ADVERTISEMENTS

The following press release appeared today, April 16, 2008, on Business Wire:

General Patent Corporation International (GPCI), a leading patent licensing and enforcement firm, announced today on behalf of its client, Digital Technology Licensing LLC (DTL), that it has licensed a key cell phone patent to LG Electronics, Inc.

DTL owns U.S. Patent No. 5,051,799 titled ?Digital Output Transducer? (Patent), which 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.

GPCI represents DTL in the licensing and enforcement of the Patent. DTL brought patent infringement suits against Verizon Wireless, Cingular Wireless (now know as AT&T Mobility), T-Mobile, Sprint and other companies. LG was not a party to any of these lawsuits. Previously, DTL announced that Nokia, Ericsson and Samsung had licensed its Patent, and that the law suits against Cingular Wireless and AT&T Mobility had been settled with AT&T Mobility taking a license under the Patent.
