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.
