Strength in intellectual property

Our top-ranked IP team is renowned for its diverse strengths, including IP litigation and patent disputes. We have acted as counsel in complex litigation in every field of intellectual property and before every level of the Canadian courts, and have coordinated and managed prosecution and litigation strategies through multiple jurisdictions. Our international reputation for excellence in Canadian IP patent litigation has been built on our winning litigation record, representing some of the world’s largest generic pharmaceutical, technology, biotech, life sciences, electronics, energy, consumer products and many other international and domestic innovators.

We have extensive experience in drafting, filing, prosecuting and maintaining patent and industrial design applications in Canada and the United States, including for Canadian and multinational companies in medical devices, electronics, consumer products, chemistry, biotechnology, pharmaceuticals, sports, food services and other sectors. We also supervise the filing and prosecution of patent applications outside North America on behalf of clients through our network of foreign associate law firms. The Osler IP team also serves a growing and robust international practice, representing Canadian patent interests of foreign companies.

Osler’s integrated team of professionals is involved in preparing numerous patent infringement and validity opinions, drafting patents and advising on the exploitation of obtaining IP rights with a coordinated worldwide strategy consistent with clients’ commercial business.
