File a Canadian patent application: Pay the final fee


7. Pay final fee

If your patent application is allowed, you' ll be sent a notice of allowance that will ask for the basic portion of the final fee as well as an excess page fee for each page of the specification and drawings after 100 pages, and an excess claims fee for each claim over 20 that was not paid when requesting examination.

If you do not pay the final fee by your deadline (4 months from the mailing date of the notice), your patent application is deemed abandoned.
