Sonos is fighting a war to stay relevant

For Sonos, 2020 began in dramatic fashion. While the tech world was focused on CES, the company made a splash by suing Google for allegedly infringing five of its wireless speaker patents. Sonos said this was just a small portion of Google's overall infractions, noting that both Amazon and Google likely violated about 100 patents each. Google counter-sued in June, and Sonos filed more charges in September. Sonos is well within its rights to defend its patent portfolio -- and the company has been working on wireless music-streaming tech for longer than just about anyone, so it's entirely possible its claims have merit.
