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.
