Patents for Canadians

Canadian Maintenance Fee Requirements

 

Annual maintenance fee payments must be made in Canada both for pending applications and for issued patents.

The first annual maintenance fee payment is due no later than the end of the second year from the International Filing date. If the International Filing date is 11 or 12 months after the priority date, then the deadline to make the first annual maintenance fee payment is 5-6 months after the 30 month national entry deadline. Care should be taken as this date may occur sooner if the international filing has been made early in the priority year.

Government charges for the first three payments are $50 per year for small entity and $100 per year for a large entity. Government charges rise in subsequent years.
