              InterDigital Updates Guidance for Second Quarter 2005


    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--July 28, 2005--InterDigital
Communications Corporation (Nasdaq:IDCC), a leading designer,
developer and provider of wireless technology and product platforms,
today announced that it expects second quarter 2005 revenue to be
approximately $38.0 million and operating expenses to be approximately
10% lower than first quarter 2005.
    The updated guidance for revenue corresponds to the higher end of
the range given in May 2005; at that time, InterDigital's revenue
guidance anticipated a range of $37.2 million to $38.5 million for
second quarter 2005.
    Previously, the company indicated that the level of expenses for
second quarter 2005 would be similar to first quarter 2005 level,
which totaled $36.3 million. The decrease in expenses is based on a
number of factors, including the previously announced structural
changes to the second cycle (2005 - 2008) of the performance-based
element of the long-term compensation program, adjustments to expense
accruals related to the first cycle (2004 - 2005) of the program, and
a decrease in arbitration-related expenses. The decline in expenses
was partially offset by previously reported severance costs related to
management changes.
    InterDigital will release its second quarter 2005 financial
results before the market opens on Thursday, August 4, 2005. The
company will host a conference call on Thursday, August 4, 2005 at
10:00 a.m. Eastern Time to discuss its second quarter performance and
other company matters. For access to the conference call within the
U.S. please dial (877) 505-0448 by 9:50 a.m. Eastern Time on August 4
and ask the operator for the InterDigital financial call. InterDigital
also will provide live access to the call on its web site at:
