ViiV Healthcare ULC v Teva Canada Limited, 2015 FCA 93 - The FCA confirmed that paragraph 4(2)(a) of the Patented Medicines (Notice of Compliance Regulations) requires that a patent listed on the register requires an “exacting threshold of specificity” between what is claimed in the patent and what has been approved in the Notice of Compliance. However, proposed amendments to the PM(NOC) Regulations would reverse this holding.
