Turkey, as a G20 economy and a major manufacturing hub bridging Europe and Asia, is a critical market for technology and innovation. For international companies, securing patent protection in Turkey is not just a legal formality but a strategic necessity to prevent infringement in this key industrial zone.
While Turkey is a member of the EPC (European Patent Convention) and PCT, direct National Patent Applications are often preferred for specific strategies. The process is governed by the Industrial Property Code No. 6769 (“Code 6769”), which is fully harmonized with EU standards.
At Goklu Law & IP Firm, we offer streamlined patent filing and registration services for international IP firms, ensuring that your invention is protected with maximum scope and minimum bureaucracy.
Filing Requirements
We have simplified the filing process for our international associates.
No Power of Attorney (PoA) Required: Unlike many other jurisdictions, no Power of Attorney (neither notarized nor simple signed) is required to file a patent application in Turkey.
Patent Specification & Language:
Filing in Foreign Language: The patent specification (Description, Claims, Abstract, and Drawings) can be submitted in Turkish OR in the official language of countries party to the Paris Convention or WTO (e.g., English, Chinese, German, French).
Translation Deadline: If the application is filed in a foreign language (to secure the filing date), the Turkish translation must be submitted to the Turkish Patent and Trademark Office (“TURKPATENT”) within 2 months from the filing date.
Applicant and Inventor Details:
For Corporations: Full legal name, nationality, and registered address.
For Individuals: Full name, nationality, gender, and address.
Inventor(s): Full name, nationality, gender, and address.
Statement of Right (Relationship)
If the Applicant and the Inventor are different entities (e.g., a company owning an invention created by an employee), the Code 6769 requires a declaration of how the right was transferred (e.g., Employment Relationship, Contractual Assignment, or Shareholding).
No physical assignment deed or contract needs to be submitted to the TURKPATENT. A simple declaration of the relationship type in our instruction is sufficient.
The Registration Procedure
The national patent procedure in Turkey consists of 5 main stages:
Step 1: Filing & Formal Examination: Upon filing, TURKPATENT conducts a formal examination to check if the application complies with procedural requirements (forms, fees, etc.). There is no technical examination at this stage.
Step 2: Search Report: A search report is mandatory for all patent applications.
Request Deadline: The request for a search report must be filed either at the time of application or within 12 months of the filing date (or priority date). The report lists documents publicly available worldwide to assess whether the invention is novel (worldwide novelty), involves an inventive step, and is industrially applicable.
Step 3: Publication
Standard Publication: The application and the Search Report are published in the Official Patent Bulletin 18 months after the filing/priority date.
Early Publication: Upon request, the application can be published earlier (e.g., immediately after the Search Report is issued).
Step 4: Substantive Examination: The request for the Examination Report must be filed either at the time of application or within 3 months following the notification of the Search Report.
TURKPATENT examines whether the invention complies with the patentability criteria of Code 6769. If the application does not comply, the applicant is notified and allowed to submit opinions or make amendments without exceeding the scope of the original application. This notification process regarding deficiencies may be repeated up to three times. For each notification, the applicant is granted three months to respond by submitting arguments/evidence to demonstrate patentability or by revising the claims. If no response is provided within this deadline, the application is deemed withdrawn.
Step 5: Grant Decision
Grant: If the examination concludes that the application meets the patentability criteria, a Decision to Grant is issued and published in the Bulletin.
Grant with Amendments: If the examiner decides that the patent can be granted only with specific changes, the applicant is given 2 months to make these amendments.
Registration Certificate: Upon payment of the certificate fee, the Patent Registration Certificate is issued and notified to us.
Conclusion
Securing a national patent in Turkey is a structured process that demands strict adherence to statutory deadlines, particularly regarding the search and examination requests.
Additionally, if you have a prior application filed in another Paris Convention or WTO member country, you may claim a Right of Priority within 12 months from the date of the first filing. This ensures that your application in Turkey benefits from the date of your original filing.
