With over 725 lawyers, IP agents and other professionals, BLG serves businesses and institutions across all of their legal needs; from M&A and capital markets to major litigation, financing and trademark and patent registration.

BLG’s IP group offers trusted advice on the development, protection, commercial exploitation and use of intellectual property to a diverse client base that includes start-ups and national and multinational companies of all industry sectors. Our IP group works in a collaborative environment with a client-team approach which extends to our strong network of well-respected IP firms around the world to help clients to expand their businesses and protect IP assets outside Canada. This approach allows BLG to offer streamlined, cost-effective and tailored services to clients.


BLG’s patent group provides sophisticated patent services to assist companies in many different technology fields to acquire and protect patent rights strategically in Canada, the United States and the rest of the world. The group is responsible for over 58,000 patent applications and over 4,000 industrial design applications and registrations. Many of the group’s professionals have advanced degrees in the fields of biotechnology, chemistry, physics, electronics, electrical engineering and engineering physics, as well as PhDs in the fields of analytical chemistry, applied chemistry, genetics, nutrition and metabolism, plant biogenetics, oncology and telecommunications.


BLG offers complete trademark portfolio management and enforcement in a variety of industries to help clients to select, register, maintain, license, franchise and enforce their trademark rights and implement their marketing strategies. Our trademark professionals work with clients to understand their brand management, operations, business goals, industry, competitive environment, packaging and advertising, opportunities and threats, and licensing, acquisition and divestiture strategies, to deliver value-added business insight. We have filed over 50,000 trademark applications and registrations in Canada and provide strategic advice to protect those interests throughout the world.


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. Our expert advice and proactive approach in protecting IP matters are widely known to have given clients the competitive advantage required to help them to achieve their business goals.


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. In addition, 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. We also assist in the transfer of technology from government-supported operations and academic organisations to businesses in the private sector.
