Pay patent maintenance fees

From: Canadian Intellectual Property Office

This process explains how and when to pay maintenance fees for your application or patent.

Maintenance fees for divisional applications

Divisional applications carry their own maintenance fees. They are separate from the parent application.

Learn more about maintenance fees for divisional applications in the Manual of Patent Office Practice.

Applications and patents related to section 20 of the Patent Act (items of national security) have special procedures. Be sure to follow the necessary steps.

1. Before you pay

Before you pay, keep the following in mind:

  • Maintenance fees for applications and patents related to section 20 of the Patent Act (items of national security), can't be paid online. Follow the steps required to pay maintenance fees for these applications or patents.
  • You may be eligible to reduce your maintenance fees if you meet the requirements of the small entity status condition. For example, if you are an entity that has fewer than 50 employees or are a university, you are considered a small entity.

All patent fees

When do I pay the patent maintenance fee?

You must pay a maintenance fee for your patent or patent application every year, starting on the second anniversary of your filing date.

You will not receive a reminder that maintenance fees must be paid by a certain date.

If you don't pay your fee, you may lose your intellectual property protection and the technology described in your patent (or application) could be used by others.

You can pay your maintenance fees on a yearly basis or pay for several years at once.

The fees increase on the 5th, 10th and 15th anniversaries of the filing of the patent application.

Tools to help you figure out your fees

How to find your payment history

You can find your payment history by searching for your patent in the Canadian Patents Database. Once you find your patent, click the admin status tab and scroll down to payment history.

What happens if I miss a payment?

If you miss a payment deadline, you'll be charged a late fee regardless of whether a notice to this effect is sent.

  • $150 (CAD) – patent late fee

The latest you can pay your missed payment and late fee is whichever of the following comes later:

  • 6 months after your maintenance fee is due
  • 2 months after you receive the Commissioner's notice saying that they must be paid
