LG Countersues Hitachi Over Patent Violations

Both companies have been trying to reach a settlement regarding patents related to plasma display technologies since 2005.

SEOUL, South Korea (AP) - South Korea's LG Electronics Inc. said Monday it will file a counter-lawsuit against Hitachi Ltd. claiming the Japanese company infringed on patents related to LG's plasma displays.
 
The patent infringement and damage compensation lawsuit will be filed in a Texas district court later Monday, LG Electronics said in a statement.
 
Hitachi officials weren't immediately available for comment.
 
LG said its complaint alleges the U.S. unit of Hitachi and Fujitsu Hitachi Plasma Display Ltd., a joint venture with Japan's Fujitsu Ltd., infringed on seven LG patents.
 
The South Korean company is a major manufacturer of plasma display panels used in flat screen televisions.
 
LG's lawsuit follows a similar suit that Hitachi filed against LG Electronics and its U.S. unit in the same court.
 
Hitachi filed the suit April 23, saying LG has infringed on seven Hitachi patents, also related to plasma display panels. Hitachi sought monetary compensation and a permanent injunction prohibiting the sale of LG's plasma display products in the U.S.
 
LG and Hitachi have been trying to reach a settlement regarding patents related to plasma display technologies since 2005.
