Company to Host Conference Call at 2:00 PM ET to Discuss Recent ITC Determination

KING OF PRUSSIA, Pa.--(BUSINESS WIRE)-- InterDigital, Inc. (NASDAQ:IDCC) today announced financial guidance for third quarter 2009. InterDigital^(R) expects third quarter 2009 revenue to be in the range of approximately $73.5 million to $75.5 million. This range does not include any potential impact of any new agreements that may be signed during third quarter 2009 or the potential impact of any additional royalties identified in audits regularly conducted by the company.

"Third quarter 2009 reflects solid 3G sales by our patent licensees," commented Scott McQuilkin, InterDigital's Chief Financial Officer. "In addition, based on the sales reports it appears that the declines in overall handset sales have stabilized in second quarter 2009 and indeed some of our key licensees have reported increases in sales."

As a follow up to the company's press release on Friday, August 14, 2009 regarding the Initial Determination (ID) in the company's ITC case involving Nokia, the company will host a conference call today at 2:00 p.m. to discuss the determination and the appeal process.
