Canadian Patent Maintenance Fees

Canada’s Patent Annuities

Renewal fees in Canada are calculated from the filing date of the application (or the effective filing date if the Canadian case has an earlier parent). Fees are due both before and after grant.

Different fees apply dependent on whether the applicant is considered a small or large entity. The tables below detail each fee option. Further information on Entity Types can be found here.

Patent Renewal Rules at the CIPO

Until a Canadian patent is granted, payment of renewal fees must be made through the recorded agent. After the patent grant date, the applicant is free to chose another service to manage renewals, such as RenewalsDesk. Until then, we can still assist by reminding you of the due date, and instructing your agent on your behalf if you wish, reducing your need to deal in multiple currencies.

Late payment is possible for granted patents, similarly to other jurisdictions. However, in Canada, the “grace period” is for a full year rather than the usual six months. An additional late fee of $200 (CAD) is payable.
