Selected leading cases are organized by selected topic. Case law may be applicable to more than one topic. Note that selected topics do not necessarily address all relevant topics and selected cases do not necessarily address all relevant issues per topic. Cases are selected to illustrate various legal concepts and are not intended as a substitute for competent legal advice from a Patent Lawyer or Patent Agent. An extensive public listing of case law, organized by topic may be found at the end of each chapter of the Canadian Manual of Patent Office Practice (MOPOP) or U.S. Manual of Patent Examination Procedures.
