Item 8.01 Other Events.

On March 30, 2006, InterDigital  Communications Corporation and its wholly-owned
subsidiary,  InterDigital Technology Corporation  (collectively,  InterDigital),
filed a request for arbitration with the  International  Court of Arbitration of
the International  Chamber of Commerce (ICC) against Nokia  Corporation  (Nokia)
relating to the Award that an ICC Arbitral  Tribunal  rendered in June 2005 (the
Award).

InterDigital  believes  that by failing  to pay  royalties  and  submit  royalty
reports  relating to Nokia's  sales of 2G and 2.5G covered  products,  Nokia has
violated the terms of its Patent  License  Agreement and Master  Agreement  with
InterDigital as well as violated the terms of the Award. On December 28, 2005, a
U.S.  District  Judge of the  United  States  District  Court  for the  Southern
District of New York confirmed the Award in its entirety. Nokia is appealing the
decision of the District Judge.

As a result of Nokia's  failure to comply  with the terms of the Patent  License
Agreement,  Master Agreement and Award,  InterDigital has requested  arbitration
seeking an order  setting  forth the precise  dollar  amounts  payable under the
Patent License Agreement,  Master Agreement,  and Award,  including interest, as
well as  requiring  Nokia to pay those  amounts to  InterDigital,  and  awarding
InterDigital reimbursement of its attorneys' fees and costs.

In  addition,  InterDigital's  request for  arbitration  seeks an interim  order
requiring Nokia to make partial payment based on sales information  disclosed in
the prior arbitration.  InterDigital also seeks an interim order requiring Nokia
to disclose all information  needed to determine the precise dollar amounts owed
to InterDigital under the Patent License Agreement and the Award.

This  arbitration  request is a further step in the dispute  resolution  process
that,  as  previously  reported  in a Form  8-K  filed  on  December  29,  2005,
InterDigital initiated in accordance with the terms of its agreements with Nokia
to accelerate the resolution of any and all unresolved  issues that may impact a
determination  of  amounts to be paid  under the  Award.  The Award and  related
arbitration are further described in our Form 10-K filed March 14, 2006.

The parties continue to pursue a mutually agreeable  resolution of this dispute.
Absent such resolution,  InterDigital  will continue to seek final resolution of
the dispute through the initiated arbitration and other legal processes.
