In Pharmascience v. Janssen Inc., the Supreme Court of Canada reaffirmed that methods of medical treatment remain unpatentable subject matter under the Patent Act because they are directed to the professional skill and judgment of healthcare practitioners. At the same time, the Court upheld the patentability of the dosing regimen claims at issue, clarifying that not all therapeutic or treatment-related claims constitute unpatentable methods of medical treatment. The decision provides important guidance on assessing patent eligibility for pharmaceutical and life sciences innovations in Canada.
