May 4, 2010 - LG Electronics not only lost the patent infringement lawsuit it filed against AU Optronices, but was even found to be infringing AU's patents itself.
A division of LG, LG Display, filed a lawsuit in December 2006 alleging that AU infringed four of its patents related to LCD displays. AU denied the claims and filed its own lawsuit against LG, alleging that LG infringed four of AU's patents related to LCD optimization.
A U.S. District Court judge in Delaware first found LG guilty of infringement of all four AU patents in February; on April 29, the same court found that AU was not guilty of patent infringement on all of LG's charges.
