Exhibit 99.1


                InterDigital Receives Final Award in Arbitration
                       Proceeding with Nokia Corporation


           KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--July 1, 2005--InterDigital
Communications Corporation (Nasdaq:IDCC), a leading designer,
developer and provider of wireless technology and product platforms,
today announced that the Arbitral Tribunal operating under the
auspices of the International Court of Arbitration of the
International Chamber of Commerce (ICC) has delivered its Final Award
in the arbitration proceeding between InterDigital Communications
Corporation, InterDigital Technology Corporation (ITC), one of the
company's wholly-owned subsidiaries, and Nokia Corporation (Nokia).
The Tribunal has established royalty rates which are applicable to
Nokia's sales of covered products for the period beginning January 1,
2002 through December 31, 2006 and reflect Nokia's leading market
position. Based on the royalty rates established by the Tribunal,
InterDigital estimates that Nokia's royalty obligations for covered
infrastructure and handset sales from January 1, 2002 through December
31, 2003 will be approximately $112 million. In addition, InterDigital
estimates that royalty obligations for covered infrastructure and
handset sales for the period January 1, 2004 through December 31, 2006
will be in the range of $120 million to $140 million depending upon
whether Nokia avails itself of a prepayment option for the eighteen
month period from July 1, 2005 through December 31, 2006. The above
amounts are exclusive of awarded interest, net of any applicable
contractual discount and based on Nokia achieving sales volume that
entitles Nokia to obtain the lowest applicable royalty rate. Estimates
of post-2003 royalty obligations are based on third party and
InterDigital's estimates of Nokia's sales of covered products for the
applicable periods and InterDigital's assumptions as to market
forecasts and Nokia's sales mix, selling prices and market share.
           The Final Award relates to Nokia's royalty obligations on its
worldwide sales of 2G GSM/TDMA and 2.5G GSM/GPRS/EDGE products under
its existing patent license agreement with ITC. The company expects to
recognize revenue associated with the Final Award after all criteria
for revenue recognition have been met.
           "We are pleased with the Tribunal's decision," said Harry G.
Campagna, InterDigital's Chairman of the Board. "I would like to thank
the many talented people both inside InterDigital and outside the
company who remained steadfast in their resolve and tireless in their
support of this effort."
           William J. Merritt, InterDigital's President and Chief Executive
Officer, added, "While Nokia maintained a very aggressive position in
this matter, we are hopeful that Nokia will comply with its
contractual requirements and pay past and future amounts owed.
Nonetheless, to enforce the ICC's decision, today we filed an action
against Nokia in the U.S. District Court for the Southern District of
New York."
           InterDigital continues to be a party to an arbitration proceeding
with Samsung Electronics Co., Ltd. (Samsung) with the evidentiary
hearing scheduled to commence in October 2005. In 2002, Samsung
exercised its most favored licensee rights under its patent license
agreement with InterDigital and elected to have its royalty
obligations be defined by the terms of the Nokia Patent License
Agreement. The company is currently reviewing the impact of the Final
Award on the Samsung patent license agreement, but believes that it
should have a significant impact on Samsung's royalty obligations.
