Supreme Court of Canada denies Merck leave to appeal from decision upholding strict interpretation of patent listing deadline

Merck sought leave to appeal a decision of the Federal Court of Appeal (2021 FCA 224) affirming a Federal Court decision upholding Health Canada’s refusal to add a patent relating to a formulation of Merck’s KEYTRUDA, a biologic drug containing pembrolizumab, to the Patent Register.
