Damages denied where prohibition proceeding was dismissed for mootness after failing on the merits.
The plaintiff, a generic drug manufacturer, brought an action for damages against the defendants under s. 8 of the Patented Medicines (Notice of Compliance) Regulations for delayed market entry of its generic drug.
The plaintiff argued it was entitled to damages because the defendants' prohibition proceeding was dismissed for mootness after the underlying patent was invalidated in a separate proceeding.
The court dismissed the claim, finding that the plaintiff's allegations in the prohibition proceeding had failed on the merits, and s. 8 does not provide redress where the innovator prevailed on the merits but the patent was later invalidated by a third party.
The court also found that, even if liability existed, the plaintiff would not have entered the market any sooner in the hypothetical world due to its risk-averse nature.
