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.

First renewal

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 year after

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.

Design renewal guide

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.

Patent renewal FAQ

What happens to an Albanian patent before it has been granted?

There are no annuities due in Albania before the patent is granted. Once the patent has been granted, annuities must be paid annually in accordance with the rules described above under the section Due Dates.

When can I pay the renewal fee in Albania?

At present, the opening of the renewal payment window in Albania has not been officially specified. Consequently, we are unable to confirm the earliest date on which the renewal fee can be paid.

Can I renew a patent after I miss a renewal due date?

Yes, it is possible to renew an Albanian patent after its renewal due date. If you fail to pay the renewal fee before the due date, a grace period of 8 months is given wherein the renewal fees can still be settled. When entering the grace period you will incur a surcharge fee to be settled along with the renewal fee. If you wish to maintain the patent, both the renewal fee and the surcharge fee will have to be settled.

For example, if a patent has a renewal due date of 2021-05-31 and the due date is missed, the patent will enter the grace period from 2021-06-01. After this point both the renewal fee and the surcharge fee will need to be settled by 2022-01-31. Failure to pay these fees before the surcharge due date will result in the patent lapsing.

How long do patents last in Albania?

A patent will stay in force for 20 years in Albania from the filing date if successfully renewed in accordance with the rules described above. If the patent is not renewed, it will lapse by the end of the grace period measured from the latest renewal due date.
