LG Electronics Confident It Will Prevail In MPT's Patent Case Appeal

Published on:

LG Electronics has expressed confidence that the U.S. Court of Appeals will affirm the judgments of the trial court in LG's favor in a three year intellectual property case involving mobile phones.

Despite losing to LG twice in U.S. District Court for the Southern District of California, the Multimedia Patent Trust (MPT) filed a notice of appeal on Aug. 30, 2013, attempting to challenge the court's rulings confirming that LG products do not infringe MPT's patents.

On the heels of a December 2012 jury decision that LG mobile phones do not infringe MPT's patents, the district court granted LG's motion for summary judgment in a second case in August 2013, holding that MPT was estopped from pursuing its claims further against LG based on its actions in the first case.

MPT filed the first lawsuit against LG in December 2010, alleging infringement of U.S. Patent No. 5,136,377 and U.S. Patent No. 5,227,878 related to video compression technology. LG vigorously defended its products against MPT's claims and in December 2012, following a 10-day trial, the jury determined that LG did not infringe these patents.

In the second lawsuit, filed in November 2012, MPT continued its litigation against LG by trying to assert the same non-infringing patents against additional LG products.

The court entered final judgment in both cases on Aug. 1, 2013.

In a statement, the company said, "LG Electronics is disappointed that MPT is still pursuing this meritless action against LG. We have always believed that MPT's patents simply do not apply to LG products. After a jury verdict and summary judgments in LG's favor, it is time for this lengthy litigation to come to an end."
