Country Guide: Filing a Patent in Turkey

Turkey is a major emerging economy with a population of approximately 85 million, a large and diversified manufacturing sector, and a geographic position that makes it simultaneously a European, Middle Eastern, Central Asian, and North African market hub. Turkey is a candidate for EU membership — a process that has shaped Turkish IP law significantly — and its customs union with the EU creates deep commercial integration with European markets despite Turkey's non-member status.

For inventors in automotive parts, textiles, chemicals, machinery, electronics, construction materials, defence technology, and pharmaceuticals — sectors where Turkish companies are significant manufacturers and exporters — Turkey is a commercially relevant patent jurisdiction with a substantive, improving examination system.

The Hard Truth About Turkish Patents

Turkey's patent system has improved dramatically over the past decade. The Turkish Patent and Trademark Office (Türk Patent ve Marka Kurumu — TÜRKPATENT, previously known as TPE) modernised significantly following the entry into force of the new Industrial Property Code (Law No. 6769/2017), which replaced the outdated decree-law that had governed Turkish IP since the 1990s and brought Turkish patent law into full alignment with European and TRIPS standards.

The Hard Truth is not about systemic deficiencies in Turkey's law — the 2017 Code is a genuinely modern statute. It is about the practical challenge of being a non-EU, non-EPO jurisdiction that is deeply economically integrated with the EU:

Turkish patents are territorial. Turkey is not a member of the EPO. A European patent validated in the EU member states does not cover Turkey. An inventor who files at the EPO and validates across Germany, France, Italy, the Netherlands, and Spain has not obtained any Turkish protection. This is a gap that many inventors — even experienced ones — fail to identify.

Turkey's customs union with the EU creates enforcement exposure without automatic patent protection. Products can move freely between Turkey and the EU under the customs union, but IP rights do not follow automatically. A product that infringes your European patent can be manufactured in Turkey, imported into the EU, and your European patent provides no defence against the Turkish manufacturing. You need a Turkish patent to address the manufacturing source.

For any inventor with EU patent protection and manufacturing exposure to Turkey — which covers most technology areas given Turkey's significant industrial base — the absence of a Turkish filing is a strategic gap worth closing.

TÜRKPATENT: Overview

The Turkish Patent and Trademark Office (Türk Patent ve Marka Kurumu — TÜRKPATENT), headquartered in Ankara, is Turkey's national IP authority. TÜRKPATENT is a signatory to the Patent Cooperation Treaty, the Paris Convention, the European Patent Convention (as a non-EU EPC extension state), and the WIPO-administered treaties.

Turkey's relationship with the EPO: Turkey is an extension state of the EPC — not a full member. This means that EPO patents can be "extended" to Turkey through a separate national validation procedure, giving Turkey coverage within the EPO's geographic framework without Turkey being a full Contracting State. This is similar to how Morocco, Tunisia, and several other non-EU countries participate in the EPO system.

For practical purposes: if you file an EPO application, you can include Turkey in your coverage by paying a Turkish extension fee and filing a Turkish validation — without a separate national application at TÜRKPATENT. This is the most efficient route for European patent coverage that includes Turkey.

Types of Patent Protection

Invention Patent (Patent):

• Term: 20 years from filing date
• Examination: Full substantive examination under the 2017 Code
• Covers: Products, processes, and applications thereof

Utility Model (Faydalı Model):

• Term: 10 years from filing date
• Examination: Formal examination only — no substantive novelty or inventive step examination before registration
• Covers: Products (three-dimensional objects and devices) — not processes
• Registration time: 4–6 months typically
• Similar to German Gebrauchsmuster or Chinese utility model in structure

The Turkish utility model is particularly useful for fast protection while a full patent application is in examination — the same dual filing strategy used in China and Germany can be applied in Turkey.

What Is Patentable in Turkey

Turkey's Industrial Property Code 2017 defines patentable inventions as new, involving an inventive step, and industrially applicable. Turkish patentability standards are explicitly aligned with European (EPO) standards — the 2017 Code incorporates European patent law principles directly.

