\nData in this report is sourced from IP Pilot and is accurate as of September 2026, based on the number of patent filings first published between 2021 and 2025. Because patent data may be subject to reporting delays in public databases, figures may fluctuate over time. International case exchange figures are based on the top 1,000 search results in IP Pilot for each direction.<\/p>\n<\/blockquote>\n
Canada occupies a distinctive position among the jurisdictions IP Pilot tracks: a bilingual, common-law-and-civil-law market with deep economic integration with the US, and a Quebec-based francophone IP bar operating alongside its common-law counterparts elsewhere in the country. Between 2021 and 2025, 218,455 patent filings were recorded across 992 firms, agents, and self-represented applicants \u2014 but that volume is heavily concentrated. The top 50 firms alone accounted for 199,657 filings, or 91.4% of the total market, and the top 25 accounted for 176,658 filings \u2014 80.9% of everything filed in Canada over the period. For a market with nearly a thousand active filers, that is a striking degree of concentration in a small set of firms.<\/p>\n
This report ranks the 25 largest patent prosecution firms in Canada by published filing volume from 2021\u20132025, examines how that volume shifted year over year, and looks at where Canadian filings originate and where they are sent \u2014 before drawing out what the patterns mean for firms building referral relationships in this market.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
