Pioneer Sues Samsung Over Plasma Patents

September 27, 2006
Pioneer has filed suit in an American court against Samsung for what the Japanese firm contends are patent violations of its plasma HD/SD by the South Korea manufacturer. Samsung, the world's largest plasma display maker, reportedly will file a countersuit in the near future.

Pioneer's legal action this week is hardly the first of its kind affecting Pioneer and several of its competitors, according to Reuters. There have been a number of intellectual property suits among Japanese companies filed against other Asian firms, although this is reportedly the first time Pioneer has initiated litigation for alleged infringement of a specific patent.

Besides Pioneer, Samsung also has been involved in patent disagreements with Matsushita Electric Industrial (Panasonic brand) and Fujitsu. Samsung has been holding talks with Pioneer for more than a year and a half about possible licensing agreements, with no success. (LG Electronics and Matsushita signed cross-licensing agreements with Pioneer in early 2005.)

The disputes center on a pair of patents (re: electrode configuration and an unspecified production step) that the firm said affects overall screen quality and brightness.
