Canada’s Premier IP Litigation Firm

We are internationally ranked and have been lead counsel in many precedent-setting decisions, including at the Supreme Court of Canada. We have twice won a prestigious patent case of the year award and won the impact case of the year in 2023.

We are trial lawyers with extensive experience in all areas of patent, trademark, and copyright litigation. Our unrivaled track record of successfully representing pharmaceutical manufacturers in patent litigation under both the Patent Act and the Patented Medicines (Notice of Compliance) Regulations is built on a history of winning cases that other counsel have previously lost.

We’ve taken on some of the most challenging cases, including successfully addressing numerous compound, formulation, and use patents on blockbuster drugs. Our lawyers have prevailed in a number of pivotal cases that continue to shape Canadian patent law, including defining the requirements of written description, clarifying the meaning of “inventive concept”, and prevailing on the only s. 53 invalidity defense (misleading statements in a patent) in the last 40 years.
