind; any claims arising under the Employee Retirement Income Security Act;
any claims for attorneys’ fees, costs or expenses; any claims of discrimination and/or harassment based on age, sex, race, religion, color, creed, disability, handicap, citizenship, national origin, ancestry, sexual orientation, or any other
factor protected by Federal, State or Local law (such as the Age Discrimination in Employment Act, 29 U.S.C. §621 et. sec ., Title VII of the Civil Rights Act of 1964, as amended, the Americans with Disabilities Act, the Pennsylvania Human
Relations Act and the New York Human Rights Law) and any claims for retaliation thereunder; any claims under the Family Medical Leave Act or any other federal, state or local laws governing leaves of absence; any claims under the National Labor
Relations Act; any claims for violation of public policy; any claims arising under the Sarbanes-Oxley Act of 2002, as amended from time to time; any claims for retaliation and/or any whistleblower claims; any claims for emotional distress or pain
and suffering; and/or any other statutory or common law claims, now existing or hereinafter recognized, known or unknown, including, but not limited to, breach of contract, libel, slander, fraud, wrongful discharge, promissory estoppel, equitable
estoppel and misrepresentation. 
  
 5. You acknowledge and agree
that the Company’s severance payments and other benefits under Paragraph 2 above are adequate consideration to support your General Release in Paragraph 3 above. 
  
 6. Nothing in this Agreement shall result in (a) the forfeiture of any vested benefits, or waive any Claims with
regard to any vested benefits, under any Company 401 (k) Savings 

  

 3 








 
Plan, Employee Stock Purchase Plan or other deferred compensation plans or (b) waiver of any rights to indemnification or coverage under director and officer
liability insurance policies. 
  
 7. Regardless of whether you
execute this Agreement, you are prohibited from using or disclosing, directly or indirectly, for you own benefit or the benefit of any person or entity, any of the confidential and proprietary information of the Company (the “Confidential
Information”), except as may be required to be disclosed pursuant to judicial, arbitral or governmental requirement or order, provided you take reasonable steps to give the Company sufficient notice in order to contest such requirement or
order. Such Confidential Information includes but is not limited to, information regarding the Company’s sales and marketing information and techniques, business plans, financial data, trade secrets (including without limitation any technical
information, hardware, software, algorithms, source code, object code, drawings, sketches, designs, processes, procedures, formulae, data, reports, computer programs, charts, improvements and any other technical information or knowledge relating to
the development, design and implementation of the Company’s products and services), pricing lists, supplier lists and other confidential supplier data, customer lists and other confidential customer data, and any other information or knowledge
concerning the Company and its business or others that the Company does business with, whether or not in tangible form, that is not otherwise publicly available. Further, you are required to execute further documents or instruments required for
patent prosecution. You are reminded of your obligations under Sections 6, 7 and 8 of your Employment Agreement dated November 18, 1996 (as amended April 6, 2000) as well as your obligations under your Non-Disclosure and Assignment of Ideas
Agreement dated as of February 28, 2005. Sections 6, 7, 8, 10 and 21 of your Employment Agreement survive termination of your employment as well as your obligations under your Non-Disclosure and Assignment of Ideas Agreement dated as of February 28,
2005, regardless of whether you execute this Agreement. The Restricted Period under Section 8 of your Employment Agreement shall be one year irrespective of the timing of severance payments hereunder and it is further clarified that you may
provide services during the Restricted Period to the noncompetitive portion of an entity which is engaged in a business activity competitive with the Company’s Business or the business of any of the Company’s subsidiaries or affiliates
provided you have obtained the prior written consent of the Company, not to be unreasonably withheld or delayed. Under such permitted circumstances you are not limited with respect to your receipt of compensatory equity in the entire Permitted
Entity. In addition, Section 8(d)(ii) does not apply to serving as a reference provided it is not for purposes of employing or retaining a current or former employee of the Company at your then current business during the Restricted Period.

  
 8. You agree that in the event you receive a request or
demand, orally, in writing, electronically or otherwise, for the disclosure or production of information which you acquired in the course of your employment which is not generally known by or readily accessible to the public, you must notify
immediately, in writing, via certified mail, the Company’s General Counsel at the following address: 781 Third Avenue, King of Prussia, Pennsylvania 19406. Any and all documents (written or electronic) in your possession or control
relating to the request or demand shall be included with the notification. You shall wait a minimum of ten (10) days (or the maximum time permitted by such legal process, if less) after sending the letter before making a disclosure or production to
give the Company time to determine whether the disclosure or production involves confidential and/or proprietary information, in which event the Company may seek to prohibit and/or restrict the production and/or disclosure and/or to obtain a
protective 

  

 4 








 
order with regard thereto. This provision covers, but is not limited to, requests or demands in connection with judicial, administrative, arbitration and all
other adversarial proceedings. If the request or demand is in conjunction with judicial, administrative, arbitration or other adversarial proceedings, copies of all correspondence regarding the request or demand shall be included with the
information sent to the General Counsel. The foregoing shall not prohibit you from complying with legal process when, by way of example, the Company fails to obtain a protective order prohibiting disclosure or production of documents. 
  
