Exhibit 99.1

               InterDigital and Nokia Enter Arbitration

    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--July 22, 2003--InterDigital
Communications Corporation (Nasdaq: IDCC), a leading architect,
designer and provider of wireless technology and product platforms,
today announced that Nokia Corporation (Nokia) has requested binding
arbitration regarding Nokia's royalty payment obligations for its
worldwide sales of 2G GSM/TDMA (2G) and 2.5G GSM/GPRS/TDMA (2.5G)
products under the existing patent license agreement with InterDigital
Technology Corporation (ITC), a wholly-owned subsidiary of
InterDigital Communications Corporation. Pursuant to the dispute
resolution provisions of the patent license agreement, Nokia's request
for arbitration was filed in the International Court of Arbitration of
the International Chamber of Commerce (ICC).
    Nokia's arbitration request relates to ITC's claim that the patent
license agreements ITC signed with Ericsson and Sony Ericsson in March
2003 defined the financial terms under which Nokia would be required
to pay royalties on its worldwide sale of 2G and 2.5G products
commencing January 1, 2002. Nokia is seeking a determination that it
has no royalty obligations to ITC based upon ITC's licensing of
Ericsson and Sony Ericsson. Alternatively, Nokia is seeking an order
requiring ITC to provide Nokia with access to various documents
related to previous litigations, negotiations, and arbitrations with
other parties. Pending access to the requested documents, Nokia is
seeking to prevent the commencement of arbitration proceedings that
would determine royalty amounts owed to ITC for the period starting
January 1, 2002.
    ITC has thirty days to respond to Nokia's request for arbitration.
As part of ITC's response, ITC intends to file a counterclaim seeking
a determination of and award for royalties owed to ITC by Nokia.
Separately, Nokia has indicated that it intends to file an action in
Federal Court to gain access to documents previously sealed by the
Court related to the now-settled Ericsson litigation.
    "Resolving royalty issues with Nokia remains a top priority," said
William J. Merritt, Executive Vice President, General Patent Counsel
and President of ITC. "We believe that we have fully satisfied our
contractual obligations and remain confident in our position,
including our prior projections as to the amount of royalties owed and
to be paid. We are fully prepared to move forward to arbitration."
