This endorsement addresses three complex motions brought by the plaintiff Apotex Inc. and the defendants Sanofi-Aventis, Sanofi-Aventis Deutschland GmbH, Sanofi-Aventis Canada Inc. (collectively "Sanofi"), and Schering Corporation ("Schering"), seeking to compel answers to undertakings and refusals in a long-running pharmaceutical patent litigation.
The motions involved approximately 480 questions, later narrowed to 101.
The Master applied principles of relevance and proportionality under the Rules of Civil Procedure, emphasizing the balance between extensive discovery requests and the significant damages claimed.
Many broad requests for documents and information were denied as disproportionate or overbroad, while narrower, more targeted requests were granted.
The court also addressed issues of solicitor-client privilege and the obligation to state legal positions.
