Google and Sonos are now fighting over voice assistant patents

Google has sued Sonos, alleging that its new voice assistant violates seven patents related to its own Google Assistant technology, CNET has reported. It's the latest salvo in a long-running smart speaker battle between the companies, with each suing and countersuing the other following a period when they worked together. "[Sonos has] started an aggressive and misleading campaign against our products, at the expense of our shared customers," a Google spokesperson said in a statement. Sonos' Voice Control assistant arrived in June, letting users give commands with the phrase "Hey Sonos," much like Amazon's Alexa or Google Assistant. In the complaint, Google said it "worked for years with Sonos engineers on the implementation of voice recognition and voice-activated devices control in Sonos products... even providing its Google Assistant software to Sonos for many years."
