Procedures of PCT National Phase Entry in Turkey
Turkey, a PCT contracting state since January 1, 1996, requires applicants to enter the national phase within 30 months from the priority or filing date. This deadline can be extended to 33 months with an additional fee payment.
During this period, applicants must file their national phase applications with the Turkish Patent and Trademark Office (TurkPatent). Missing this deadline may result in losing the opportunity to secure patent rights in Turkey, making timely action essential.
Upon entering the national phase, the PCT application is treated as a national application with Turkey’s IP Office, subject to Turkish patent laws and procedural rules. The applicant must pay the prescribed national filing fees, including an initial fee for the national phase entry and annual maintenance fees.
An initial substantive examination request can be made within a specified time frame, during which patentability is assessed according to Turkey’s patent criteria.

Understanding the Crucial PCT National Phase Deadline
The single most important factor for a successful national phase entry is timing. Under Turkish patent law, the standard deadline for entering the PCT National Phase in Turkey is 30 months from the international filing date or the earliest priority date.
- The 3-Month Extension Grace Period: Turkey uniquely offers a non-extendable three-month grace period. This allows applicants to validly enter the National Phase up to 33 months from the priority date, provided a specific official fee is paid with the national fee. Missing this final 33-month window can result in the loss of your right to obtain a patent in Turkey.

Required Documentation and Language Specifications
The Turkish Patent and Trademark Office (TÜRKPATENT) has specific requirements for the documentation. Submitting these items correctly and on time is non-negotiable.
- Request for National Phase Entry: This is the formal application form requesting the grant of a patent in Turkey.
- Complete Specification: This includes the description, claims, drawings (if any), and the abstract.
- Translation Requirement: The complete specification must be translated into Turkish. If the International Application (IA) was filed in a language other than Turkish, the translation must be submitted. This translation can often be filed within two months of the national phase entry date, but prompt submission is highly recommended to avoid delays and potential issues.
- Power of Attorney (PoA): For applicants not residing in Turkey, the appointment of a registered Turkish Patent Attorney is mandatory. A separate Power of Attorney is typically not required for the national phase entry itself, but your appointed attorney will manage all subsequent correspondence and legal actions on your behalf.

The Role of the Turkish Patent Attorney: Your Local Expert
Foreign applicants must be represented by a registered Turkish patent attorney. Choosing a firm like Akkas & Associates Law Firm, known for its deep local expertise and international perspective, is paramount. Our firm has been providing full-service intellectual property law services in multiple languages since 1992, ensuring clear communication and accurate legal execution.
- A local attorney is indispensable for handling all communications with TÜRKPATENT, managing deadlines, and navigating the substantive examination process. For more on the indispensable role of local counsel, please review our comprehensive services on Turkish Patent Law.

Fees and Annuity Payments
The National Phase Entry involves paying an official filing fee to TÜRKPATENT. If the entry is made during the 30-33 month grace period, an additional fee is required. Furthermore, Turkish law requires applicants to pay annuity fees starting from the third year of the application’s international filing date.
- Proactive Payment Management: If the 3rd or 4th-year annuity falls due on or before the national phase entry date, it must be paid simultaneously to maintain the application’s validity. Our firm meticulously tracks these dates, ensuring no valuable rights are inadvertently lost due to missed maintenance payments.
Examination and Potential for Accelerated Grant
Once the national phase entry is complete and the requisite documents are filed, the application enters the examination stage. Turkey applies a post-grant opposition system.
- Substantive Examination Request: This must be requested by the applicant and the corresponding fee paid, typically within three months of the official notification confirming the national phase entry. The Turkish examiner will assess the patentability criteria: novelty, inventive step, and industrial applicability.
- Chapter II Advantage (If Applicable): If your PCT application entered the national phase under Chapter II (with a positive International Preliminary Examination Report – IPER), it may potentially lead to an accelerated and more direct grant, as the international findings are highly considered by TÜRKPATENT.

Strategy: Utility Model vs. Patent
Turkey also allows for the conversion of a PCT application into a Utility Model application upon National Phase Entry, provided the invention meets the specific criteria (e.g., typically excludes methods, pharmaceutical, and chemical claims).
- Considering the Scope: Utility models offer protection for a shorter term (10 years, non-renewable) but typically involve a faster and less rigorous granting procedure as they only require novelty and industrial applicability, excluding the ‘inventive step’ requirement. We can help you assess the best route—patent or utility model—to maximize your protection in Turkey.
Post-Grant Protection and Enforcement
The successful grant of your patent in Turkey is the beginning, not the end, of your IP protection journey. Post-grant, your rights are enforceable against infringers in the Turkish courts.
- IP Litigation Expertise: Should your patent rights be challenged or infringed upon, having a seasoned litigation team is crucial. Akkas & Associates Law Firm has extensive experience in IP litigation and nullity lawsuits, offering robust defense and enforcement strategies.

FAQs About PCT National Phase Entries in Turkey
Q1: What is the primary deadline for PCT National Phase Entry in Turkey?
The mandatory deadline is 30 months from the earliest priority date (or filing date if no priority is claimed). There is a final, non-extendable grace period of three months, allowing entry up to 33 months with an additional fee.
Q2: Is the Turkish translation mandatory upon entry?
Yes, the complete specification (description, claims, abstract, and drawings) must be translated into Turkish. This translation should generally be filed upon entry, but the Turkish Patent and Trademark Office (TÜRKPATENT) allows for a period of up to two months from the national phase entry date to submit the Turkish translation.

Q3: Do I need a local Turkish Patent Attorney to file the National Phase?
Yes. Applicants who are not residents of Turkey are required to be represented by a registered Turkish patent attorney. Akkas & Associates Law Firm provides this mandatory representation.
Q4: Are the PCT search results considered by TÜRKPATENT?
Yes. The International Search Report (ISR) and the Written Opinion of the International Searching Authority (WO/ISA), or the International Preliminary Examination Report (IPER), are highly valuable. The Turkish examiner considers these reports during the substantive examination process.
Q5: Can I convert my PCT application to a Utility Model in Turkey?
Yes, it is possible to enter the National Phase as a Utility Model application, provided the subject matter is eligible (i.e., not a method, pharmaceutical, or chemical invention). A utility model offers a shorter term of protection but a typically faster granting process.
