How to Enforce a Trademark in Turkey (2026): Civil, Criminal & Administrative Steps for Brand Owners

Trademark enforcement turkey begins with a simple answer: yes, registered rights holders can enforce their marks through three distinct and complementary routes, civil litigation, criminal complaints, and administrative action before the Turkish Patent and Trademark Office (TÜRKPATENT). The governing statute is Law No. 6769 on Industrial Property, which codifies the available remedies, the conduct that constitutes infringement, and the administrative procedures open to brand owners. For international brand owners, in-house counsel and IP managers, the practical challenge is not whether enforcement is possible but which route, or combination of routes, delivers the fastest, most cost-effective result for a given infringement.

This 2026 guide sets out the procedure step by step, with document checklists, realistic timelines, indicative costs and the practical coordination tips that separate a successful action from a stalled one.

1. Overview, can you enforce a trademark in Turkey?

Turkey offers three parallel enforcement tracks, and a well-advised rights holder frequently pursues more than one at the same time. Civil proceedings before the specialised IP civil courts (and, where none exists, the general civil courts of first instance sitting in that capacity) are the primary vehicle for stopping infringement and recovering damages. Criminal complaints, channelled through the public prosecutor and the police, are powerful against deliberate counterfeiting and can produce rapid seizures and deterrent penalties. Administrative remedies before TÜRKPATENT address disputes at the register level, oppositions and certain cancellation proceedings, while invalidation and many cancellation claims are determined by the specialised courts; customs coordination operates alongside these routes.

Standing rests principally on registration under Law No. 6769, which grants the proprietor exclusive rights enforceable throughout Turkish territory. Jurisdiction and venue lie with the designated IP civil and criminal courts in the main commercial centres (notably Istanbul, Ankara and İzmir); where no specialised court exists, the general court of first instance sits in that capacity. The territorial scope is national: a Turkish registration protects the mark across Turkey, and enforcement follows the location of the infringing act or the defendant’s domicile. In short, a rights holder who can prove ownership and an infringing act in Turkey can sue, file a criminal complaint, or initiate administrative proceedings, often in combination.

2. Eligibility, who can bring a claim?

Rights holders: registrant and prior user

The registered proprietor is the default claimant and holds the strongest position, because the certificate of registration issued by TÜRKPATENT is primary evidence of ownership. Law No. 6769 protects registered marks directly. Unregistered marks are not left wholly without recourse: well-known marks and signs used in trade may attract protection under the unfair competition provisions of the Turkish Commercial Code and, in defined circumstances, under Law No. 6769 itself. However, enforcing an unregistered mark is harder, slower and evidentially demanding, which is why registration should always precede any serious enforcement strategy.

Licensees and exclusive licensees

Licensees may enforce in certain circumstances. Under Law No. 6769, an exclusive licensee can generally bring infringement proceedings in its own name unless the licence provides otherwise; a non-exclusive licensee ordinarily must first request the proprietor to act and may bring proceedings in its own name only if the proprietor does not do so within the statutory period, unless the licence provides otherwise. To establish standing, a licensee must produce the executed licence or assignment agreement and, where relevant, evidence of its scope. Where rights have been assigned, the assignee should ensure the assignment is recorded at TÜRKPATENT before filing, to avoid preliminary objections on title.

3. Pre-enforcement checklist: searches, evidence and cease & desist

Conducting a Turkish trademark search

Before any action, confirm the strength and scope of your own rights and assess the defendant’s position. Use the TÜRKPATENT online trademark database as the starting point. A thorough search should cover the relevant Nice classes, the exact mark and close variants, and, critically for the Turkish market, phonetic equivalents and transliterations, since confusion is often assessed on how a mark sounds or is rendered in Turkish. Where the mark uses Latin and Turkish character variants, run both. For acquisition decisions or high-stakes enforcement, commission a formal clearance report from local counsel rather than relying on a raw database result.

Evidence collection and preservation

Weak evidence is the single most common reason enforcement stalls, so build the file before you move. Capture dated screenshots of marketplace listings, seller pages and social media offers. Make test purchases to obtain physical samples and retain the invoice, packaging and shipping records to establish a chain of custody. For online infringement, preserve URLs, seller identities and transaction data. Where authenticity or likelihood of confusion is contested, an expert report strengthens both the infringement case and any later damages claim. Keep every exhibit traceable: a sample without a documented purchase trail is far weaker in both civil and criminal proceedings.

Cease & desist letters

A well-drafted cease & desist letter frequently resolves straightforward matters and, where it does not, becomes valuable evidence of notice. The letter should identify the registered right and its registration number, describe the infringing conduct, demand that it stop within a defined period, and set out the enforcement routes you are prepared to pursue, civil suit, criminal complaint and administrative action. Serve it in a manner that produces proof of delivery, such as a notarised notice (ihtarname). Keep a copy of the letter and the delivery confirmation for the file, because failure to comply after notice supports both urgent relief and damages.

