Christopher Guerreiro practises intellectual property dispute resolution and litigation, with an emphasis on patents and issues affecting the life sciences, healthcare, and other high-technology industries.

Mr. Guerreiro has spent much of his career working with innovative pharmaceutical companies. As a litigator and advisor, he focusses on developing dispute-resolution strategies that align with the unique interests and business objectives of clients in this space—whether through litigation or a negotiated outcome.

Mr. Guerreiro has particular experience with complex pharmaceutical and medical-device patent disputes. He has advised in a range of patent enforcement and defence proceedings before Canada's Federal Courts. Among them, Mr. Guerreiro was counsel on the first four actions brought under section 6 of the new Patented Medicines (Notice of Compliance) Regulations. His patent litigation work has touched on infringement, impeachment, and damages issues; a range of therapeutic areas; and both small-molecule and biologic products. Work in this space has often involved multi-jurisdictional coordination and management of out-of-court resolutions.

Mr. Guerreiro also advises on other contentious issues arising under the Patent Act, including patent-listing eligibility and issues concerning the Patented Medicine Prices Review Board (PMPRB). Mr. Guerreiro's work in this area has focussed on ongoing changes to the Canadian pharmaceutical price regime.
