Did you know that understanding your patent costs upfront is one of the most effective ways to build a stronger IP strategy in Canada?

For startups, independent inventors, and established businesses, knowing the cost of filing a patent in Canada before beginning the process helps you budget effectively and avoid unexpected expenses. Patent protection is not a one-time payment—it involves several official government fees throughout the life of a patent application and the granted patent.

This guide explains the latest 2026 Canadian Intellectual Property Office (CIPO) official fees and the major cost considerations involved in obtaining patent protection in Canada.

What Does It Cost to File a Patent in Canada?

The Canada patent application cost consists of several government fees payable at different stages of the patent process. The total amount depends on factors such as applicant status (standard or qualifying small entity), the number of claims, and how long the patent is maintained.

1. Patent Application Filing Fee

To file a patent application with the Canadian Intellectual Property Office (CIPO), the official government filing fee is:

• Standard applicant: CAD 595.06
• Qualifying small entity: CAD 241.24

These fees cover the filing of a Canadian patent application. Professional drafting fees charged by patent agents are separate from the official government fees.

2. Examination Request Fee

A Canadian patent application is not automatically examined. The applicant must submit a request for examination within the prescribed deadline.

The current examination fees are:

• Standard applicant: CAD 1,190.13
• Qualifying small entity: CAD 482.48

Applications that were the subject of an international search by CIPO acting as the International Searching Authority may qualify for a reduced examination fee.

3. Excess Claim Fees

Canada charges additional fees when a patent application contains more than 20 claims.

The fee for each excess claim is:

• Standard applicant: CAD 117.94 per claim
• Qualifying small entity: CAD 58.97 per claim

Keeping the claim set concise during drafting can help reduce overall filing costs. Additional excess claim fees may also become payable at the time of grant if they were not previously paid.

4. Maintenance Fees

Patent protection in Canada requires annual maintenance fees beginning from the second anniversary of the filing date.

Maintenance fees increase progressively over the life of the patent. For example:

*Applicable where an additional patent term is available under Canadian law.

Missing a maintenance payment may result in the patent application or granted patent lapsing.

5. Final (Issue) Fee

Once the patent application is allowed, a final government fee must be paid before the patent is granted.

Current fees are:

• Standard applicant: CAD 446.03
• Qualifying small entity: CAD 181.20

Additional charges may apply if the specification exceeds 100 pages or if excess claim fees remain outstanding.

Government Fees vs. Professional Fees

Many inventors assume that the official CIPO fees represent the total cost of obtaining a patent. In reality, government fees are only one component of the overall investment.

Professional costs may include:

• Prior art searches
• Patent drafting
• Patent drawings
• Filing and prosecution
• Responses to examination reports
• Portfolio management and maintenance

Since every invention is unique, professional fees vary depending on the complexity of the technology and the scope of protection sought.

Why Understanding Patent Costs Matters

The cost of filing a patent in Canada is a long-term investment rather than a single government payment.

Planning your patent budget helps you:

• Avoid missed maintenance payments that could result in the loss of valuable patent rights.
• Take advantage of reduced government fees if you qualify as a small entity under Canadian patent law.
• Manage claim drafting strategically to minimize excess claim fees.
• Present a stronger intellectual property portfolio to investors, business partners, and potential acquirers.

Filing a patent is only the beginning of protecting your innovation. A well-planned intellectual property strategy considers filing costs, prosecution, maintenance fees, and long-term commercial objectives.

Frequently Asked Questions

How long does a patent last in Canada?

A Canadian patent generally remains in force for 20 years from the filing date, provided all required maintenance fees are paid on time.

Do small businesses receive reduced patent fees?

Applicants that qualify as small entities under the Canadian Patent Rules are eligible for reduced official government fees for most patent-related services.

Can I file a Canadian patent application without a patent agent?

Yes. However, patent law is highly technical, and errors in drafting, claim scope, or prosecution can significantly reduce the value of your patent. Working with a qualified patent professional is strongly recommended.
