Alphabet (Google) has returned fire against Sonos (3:20-cv-03845), accusing the company in a new Northern District of California case of infringing five patents through the provision of the “Sonos One, One SL, Play:1, Play:3, Play:5, Playbar, Playbase, Beam, Move, Connect:Amp, Amp, Connect, Port, and Sub products”. In January of this year, Sonos sued Google in the Central District of California and before the International Trade Commission (ITC), asserting five patents of its own in complaints targeting various products that support multi-room audio, including Chromecast, Google Home, and Nest hardware; Google apps related to media and home automation; and Google devices preinstalled with those apps.
