Samsung sues LG Display over OLED patents

In the legal battle between the two display makers, Samsung claims that some of the OLED patents held by LG are invalid.

Samsung has filed a lawsuit against LG Display in an effort to convince the court that seven of LG's OLED displays don't hold water.

Filed with an intellectual property tribunal in Korea, the suit is seeking to invalidate LG's patents on the grounds that they "lack innovation," according to the Yonhap News agency.

This is just the latest salvo in the ongoing legal turmoil between the two companies.

In September, LG Display filed suit against Samsung , claiming violation of the seven (organic light-emitting diode) patents in question. The lawsuit alleges that Samsung violated the design of LG's OLED panels, driver circuitry, and device design, according to Wall Street Journal.

In its suit, LG has been seeking an unspecified amount in damages and a permanent injunction of five infringing products, including the Galaxy S3 phone, the Galaxy Tab 7.7 tablet, and the Galaxy Note "phablet."

Earlier this year, 11 current and former Samsung Mobile employees at Samsung Mobile were arrested on charges that they allegedly stole and leaked details to LG about a Samsung AMOLED TV.

Six of LG's own workers were also involved in the theft of Samsung's OLED technology in 2010 and 2011.

Both headquartered in Korea, LG and Samsung are top manufacturers and competitors in the AMOLED (active-matrix organic light-emitting diode) display market. Such displays are thinner, brighter, and lighter than conventional LCD displays.

CNET contacted both Samsung and LG Display for comment and will update the story if we get any information.
