                      InterDigital Raises Royalty Revenue
                        Guidance for Fourth Quarter 2004


    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--Nov. 23, 2004--InterDigital
Communications Corporation (Nasdaq:IDCC), a leading architect,
designer and provider of wireless technology and product platforms,
today announced it is raising its royalty revenue guidance for fourth
quarter 2004.
    InterDigital now expects to report fourth quarter 2004 royalty
revenues from current licensees in the range of $33.3 to $33.6
million. The Company had previously forecast fourth quarter 2004
royalty revenues in excess of $30 million.
    Richard Fagan, InterDigital's Chief Financial Officer, said, "We
are revising our guidance upward as recently received reports from our
licensees indicate that we will record greater than expected royalty
revenue during the fourth quarter. This increase reflects solid sales
of both 2G and 3G products by key licensees."
