In July of 2017, the Federal Court of Canada granted the largest damages award in Canadian history for patent infringement on the basis of an accounting of profits in Dow Chemical Company v Nova Chemical Corporation, 2017 FC 637, as previously reported by the E-TIPS® Newsletter here. On September 15, 2020, the Federal Court of Appeal of Canada (the Court) upheld that award and took the opportunity to identify and explain the principles that underlie an accounting of profits as a remedy for patent infringement (2020 FCA 141).
The Court underscored the principle that the application of any of the remedies for infringement provided by the Patent Act must be consistent with the bargain it creates between inventors and the public. In cases where an infringer’s gain is greater than the patentee’s loss, an accounting of profits is the appropriate remedy to uphold the Patent Act’s bargain and provide a necessary disincentive to infringement.
The Court stated that an accounting of profits disgorges the benefit obtained by the infringement – no more and no less. Therefore, an accounting of profits must strip the infringer of all the benefits of the infringement but it is not intended to be punitive. The Court held that when calculated according to proper principles, the size of the award is irrelevant. More specifically, the Court concluded that the following principles must be applied:
The Court’s analysis provides clarity for the valuation of accounting of profits to help patentees decide between either compensation for its actual damages suffered or the infringer’s profits.
