What Is Trademark Opposition in Turkey: TPTO Process, Two‑month Deadline, Evidence and Appeals

Understanding what is trademark opposition in Turkey has become an increasingly strategic concern for brand owners, in-house counsel and IP practitioners operating in one of Europe’s largest consumer markets. Türkiye’s Industrial Property Law No. 6769 establishes a pre‑registration opposition system administered by the Turkish Patent and Trademark Office (TPTO, or Türk Patent ve Marka Kurumu), giving rights holders a critical two‑month window to challenge conflicting applications before they proceed to registration. With administrative revocation of trademarks now fully operational in 2026, the stakes around evidence‑of‑use, portfolio hygiene and tactical sequencing between opposition and cancellation proceedings have risen sharply.

This guide walks practitioners through every phase of the TPTO opposition procedure, from filing deadlines and grounds, through evidence preparation and defensive tactics, to appeal routes and the new revocation landscape.

Executive Summary: What This Guide Covers

• Definition. Trademark opposition in Turkey is a pre‑registration administrative proceeding before the TPTO, enabling any interested party to challenge a published trademark application on absolute or relative grounds under Industrial Property Law No. 6769.
• Two‑month deadline. The opposition window is strictly two months from the date of publication in the Official Trademark Bulletin, missing it forecloses this route entirely.
• TPTO process. A structured exchange of submissions between opposer and applicant, culminating in an administrative decision that can be appealed to the specialised IP courts.
• Evidence‑of‑use focus (2026 context). With administrative revocation proceedings now handled by the TPTO rather than exclusively by courts, proving genuine use of your earlier mark is more important than ever, both for sustaining an opposition and for defending your own registrations against non‑use challenges.
• Next steps. Practitioners should audit portfolios, compile use evidence proactively and seek qualified Turkish IP counsel to navigate the intersection of opposition, revocation and cancellation strategies. Use the Global Law Experts lawyer directory to connect with specialists in Turkey.

What Is Trademark Opposition in Turkey?

Trademark opposition in Turkey is a formal, pre‑registration proceeding in which a third party requests the TPTO to refuse a published trademark application. Unlike post‑registration invalidity actions, which target marks that have already been entered on the register, opposition intervenes before registration is granted, making it the most cost‑effective and timely mechanism for preventing a conflicting mark from securing rights.

The legal basis sits in Articles 17–19 of Industrial Property Law No. 6769 (Sınai Mülkiyet Kanunu), which entered into force on 10 January 2017, consolidating Türkiye’s trademark, patent and design legislation into a single statute. The Law is publicly accessible through the WIPO Lex database and the official TurkPatent website. It is important to distinguish opposition from two related but distinct procedures: post‑registration invalidation (brought before courts or, under specific grounds, the TPTO) and administrative revocation for non‑use, which as of 2026 can be filed directly with the TPTO. The opposition route remains the first line of defence for brand owners monitoring the Turkish trademark register.

For a broader overview of how to protect your intellectual property across borders, practitioners should consider how Turkey’s system fits within a wider international filing strategy.

Legal Framework and Key Definitions

Industrial Property Law No. 6769

Law No. 6769 governs all aspects of trademark prosecution in Türkiye, from application and examination through to opposition, registration, post‑registration proceedings and enforcement. Key articles for opposition practitioners include Article 5 (absolute grounds for refusal), Article 6 (relative grounds for refusal), Articles 17–19 (opposition procedure, deadlines and evidence), and Articles 26–27 (invalidity and revocation). The statute was published in the Resmi Gazete (Official Gazette) on 10 January 2017 and has been subject to subsequent regulatory instruments that operationalise specific provisions, including the administrative revocation mechanism.

Key definitions for practitioners

TPTO Opposition Procedure, Step by Step

The TPTO opposition procedure follows a structured sequence codified in Articles 17–19 of Law No. 6769 and the implementing Regulation on the Implementation of Industrial Property Law. Below is a step‑by‑step breakdown, followed by a timeline summary.

