General Patent Corporation Acts as Licensing Agent

Suffern, NY - March 10, 2008 - General Patent Corporation (GPC), a leading patent licensing and enforcement firm, announced today on behalf of its client, Digital Technology Licensing LLC (DTL), that it has settled its patent infringement lawsuits against Cingular Wireless and AT&T Mobility.

The lawsuit against Cingular Wireless was filed in April 2006 in the Eastern District of Texas (2:06 CV 156) for the infringement of DTL's U.S. Patent No. 5,051,799 ('799 Patent) by GSM cellular telephone systems and services. A second lawsuit was filed against AT&T Mobility (formerly known as Cingular Wireless) in November of 2007 in the District of New Jersey for the infringement of the '799 Patent by UMTS cellular services. Both lawsuits have been settled, and AT&T Mobility has licensed the '799 Patent.

"The settlement with AT&T Mobility and Cingular follows licensing deals with Nokia, Ericson and Samsung," said Alexander Poltorak, GPC's Chairman & CEO. He continued, "This latest agreement is with the largest cell phone service provider in the US."

DTL owns U.S. Patent No. 5,051,799 titled "Digital Output Transducer."