Excluded from patentability:

• Discoveries, scientific theories, mathematical methods
• Mental acts, business methods, games — as such
• Computer programs as such (though software-implemented inventions with technical character may be patentable, consistent with EPO practice)
• Literary, artistic, and aesthetic works (protected by copyright)
• Methods for treatment of humans or animals by surgery, therapy, or diagnosis
• Plant varieties and animal breeds, essentially biological processes for producing them (though microbiological processes and their products are patentable)
• Inventions contrary to public order or morality

Turkish patent law and the EPO test: Because Turkey has aligned its patent law with the EPC, EPO jurisprudence is highly persuasive — though not binding — in Turkish patent examination and litigation. Examiners at TÜRKPATENT frequently apply EPO reasoning, particularly the problem-solution approach for inventive step analysis. Applicants who have prosecuted at the EPO will find Turkish examination conceptually familiar.

Filing Routes

Route 1: EPO Extension

The most efficient route for inventors who are already filing at the EPO. Turkey can be designated as an EPC Extension State in an EPO application for a modest additional fee. After EPO grant, the patent is validated in Turkey through a national validation procedure at TÜRKPATENT:

• Filing a Turkish translation of the patent claims (a full translation of the specification is not required — claims only)
• Paying Turkish validation fees
• Appointing a Turkish patent attorney for the validation and subsequent maintenance

Cost: Approximately USD $500–$1,500 for the EPO extension fee and Turkish validation, plus attorney fees of $500–$1,500. Far less than a separate Turkish national application through full examination.

Coverage: A validated EPO extension patent in Turkey provides the same legal protection as a Turkish national patent and is enforced in Turkish courts as a Turkish patent right.

Route 2: Direct National Application at TÜRKPATENT

File a Turkish national patent application directly at TÜRKPATENT through its online filing portal. Applications must be in Turkish.

Language: All TÜRKPATENT filings must be in Turkish. Foreign applicants must provide Turkish-language specifications, claims, and abstracts. An English specification can be submitted initially, with a Turkish translation required within 3 months.

Patent attorney requirement: Foreign applicants must appoint a Turkish patent attorney (patent vekili) registered with TÜRKPATENT.

Filing fees (approximate):

• Basic application fee: TRY 500–3,000 (approx. USD $15–$90 at current rates — Turkish lira amounts are subject to significant exchange rate variation)
• Search fee: TRY 1,000–5,000
• Examination fee: TRY 2,000–8,000
• Annual renewal fees: escalating from low amounts in early years

Note: Turkish government fees are denominated in Turkish lira, which has experienced significant inflation and exchange rate volatility. Current fee amounts in USD should be verified with a Turkish patent attorney at the time of filing.

Route 3: PCT National Phase

PCT national phase entry at TÜRKPATENT within 30 months of the international priority date. Turkish translation must be filed at national phase entry.

Examination at TÜRKPATENT

The Examination Process

Under the 2017 Industrial Property Code, TÜRKPATENT examiners conduct full substantive examination — novelty, inventive step, and industrial applicability — consistent with European (EPO) standards.

Examination timeline: TÜRKPATENT examination timelines have improved under the 2017 Code but remain variable. First substantive examination actions typically issue within 18–30 months of the examination request (which must be filed within 36 months of the filing date).

Common rejection grounds:

Lack of inventive step: Turkish examiners apply the problem-solution approach familiar from EPO practice. The identification of the "objective technical problem" and the assessment of whether the solution would be obvious to a skilled person follows EPO methodology.

Claim clarity: Turkish examination applies EPO-equivalent clarity requirements. Claims must be clear, concise, and supported by the description.

Software and business method claims: Turkish examination follows EPO practice — claims must have "technical character" to be patentable. Abstract algorithmic and business method claims receive exclusion rejections; claims tied to specific technical implementations and effects may proceed.

Search Outsourcing

Turkey has outsourcing agreements with the EPO and several national patent offices for prior art searching. A TÜRKPATENT application can request that the prior art search be conducted by the EPO (at EPO fees) — a mechanism that both improves search quality and provides the applicant with an international-standard search report early in prosecution.

Enforcement in Turkey

The Civil Courts

Patent infringement in Turkey is litigated in specialised civil courts (Fikrî ve Sınaî Haklar Hukuk Mahkemesi — Intellectual and Industrial Property Rights Civil Courts) that exist in major cities. Istanbul, Ankara, and Izmir are the primary venues for significant patent cases.

