A team of outstanding litigators is one of the highlights of Osler’s top-ranked Intellectual Property Group. Over the years, they have built an enviable reputation for excellence in Canadian IP litigation based on their record of success representing domestic and international innovators, and in particular, clients from the biotechnology, pharmaceutical and technology industries.

Osler’s expert IP litigators have deep experience protecting, exploiting and enforcing intellectual property rights and bring a business-oriented approach that combines creative solutions with sound legal advice. Our practice encompasses all aspects of IP litigation, including

  • patent infringement/impeachment
  • copyright infringement
  • industrial design infringement
  • trade-mark registrability, oppositions and expungements
  • anti-piracy programs
  • trade secret protection

Osler lawyers regularly appear before the Federal Court of Canada and Superior Courts of the provinces. In Toronto, our intellectual property litigators have a general commercial litigation background with a particular emphasis on intellectual property matters, backed by our Intellectual Property Group of lawyers, patent agents and trade-mark agents. In Ottawa, this practice is carried out by intellectual property specialists.