4. Step-by-step trademark enforcement turkey: civil, criminal and administrative routes

This is the core of any enforcement strategy. The three routes differ in who brings them, the standard of proof, the remedies available and the time they take. The guidance below helps match the route to the objective; the stepwise processes that follow set out what typically happens in each.

Civil enforcement

1. File the main suit. Lodge the infringement action at the competent IP civil court, based on the defendant’s domicile or the place of the infringing act. The claim should plead the registered right, the infringing conduct and the relief sought, injunction, destruction, accounting and damages.
2. Request an interim injunction. Apply for provisional relief, either with the main suit or in advance, supported by evidence of the right, the infringement and the urgency. The court may order the infringement to stop and goods to be preserved pending judgment, usually against security.
3. Case management and evidence. The court will typically appoint an expert panel (bilirkişi) to examine confusion, authenticity and market impact. Parties exchange documents, witness statements are taken, and site inspections or sample examinations are arranged.
4. Judgment and remedies. On a successful claim the court can grant injunctive relief, order seizure and destruction of infringing goods, require an accounting of profits, award damages and allocate recoverable attorneys’ fees in accordance with the applicable tariff.
5. Appeal. First-instance judgments may be appealed to the regional courts of appeal (bölge adliye mahkemeleri) and, on points of law, ultimately to the Court of Cassation (Yargıtay). Appeals extend the overall timeline considerably.

Criminal enforcement

1. File a criminal complaint. Submit the complaint to the public prosecutor or the police, identifying the registered right, the counterfeit goods and the suspected infringer. Criminal sanctions for trademark offences are set out in Law No. 6769. Note that criminal protection under these provisions is available for registered marks.
2. Preliminary investigation and raids. The police conduct the investigation and, where justified and judicially authorised, carry out search-and-seizure operations on warehouses, retail premises or market stalls, confiscating suspected counterfeit goods as evidence.
3. Indictment and trial. If the prosecutor is satisfied there is sufficient evidence, an indictment is issued and the matter proceeds before the criminal IP court. Penalties on conviction can include imprisonment and judicial fines, together with confiscation of the infringing goods.
4. Victim’s rights. The rights holder, as the injured party, can participate in the proceedings; a civil claim for damages may run separately alongside or after the criminal case.

Administrative and TÜRKPATENT action

1. Opposition. Oppose a conflicting application during the publication period to prevent a problematic mark from reaching the register.
2. Cancellation for non-use. Seek cancellation of a registered mark for non-use through the administrative procedure before TÜRKPATENT. (Under Law No. 6769, jurisdiction over non-use cancellation was transferred to TÜRKPATENT, with that provision having taken effect in January 2024.)
3. Invalidation. Seek invalidation of a registered mark on grounds such as conflict with an earlier right before the specialised courts.
4. Customs coordination. Register a customs application so that suspected infringing goods can be detained at the border, linking the administrative route to practical interdiction.

Comparison: civil vs criminal vs administrative

In practice, strong trademark enforcement turkey strategies combine routes: a criminal complaint to trigger immediate seizures, a civil suit to secure an injunction and damages, and administrative action to clear the register of a conflicting registration that would otherwise undermine the civil claim.

5. Interim relief and urgent measures: injunctions and seizures

Where delay would cause irreparable harm, for example, a counterfeit shipment about to clear customs or a product launch timed to a trade fair, urgent relief is the decisive tool. The legal basis for provisional measures sits in the Civil Procedure Code (Law No. 6100) and the enforcement provisions of Law No. 6769. The applicant must demonstrate a prima facie valid right, a credible infringement and the urgency of the measure. Courts commonly require security (a bond) to protect the respondent against a wrongful injunction, though the court has discretion over its form and amount.

Timing varies considerably by court and caseload. In some cases the court may rule on an interim injunction application relatively quickly, and measures without first hearing the respondent are possible where justified, but they demand compelling, well-documented evidence and typically higher security, because the court is acting on one party’s account alone. The practical lesson is to assemble the evidentiary dossier before applying: a thin or poorly documented application invites refusal and warns the infringer. Move early, move with evidence, and be prepared to post security.

6. Working with Customs, police and raids, practical coordination

Border and physical enforcement often delivers the fastest commercial result against counterfeiters. Turkish customs, operating under the Ministry of Trade, can detain suspected counterfeit goods where the rights holder has an active customs application on file. To prepare an effective customs dossier, provide the registration certificate, high-quality images distinguishing genuine from counterfeit products, known infringer and shipment details, and clear contact points for rapid verification when goods are detained. Because detentions are subject to statutory deadlines, counsel must be ready to confirm infringement and obtain the necessary court measures promptly once notified.

