Motorola, General Patent Settle Patent Infringement Suit Involving Digital Output Transducer

Patented Technology Assures Backward Compatibility of Cell Phone Handsets, Base Stations and Affects Bluetooth Headsets

Suffern, NY - August 26, 2008 - General Patent Corporation (GPC), a leading patent licensing and enforcement firm, today announced that a settlement has been reached in a patent infringement lawsuit between its client, Digital Technology Licensing (DTL) and Motorola, Inc.

The "Digital Output Transducer" (Patent) at the center of the case is owned by DTL. The transducer is an essential patent for Adaptive Multi-Rate (AMR) codec and other cellular communication standards. The patented technology is also used to assure backward compatibility of cell phone handsets and base stations. Other applications of the patented technology include Bluetooth headsets.

"The settlement with Motorola follows DTL licensing and settlement deals with Nokia, Samsung, Cingular, Ericsson and LG," said Alexander Poltorak, GPC's Chairman & CEO. "We are very pleased to have resolved this lawsuit on amicable terms and look forward to licensing the rest of the defendants in the remaining lawsuits."

DTL has also brought patent infringement suits against Verizon Wireless, T-Mobile and Sprint.

A declaratory judgment lawsuit was filed by Motorola against DTL in November 2007 in the Southern District of New York (07 CV 10436) for the non-infringement of DTL's U.S. Patent No. 5,051,799 ('799 Patent) by Motorola's digital cellular handsets and equipment. DTL subsequently charged Motorola with infringement of the '799 patent.

DTL is represented by the law firm of Lerner, David, Littenberg, Krumholz & Mentlik, LLP (LDLKM).

"The growing number of settlements and licensees is overwhelming evidence of the industry's acceptance of DTL's patent as a de facto standard," said Stephen Roth of LDLKM, the chief litigation counsel in this case.
