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.
Koss pleads that it was formed as a "television rental
company in Milwaukee, Wisconsin" in 1953, with its founder
John C. Koss inventing "the world's first SP/3 Stereophone
as part of a "private listening system" that would enable
the wearer to listen to a phonograph without disturbing others in
the vicinity".
