Canadian Patent Maintenance Fees
Canada’s Patent Annuities
[alert type=”success”]
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.
