Frequently Asked Questions

Türkiye is a contracting state to the European Patent Convention, but a granted European Patent (kind code B1) does not automatically take effect here. Validation is the national step that gives the granted EP the same effect as a Turkish patent, enforceable before the Turkish courts and the Turkish Patent and Trademark Office. Until the patent is validated in Türkiye, your client has no enforceable protection in this territory, even though the EP has been granted.

A granted European Patent is a bundle of national rights, not a single unitary right that covers every member state automatically. For the patent to have legal effect in Türkiye, it must be brought into force nationally through validation. If this step is missed, the invention is unprotected in Türkiye and a third party could use it locally without infringing any Turkish right, regardless of the EP grant.

The validation must be requested within three months of the date the grant is mentioned in the European Patent Bulletin. This period runs from the bulletin date, not from when you receive any notice, so the safest course is to instruct your local Turkish attorney early. The required Turkish translation may follow within a further period after the request, subject to a late fee, but the request itself is governed by the three-month window. If the deadline is close, contact us straight away so the file can be prepared without delay.

Under Turkish law, a foreign applicant or patent holder who has neither a residence nor a place of business in Türkiye must appoint a registered Turkish patent attorney to act before the Turkish Patent and Trademark Office. You cannot file the validation directly from abroad. This is a legal requirement, not a formality. Validation Türkiye is a registered Turkish patent attorney and acts as your mandatory local attorney of record, working peer to peer with foreign counsel so you keep the client relationship while we handle the Turkish procedure.

Yes. Validation in Türkiye requires a certified Turkish translation of the granted patent. The Turkish text defines the scope of protection that can be enforced locally, so the translation must be accurate and faithful to the granted version. We prepare the translation through qualified technical translators and review it for legal and technical consistency before filing, so the protected scope matches the granted claims as closely as the languages allow.

To open the file and prepare your quote, the essentials are the EP application or publication number and the date of grant. To complete the work we will also confirm the name and address of the applicant or patent holder and the granted text of the patent, including the description, claims and any drawings. With the number and the grant date alone we can already confirm the validation deadline and begin preparing your quote.

First, you send us the EP number and the date of grant, and we confirm the validation deadline and the scope of work. Second, we send you a clear, transparent quote. On your approval we file the validation request with the Turkish Patent and Trademark Office and arrange the certified Turkish translation within the prescribed terms. Once validated, the European Patent takes effect in Türkiye as a national patent, and we keep the file under management so nothing lapses.

Once validated, the European Patent has effect in Türkiye as a national Turkish patent and is enforceable locally before the courts and the Turkish Patent and Trademark Office. To keep the patent in force for its term, annual renewal fees must be paid to the Turkish Patent and Trademark Office. We can monitor these terms and manage the renewals on your behalf, so the protection your client secured is not lost to a missed administrative deadline.

There is no single flat figure. The total is made up of official fees payable to the Turkish Patent and Trademark Office together with translation and our professional fee, and the translation volume, driven mainly by the number of claims and pages, is the largest variable. For that reason we do not quote a generic price. Send us the EP number and the date of grant and we will reply, typically within one business day, with your confirmed validation deadline and a transparent quote, with no hidden charges, so you and your client know the cost before any work begins.
