Intellectual Property Litigation
Goodmans is the “best patent litigation firm in Canada” (Chambers Canada) and “… the number one firm in Canada by far…simply put, there is Goodmans and then there is the rest” (IAM Patent 1000). Industry leaders repeatedly turn to Goodmans when the need arises to assert their intellectual property rights, whether it be patents, trademarks or copyright or to defend against claims of patent, trademark or copyright infringement. Our Goodmans IP litigation bench is deep, with industry-recognized lawyers and leaders of the future working alongside several in-house PhD-level scientists.
In 2024, the Group received numerous recognitions, including Canada Firm of the Year - Patent Disputes and Impact Case of the Year at the Managing IP Americas Awards, Intellectual Property Firm of the Year at the Benchmark Canada Awards, Leading IP Law Firm - IP Patents at the Lexology Awards: North America, Impact Case of the Year at the LMG Life Sciences Americas Awards, and Patent Litigation Firm of the Year, Canada at the Global IP Awards.
Our lawyers have acted in the leading cases regarding IP at the Supreme Court of Canada and the Federal Court of Appeal, where they have shaped Canadian IP law through original thinking and importing the most thoughtful legal solutions from other jurisdictions. Our lawyers provide thought leadership through their advocacy, teaching and participation in leading IP organizations, such as the Intellectual Property Institute of Canada and the Canadian Bar Association’s National IP Section.
We also assist clients in protecting, registering, transacting and managing Intellectual Property, including patents, trademarks and copyright, and have unparalleled experience litigating complex and high-stakes IP litigation in the pharmaceutical, high technology, telecommunications, oil and gas, mining and manufacturing sectors. If and when disputes arise, clients trust us to assert IP and to defend against IP claims brought by others.
Clients from a multitude of industries choose Goodmans when they want client-focused, tailor-made strategies for building and managing IP portfolios and designing around the IP of their competitors. While our industry-specific experience is vast, we recognize each client is unique and approach each mandate with empathy and a passion to learn and understand our client’s business and how IP can and should play a role in it. As a business firm, our IP group regularly engages in transactional work, including conducting due diligence, transferring assets and taking security interests.
