                 Nokia Agrees to Pay InterDigital $253 Million;

     Companies Resolve Outstanding 2G Royalty Dispute and Related Litigation
   Matters as Well as Royalty Issues on Nokia's 3G Sales to Date; InterDigital
               to Host Conference Call at 9:00 a.m. EDT, April 28


     KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--April 27, 2006--InterDigital
Communications Corporation (Nasdaq:IDCC) announced today that the company and
its wholly-owned subsidiary InterDigital Technology Corporation have reached
agreement with Nokia Corporation resolving the dispute regarding Nokia's royalty
obligations for its sales of 2G TDMA-based products and related litigation
matters. Under the agreement, Nokia is obligated to pay InterDigital a total of
$253 million on or before April 28, 2006. Upon payment, Nokia will have a
paid-up patent license covering sales of 2G TDMA-based products, which consist
mainly of GSM/GPRS/EDGE terminal units and infrastructure. Also, InterDigital
will release Nokia from infringement liability for its worldwide sales of 3G
terminal units and infrastructure through April 26, 2006. The parties have
agreed to terminate their 1999 patent license agreement originally scheduled to
terminate at the end of 2006. As a result, Nokia's sales of 3G products after
April 26, 2006 will be unlicensed. InterDigital expects to continue negotiations
with Nokia on this issue.
     "Throughout this process, we were confident that we would be paid the
amounts owed under the Arbitration Award by agreement or by court order,"
commented William J. Merritt, President and Chief Executive Officer of
InterDigital. "Nokia's payment for its sales of 2G-TDMA based products falls
within the range of our prior disclosures and is consistent with the royalty
rates stated in the Award."
     Regarding future 3G sales, Mr. Merritt added, "We remain hopeful that we
can reach an amicable resolution on this issue on terms acceptable to both
parties. By terminating the current license agreement, the parties have a clean
slate from which to work and resolve 3G issues."
     As part of the agreement, Nokia has agreed to dismiss its appeal filed in
the United States Court of Appeals for the Second Circuit regarding the
Arbitration Award and InterDigital has agreed to withdraw its arbitration demand
recently filed with the International Chamber of Commerce dealing with the
payment of royalties due under the Award. In addition, Nokia has agreed to
withdraw its challenge before the High Court of Justice of England and Wales,
Chancery Division, Patents Court as to three InterDigital TDMA-related patents.
In exchange for its agreement to withdraw its challenge to these patents,
InterDigital has agreed not to assert the three patents (and related non-U.K.
counterparts) involved in that case against Nokia and that Nokia will have a
worldwide paid-up license for single-mode TIA/EIA-95 products.

     Based upon its preliminary review of the accounting treatment for this
matter, InterDigital believes that the entire $253 million payment will be
recognized in its 2006 income statement. The company will provide additional
detailed disclosure upon the completion of its analysis.
