Who is Eligible to File Patent in Turkey
Any applicant who designates Turkey in a application of PCT Filing may proceed with national phase entry. Eligible filers include:
- Individual inventors
- Domestic Turkish companies
- Foreign corporations and multinationals
- Universities, research institutions, and public entities
- Joint applicants and co-owners
- Legal successors or assignees
Representation Requirement: Applicants who are not resident in Turkey must appoint a Turkish-registered patent attorney or agent to represent them before TÜRKPATENT. Although a formal power of attorney is typically submitted, it is not strictly required for national phase entry; however, local representation is mandatory for prosecution and correspondence.
Entitlement Requirements: Under Turkish practice, the applicant must demonstrate entitlement to file, particularly when the applicant is not the inventor. Turkey allows a declaratory statement regarding the applicant’s rights through assignment or other legal title. Accurate inventor and applicant information is important for enforceability and compliance.
Strict Deadline to file Patent in Turkey– 30/33-Month Rule
Turkey applies the standard 30-month PCT deadline for national phase entry, calculated from the earliest priority date. However, unlike many jurisdictions, Turkey offers the possibility to extend the Patent filing deadline up to 33 months if the applicant pays an additional extension fee.
National phase documentation must be submitted within this timeframe, including:
- Translation into Turkish as required
- Payment of national phase entry fees
- Appointment of local representative
- Filing of supporting documentation
Failing to meet the 30-month deadline without paying the extension fee will prevent timely entry; relief after 33 months is available only in compelling circumstances at the discretion of the Office.
Extensions After the 30/33-Month Deadline
Turkey allows national phase entry up to 33 months from the priority date if the applicant submits the prescribed extension fee. This provides flexibility for applicants who require additional time for translations or finalizing filing strategies.
Even with the extension option, it is recommended that applicants plan to enter the national phase well within 30 months to avoid additional costs and administrative risk.
There is also a provision under national law for consideration of compelling reasons beyond the 33-month period, but such relief is exceptional and uncertain.
Filing Language for Turkey Patent Application
The official language of patent prosecution in Turkey is Turkish. A full Turkish translation of the PCT application — including the description, claims, abstract, and any drawings — must be submitted within two months from national phase entry, subject to payment of the applicable translation fee.
Translations must be carefully prepared, as inaccuracies can adversely affect claim scope, prosecution outcomes, and later enforcement.
Required Documents to File Patent in Turkey
A complete Turkish national phase filing generally requires:
- PCT Application Copy: A certified or formally filed copy of the PCT application establishing continuity into the national phase.
- Turkish Translation: A full translation of the specification, claims, abstract, and Patent drawings into Turkish.
- National Phase Entry Request: A procedural request to enter the national phase under Turkish law.
- Local Representation: Appointment of a Turkish patent attorney or agent.
- Declaration of Entitlement: A statement confirming the entitlement of the applicant to file (e.g., assignment, transfer, or other legal basis).
- Sequence Listings (If Applicable): Electronic sequence listings must be provided in the prescribed format.
Turkey generally does not require formal assignment documents at national entry if a declaration of entitlement is provided; this simplifies initial filing formalities.
Turkey Patent Search and Examination Procedure – Overview
After national phase entry, Turkish patent applications undergo:
- Formal Examination: Reviews compliance with procedural requirements, translations, applicant details, and basic documentation.
- Substantive Examination: Evaluates patentability criteria including novelty check through Patentability Search, inventive step, and industrial applicability in accordance with Turkish law.
Examination begins once the examination request and corresponding fee have been submitted.
Examination Process and Office Actions
Once examination is initiated, TÜRKPATENT may issue Office Actions requiring applicant response on:
- Deficiencies in formal compliance
- Clarifications on applicant details or entitlement
- Novelty and inventive step observations
- Insufficiency or lack of disclosure
Applicants must respond to all Office Actions within prescribed time limits. Amendments to claims or descriptions must remain within the original disclosure. If relevant, the Office may request technical reports or further evidence. Prompt and substantive responses support more efficient prosecution and reduce the risk of refusal.
Deadline for Request for Examination
In Turkey, substantive examination is not automatic and must be formally requested following national phase entry. Applicants must pay the examination fee and file a request for examination within the timeframe stipulated by the Patent Office. Failure to timely file this request can result in suspension of prosecution.
Publication Process and Legal Impact
Turkish patent applications are typically published once formal requirements are satisfied and, in practice, often around 18 months from the earliest priority date. Publication makes the content of the application publicly accessible and places third parties on notice. Although publication does not itself confer enforceable rights, it establishes the application as prior art against other filings.
Grant Process and Enforceability
Following substantive examination and resolution of all objections, an allowance decision is issued. Once grant fees are paid and formalities completed, the patent is published as granted and registered.
A granted Turkish patent confers:
- Only the owner of the patent may use sell or import the invention
- Legal standing to pursue infringement actions in Turkish courts
- Eligibility for injunctions, damages, and supplementary relief
- Customs enforcement against infringing imports
Turkish patent enforcement benefits from specialized intellectual property courts and well-established civil procedures, making Turkish patents commercially enforceable.
Validity Term for Turkey Patent
The term of a Turkish patent is 20 years from the international filing date of the PCT application. Annual renewal fees must be paid to maintain validity, beginning with the third year of the application (and year of filing counted as year zero). Late payments may be accepted with a surcharge under the Turkish annuity regime.
Typical Time to Obtain a Patent in Turkey
The time from national phase entry to grant in Turkey generally falls within:
- 24–36 months under routine prosecution
- Possible extension for complex technical areas or multiple Office Actions
This timeframe provides a predictable prosecution schedule while allowing applicants to respond thoughtfully to examination outcomes.
Annuities and Maintenance Procedure
In Turkey, annual fees (annuities) are due starting from the third year of the national phase application, relative to the original PCT filing date. Annual fees must be paid in advance. If fees are not paid by the due date, a grace period with a surcharge applies. Continued non-payment during the grace period will result in the lapse of rights.

Utility Model Protection in Turkey
Turkey also provides utility model protection as an alternative to standard patent protection. Utility models are suited to incremental inventions and undergo a formal review process with quicker potential grant timelines. Their term and fee structure differs from standard patents, and applicants may elect this route where appropriate for strategic protection of designs or minor innovations.
