General Patent Corporation (GPC) subsidiary LaserDynamics USA, LLC has added Advanced Media and Ritek (1:16-cv-06621), CD Video Manufacturing (1:16-cv-06619), and Media Masters and Moser Baer India (1:16-cv-06626) to its sole litigation campaign, asserting three patents (6,426,927; 6,529,469; 7,116,629) generally related to recordable optical discs. Ritek is accused of infringing the ‘469 patent alone, while the others are targeted over all three patents. The companies are alleged to infringe by making and selling single- and dual-layer optical DVD discs in multiple formats, including DVD-R, DVD+R, DVD-RW, and DVD+RW.

After closing its previous litigation, LaserDynamics, LLC filed two new suits to continue its campaign. It asserted a single patent against Boss Audio, GPX, and Pyle Audio (5,587,981) and asserted two other patents against Cinram Group (6,426,927, 6,529,469). The three asserted patents relate to reading and writing data on an optical disk. LaserDynamics’s campaign asserts patents related to optical disk technology, but it has not previously asserted the ‘927 or ‘469 patents. Similar to previous suits, the case against Boss Audio, GPX, and Pyle Audio accuses their CD, DVD, and Blue-ray players of infringing the asserted patent. The suit against Cinram accuses optical disks made by the company of infringement. LaserDynamics began filing litigation in December 2013 and filed additional suits in March and July 2014. All of those suits were dismissed within a year of filing.

LaserDynamics LLC, a subsidiary of General Patent Corporation, doubled the size of its campaign when it filed suit against Target, along with codefendants Boombang Inc., on the same day it sued Craig Electronics, Inc. The entity has asserted a single suit in its two previous litigations and is asserting the same patent in these new suits (5,587,981). The patent-in-suit relates to reading an optical disk and in these latest suits DVD players made or sold by the defendants are accused of infringement. The ‘981 patent was previously asserted by inventor Yatsuo Kamatani and then by former operating company LaserDynamics Inc. It was subject to ex parte reexamination and in 2009 the USPTO cancelled claim 1. LaserDynamics LLC received the patent from an assignment in December 2013 and filed its first assertion litigation that month. 7/9, Southern District of New York, 1:14cv05112, 1:14cv05113