Publication and the opposition window

Once a trademark application passes the TPTO’s formal and absolute-grounds examination, it is published in the Official Trademark Bulletin (Resmi Marka Bülteni), available online through the TurkPatent website. The opposition deadline in Turkey is two months from this publication date. The deadline is calculated by reference to the calendar date: if the application is published on 1 March, the opposition must be filed by 1 May. If the final day falls on an official holiday or weekend, the deadline extends to the next business day. This two‑month period is non‑extendable.

Filing the opposition

The opposer must submit a written petition to the TPTO that includes: identification of the opposed application (number and mark), the grounds relied upon (citing the relevant articles of Law No. 6769), supporting arguments, and the prescribed opposition fee. A power of attorney is required where the opposition is filed through a trademark attorney or legal representative. All documentary evidence supporting the opposition should accompany the petition or be filed within the submission period specified by the TPTO. The opposition fee is payable to the TPTO and is published in the Office’s annual fee schedule, which is updated each year and available on the TurkPatent website.

Notice to applicant and applicant’s reply

Upon receiving a compliant opposition, the TPTO issues a notification to the applicant, transmitting the opposition petition and evidence. The applicant is given one month to submit a response. The applicant’s reply may include counter‑arguments, its own evidence (including evidence of coexistence in the market, consent letters or proof that the marks are not confusingly similar), and any procedural objections.

Evidence exchange and further submissions

Following the applicant’s response, the TPTO may, at its discretion, share the response with the opposer for further comment. In practice, a single round of exchange is most common, although complex cases (particularly those involving well‑known mark claims or extensive evidence‑of‑use arguments) may see additional rounds. Each party should ensure all evidence is filed within the periods specified by the TPTO, as late submissions risk being excluded from consideration.

TPTO decision and time to appeal

The TPTO’s Re‑examination and Evaluation Department renders a decision either upholding the opposition (and refusing the application in whole or in part) or rejecting the opposition (and permitting the application to proceed to registration). The losing party has two months from notification of the decision to file an appeal before the specialised Ankara IP Court (Ankara Fikri ve Sınai Haklar Mahkemesi).

Grounds for Trademark Opposition in Turkey, Practical Examples

Absolute grounds

Article 5 of Law No. 6769 sets out the absolute grounds for refusal, which any party (or the TPTO ex officio) may invoke. These include marks that lack distinctiveness, are generic or descriptive of the goods or services covered, consist exclusively of shapes dictated by the nature of the goods, or are deceptive as to the nature, quality or geographical origin of the goods or services. A practical example: opposing a cosmetics application for the word “NATURAL GLOW” on the basis that it is descriptive of the product’s intended effect falls squarely within absolute grounds.

Relative grounds

Article 6 addresses relative grounds, which require the opposer to hold an earlier right. The most common bases are:

• Identity or likelihood of confusion. The opposed mark is identical or similar to an earlier registered (or applied‑for) mark, and covers identical or similar goods/services, creating a likelihood of confusion among the relevant public. In the fashion sector, for instance, a new application for “ZARIA” in Class 25 (clothing) may be opposed by the owner of a registered “ZARA” mark in the same class.
• Well‑known marks. Under Article 6(4)–(5), the owner of a well‑known mark, whether registered in Turkey or not, may oppose an application even for dissimilar goods if the later mark would take unfair advantage of, or be detrimental to, the distinctive character or repute of the well‑known mark.
• Earlier trade names and other commercial identifiers. Rights holders relying on a registered trade name, company name, or domain name used in trade in Turkey may oppose a conflicting trademark application.
• Prior use. A party that has used a mark in Turkey prior to the filing or priority date of the opposed application, without necessarily registering it, may invoke prior use as an opposition ground, provided it can demonstrate genuine and continuous commercial use.

When drafting grounds for trademark opposition, practitioners should cite the specific sub‑paragraphs of Article 5 or Article 6 relied upon, identify the earlier right with precision (registration number, class, date), and link the factual arguments directly to the legal test. Vague or overly broad petitions risk diluting the strongest arguments.

