Patent Assignment in Turkey

Updated: May 24

In Turkey, the ownership of patents can be transferred to third parties through a patent assignment agreement. A patent assignment agreement is an agreement that the owner of the patent or patent application transfers his right, title, and interest in a patent or patent application to another.

Agreement to be notarized and recorded

A patent assignment must be concluded in writing and approved by a notary public. As per article 148 (4) of the Industrial Property Code numbered 6769 (“Code”), the approval from a notary is a requirement for validity.

The assignment agreement must be signed by either the authorized signatories of the parties or their attorneys assigned through a power of attorney before the notary public. If the assignment agreement is to be signed outside of Turkey, the respective assignment must be notarized, apostilled in the respective country, and the respective notarized and apostilled copy of the agreement must be translated into Turkish by a sworn translator.

Although the notary approval has a constitutive effect between the parties of the agreement, the assignment of the patent must also be recorded with the Turkish Patent and Trademark Office (the “Office”) for the patent assignment to become enforceable towards third parties.

For the assignment to be recorded with the Office:

  • A petition requesting the recordation of the assignment and a copy of the notarized assignment agreement must be submitted to the Office; and

  • An official recordation fee of the assignment, which is TRY 3,140 in 2024 for each patent, must be paid to the Office.

The Office does not require the patent attorney to have a power of attorney for this recordation application.

Scope of the patent assignment agreement

In addition to a detailed agreement, a short agreement may also serve the recording purpose of the patent assignment with the Office provided that the following information is included in the agreement:

  • Identities of the assignor and the assignee,

  • Application number of the patent or patent application to be assigned,

  • Assignment fee.

Assignment of ownership through a merger of companies or a court decision

The ownership of a patent may also be changed as a result of a merger of two companies or a Turkish court decision ruling such change. In such cases, the respective change in the ownership should also be recorded with the Office by submitting a petition requesting the change in the ownership and the official document evidencing such change (instead of the assignment agreement) with the payment of the official recordation fee to the Office.