For inland enforcement, coordination with the police and the prosecutor is essential. A criminal complaint supported by test-purchase evidence and a clear location dossier enables the authorities to plan and execute judicially authorised searches on warehouses, markets and retail outlets. The most effective operations are those where the rights holder’s representative is available to assist in identifying counterfeit stock and with the chain of custody of seized goods. Engage customs and the authorities early rather than as an afterthought: a parallel civil injunction preserving the same goods reinforces the criminal seizure and prevents dissipation of evidence.

7. Remedies, damages, costs and enforcement of judgment

On a successful civil claim, the court can grant injunctive relief to stop the infringement, order the recall and destruction of infringing goods and the means of their production, and require an accounting. Damages under Law No. 6769 may be assessed on recognised bases, including the rights holder’s actual loss and lost profits, the profits the infringer made, or a reasonable royalty reflecting what the infringer would have paid for a licence. Expert valuation evidence is usually required to substantiate the quantum, which is why a strong damages case is built on documented sales volumes and market data.

Recoverable costs include attorneys’ fees allocated by the court in accordance with the applicable tariff, which is generally lower than the fees actually incurred. Where the defendant’s assets are at risk, provisional attachment can preserve the position. Once judgment is final, execution proceeds through the enforcement offices (icra daireleri), which carry out attachment, delivery and destruction. Foreign rights holders holding a Turkish judgment enforce it domestically through these offices; recognition and enforcement of a Turkish judgment abroad is a separate process governed by the relevant foreign jurisdiction and applicable treaties. Budget for execution as a distinct phase, a judgment is only as valuable as its enforcement.

10. Costs and fees

Official court fees, TÜRKPATENT fees and customs charges are set by the relevant authorities and are revised periodically (court and official fees are generally updated at the start of each year). Attorney fees are not fixed by statute but are subject to a minimum tariff published annually by the Union of Turkish Bar Associations, with actual fees varying by complexity. Because these figures change regularly and depend on the value and nature of the dispute, the table below indicates only the categories of cost to budget for; current amounts should be confirmed with local counsel before proceeding.

All amounts vary and should be confirmed with local counsel before budgeting; official tariffs are typically updated annually.

11. What changes in 2026, practice updates and a checklist for counsel

The substantive framework for trademark enforcement turkey, civil, criminal and administrative, remains codified in Law No. 6769. The practical changes to watch are procedural and administrative rather than a wholesale statutory overhaul.

• Non-use cancellation before TÜRKPATENT. The provision transferring jurisdiction over non-use cancellation to TÜRKPATENT took effect in January 2024; counsel should factor this administrative route into enforcement planning.
• Administrative guidance. TÜRKPATENT and the customs authorities periodically update procedural guidance; counsel should monitor official notices for changes affecting filings and customs coordination.
• Digital evidence. Courts continue to develop their approach to the admissibility of electronic evidence and to injunctive relief against online marketplaces; recent Court of Cassation decisions should be checked before relying on screenshots alone.
• Customs practice. Confirm current application and detention procedures directly with the Ministry of Trade, as operational details and forms are updated outside the statutory cycle.

Action items for counsel: verify the latest TÜRKPATENT guidance, review recent Yargıtay precedent on digital evidence and online injunctions, and confirm customs practice with the Ministry of Trade before filing.

12. Common pitfalls and tips from counsel

• Weak chain of custody. A sample without a documented purchase trail is vulnerable in both civil and criminal proceedings; record every step of acquisition and storage.
• Mis-identified claimant. Filing in the wrong name, a group entity rather than the registered proprietor, or a licensee without standing, invites dismissal; confirm title and recordals first.
• Delaying urgent relief. Waiting too long to seek an interim injunction undermines the urgency the court needs to see; move early with evidence ready.
• Ignoring the criminal route. Against deliberate counterfeiters, a criminal complaint and raids can achieve more, faster, than a civil suit alone.
• Relying solely on takedown notices. Platform takedowns address symptoms; combine them with substantive civil, criminal or administrative action to stop repeat offenders.

The practical takeaway: sample products and preserve electronic evidence at the outset, coordinate civil and criminal strategies so they reinforce each other, and engage customs before goods reach the market rather than after.

Conclusion

Effective trademark enforcement turkey rests on matching the right route, or combination of routes, to the commercial objective, and on moving with a prepared evidentiary file rather than after the fact. Civil litigation secures injunctions and damages, criminal complaints drive seizures and deterrence, and administrative action before TÜRKPATENT clears the register and underpins customs interdiction. The framework under Law No. 6769 remains broadly stable into 2026, but procedural practice on non-use cancellation, digital evidence, online injunctions and customs coordination continues to evolve, so verifying the latest TÜRKPATENT guidance and Yargıtay precedent before filing is essential. Brand owners who register early, preserve evidence rigorously and coordinate their civil, criminal and administrative strategies will find trademark enforcement turkey both practical and effective.
