Fujitsu files plasma display patent suits against Samsung

Alleges IP infringement

Fujitsu has alleged Samsung of plagiarising its plasma display intellectual property, and yesterday back up the allegation with lawsuits in Japan and the US.

In a complaint submitted to the Tokyo District Court and the US Federal District Court of Los Angeles, the Japanese company claims Samsung's PDPs infringe on a patent it holds in Japan, number 2,845,183. The US suit alleges violation of ten other patents.

Fujitsu claims it attempted to negotiate a settlement with Samsung, but talks broke down without a deal being reached. Consequently, the plaintiff wants the courts to block Samsung PDPs from being imported and sold in their respective countries and to order the payment of compensation for the alleged infringement.

"Fujitsu has invested over 30 years and very significant resources in developing commercially viable PDP technology," said Masanobu Katoh, group president of Fujitsu's Intellectual Property Group, in a statement. "We cannot permit others to exploit these valuable inventions without appropriate compensation."

Samsung has yet to respond to the allegations. ®
