CIPO's Official Patent Fees for 2025 and 2026

Our Canadian IP lawyer Edmund Xie understands that the cost of securing a patent is a major factor in any innovation budget. Beyond legal and drafting fees, the Canadian Intellectual Property Office (CIPO) charges a series of mandatory official fees that span the life of your invention. Critically, these fees are subject to annual increases under the Service Fees Act, meaning the cost of your patent is literally rising every year.

Based on the official CIPO schedule, here is a detailed, two-year outlook on the critical fees you need to budget for, highlighting the substantial savings available if your business qualifies as a Small Entity.

The Crucial Distinction: Small Entity vs. Standard Fees

The most important step is determining your entity status. Qualifying as a Small Entity (generally, a business with fewer than 100 employees or a university) provides discounts of up to 50% on almost every official fee. Getting this determination wrong, however, can put your entire patent at risk. All prices below are in Canadian Dollars (CAD).

1. Initial Filing and Application Fees

The first cost you encounter is securing your application's filing date.

• The Application Fee for a Small Entity is $234.90 in 2025, rising to $241.24 in 2026.

• For all other applicants (Standard Fee), this cost is significantly higher: $579.42 in 2025, increasing to $595.06 in 2026.

This initial fee sets the stage for the rest of the application, but it merely opens the door; it does not start the review process.

2. The Examination Cost and Claim Fees

The Examination Fee is typically the largest single payment. This is the fee CIPO charges to assign an examiner to review your invention for patentability.

• For a Standard Case, the Request for Examination Fee is $1,158.84 in 2025, jumping to $1,190.13 in 2026.

• The Small Entity rate offers major savings at $469.80 in 2025, increasing slightly to $482.48 in 2026.

Furthermore, CIPO penalizes unnecessarily broad or complex applications. If your application includes more than 20 claims, an additional fee is required for each claim over that limit. This claim fee is $57.42 (SE) / $114.84 (Standard) in 2025, rising to $58.97 (SE) / $117.94 (Standard) in 2026. This per-claim cost can quickly inflate your budget if the specification is not carefully drafted.

3. Long-Term Maintenance (Annuity) Fees

Even while your application is still pending, you must pay annual Maintenance Fees starting from the second anniversary of your filing date to keep the application alive. These fees increase as the patent matures:

• For Years 2 through 4, the annual fee is $58.68 (SE) / $130.50 (Standard) in 2025, which will rise to $60.26 (SE) / $134.02 (Standard) in 2026.

• For Years 5 through 9, the fees climb higher, reaching $104.40 (SE) / $289.19 (Standard) in 2025, rising to $107.22 (SE) / $297.00 (Standard) in 2026.

• Fees continue to increase dramatically up to the 20th anniversary, where the final Standard Fee is a substantial $1,000.00 (2025 rate).

Crucially, CIPO does not forgive deadlines. If you miss a maintenance deadline, you will face a non-adjustable Late Fee of $150.00 (for both 2025 and 2026), risking the eventual lapse of your entire patent right.

Secure Your Innovation and Control Your Budget

The Canadian patent process is a significant financial commitment, complicated by rising annual fees and complex procedural requirements. A successful patent strategy means more than just a strong invention; it requires flawless administrative execution and intelligent budget forecasting.

Don't let procedural missteps or overlooked deadlines—and the corresponding surcharges—compromise your most valuable intellectual property.

Our Canadian IP lawyer and patent agent Edmund Xie specializes in navigating these complex CIPO fee structures, ensuring your application is correctly classified, filed, and maintained, allowing you to focus on your innovation, not the bureaucracy.

Qualifying for CIPO's Small Entity Patent Fees 

For Canadian inventors and startups, the cost of securing a patent is a major budgetary consideration. Fortunately, the Canadian Intellectual Property Office (CIPO) offers a lifeline: the Small Entity status, which provides a 50% reduction on the majority of official patent fees, including filing, examination, and maintenance fees.

However, qualifying for and correctly claiming this status is one of the most critical administrative steps in the patent process. A mistake can be extremely costly, potentially invalidating your patent.

What Defines a Small Entity?

CIPO's Patent Rules provide a precise definition for a Small Entity. To qualify, an applicant must be one of the following:

1. A University.

2. An entity that employs fewer than 100 employees.

The "100 Employee" Threshold: This threshold is not based on full-time equivalents; it includes all employees, whether full-time, part-time, or contract, on a worldwide basis.

