Nortel sues Kyocera, alleges patent infringement

Nortel Networks has sued Kyocera Wireless over alleged infringement of four Nortel patents on CDMA (Code-Division Multiple Access) technology, according to Nortel spokesman David Chamberlin.

The telecommunications equipment giant alleged in the suit, filed January 4 in the US District Court for the Northern District of Texas, in Dallas, that Kyocera Wireless used the Nortel technology in its handsets.

The legal action follows a long period of unsuccessful discussions over licensing, according to Chamberlin. He declined to discuss the patents in detail.

Kyocera Wireless officials did not return calls seeking comment. Parent company Kyocera International, the North American unit of Japan-based Kyocera, had not received a notification of the suit, according to Jay Scovie, Kyocera International spokesman.
