Today, Sharp filed a patent infringement lawsuit against Samsung Electronics in the Seoul Central District Court in South Korea.
The complaint alleges that (1) liquid crystal display (LCD) modules manufactured and/or sold by Samsung in South Korea and (2) LCD TVs manufactured and/or sold by Samsung in South Korea that incorporate these LCD modules infringe upon three LCD-related Korean patents that are owned by Sharp.
In the complaint, Sharp requests that the Court award it compensatory damages and prohibit the manufacturing and sale of the infringing products in South Korea.
The three patents named in the lawsuit are Korean Patent Numbers 371,939, 740,570 and 776,988. These patents relate to LCD technologies that achieve high brightness and high-speed response, as well as a wide viewing angle by regulating and stabilizing the alignment of the LCD molecules.
On August 6, 2007, Sharp filed a patent infringement lawsuit against Samsung and its US subsidiaries Samsung Electronics America, Inc. (SEA) and Samsung Telecommunications America (STA) in the US. That lawsuit is now pending.
