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
