Background

Earlier this week, the Federal Court of Canada publicly released Amgen Inc. v. Pfizer Canada ULC, 2020 FC 522, the first trial decision under the amended Patented Medicines (Notice of Compliance) Regulations ("PM(NOC) Regulations"). Prior to 2017, proceedings under Canada's drug patent linkage legislation, the PM(NOC) Regulations, proceeded by summary application with affidavit evidence and cross-examinations out of court.

Relevant to this case, under the Old Act, patent applications were not published until the patent was issued.
