The validity of AstraZeneca's NEXIUM patent has finally been decided by the Supreme Court of Canada, with any doubt about the court's intent resolved by its dismissal of Apotex's motion to raise new grounds of patent invalidity. The court also held that AstraZeneca was entitled to a declaration of infringement and ordered the quantification of AstraZeneca's damages or Apotex's profits.
Two recent decisions addressed procedure under the 2017 amendments to the Patented Medicines (Notice of Compliance) Regulations. In the first case, Prothonotary Aylen ruled that the court lacked jurisdiction to consider a motion under Section 5(3.7) of the regulations to vary confidentiality rules imposed by a party that has served a notice of allegation under Section 5(3.5). In the second case, Aylen dismissed Pfizer's motion to dismiss, adjourn or delay a motion filed by Amgen under Section 6.08.
Health Canada recently issued the first certificates of supplementary protection (CSPs) against three approvals. In addition, on 1 April 2018 the CSP application fee was increased to C$9,192.
The Federal Court of Appeal recently dismissed Teva's appeal regarding the quantification of damages for its infringement of Janssen's patent for levofloxacin (Levaquin). The Federal Court of Appeal rejected Teva's arguments, finding that the Federal Court had not erred in constructing the hypothetical world and that its factual findings were supported by evidence. On 26 March 2018 Teva applied to the Supreme Court for leave to appeal.
Servier and its related company ADIR were recently successful in another chapter of the patent litigation concerning perindopril when the Federal Court again dismissed the non-infringing alternative defence of Apotex Inc and Apotex Pharmachem Inc (collectively, Apotex). The court found that Apotex would not have called on foreign third parties to manufacture perindopril to supply its affiliates in the United Kingdom and Australia and thus reaffirmed the quantum of profits from its original judgment.
