The agreement with Ericsson follows a licensing deal reached earlier with Nokia for DTL, which owns a key patent for modern cellular technology.

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.

GPCI represents Digital Technologies Licensing LLC in the licensing and enforcement of the DTL Patent. DTL brought patent infringement suits against Verizon Wireless, Cingular Wireless, T-Mobile and Sprint and other companies. Ericsson was not a party to any of these lawsuits.

"We are very pleased to extend a non-exclusive license to Ericsson," said Alexander Poltorak, GPCI's Chairman and CEO.
