Osler has an active intellectual property litigation practice encompassing all aspects of this field, including:

  • Anti-piracy programs;
  • Trade-mark registrability;
  • Trade-mark oppositions and expungements;
  • Passing off/gray marketing;
  • Patent infringement/impeachment;
  • Copyright/industrial design infringement;
  • Misleading/comparative advertising;
  • Trade secret protection.

We appear routinely before the Federal Court of Canada and Superior Courts of the provinces. In Toronto, our intellectual property litigation practice is carried out by a number of litigators who have a general commercial litigation background with a particular emphasis on intellectual property matters, backed by the Intellectual Property Department of lawyers, patent agents and trade-mark agents. In Ottawa, this practice is carried out by intellectual property specialists. Thus, we can deploy the most effective and efficient legal team to respond to each client’s particular needs. We offer expertise in protecting, exploiting and enforcing intellectual property rights and bring a business-oriented approach that combines creative solutions with sound legal advice.
