The Canadian Intellectual Property Office (CIPO) has materially changed how examiners are instructed to apply the law on patentable subject matter. In March 2026, CIPO replaced its November 2020 practice notice on computer-implemented inventions, medical diagnostic methods, and medical uses. The 2026 notice represents an important development for current Canadian prosecution practice.
