Canadian Trademark Assignment: How to Transfer and Record Ownership

Canadian Trademark Assignment: How to Transfer and Record Ownership

Trademark assignments — the transfer of ownership from one party to another — are a regular part of business operations. Whether through a sale, merger, acquisition, or corporate restructuring, transferring a Canadian trademark requires proper documentation and recording with the Canadian Intellectual Property Office (CIPO) to ensure the new owner's rights are fully protected.

This guide covers the legal requirements, recording procedures, and strategic considerations for Canadian trademark assignments under the Trademarks Act (R.S.C., 1985, c. T-13).

Pro tip: If you're acquiring a trademark, run a free trademark check to verify the mark's current status and identify any potential issues.

What Is a Trademark Assignment?

A trademark assignment is the transfer of ownership rights in a trademark from the assignor (current owner) to the assignee (new owner). In Canada, trademark assignments can cover:

• Registered trademarks — marks currently on the Canadian Trademarks Register
• Pending applications — applications that have been filed but not yet registered
• Common law rights — unregistered trademark rights based on use in Canada

Unlike some jurisdictions, Canada does not require that the goodwill of the business be transferred along with the trademark. However, transferring goodwill is strongly recommended to ensure the mark retains its distinctiveness and value.

Types of Trademark Assignments

Complete Assignment

The entire trademark — covering all goods and services in all territories — is transferred to the new owner.

Partial Assignment

Only a portion of the trademark rights is transferred. This can involve:

• Specific goods/services — the assignor retains the mark for some classes while transferring others
• Geographic limitations — though less common in Canada since trademarks are national in scope

Note: Partial assignments can create complexities. If the same mark is owned by different parties for different goods/services, confusion issues may arise.

Assignment Through Merger/Acquisition

When one company acquires another, trademark rights typically transfer as part of the acquired company's assets. This may happen through:

• Asset purchase agreements
• Share purchase agreements (where the trademark-owning entity is acquired)
• Corporate mergers and amalgamations

Recording an Assignment with CIPO

Why Record?

While trademark assignments are valid between the parties without recording, recording with CIPO is strongly recommended because:

• Public notice — the transfer appears on the Canadian Trademarks Register
• Enforceability against third parties — unrecorded assignments may not be enforceable against parties who deal with the registered owner in good faith
• Chain of title — maintains a clear ownership history
• Renewal and maintenance — ensures CIPO correspondence goes to the correct owner

How to Record

To record a trademark assignment with CIPO, submit:

1. Written request for recordal of the transfer
2. Evidence of the assignment — a copy of the assignment agreement or other documentation evidencing the transfer
3. Details of the new owner — full legal name and address
4. Registration or application numbers affected
5. Filing fee — applicable CIPO recording fee

The Assignment Agreement

A well-drafted trademark assignment agreement should include:

Essential Terms

• Identification of the mark(s) — registration/application numbers, mark description
• Identification of the parties — full legal names and addresses of assignor and assignee
• Scope of the transfer — complete or partial; which goods/services and territories
• Effective date — when the transfer takes effect
• Consideration — the price or value exchanged (can be nominal)
• Goodwill transfer — explicit statement about whether the goodwill of the business is included

Additional Provisions

• Representations and warranties — the assignor's confirmation of valid ownership and no encumbrances
• Cooperation clause — obligation to execute further documents as needed for recording
• Indemnification — protection against claims arising from the assignor's prior use
• Transition provisions — timeline for the assignor to cease using the mark

Licensing vs. Assignment

Not every transfer of trademark usage rights is an assignment. Licensing allows another party to use the mark while the original owner retains ownership.

Under the Trademarks Act:

• Sections 28-31 govern trademark licensing in Canada
• The trademark owner must maintain quality control over the licensee's use
• Without proper quality control, the mark may become vulnerable to cancellation for naked licensing
• License agreements should be documented in writing, though oral licenses are not prohibited

When to License vs. Assign

Special Considerations

Security Interests

Trademarks can be used as collateral for financing. Security interests in trademarks should be properly documented and may be recorded with CIPO and under applicable provincial personal property security legislation.

Bankruptcy and Insolvency

In bankruptcy proceedings, trademarks form part of the debtor's estate and can be assigned by the trustee. Special rules under the Bankruptcy and Insolvency Act may apply.

International Considerations

If the Canadian trademark is part of a larger international portfolio:

• Assignments should be coordinated across all jurisdictions
• Madrid Protocol international registrations have specific transfer procedures through WIPO
• Tax implications of cross-border trademark transfers should be considered

Common Pitfalls

1. Failing to record — unrecorded assignments create enforcement risks
2. Incomplete documentation — vague or missing terms in the assignment agreement
3. Forgetting related applications — ensure all pending applications are included in the transfer
4. Ignoring common law rights — the assignment should cover unregistered rights as well
5. Neglecting renewal obligations — the new owner must track and meet renewal deadlines
6. Not updating agent records — if the mark was filed by a Canadian trademark agent, update the agent of record

After the Assignment

Once the assignment is recorded, the new owner should:

• Verify the register — confirm CIPO has updated ownership records
• Update trademark agent — ensure your Canadian agent has current contact information
• Monitor the mark — watch for potentially conflicting applications using the CIPO database
• Plan for renewal — track upcoming renewal deadlines
• Begin using the mark — consistent use prevents non-use cancellation risks
