Registering a trademark is only the beginning of a commercial journey. As one of a business’s most valuable intellectual assets, a trademark grants its owner the power to transfer exclusive rights or authorize others to use the mark. Under the 2024 Law on the Protection of Industrial Property, trademark owners are entitled—under specific conditions—to transfer the economic rights arising from the mark or to license these rights to third parties.

In this article, we provide a clear, step-by-step guide to the concept of assignment of a Trademark, the legal process involved, and the documentation required to formalize a change of ownership.

Types of Trademark Transfer

A trademark can be transferred in two primary ways:

  1. Voluntary (Contractual) Transfer: This occurs when the brand owner, of their own free will and via a formal contract executed at a notary office, transfers ownership of the mark to another natural or legal person.
  2. Involuntary (Non-Contractual) Transfer: This occurs by operation of law, most commonly when the owner of the mark passes away and ownership shifts to their legal heirs.

When Can a Trademark Be Transferred?

A common misconception is that a trademark can only be transferred after a final registration certificate has been issued. In reality, a brand can be transferred at any of the following stages:

  • Pre-filing: Before the application (declaration) is submitted.
  • Pending: After filing the application but before the certificate is issued.
  • Post-registration: After the final certificate is issued (the most common scenario).

Understanding the Trademark Assignment Agreement

A trademark assignment agreement is a contract through which the owner (assignor) transfers their ownership rights to another party (assignee), either for a consideration (payment) or free of charge. This document serves as the legal record of the change in ownership.

Scope of Transfer

  • Partial vs. Total: An owner may transfer exclusive rights for all registered classes of goods/services or retain certain classes while transferring others.
  • Duration: The assignment may cover the entire remaining term of the trademark’s validity or be limited to a specific period.
  • Sub-assignment: Legally, the assignee is not permitted to re-assign these rights to a third party unless the “right to transfer to others” is explicitly granted within the original contract.

Legal Conditions and Requirements

For a transfer to be legally valid and registrable with the Intellectual Property Office (IPO), the agreement must meet the following criteria:

  • Written Form: The agreement must be in writing and executed at an official notary public office.
  • Official Registration: The transfer must be recorded in the Trademark Register of the Industrial Property Office, and a notice of the transfer must be published.
  • Legal Capacity: Both the assignor and assignee must have the legal capacity to enter into a binding transaction.
  • Validity of the Mark: A mark that has expired (and passed its renewal grace period) or has been formally annulled cannot be transferred.
  • Intent and Consent: The transferor must be the rightful owner, and both parties must enter the agreement voluntarily, free from duress or coercion.
  • Specificity: The subject matter must be clearly defined. The contract should precisely state the trademark registration number, the classes involved, and a description of the figurative elements to avoid ambiguity.

Steps for the Legal Transfer of a Trademark

If you intend to transfer a trademark in Iran, follow these steps:

  1. Request for Inquiry Letter: Visit a notary public to obtain an official inquiry letter addressed to the Intellectual Property Office regarding the brand’s status.
  2. Online System Filing: Submit a request for a “Response to Inquiry from Notary Public Offices” via the Intellectual Property Office’s online portal.
  3. IPO Confirmation: Experts at the Registration Office verify that the mark is free from legal encumbrances, prohibitions, or seizures. A positive response is then sent electronically to the notary.
  4. Drafting the Assignment Contract: Once approved, the parties meet at the notary office to sign the formal Contract.
  5. Uploading Documents: The new owner must upload the deed to the IPO system and file a request for the “Registration of Change of Ownership.”
  6. Official Gazette Publication: After approval by the Industrial Property Office, the change is published in the Official Gazette to notify the public and third parties.
  7. Endorsement: Finally, the change is endorsed on the back of the original trademark certificate, or a new certificate is issued in the name of the assignee.

Documents Required for Transfer

For Natural Persons (Individuals):

  • Copies of birth certificates and national ID cards (for both parties).
  • The original trademark registration certificate.
  • The Assignment Contract executed at the notary office.
  • Proof of activity for the new owner (e.g., business license, exploitation permit, or commercial card).
  • Receipt of payment for transfer fees.
  • Power of Attorney (if a legal representative is handling the process).

For Legal Entities (Companies):

  • The Official Gazette of incorporation and the latest notice of authorized signatories.
  • Identity documents of the authorized directors.
  • The Assignment Contract executed at the notary office.
  • The original trademark registration certificate.
  • The company’s tax code and national ID number.
  • Power of Attorney (if a legal representative is handling the process).

 

Conclusion

As examined in this article, the process of transferring a trademark is more than a simple administrative formality; it is a strategic decision and a decisive step in the life cycle of a mark. F From the initial inquiry at the notary office to the final publication in the Official Gazette, each step requires precision. Given the complex and specialized nature of intellectual property agreements, it is recommended that, in order to prevent potential risks and ensure the rights of both parties, you consult experienced lawyers or specialized intellectual property consultants before taking any steps to draft such agreements.
