                                Explanatory Note
                                ----------------

     We are  filing  this  Amendment  No. 1 to our  Current  Report  on Form 8-K
originally  filed with the  Securities  and Exchange  Commission on September 8,
2005, to amend the Item Number from Item 1.01 to Item 8.01 and certain  portions
of the original  text of the Form 8-K.  There have been no changes to the patent
license agreement referred to below.

Item 8.01.        Other Events.

     On  September 1, 2005,  InterDigital  Communications  Corporation's  patent
holding subsidiaries  (collectively,  "InterDigital")  entered into a worldwide,
non-transferable,  non-exclusive, patent license agreement with Kyocera Wireless
Corp.,  and  its  parent  corporation,   Kyocera   Corporation,   (collectively,
"Kyocera").  The  five-year  3G  patent  license  agreement  covers  the sale of
terminal  units  compliant  with  cdma2000(R)   technology  and  its  extensions
commencing July 1, 2004.  InterDigital  Technology  Corporation,  a wholly-owned
subsidiary of InterDigital Communications  Corporation,  and Kyocera Corporation
are also parties to a TDMA-technology patent license agreement, which remains in
place.

     Under  the terms of the new  patent  license  agreement  and  subject  to a
Kyocera  option to convert the license to a  royalty-bearing  basis,  Kyocera is
obligated  to pay  InterDigital  a  license  fee of $50  million,  which  covers
licensed  product  sales up to a  specified  threshold  dollar  amount.  The $50
million fee is payable in four installments, including an initial payment of $20
million which we received in third quarter 2005.  Subject to Kyocera's  right to
exercise its option,  Kyocera is obligated to pay three  additional  $10 million
installments  due no later  than the third  quarters  of 2006,  2007,  and 2008,
respectively.

     cdma2000(R) is a registered  trademark of the  Telecommunications  Industry
Association (TIA-USA).
