Ridout & Maybee LLP has offices in Toronto, Ottawa and Mississauga, and consistently ranks as one of Canada’s top IP law firms in both Canadian and international surveys of in-house counsel. Founded in 1893, Ridout & Maybee is one of Canada’s oldest intellectual property firms. James Edward Maybee, one of the original founders of the firm, was the first President of the Patent and Trademark Institute of Canada (now the Intellectual Property Institute of Canada).

The majority of the firm’s professionals have advanced degrees in science, engineering and IT, as well as law. This means they have a deep understanding of what their clients do, the industries they serve, and the way they do business. The firm knows the key role that IP plays in their clients’ individual strategies for growth and success.