 9. Prior to the termination of your employment and as a condition precedent
to receiving the payments and other benefits set forth in paragraph 2 above, you must return to the Company, retaining no copies, all Confidential Information, keys, documents, correspondence, access cards, computer equipment, computer tapes
and diskettes, manuals, engineering notebooks, customer information, and any other property and information in either printed or electronic formats which you obtained as a result of or in connection with your employment by the Company.
Notwithstanding the foregoing, you may retain and utilize copies of your rolodex and other similar address books. 
  
 10. You agree that you will not make any negative comments or disparaging remarks, in writing, orally or electronically, about the Company or any other
Releasee and their respective officers, directors, shareholders, employees and agents and their respective products and services. The Company agrees that it and its executive officers and directors, acting in such capacities, shall not make any
negative comments or disparaging remarks, in any public statement or public filing nor to any prospective employer provided that all communication between the Company and such prospective employer shall be exclusively with the Chief Human Resources
Officer, Gary Isaacs. However, nothing in this Agreement shall be interpreted to restrict your right and obligation to testify truthfully or to make normal competitive statements as to products and services in the course of your future employment
provided such statements do not violate your obligations with respect to Confidential Information and such employment does not violate your obligations under section 8 of your Employment Agreement. Further, nothing in this Agreement will prevent the
Company from making truthful statements about you in any legal or administrative proceeding, to any governmental agency which regulates the Company or its business or in any legally required securities filing. 
  
 11. In response to any inquiries by employees of the Company or third parties
concerning any of the terms or circumstances of your termination, you agree (i) that you will state only that your employment with and position as a director of the Company have terminated by mutual agreement or to state information publicly
disclosed by the Company, whether in press releases, public filings or otherwise, or (ii) if information publicly disclosed by the Company, whether in press releases, public filings or otherwise, concerning this Agreement or the terms or
circumstances of your termination is inaccurate in any material respect, you may respond to the inquiry with accurate corrective information so long as you have previously notified the Company of the material inaccuracy and requested the Company to
issue a corrective disclosure and the Company has failed to issue such a corrective disclosure within five days of your notification and request. 
  
 12. While you are not prevented from applying for employment or reemployment with the Company or any related or affiliated company, in the event that you
seek employment 

  

 5 








 
and/or reemployment, the Company or any related or affiliated company shall have no obligation to employ you or reemploy you, and the failure or refusal to
employ you or reemploy you shall not be deemed unlawful retaliation or discrimination against you. 
  
 13. This Agreement may be amended only in writing signed by you and me, Sr. Human Resources Officer, of the Company. 
  
 14. This Agreement shall be governed by and construed in accordance with the
laws of the Commonwealth of Pennsylvania, without reference to conflicts of law principles. 
  
 15. Nothing in this Agreement shall be construed as an admission or concession of liability or wrongdoing by the Company or any other Releasee. Rather, the proposed Agreement is being offered for the sole purpose of
settling amicably any and all possible disputes between the parties. 
  
 16. If any provision in this Agreement or the application thereof is construed to be overbroad, then the court making such determination shall have the authority to narrow the provision as necessary to make it enforceable and the provision
shall then be enforceable in its narrowed form. In the event that any provision in this Agreement is determined to be legally invalid or unenforceable by any court of competent jurisdiction and cannot be modified to be enforceable, the affected
provision(s) shall be stricken from the Agreement, and the remaining terms of the Agreement and its enforceability shall remain unaffected thereby. 
  
 17. You agree and represent that: 
  
 (a) You have read carefully the terms of this Agreement, including the General Release; 
  
 (b) You have had an opportunity to and have been encouraged
to review this Agreement, including the General Release, with an attorney;

federal holiday, then the letter must be post-marked on the following business day. If you revoke this Agreement on a timely basis, you shall not be eligible for the payments and other benefits set forth in paragraph 2 above. 
  
 19. As noted above, you have 45 days to decide whether you wish to execute
