Protecting Your Invention: Key Steps to Filing a Patent in Quebec

September 1st, 2025

Developing an innovative idea is an exciting moment, but protecting it is essential to prevent it from being copied or exploited without your consent. In Quebec, filing a patent is an effective way to secure your exclusive rights to your invention. Here are the key steps to successfully complete this process.

1. Verify the patentability of your invention
Before starting the procedure, make sure your invention is new, useful, and non-obvious. It must not have been publicly disclosed before filing. A prior art search in patent databases will help confirm its novelty.

2. Choose the appropriate type of patent
There are different types of patents, such as invention patents or utility models. Choose the one that best matches the nature and use of your invention to ensure optimal protection.

3. Prepare a detailed description
Your application must include a clear and precise description of your invention, along with mandatory drawings or diagrams. The more detailed the description, the easier it will be to defend your rights in the event of a dispute.

4. File the application with the Canadian Intellectual Property Office (CIPO)
The application to the Canadian Patent Office (CIPO) can be filed online through the CIPO website (if you have set up an account beforehand) or by registered mail. It must include the required forms as well as the applicable fees. Once submitted, your application will be reviewed by an examiner within approximately 12 to 18 months.

5. Respond to the examiner’s observations
It is common for the examiner to raise objections or request clarifications. Respond promptly and clearly to avoid delays in the process.

6. Maintain your patent
Once granted, the patent must be kept active by paying annual maintenance fees. This step is essential to preserve your exclusive rights for the entire protection period.

By following these steps, you maximize your chances of obtaining strong and lasting protection for your invention in Quebec. A well-drafted and properly filed patent is a strategic asset to safeguard your innovation and strengthen your position in the market. For this reason, it is strongly recommended that you work with a patent agent to adequately address the often strict requirements of examiners.
