LG Electronics/Innotek and Lexington Luminance Lock Horns Before the PTAB and in District Court
A February 2015 Federal Circuit opinion reversing a Massachusetts district court’s construction of several claim terms in the lone patent (6,936,851) brought the campaign of Lexington Luminance LLC back to life. Litigation resumed in separate cases brought against Amazon and Google, leading to recent dismissal in each case, and so far in 2016, the NPE has added cases against three more defendants: Samsung (2:16-cv-00169, filed in February 2016), TCL (1:16-cv-11458, filed in July 2016), and LG Electronics and LG Innotek (1:16-cv-12175, filed in October 2016). The ‘851 patent generally relates to improving the manufacture of light-emitting diodes (LEDs). Defendants’ mobile phones, tablet computers, televisions, and/or other electronic devices have been at issue throughout the campaign.

Semiconductor Patent Given New Life Asserted Against Samsung, as Cases Against Amazon and Google Have Ramped Back Up
Lexington Luminance LLC has filed another case in its light-emitting semiconductor devices campaign, this time against Samsung (2:16-cv-00169). The complaint asserts a single patent (6,936,851) against Samsung’s mobile phones, tablet computers, and other electronic devices, this time in the Eastern District of Texas, a shift away from the forum—District of Massachusetts—in which the campaign has had an extensive history up to this point.

Amazon Prevails in Semiconductor Patent Case
A Massachusetts district court has ruled in favor of Amazon in a suit initiated by Lexington Luminance. Lexington sued Amazon in November 2012 for alleged infringement of a patent related to the fabrication of semiconductor devices (6,936,851). The complaint accused Amazon’s e-reader devices and tablet computers, including the Kindle Fire, of infringing the ‘851 patent. Amazon’s answer included a counterclaim for a declaratory judgment of invalidity, and in August 2013, Amazon filed a motion for judgment on the pleadings. Following same-day hearings on claim constructions and Amazon’s motion, the court found claim 1 of ‘851 to be indefinite. This week Judge Denise Casper entered a judgment in Amazon’s favor and dismissed Lexington’s complaint.
