Koss Sues a Slew of Wireless Headphone Makers

Koss Corporation has rebooted its sole litigation campaign, dormant since March 2017, with five new Western District of Texas complaints, one filed against each of Apple (6:20-cv-00665), Bose (6:20-cv-00661), PEAG (d/b/a JLAB Audio) (6:20-cv-00662), Plantronics (Polycom) (6:20-cv-00663), and Skullcandy (6:20-cv-00664). The plaintiff asserts six patents (in overlapping sets), new to litigation, broadly directed to wireless communication between devices. The defendants are accused of infringement through the provision of wireless devices, including wireless earphones, headphones, speakers, and smart watches.
