Whether the issue is protecting copyrights or defending them from infringement claims, our copyright group draws on decades of experience in addressing complex copyright issues across numerous industries for both domestic and international clients.

BLG’s IP litigation group has experience in all aspects of IP disputes, including actions respecting infringement and validity of patents, trademarks, industrial designs, copyright and trade secrets and confidential information issues. Our IP litigators bring together the best of both worlds – trial experience and the ability to communicate highly technical and legal issues to administrative boards and judges, and the technical and scientific prowess to field all IP issues.


BLG also has extensive experience with the full range of complex technology-driven agreements relating to both in and out-licensing and technology transfer opportunities in the commercial, academic, non-profit and government sectors across Canada and globally. Additionally, our group has assisted clients in developing and exploiting their IP portfolios by negotiating and drafting licensing agreements for both domestic and international licensing and technology transfer transactions.
