Under new ownership, SoundStreak Texas LLC did not waste time expanding its sole litigation campaign after reviving it with a late-August case against Yamaha. This past week, the NPE, now a subsidiary of publicly traded Quest Patent Research Corporation (QPRC), added suits against Nikon (2:21-cv-00362), Olympus (2:21-cv-00361), Panasonic (2:21-cv-00360), and Sony (2:21-cv-00359). A single patent generally related to managing a recording session over a network is asserted against each defendant, targeting their respective provision of remote audio/video recording products.

Early August saw publicly traded Quest Patent Research Corporation (QPRC) acquire SoundStreak Texas LLC, including its portfolio of three streaming data patents, from inventor-controlled patent plaintiff SoundStreak, LLC. Weeks later, QPRC’s SoundStreak Texas appears to have revived its former corporate parent’s litigation against Yamaha—which was voluntarily dismissed without prejudice in 2018.
