Canada Aird & McBurney LP

Aird & McBurney LP is a patent agency firm which works in union with Aird & Berlis LLP to secure Canadian and worldwide protection and provide IP rights enforcement. Our clients benefit from the integration of agency and legal services within a single, full-service legal organisation.

Aird & McBurney and Aird & Berlis work closely to provide a full range of services in IP procurement, litigation, technology transfers and corporate transactions in connection with all forms of intellectual property, including patents, trademarks, copyrights, industrial designs, trade secrets and domain names.

With the vision and energy propelled by Peter McBurney, a statesman in the field of intellectual property in Canada for almost 50 years, Aird & McBurney was established with a group of leading, highly qualified and highly experienced patent agents that have been working together for over two decades. The firms’ clients range from individual inventors and small start-up companies to universities, hospitals and research facilities to large Canadian and multinational corporations, including Fortune 100 companies.

Securing IP rights

When it comes to securing IP rights, we are vigorous and strategic advocates. We assist clients in acquiring the appropriate IP rights to support their business mandates.

The patent agents of Aird & McBurney are leading practitioners in their specialist fields and hold PhD, MSc or BEng degrees. This technical depth allows them to offer unparalleled service in the preparation, prosecution and maintenance of patent and industrial design applications over a wide range of technologies and industries, including medical and agricultural biotechnologies, diagnostics, pharmaceuticals, chemistry, immunology, genetics, bioinformatics, mining, oil and gas, ‘clean’ or ‘green’ innovation (eg, renewable energy, biofuels, solar power, wind power and water purification), munitions, medical devices, scientific instrumentation, wireless communications, e-commerce software, manufacturing and consumer products.

We have strong relationships with leading associate firms throughout the world. Our clients can be assured that their IP assets will be protected outside Canada with the same sophisticated level of understanding that we provide.

Our trademark agents and lawyers assist clients in developing and managing national and global trademark portfolios. They conduct searches to determine the availability of trademarks for use and registration in Canada and elsewhere, and provide a full range of services relating to the prosecution, registration and maintenance of trademarks.

Conflict avoidance

We provide patentability, freedom-to-operate, infringement and validity opinions, as well as trademark clearances and assistance in designing to avoid patent and trademark infringement. We have extensive experience in developing and managing strategic international IP portfolios while keeping up with the latest technical advances and the rapidly changing global IP climate. We also help our clients increase their brand exposure with the counsel of our lawyers who are experts in regulatory, advertising and marketing matters.


Our clients trust us to protect their IP rights against infringers, counterfeiters and cybersquatters and to defend them against invalid claims made by others. We represent our clients in all types of IP litigation involving patent, trademark, copyright, industrial design, confidential information and trade secret rights, domain names and Uniform Domain Name Dispute Resolution Policy procedures and the Patented Medicines (Notice of Compliance) Regulations, as well as invention ownership, competition law, false advertising, product liability and professional negligence claims. We have substantial experience before courts and tribunals, as well as in the mediation and arbitration of IP and related matters.
