The Federal Court of Appeal in Google LLC v. Sonos Inc., 2024 FCA 44 dismissed Google’s appeal challenging the decision of the Federal Court that Sonos did not infringe Google’s patent (Canadian Patent No. 2,545,150), upholding the Federal Court’s decision (2022 FC 1116). The Google patent relates to a system for adaptive echo and noise control in electronic equipment – for example, smart speakers.