Evidence‑of‑Use in Türkiye: The Practitioner’s Focus for 2026

Evidence of genuine use has always been central to trademark opposition in Turkey, but the 2026 landscape makes it mission‑critical. With administrative revocation for non‑use now firmly within the TPTO’s jurisdiction, every brand owner, whether opposing a third‑party application or defending its own registrations, must maintain robust use evidence at all times.

Proofs that work before the TPTO

The TPTO evaluates evidence holistically, looking for materials that demonstrate genuine commercial exploitation of the mark in connection with the registered goods or services within Türkiye. The following document types have proven effective in TPTO proceedings and in subsequent judicial review:

• Commercial invoices and sales records. Invoices bearing the mark, showing sales to Turkish customers, including quantities, dates and product descriptions.
• Customs documents. Import/export records evidencing goods bearing the mark entering or leaving Turkey, particularly relevant for international brand owners.
• Advertising and promotional materials. Print advertisements, digital campaign screenshots (with metadata showing dates), catalogues, lookbooks (especially in fashion and cosmetics), social media campaigns targeted at Turkish consumers and point‑of‑sale materials.
• Product packaging and labels. Photographs or samples of packaging, hang tags, labels, and, for cosmetics, safety data sheets or product information files that reference the trademark.
• Website and e‑commerce evidence. Screenshots from Turkish‑language or Turkey‑targeted websites showing the mark in use, including Wayback Machine archives with timestamps.
• Affidavits and sworn declarations. Statements from company officers or distributors attesting to the nature, extent and duration of use, ideally supported by underlying documentary evidence.
• Licence agreements. Executed licence or distribution agreements demonstrating authorised use of the mark in Turkey.

Acceptable date ranges and tying evidence to goods and services

Evidence must demonstrate use within a relevant timeframe. In opposition proceedings based on relative grounds, the TPTO will assess whether the earlier mark has been put to genuine use during the five‑year period preceding the publication date of the opposed application (where the earlier mark’s registration is older than five years). Each piece of evidence should be clearly tied to the specific goods or services for which protection is claimed, a common error is submitting invoices for “clothing” when the opposition relies on a registration covering “footwear” without demonstrating the connection.

Evidence‑of‑use checklist

Practitioners preparing a trademark opposition in Turkey or defending against a non‑use challenge should compile the following as a standing evidence file:

• Dated invoices. Minimum three years of continuous sales records bearing the mark and showing Turkish customers.
• Advertising expenditure records. Budget summaries and media placement confirmations for Turkish campaigns.
• Product images. High‑resolution photographs showing the mark as used on actual goods or packaging.
• Distribution agreements. Copies of Turkish distribution or retail agreements in force during the relevant period.
• Market reports or surveys. Independent reports demonstrating brand awareness or market share in Turkey (if available).
• Screenshots with timestamps. Web presence evidence captured with visible dates, ideally through notarised screenshots or Wayback Machine records.
• Sworn declaration. A concise, factual declaration from a person with knowledge of the business operations, summarising the mark’s use in Turkey.

Common pitfalls and overcoming the non‑use defence

Applicants frequently invoke the non‑use defence (Article 19(2) of Law No. 6769), asserting that the opposer’s earlier mark has not been genuinely used for five consecutive years. The most common pitfalls for opposers include: submitting evidence that shows the mark used only outside Turkey; providing undated materials; presenting use evidence for goods or services not covered by the registration relied upon; and relying solely on an affidavit without corroborating documents. To overcome these risks, practitioners should tie every document to a date, a Turkish territory connection and the specific Nice Classification of goods or services at issue.

