The TURKPATENT API for trademark search

Türk Patent ve Marka Kurumu (TÜRKPATENT) is the Turkish national authority responsible for examining and registering trademarks, patents, designs, utility models, and geographical indications in Turkey. Headquartered in Ankara and operating under the Ministry of Industry and Technology, TÜRKPATENT received roughly 366,500 domestic trademark applications in 2024 — ranking Turkey sixth worldwide for trademark filings and second only to EUIPO within Europe, ahead of every other national office on the continent. WIPO data placed Turkey fourth globally for domestic trademark registrations in 2024 with ~284,800 registrations granted. By any measure, TÜRKPATENT is one of the busiest national trademark offices on the planet, and the corpus of historical Turkish trademark records is well into the millions.

The legal foundation for the modern Turkish register is Industrial Property Law No. 6769, which entered into force on 10 January 2017. The IP Code consolidated five separate decree-laws — including the previous trademark decree-law No. 556 of 1995 — into a single statute covering trademarks, patents, designs, utility models, and geographical indications. The 2017 reform shortened the opposition window from three months to two months from the publication of the application in the Official Trademark Bulletin (and the opposition period cannot be extended), introduced administrative cancellation procedures handled by TÜRKPATENT itself rather than the courts, and modernized the absolute-grounds examination process. Applications filed before 10 January 2017 are still assessed under the old Decree-Law 556 regime; applications filed on or after that date fall under Law 6769 — a split that matters when querying historical prosecution data. Turkey has been a Madrid Protocol member since 1 January 1999, so trademark protection in Turkey can be obtained either through a direct national TÜRKPATENT filing or by designating Turkey (TR) through a WIPO International Registration.

TÜRKPATENT exposes the register through EPATS (the e-Government services portal at epats.turkpatent.gov.tr) and through the public trademark search at online.turkpatent.gov.tr — both also accessible via Turkey's e-Devlet single-sign-on at turkiye.gov.tr. The public search is comprehensive and free, with bilingual Turkish/English UI and lookups by mark text, application number, registration number, owner name, Nice class, and trademark type (well-known marks, geographical indications, sound marks, motion marks, etc.). There is no documented public bulk-data API or programmatic REST feed for third-party developers — TÜRKPATENT publishes the register through the web UI and EPATS, not through a developer-grade endpoint comparable to USPTO ODP or EUIPO eSearch. Signa is building its TÜRKPATENT connector for Q4 2026; on launch it will normalize the Turkish-language register, the Law 6769 event vocabulary, and Madrid designations of Turkey into the same unified schema used for USPTO, EUIPO, and every other office.