Critical Disqualifications: When You Must Pay the Standard Fee

The most common mistake innovators make is failing to account for ownership or licensing agreements. Even if your company is small, you are disqualified from using the reduced fees if, at the time the fee is paid, the applicant is:

1. Controlled by a Large Entity: If your company is directly or indirectly controlled by an entity (other than a university) that has 100 employees or more. This often applies to subsidiaries of larger corporations.

2. Obligated to Transfer/License Rights to a Large Entity: If you have transferred or licensed (or have a non-contingent obligation to transfer or license) any rights in the claimed invention to an entity (other than a university) that has 100 employees or more.

This second point is crucial. If you are a small startup but have an existing agreement to license your invention to a major corporation for distribution, you may be immediately disqualified from claiming Small Entity status.

The Consequence of Incorrect Classification

The determination of your Small Entity status is made at the filing date of the application and must be declared before or at the time of your first fee payment.

The Danger of Underpayment: If you mistakenly claim Small Entity status when you are not eligible and pay the reduced fee, CIPO treats the payment as deficient. This means your application fees were never technically paid in full. If the full, standard fee is not remitted promptly after the error is discovered, your patent application or granted patent could be deemed abandoned or expired—a catastrophic outcome that can lead to the permanent loss of your patent rights.

The Small Entity discount is a powerful tool to make patent protection accessible, but it is not a matter for simple guesswork. For companies involved in collaboration, investment talks, or licensing negotiations, the criteria for qualification become complex and require specialized analysis.

As a Canadian  patent and IP lawyer, Edmund can help innovators accurately determine their entity status, ensure compliance with all CIPO regulations, and manage the critical deadlines that protect their patent rights.

Using Third-Party Prior Art Submission to Challenge a Competitor's Application at CIPO 

Our Canadian patent lawyer Edmund Xie often advises clients who discover a competitor attempting to patent an invention that they know is not new or not inventive. The Canadian Intellectual Property Office (CIPO) provides a mechanism for any third party to intervene in this process by filing prior art.

This strategy is a powerful, low-cost way to challenge the validity of a patent application before it is granted, saving you the expense and complexity of full-blown post-grant litigation.

What is Third-Party Prior Art?

Prior art is any information or documentation publicly disclosed about an invention before the filing date of the patent application in question. It is the body of public knowledge against which an invention's patentability (its novelty and inventiveness) is measured.

Under Section 34.1 of the Patent Act, any third party can file this relevant prior art with CIPO. The goal is simple: to alert the Patent Examiner to existing public knowledge that could block the competitor from obtaining a valid patent.

Strategic Reasons to File Prior Art

Filing third-party prior art is a proactive and tactical move that benefits your business in two key ways:

1. Improves Patent Quality: The submission ensures that the CIPO Examiner has the most complete picture of the state of the art. This helps prevent competitors from obtaining a patent for an invention that was, in reality, already known or obvious.

2. Blocks Competitors Efficiently: By submitting pertinent evidence during the examination phase, you might be able to prevent a competitor from obtaining exclusive rights without the significant legal costs associated with seeking a re-examination after the patent is granted.

The Procedure: How to File Prior Art with CIPO

The process for filing third-party prior art is straightforward, but it must be executed correctly to be considered by the Examiner.

1. Eligibility: Anyone can file prior art once the patent application has been made available to the public (typically 18 months after the earliest filing date).

2. Submission Requirements: Your submission must clearly indicate:

   • The relevant Canadian patent application number.

   • The prior art itself (a copy of the document, patent, or publication).

   • A concise explanation of why the prior art is pertinent to the claimed invention (i.e., how it impacts the claimed novelty or inventiveness).

3. No Confidentiality: It is essential to understand that any prior art filed becomes part of the public application file. CIPO will return any submission that requests confidentiality.

What Happens After Filing?

Once submitted, CIPO acknowledges receipt and notifies the patent applicant that a third-party submission has been made. However, you will not be involved in the subsequent discussions.

The Patent Examiner will only consider the information after examination has been requested by the applicant. If the Examiner finds the submitted prior art to be pertinent, they will use it as a reference to determine if the claimed invention is truly patentable.

In the fast-paced world of innovation, remaining vigilant against overreaching competitors is crucial. Filing prior art is a vital component of a comprehensive IP watch strategy, allowing you to influence the patent system before patents are granted.

If you suspect a competitor is attempting to claim intellectual property that rightfully belongs in the public domain, you need experienced IP counsel to strategically gather the evidence and present it effectively to CIPO.
