The Canadian Intellectual Property Office (CIPO) has proposed amendments to the Manual of Patent Office Practice (MOPOP) relating to patentable subject-matter. MOPOP is intended to be a comprehensive guide to CIPO's patent practices. The proposed amendments are intended to reflect the evolution in Canadian patent law and examination practices for computer-implemented inventions following two landmark decisions: Canada (Attorney General) v. Benjamin Moore & Co. 2023 FCA 168 (Benjamin Moore) and Choueifaty v. Canada (Attorney General) 2020 FC 837 (Choueifaty). Below we outline the historical context that led to this update and summarize the proposed amendments.
