Our Firm’s History

As a leading protector of intellectual property in Canada since 1893, our firm files an average of 3,000 patent and 1,000 trademark applications per year. We are one of the country’s longest successfully operating IP firms.

Our co-founder, John G. Ridout, was the author of one of the first Canadian textbooks on patents, Ridout on Patents, published in 1894.

J. Edward Maybee was the first President of what is today the Intellectual Property Institute of Canada. Six Ridout & Maybee LLP partners have held this title.

Today, our position at the forefront of IP law is evidenced by our editorial role in the Canadian Patent Reporter, the country’s authoritative journal on IP case law, with Marcus Gaille serving as editor.
