Under Canadian patent law, a joint owner of a patent can make, use, and sell the invention independently, but they cannot license or assign their share to a third party without the explicit consent of all other co-owners. Drafting a formal Joint Ownership Agreement with a Canadian law firm is critical to prevent your innovation from becoming commercially deadlocked.
Innovation is rarely a solo endeavour. 🤝 Whether you are a group of engineering students at the University of Waterloo, researchers in a Montreal lab, or startup co-founders in Calgary, collaborative invention is the norm. When two or more people contribute to the conception of an invention, they are legally considered co-inventors, and by default, joint owners of the resulting Canadian patent.
However, the default rules provided by the Canadian Intellectual Property Office (CIPO) and the federal Patent Act often shock new entrepreneurs. 🚨 Unlike in the United States, where a co-owner can independently license the patent to massive corporations without asking the others, Canadian law is highly restrictive. If one of your co-founders disappears or refuses to sign a licensing deal, the entire commercialization of your product can be frozen indefinitely.
Step-by-Step Guide to Managing Joint Patent Ownership in Canada
Avoiding a messy legal battle requires proactive planning before the patent is ever filed. 📍 Establishing clear terms early on protects the relationships of the co-founders and the valuation of the startup. Here is how you can effectively manage joint patent rights.
Step 1: Accurately Identifying All Co-Inventors
Legally, an inventor is someone who contributed to the inventive concept-the “lightbulb” moment. 💡 People who merely followed instructions to build the prototype, or the investor who simply wrote the cheque, are not legally inventors. Including someone on the patent application who did not invent, or leaving off someone who did, can legally invalidate the entire patent in federal court.
Step 2: Understanding Default CIPO Restrictions
If you file the patent together without any written contract, the default rules apply. 📜 You and your partners can each manufacture and sell the product yourselves and keep the profits without sharing. However, if a massive company offers to license the technology for millions of dollars, every single co-owner must agree and sign the deal. If one person says no, the deal collapses. This is the biggest legal pitfall of joint ownership in Canada.
Step 3: Drafting a Joint Ownership Agreement
To override these restrictive default rules, you must work with a local patent lawyer to draft a Joint Ownership Agreement (sometimes part of a broader Founders’ Agreement or IP Assignment). 📄 This contract dictates exactly how the patent will be handled. The agreement can stipulate that majority rules on licensing decisions, how royalties will be divided, and what happens if one inventor wants to sell their shares.
Step 4: Alternatively, Assigning Rights to a Corporation
The most common and secure solution for Canadian startups is to avoid joint ownership altogether. 💼 Instead of holding the patent in the individual names of the inventors, all co-inventors sign an “Assignment Agreement” transferring their rights to a single incorporated company (e.g., “TechCo Inc.”). The company then owns 100% of the patent, and the inventors own shares in the company, making commercialization and licensing vastly simpler.
Step 5: Recording the Agreement with CIPO
Once your agreements are signed, it is crucial to record these documents with the government. 📝 Your law firm will submit the Assignment or Joint Ownership Agreement to CIPO to be officially registered against the patent file. This provides public notice of who actually controls the intellectual property rights.
How Much Does it Cost to Manage Joint Ownership?
Preventative legal work is always cheaper than a lawsuit between founders. 💰 Budgeting for proper IP agreements is a necessary cost of doing business in Canada.
- Drafting a Joint Ownership Agreement: Hiring a business or IP lawyer to draft this specific contract usually costs between $1,500 CAD and $3,500 CAD.
- Drafting an IP Assignment Agreement: Simpler assignment documents generally cost $500 to $1,500 CAD.
- CIPO Recordal Fee: Registering an assignment or agreement with CIPO costs exactly $100 CAD per patent document.
- Incorporation Costs: If you choose to form a company to hold the IP, federal incorporation and initial minute book setup ranges from $1,000 to $2,500 CAD.
| Action / Right | Default Canadian Rule (No Contract) | With an IP Assignment to a Startup |
|---|---|---|
| Making & Selling the Invention | Allowed by any owner independently | Controlled exclusively by the Startup |
| Licensing to a Third Party | Requires 100% unanimous consent | Controlled by the Startup’s executives |
| Selling/Assigning the Patent | Requires 100% unanimous consent | Controlled by the Startup’s board |
How Long Does the Process Take?
Drafting and executing the necessary legal agreements is relatively fast. ⌖ A law firm can usually prepare a Joint Ownership Agreement or Assignment Agreement in 1 to 3 weeks. Once the document is signed and submitted to CIPO, the government processing time to officially record the transfer on the federal register takes roughly 4 to 8 weeks.
Frequently Asked Questions (FAQ)
What happens if an employee invents something?
Generally, if an employee is hired specifically to design or invent, the rights belong to the employer. However, standard Canadian employment contracts always include an IP Assignment clause to ensure there is no legal ambiguity regarding ownership.
Can a joint owner stop me from selling the product?
No. Under the default Canadian rules, any joint owner can manufacture, use, and sell the patented invention without permission from the other owners, and they do not have to share the profits with them.
Is US joint patent ownership different than Canada?
Yes, significantly. In the United States, a joint owner can license the patent to a third party without the consent of the other owners. In Canada, one joint owner cannot grant a valid license without the agreement of all co-owners.
Do we have to split the royalties 50/50?
Not if you have a contract. A Joint Ownership Agreement can dictate any profit-sharing split you agree upon (e.g., 70/30 based on capital contribution). Without an agreement, it can lead to complex litigation over revenue sharing.
Can one co-owner abandon the patent?
No single co-owner can actively withdraw or abandon the patent application against the wishes of the others. However, if maintenance fees are not paid because co-owners are fighting, CIPO will deem the patent abandoned.
