InterDigital Announces Financial Guidance for Third Quarter 2009

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® 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.
