Exhibit 99.1


                        Federal Judge Confirms Award for
             InterDigital in Dispute with Nokia over Royalties Owed


    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--Dec. 28, 2005--InterDigital
Communications Corporation (Nasdaq:IDCC), a leading designer,
developer and provider of wireless technology and product platforms,
today announced that the federal district court judge presiding in the
enforcement proceeding between InterDigital and Nokia Corporation
(Nokia) in the United States District Court for the Southern District
of New York confirmed in its entirety the Final Award rendered in June
2005 by the Arbitral Tribunal operating under the auspices of
International Court of Arbitration of the International Chamber of
Commerce (ICC).
    "I am pleased with today's court decision," commented William J.
Merritt, President and Chief Executive Officer of InterDigital. "We
have always believed that any challenge to the Final Award would
ultimately fail. In rejecting all of Nokia's arguments, the federal
court confirmed our belief. With yet another legal challenge
dismissed, we are hopeful that Nokia will finally comply with its
signed license agreement with InterDigital. If not, we will continue
to pursue all legal remedies to secure payment. In that vein, as we
announced yesterday, we have taken action to utilize the contractual
dispute resolution process with Nokia in order to accelerate the
resolution of any outstanding issues that Nokia might allege. We
remain confident that Nokia will pay the amounts due, either of its
own accord or by court order."
    In June 2005, the Arbitral Tribunal 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. The Tribunal
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 at the time of the
Final Award, InterDigital estimated that Nokia's royalty obligations
for covered infrastructure and handset sales from January 1, 2002
through December 31, 2006 would be in the range of approximately $232
million to $252 million. 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. On July 1, 2005, InterDigital initiated the
enforcement action decided today in order to convert the Final Award
into a court judgment which would allow InterDigital, if necessary, to
compel compliance with the Final Award. Nokia failed to comply with
the terms of the Final Award and instead sought to have the Award
vacated.

    Note to editors:

    In February 1999, Nokia entered into agreements with InterDigital
which covered both technology development and a patent license
agreement. As part of the patent license agreement, Nokia paid $31.5
million up front to InterDigital to cover product sales through the
end of 2001. Royalties owed after 2001 could be defined through direct
negotiation, or by a patent license agreement with a designated major
competitor, typically referred to as a Most Favored Licensee clause, a
customary licensing term in the industry. Patent licensing agreements
signed in March 2003 between InterDigital and Ericsson and Sony
Ericsson established the framework for Nokia's royalty obligations for
2G and 2.5G handset and infrastructure sales. After these patent
licensing agreements were signed, InterDigital notified Nokia of its
royalty payment obligations. Nokia disagreed with InterDigital's
interpretation of the impact of these patent licensing agreements and
requested binding arbitration in July 2003 to resolve the dispute.
    In June 2005, the Arbitral Tribunal delivered its Final Award in
the arbitration proceeding between InterDigital Communications
Corporation, ITC, and Nokia. The Tribunal 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 in July 2005, InterDigital estimated
Nokia's royalty obligations for covered infrastructure and handset
sales from January 1, 2002 through December 31, 2003 to be
approximately $112 million. In addition, InterDigital estimated
royalty obligations for covered infrastructure and handset sales for
the period January 1, 2004 through December 31, 2006 to 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, made in July 2005, were 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.
InterDigital has not updated such estimates or underlying assumptions.
