This article explores how courts continue to apply and refine the &ldquo;some basis in fact&rdquo; test for certifying common issues in class actions. Recent decisions illustrate that while expert evidence is not always required, plaintiffs must provide sufficient admissible evidence to support both the existence of common issues and their class-wide resolution. The rulings reinforce certification as a meaningful screening tool and provide guidance on evidentiary expectations going forward.

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.
