Milwaukee, WI based Koss Corporation (NASDAQ:KOSS) last month launched a significant litigation effort against several major industry brands in an effort to assert and protect its IP portfolio rights. On July 22, 2020, Koss filed lawsuits against each of Apple, Inc., Bose Corporation, PEAG LLC dba JLAB Audio, Plantronics, Inc., and Skullcandy, Inc. Each of these auspicious brands, Koss says, are infringing on their patents covering wireless headphones and speakers.
