US ITC supports LG in microprocessor patent case

LG Electronics has received a favourable final determination from the U.S. International Trade Commission (ITC) in a microprocessor patent infringement case. Technology Properties Ltd LLC (TPL) and affiliated companies filed a complaint in the ITC against LG and other respondents in July 2012, alleging infringement of U.S. Patent No. 5,809,336 related to variable speed system clocks in microprocessors.

LG maintained from the beginning that it does not violate any patent rights asserted by TPL and its co-complainants, and LG vigorously defended its products against TPL's claims during a seven-day trial in the ITC in June 2013.

After considering the evidence presented at trial, an ITC administrative law judge (ALJ) issued an initial determination in September 2013 in which he found no infringement by LG. Although TPL challenged the ALJ's initial determination, the ITC Commissioners issued their final determination confirming the ALJ's ruling of no infringement by LG.

Joosup Kim, VP, intellectual property center, LG, said, "LG Electronics has always believed that TPL's patent does not apply to LG products. We are pleased that the ITC's final determination vindicates LG's position."