Timeline: Turkish patent infringement cases typically take 2–4 years at first instance. Appeals to the Regional Courts of Justice (Bölge Adliye Mahkemesi) and ultimately the Court of Cassation (Yargıtay) add further time.

Preliminary injunctions: Available in Turkey (ihtiyati tedbir) and increasingly granted by Turkish courts in clear patent infringement cases. Turkish courts assess: seriousness of the right asserted, urgency, and balance of interests.

Customs enforcement: Turkey's customs authorities can be engaged to detain imported goods suspected of IP infringement. Recording patents and trademarks with Turkish Customs (Gümrük ve Ticaret Bakanlığı) is practical for inventors concerned about infringing imports — particularly relevant given Turkey's role as both a manufacturer and a transit point for goods entering the EU.

The EU Customs Union Dimension

Turkey's customs union with the EU has an important IP dimension for enforcement. Turkish customs cooperates with EU customs authorities on IP enforcement under the customs union framework. For inventors with both EU and Turkish patent protection, coordinated border enforcement across both jurisdictions can be effective against manufacturers who produce in Turkey and export to the EU.

A Worked Example: The Customs Union Gap

A German engineering firm held a European patent for a specialised industrial coupling mechanism, validated in Germany, France, Italy, Spain, Poland, and the Netherlands. The patent was strong — clear claims, thorough prosecution history, positive EPO examination.

The firm discovered that a Turkish manufacturer was producing an apparently infringing version of the coupling and selling it: (a) in Turkey, (b) to customers in the EU, and (c) to customers in the Middle East.

The IP position:

• EU sales: The European patent covered the EU member state markets. The firm was able to send C&D letters to EU distributors carrying the Turkish product and, ultimately, file an injunction application in a German court against the German distributor.
• Turkish sales: The firm had no Turkish patent. It could not take action against the Turkish manufacturer in Turkish courts, and could not stop Turkish domestic sales.
• Middle East sales: The firm had patents in the UAE and Qatar but not Saudi Arabia. Coverage was partial.

What filing a Turkish EPO extension at the time of EPO grant would have cost: Approximately EUR 800 in EPO extension fees plus EUR 1,200 in Turkish validation and attorney fees — EUR 2,000 total.

What the gap cost: EUR 150,000 in German litigation costs to stop the EU distribution channel, plus ongoing Turkish market losses estimated at EUR 300,000/year, plus a licensing negotiation that resulted in less favourable terms than it would have if the Turkish manufacturer faced simultaneous Turkish enforcement.

The lesson: The EPO extension to Turkey is one of the cheapest and highest-return IP filings available to any European patent holder. Its omission is a strategic error that costs disproportionately when Turkish manufacturers are involved.

Turkey-Specific Strategic Considerations

Always extend your EPO application to Turkey. For the cost of a few hundred euros in extension fees plus modest validation costs, you cover Turkey within your EPO application. Given Turkey's role as a major EU supplier across virtually all manufacturing sectors, this extension pays for itself the first time a Turkish manufacturer considers your product.

File a Turkish utility model simultaneously with the national application. For technology entering the Turkish market quickly, the utility model's 4–6 month registration time provides immediate enforcement capability while the patent application is in examination. The same dual filing strategy used in China and Germany applies effectively in Turkey.

Monitor Turkish patent publications in your technology area. TÜRKPATENT's online database (turkpatent.gov.tr) provides access to Turkish patent applications and grants. Turkish companies — particularly in automotive, defence, and chemicals — are increasingly active patent filers. Monitoring Turkish filings provides competitive intelligence on Turkish R&D directions.

Turkey as a gateway to Central Asia. Turkey has bilateral investment treaties and commercial relationships with many Central Asian countries. Turkish-registered IP can support Turkish partners who distribute into Azerbaijan, Kazakhstan, Uzbekistan, and other regional markets. A Turkish patent in a licensing agreement with a Turkish distributor covering regional sales is a practical commercialisation structure.

Cost Summary

The EPO extension route is far cheaper and faster than direct TÜRKPATENT filing for inventors already using the EPO. Use it unless there is a specific reason to file nationally.
