Borden Ladner Gervais LLP

As the largest, truly full-service Canadian law firm, Borden Ladner Gervais LLP (BLG) delivers practical legal advice for domestic and international clients across more practices and industries than any other Canadian firm. With over 725 lawyers, IP agents and other professionals, BLG serves the legal needs of businesses and institutions across Canada and beyond – from M&A and capital markets, to disputes, financing, and trademark and patent registration.

BLG’s IP group works closely with you to make protecting and enforcing your intellectual property a top priority. Many of our professionals hold advanced degrees in engineering, technology and scientific fields, have extensive litigation experience and publish in peer-reviewed journals – bringing an insider’s understanding to your most challenging IP issues within Canada and globally.


BLG’s patent professionals can help you maximise assets and devise strategies to protect and manage risk in a global market. Our team can assist you with a wide range of services across the spectrum of science and technology, including:

  • worldwide patent portfolio strategy planning, analysis and development;
  • patentability, infringement, validity and freedom-to-operate opinions;
  • Canadian, US and international patent application preparation and filing; and
  • cost-reduction and cost-benefit analyses of patent strategies.


A trademark’s success hinges on having an experienced legal team that can provide comprehensive trademark portfolio management and enforcement services and offer sound advice on maximising opportunities in an evolving global marketplace. We can help you plan and implement programmes to clear, select, register and enforce trademark and trademark-related rights. Our professionals will work with you to understand your needs in a variety of areas, including:

  • brand management;
  • operations, business goals and industry;
  • packaging and advertising; and
  • opportunities and threats.


With today’s immediate access to digital media, copyright protection and enforcement can significantly affect your bottom line. Whether protecting your copyright or defending them from infringement claims, working with a trusted, proactive team of advisers who can address complex copyright issues across numerous industries and help achieve your business’s goals is critical. Our copyright group’s experience and multidisciplinary approach provides comprehensive assistance in a range of areas, including:

  • copyright due diligence;
  • litigating copyright issues;
  • managing copyright portfolios;
  • copyright protection, including registration;
  • copyright enforcement and licensing; and
  • government copyright policies and legislation.


We understand that intellectual property is one of your most valuable assets and further understand the need to enforce and defend your IP rights. Whether you are pursuing infringers or defending against allegations of IP infringement or misappropriation, it’s essential to have an experienced team of vigilant advocates on your side. Our professionals speak your language and bring together the best of both worlds: the trial experience to communicate highly technical and legal issues to judges, and the technical expertise to help you address IP issues. Our team includes lawyers who specialise in pharmaceutical litigation, including issues with Patented Medicines (Notice of Compliance) Regulations.


BLG’s licensing group can structure comprehensive licensing transactions by exploring the technology’s life cycle, its potential applications to other areas and market direction. We can help you develop and capitalise on your IP portfolio by negotiating and drafting licensing agreements, and drafting and negotiating trademark, copyright, patent, trade secret and know-how licences.

Industrial designs

Protecting the aesthetic appearance of your product is a key part of a comprehensive IP strategy. Industrial designs (design patents in the United States) can provide effective protection against competitors, particularly in industries susceptible to imitation. Our team works with clients across a broad range of industries, including transport, machinery, small/large appliances, furniture, fixtures, garments and footwear, computers, and electronics. We also assist with electronic icons, graphical user interfaces and designs where colour is now protectable as part of a design.

Awards and recognition

BLG has been recognised as a leading firm by some of the most prestigious national and international legal publications, including Chambers Canada 2021, which ranked BLG in Band 1 – the highest level of recognition – in 11 practice areas and recognised 125 lawyers. BLG has been ranked as a leading Canadian firm in patent practice by the 2020 edition of the IAM Patent 1000, with a gold ranking in the area of patent prosecution and a silver ranking for patent litigation.