Interplay With Administrative Revocation and Cancellation (2026 Update)

The most significant procedural development affecting trademark opposition in Turkey in 2026 is the full operationalisation of administrative revocation before the TPTO. Previously, revocation of a trademark for non‑use could only be pursued through the courts, a slower and more expensive process. Under the current regime, published in the Resmi Gazete and implemented via TPTO regulatory instruments, any person may file an administrative revocation request directly with the TPTO on the ground that a registered mark has not been put to genuine use in Turkey for a continuous period of five years.

This creates new tactical possibilities. An applicant facing an opposition based on an earlier mark that the applicant believes is not in genuine use can now file a parallel administrative revocation request with the TPTO, seeking to remove the earlier mark from the register. Conversely, an opposer must ensure its own registrations are actively used and evidenced, because the applicant, or any third party, can target those registrations for revocation. Industry observers expect this dual‑track environment to accelerate portfolio audits across sectors, particularly in FMCG, fashion and cosmetics, where large portfolios may include dormant or defensive registrations.

From a tactical sequencing perspective, practitioners should consider whether to file an opposition immediately (to preserve the two‑month deadline) and simultaneously initiate a revocation action against blocking marks on the register, or, alternatively, to pursue revocation first and re‑file or amend the application once the blocking mark is removed. The optimal approach depends on the strength of use evidence, budget constraints and the commercial urgency of securing registration.

Responding to an Opposition and Defensive Tactics

Structuring the response

When an applicant receives notice of an opposition, the response should address each ground raised by the opposer, marshalling evidence and legal argument point by point. The response period is one month from notification. Applicants may also consider narrowing their specification of goods or services, voluntarily limiting the scope of the application to remove overlap with the opposer’s earlier rights, which may resolve the conflict without a contested decision.

Invoking the non‑use defence

As noted above, if the opposer’s earlier registration has been on the register for more than five years, the applicant may request proof that the mark has been put to genuine use in Turkey during the preceding five‑year period. This procedural tool shifts the burden to the opposer and, if the opposer cannot produce sufficient evidence, the opposition fails. It is a powerful defensive tactic that should be invoked as a matter of course where applicable.

Settlement and coexistence agreements

Parties may resolve an opposition through negotiation at any stage. Coexistence agreements, in which both parties agree to concurrent use of their respective marks, often with limitations on goods, services, territories or trade channels, are recognised in Turkish practice. If a settlement is reached, the opposer should withdraw the opposition formally before the TPTO. Practitioners should ensure any coexistence agreement is documented in writing, covers all relevant jurisdictions and specifies enforcement mechanisms.

Appeals, Timelines and Forum: TPTO to Courts

A party dissatisfied with the TPTO’s opposition decision may appeal to the specialised Ankara IP Court within two months of receiving notification of the decision. The appeal is a de novo review, the court examines both the facts and the law afresh and may receive new evidence. Decisions of the Ankara IP Court are, in turn, subject to appeal before the regional court of appeal (Bölge Adliye Mahkemesi) and ultimately the Court of Cassation (Yargıtay).

For matters progressing through the full judicial chain, industry observers expect total resolution times of two to four years from the initial TPTO filing to a final Yargıtay ruling, although many disputes settle before reaching the Court of Cassation. Court fees and legal costs increase at each stage, and practitioners should factor these into the cost‑benefit analysis before pursuing an appeal. Additional guidance on dispute resolution frameworks is available in the international intellectual property guide.

Practical Checklist: Deciding Whether to Oppose

Before committing resources to an opposition, practitioners should evaluate the strategic factors in the following decision matrix:

Conclusion

Trademark opposition in Turkey is a procedurally disciplined, evidence‑intensive mechanism that rewards preparation and strategic clarity. The two‑month opposition deadline from publication is absolute, making trademark‑watch services and rapid decision‑making essential for brand protection. In the 2026 environment, where administrative revocation operates alongside the opposition system, practitioners must maintain standing use evidence and coordinate opposition strategy with broader portfolio management. Any party considering filing or responding to a trademark opposition in Turkey should consult experienced IP counsel, use the Global Law Experts lawyer directory to find qualified practitioners in Türkiye.
