Google LLC v. Sonos, Inc., 2022 FC 1116

Justice Zinn - 2022-08-15

Read full decision. Automatically generated summary:

The Plaintiff, Google, is suing the Defendant, Sonos, for infringement of Claim 7 of Canadian Patent No. 2,545,150 entitled “Method and Apparatus for Adaptive Echo and Noise Control”. Sonos is counterclaiming alleging that Claim 7 of the 150 Patent is invalid as it is obvious and not inventive. ... In brief, I find that the Sonos Devices are not “configured to adaptively determine an order of echo cancellation and noise suppression based on an amount of noise in the received signal to generate a desired signal” and therefore do not infringe Claim 7. ... In any event, like Justice Kane in Teva, I find, given the difficulty in locating the 871 Patent, that the POSITA would not have been led directly and without difficulty to combine these references. For these reasons, I reject the Sonos submission that the 150 Patent was obvious based on any combination involving the 871 Patent. The Counterclaim must be dismissed.
