Patent renewal fees in Canada: costs, due dates and grace period
You pay patent renewals in Canada to the CIPO, in CAD, up to year 20. The schedule starts at your second filing anniversary, granted or not. Miss a due date and you get a 6-month grace period, with a surcharge on top.
What are the patent renewal due dates in Canada?
Canada counts annuities from the filing date, and the amount depends on which patent year you are entering. A due date can arrive while the application is still pending.
The first renewal falls due at your second filing anniversary, payable to the CIPO.
For example, if the filing date is 2020-02-01, the first renewal will be due by 2022-02-01.
Every later annuity falls due on the anniversary of the filing date, each year, up to the 19th filing anniversary. Nothing further is due after that.
For example, if the filing date was on September 9, then all subsequent annuities will be due on September 9 each year.

Missed a patent renewal deadline in Canada?
A six-month grace period runs from the day after the due date. You can still pay the renewal fee with a 150 CAD surcharge on top, and the patent continues without interruption. Once the grace period closes, the patent lapses.
If you miss a renewal due date of 15 March 2026, the patent enters the grace period on 16 March 2026. Settle the renewal fee and the surcharge by 15 September 2026 to keep the patent in force.

1. What do I pay while the application is pending?
The same annuities you pay after grant. Canada starts the schedule at your second filing anniversary, and it runs whether or not the office has granted your patent by then.
2. When can I pay the renewal fee?
Whenever you like. In Canada, you can settle renewal fees at any time and pay several annuities together in one go.
3. Can I renew a patent after missing a due date?
Yes. You get a 6-month grace period, starting the day after you miss the due date. Pay the renewal fee plus a surcharge inside that window and your patent stays in force. The surcharge is a flat 150 CAD. Miss the window too and the patent lapses.
4. How long does a patent last?
Up to 20 years from the filing date, as long as you pay every annuity on time. Stop paying and it lapses at the end of the grace period that follows the last due date.
