Item 8.01.        Other Events.

As previously reported in InterDigital Communications Corporation's (the
Company) 2004 Form 10-K and Form 10-Q for the periods ended March 31, 2005 and
June 30, 2005, in March 2004, Tantivy Communications, Inc. (Tantivy), one of the
Company's wholly-owned subsidiaries, filed a lawsuit in the United States
District Court for the Eastern District of Texas (the Court) against Lucent
Technologies, Inc. (Lucent), a leading manufacturer of cdma2000(R) equipment.
The case is based on Tantivy's assertions of infringement by Lucent of Tantivy
patents issued in the United States. The lawsuit seeks damages for past
infringement and an injunction against future infringement, as well as interest,
costs, and attorneys' fees.

In May 2005, the Markman hearing (for claim construction) was held. On August
11, 2005 the Company received the Court's decision regarding the Markman
hearing. The Court's decision adopted many of Tantivy's proposed claims
constructions. The Company does not believe that the Court's claim constructions
limit in any material manner the relief that Tantivy seeks in the litigation.

The parties are currently in the discovery phase of the litigation. The Company
expects the trial to occur some time this fall. 

cdma2000(R) is a registered trademark of the Telecommunications Industry of 
America.
