Hybrid Audio LLC has added another round of lawsuits to its sole litigation campaign, accusing Acer (1:17-cv-10113), Bose (1:17-cv-10116), Garmin (1:17-cv-10118), Lenovo (1:17-cv-10120), and Logitech (1:17-cv-10122) of infringing an expired, reissued patent (RE40,281) generally related to digital signal processing. The plaintiff alleges that the ‘281 patent is essential to the MP3 audio standard and accuses the new defendants of infringement through the provision of devices utilizing that format. These latest suits follow three cases filed on January 6 against Delphi Automotive (1:17-cv-10030), Sharp (1:17-cv-10026), and VOXX Electronics (1:17-cv-10031), each of which remains in initial pleadings.
