Budget 2026 Patent Changes: What Canadian Inventors and Businesses Need to Know
On November 5, 2026, the Government of Canada tabled its federal budget. It proposes several changes that affect patents. Some will change how patent ownership is recorded. Others aim to protect businesses from unfair patent threats, and one could help companies pay for patent protection.
In this post, we explain the key Budget 2026 patent changes in plain language.
Important: These are proposals. None of the patent law changes are in force yet. Parliament must pass a law or the government must make new regulations first.
Quick Summary: Budget 2026 Patent Changes at a Glance
- Patent ownership: Changes in who owns a patent would have to be registered with the Canadian Intellectual Property Office (CIPO).
- Patent demand letters: New rules would set minimum requirements for letters that accuse a business of patent infringement.
- Tax credits: The cost of getting and keeping a patent could count toward the SR&ED tax credit program.
- Federal Court funding: The court that hears most patent and trademark cases would get $58 million over four years.
- More to come: The government says further measures will be announced in spring 2027.
1. Patent Ownership Changes Would Have to Be Registered
Today, when a patent is sold or transferred, the new owner is not always required to record the change with CIPO. As a result, the public record does not always show who really owns a patent.
Budget 2026 proposes to fix this. The government plans to amend the Patent Act “to require changes in patent ownership to be registered with the Canadian Intellectual Property Office.” The goal, according to the budget, is to give businesses and investors clearer information about who owns Canadian patents.
Why this matters: If you buy, sell, or license patents, recording the transfer would likely become a required step rather than an optional one. Investors would also find it easier to check who owns a patent before they put money into a company. This would help with due diligence too. That’s the process of checking a company’s assets before a deal.
What we don’t know yet: The budget does not say when this change will take effect. It also doesn’t say what will happen if an owner fails to register a transfer. We’ll be watching for the bill.
2. New Rules for Patent Demand Letters
A patent demand letter is a letter that claims your business is infringing someone’s patent. It usually asks you to pay money or stop selling a product. Many of these letters are legitimate. However, some are vague or misleading and are sent simply to pressure businesses into paying.
To address this, Budget 2026 proposes “developing new regulations under the Patent Act to establish minimum requirements for written patent demand letters.” According to the budget, the goal is to protect Canadian businesses from vague or misleading patent infringement claims intended to extract nuisance payments.
Why this matters: If you receive a demand letter, these rules could give you more information to judge whether the claim is real. On the other hand, if you send demand letters to enforce your own patents, you’ll likely need to include certain details in them.
What we don’t know yet: The budget does not list what the minimum requirements will be. Those details will come later, when the regulations are drafted.
Tip: If you receive a patent demand letter today, don’t ignore it and don’t pay right away. Talk to a patent professional first.
3. SR&ED Tax Credits Could Cover Patent Costs
The Scientific Research and Experimental Development (SR&ED) program is Canada’s main tax incentive for research and development. Right now, it mainly covers research work. In contrast, the cost of protecting the invention that comes from that research is generally not included.
Budget 2026 proposes to change that. Under the proposal, the cost of registering and maintaining intellectual property protection would become an eligible SR&ED expense.
What types of IP would be covered?
According to the government’s tax measures document, eligible IP would include:
- patents
- certificates of supplementary protection (an extra layer of protection for some drug patents)
- plant breeders’ rights
- copyrighted software
This applies to IP protected under Canadian law or similar laws in other countries.
What costs would count?
Eligible costs would include those “reasonably incurred to obtain and, where applicable, maintain protection” for eligible IP. In addition, fees paid to foreign patent offices would be eligible. However, supporting work would only count if it is done in Canada.
What would not count?
- Costs to enforce IP rights, such as patent litigation
- Costs not directly connected to securing and maintaining IP rights
Other key details
- The IP must come from an eligible SR&ED project. In other words, the invention needs to come out of research that already qualifies under the program’s existing rules.
- Selling the IP has consequences. If you later sell the IP, “recapture rules” would apply. This means some of the tax benefit may have to be paid back.
- Timing: The measure would apply to taxation years that begin on or after Budget Day (November 5, 2026).
- Cost to government: The broader SR&ED expansion is estimated at $930 million over five years.
Why this matters: For many small and mid-sized Canadian companies, patent costs are a real barrier. This change could make it easier for innovative businesses to protect their inventions in Canada and abroad.
Note: This is a tax proposal. It’s a good idea to speak with your accountant or tax advisor about how it may apply to you.
4. More Funding for the Federal Court
Most patent and trademark lawsuits in Canada are heard in the Federal Court. Budget 2026 proposes $58 million over four years, starting in 2027–28, for the Courts Administration Service. The funding would help reduce a translation backlog and “help the Federal Court manage elevated caseloads.”
Why this matters: If the funding works as intended, patent and trademark cases may move through the court more smoothly.
A Quick Note for Trademark Owners
Budget 2026 does not propose any changes to trademark law. Trademarks are also not included in the proposed SR&ED change. However, trademark cases are heard in the Federal Court, so the new court funding may help those cases move faster too.
What Should You Do Now?
While these changes are not yet law, there are smart steps you can take today:
- Review your patent records. Make sure past ownership changes are recorded with CIPO. This is good practice now and may soon be required.
- Track your patent costs. If your company does SR&ED work, keep clear records of patent filing and maintenance fees, both in Canada and abroad.
- Talk to your tax advisor. Ask how the proposed SR&ED change could affect your next claim.
- Get advice on demand letters. Whether you send or receive them, a patent professional can help you respond the right way.
- Stay informed. We’ll update our clients as bills and regulations are released.
Frequently Asked Questions About Budget 2026 Patent Changes
Are the Budget 2026 patent changes in effect now?
No. The Patent Act changes and the demand letter rules are proposals. They need new legislation or regulations before they take effect. The SR&ED change is also a proposal, but it would apply to taxation years beginning on or after November 5, 2026, once passed.
Will I have to register a patent assignment with CIPO?
That is what the government proposes. Budget 2026 says it plans to amend the Patent Act to require changes in patent ownership to be registered with CIPO. The details and timing have not been released.
What is a patent demand letter?
It’s a letter claiming that a business is infringing a patent, usually asking for payment or for the business to stop an activity. Budget 2026 proposes minimum requirements for these letters.
Can foreign patent fees count toward SR&ED?
Under the proposal, yes. Administrative fees paid to IP offices outside Canada would be eligible. However, supporting activities must be done in Canada to qualify.
Are more IP changes coming?
Yes. The government says further measures will be announced in spring 2027.
