In its surprising final verdict in the 2006-filed infringement lawsuit, US District Court for the District of Delaware Friday said that LG Display, the LGD-making unit of LG Electronics – which had filed the case against the Taiwanese AU Optronics (AUO) - failed to prove its claims that AUO had violated four patents pertaining to materials and processes used in making LCD panels.

Having vehemently refuted LG Display’s arguments, AUO had filed a counter-lawsuit against LG, citing LG’s patent-infringement of four of AOU patents including technology used for reducing glitches and increasing reliability and response time – largely related to LCD TVs and displays used in computers and mobile phones.

AUO had already won the counter-claim portion of the lawsuit in a court ruling announced on February 16.

In the 77-page final ruling in the LG-AOU lawsuit, Judge Joseph J. Farnan Jr. said: “The court concludes that AUO has established by preponderance of the evidence that LGD literally infringes the patents asserted by AUO in this action, and that LGD has not established by clear and convincing evidence that the asserted patents are invalid.”

With the final verdict going in its favor, AOU now intends seeking a US injunction against the import and sale of the LCD panels manufactured by the South Korea-based LG Display. Such a ban will essentially affect the consumers, as over 25 percent of the world’s LCD panel supply comes from LG.
