Item 5.  Other Events.

        The presiding Federal District Court Judge in the patent infringement
        lawsuit involving the Company, its wholly-owned subsidiary, InterDigital
        Technology Corporation and Ericsson Radio Systems Inc. has ruled upon
        Certain pre-trial motions.

        As previously reported in the Company's filings with the Securities and
        Exchange Commission, each party has filed pre-trial motions with the
        Court under seal seeking to limit issues at trial and to dismiss the
        other party's case in whole or in part. The Judge has ruled on portions
        of the pre-trial motions of both parties, removing certain patent claims
        from further consideration with regard to the infringement issues in the
        District Court case, the effect of which is to narrow the issues
        remaining for trial. The Company believes these rulings, which remain
        under Court seal, do not materially affect the relief sought by
        InterDigital Technology Corporation. Court ordered mediation continues
        and no trial date has been set.

         This Report contains a forward-looking statement reflecting
         InterDigital's current belief that the Court's rulings do not
         materially affect the relief sought by InterDigital Technology
         Corporation. Such a statement is subject to a variety of risks and
         uncertainties including, but not limited to, the potential that a
         reduction in the number of asserted patent claims could adversely
         impact a jury's view of appropriate relief, any future rulings on
         remaining pre-trial motions which are adverse to InterDigital, and
         other uncertainties associated with any litigation.

     Pursuant to the requirements of the Securities Exchange Act of 1934, the
Registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.

                                      INTERDIGITAL COMMUNICATIONS CORPORATION
