U.S. PTO Issues Final Decisions in Favor of LG Electronics in Four IPR Proceedings

February 2, 2017

On January 25 and February 2, 2017, the U.S. PTO issued final decisions in favor of LG Electronics (“LG”) in four inter partes review (IPR) proceedings challenging claims of four optical disk driver related patents owned by Toshiba Samsung Storage Technology Korea Corporation (“TSST-K”) and asserted against LG in the District of Delaware.

TSST-K sued LG in the District of Delaware on August 6, 2015, alleging  that LG infringed U.S. Patent Nos. 6,721,110, 6,785,065, RE43,106, and 7,367,037.  In response, LG filed petitions for IPR asserting that all the claims brought by TSST-K in the related litigation were unpatentable. Over the last week, the U.S. PTO issued its rulings in favor of LG in all 4 IPR proceedings, finding all the challenged patent claims unpatentable on every ground asserted by LG.

The IPR’s are IPR2015-01642, IPR2015-01644, IPR 2015-01653 and IPR 2015-01659.

LG Electronics was represented by Steven Lieberman, Brian Tollefson, Michael Battaglia, Soumya Panda, Michael Jones, and Eric Blatt of Rothwell Figg Ernst & Manbeck, P.C.
