Maintenance fee due dates

This timeline illustrates the maintenance fees and due dates for the lifetime of an application or patent. These fees are for small entities — for standard entities, double the fees.

This image illustrates the cost of maintenance fees for each year up to the maximum of 20 years from filing. For years 1 and 2, the filing fee covers this period. The fee is then $50 for years 2-5, $100 for years 6-10, $125 for years 11-15 and $225 for years 16-20.

Note: The time periods show the years from the filing date.

* The filing fee covers this period.

** If the due date falls on a weekend or a day when the Patent Office is closed, then the due date is the next business day.

Example:

For instance, if you filed an application on May 7, 2007, and maintained it for the full 20-year term from the filing date (to May 7, 2027), your maintenance fees would be:

3 X $50 = $150
5 X $100 = $500
5 X $125 = $625
5 X $225 = $1125
for a total of C$2400

The following fees apply to both small and standard entities:
