Trademark Invalidity Actions in Türkiye: Grounds, Acquiescence and the Difference from Administrative Revocation
A registered trademark is not always safe. A defect that existed at the moment of registration can lead to the mark being declared invalid by court judgment. The invalidity action is the vehicle for raising that defect. The Industrial Property Code No. 6769 governs the grounds of invalidity, the persons entitled to sue, and the loss of rights through acquiescence. This article examines the invalidity regime and how it differs from the administrative revocation route.

Proof of Use in Turkish Trademark Oppositions: The Five-Year Test
Under Article 19/2 of the Turkish Industrial Property Code, an opponent whose trademark has been registered for more than five years must, upon the applicant's request, prove genuine use of that mark in Türkiye. Where proof fails, the opposition fails with it. This article examines how the proof-of-use mechanism works, what counts as genuine use, and how both sides should prepare for it.

Trademark Licence Agreements under Turkish Law: Exclusive and Non-Exclusive Licences Compared
A trademark licence is the principal tool for monetising a mark without parting with it. Yet licence relationships built without regard to the licensing provisions of the Industrial Property Code No. 6769 expose both licensor and licensee to serious risk. This article covers the types of licence, the written-form requirement, recordal with the registry and the licensee's standing to sue.

Bad-Faith Trademark Filings in Türkiye: The True Owner's Toolkit
Those who try to register someone else's mark, a sign learned through a business relationship, or a name known in the market are treated as bad-faith applicants under Turkish trademark law. The Industrial Property Code No. 6769 keeps both the opposition and the invalidity route open against them. This article examines the concept of bad faith, its typical patterns, and the legal tools available to the true owner.

Protection of Well-Known Trademarks in Türkiye: When Does Protection Cross Class Boundaries?
Trademark protection is, as a rule, confined to the goods and services covered by the registration. For well-known marks, the Industrial Property Code No. 6769 crosses that boundary through two distinct mechanisms. This article examines the protection of well-known marks within the meaning of the Paris Convention and the beyond-class protection tied to reputation acquired in Türkiye, and sets out the differences between the two.

This article covers the service invention and free invention distinction, the notification and claim mechanism, and the question of compensation.

Trademark Protection on E-Commerce Platforms: From Complaint Mechanisms to the Power of Registration
The centre of gravity of anti-counterfeiting has shifted from physical markets to e-commerce platforms. Platform complaint mechanisms can deliver fast results, but almost all of them require a registered trademark right to rely on. This article covers in-platform complaint procedures, the legal position of intermediary service providers, and the strategic value of registration in e-commerce.

The Priority Right: The Invisible Calendar of International Filing Strategy
A first filing in one country gives its owner a head start in every other country for a defined period. The priority right born of the Paris Convention lasts six months for trademarks and designs and twelve months for patents and utility models. Managed well, these periods form the backbone of a global protection strategy; missed, they cause losses that cannot be repaired. This article covers how priority works and how to use it strategically.

Trade Name versus Trademark in Türkiye: Two Registries, One Market
A trade name is registered with the trade registry, a trademark with the registry kept by the Turkish Patent and Trademark Office. Two separate registry systems operating side by side in the same market create a frequent zone of conflict: the company carrying a term in its trade name meets the business that registered the same term as a trademark. This article covers the differences between the two rights and the principles for resolving the conflict.

Preliminary Injunctions and Evidence Preservation in Turkish Trademark Infringement Litigation
Trademark infringement actions take time. The infringement, meanwhile, continues throughout the proceedings: counterfeit goods keep selling, and the mark's customer base keeps being misled. Two instruments available at the very start of the dispute therefore matter as much as the action itself. A preliminary injunction stops the infringement before judgment; evidence preservation secures proof that would otherwise disappear. This article examines the conditions, the deadlines and the practical strategy of both.

Generative AI tools are now in everyday commercial use for text, images, music and software. Their spread has surfaced a fundamental legal question: is an AI output a work at all, and if so, who is its author? The Turkish Copyright Act ties authorship to human creativity, which makes the protection of purely prompted output doubtful. And content that is not protected may be used freely by anyone, competitors included. This article examines the current framework and its practical consequences for companies.

The Quietest Way to Lose a Right: Renewal Calendars and Bulletin Watch
A trademark lost in court leaves a reasoned judgment in the file. A trademark lost to a missed renewal window leaves nothing at all. That is what portfolio administration is actually about: most rights are not lost in disputes, but on calendars nobody was watching.

Official Gazette Weekly Update — 28 September–4 October 2026: Annulment of the Phrase “Indefinitely” in Poverty Alimony, Real Estate Trade and the Distilled Spirit Drinks Communiqué
Resmî Gazete Haftalık Gelişmeler — 28.09–04.10.2026: Yoksulluk Nafakasında “Süresiz Olarak” İbaresinin İptali, Taşınmaz Ticareti ve Distile Alkollü İçkiler Tebliği
This legal update presents a selection of the Constitutional Court decisions, amending regulations and communiqués published in the Official Gazette issues Nos. 33384 to 33390 between 28 September 2026 and 4 October 2026. No duplicate issue was published between these dates. The update covers one annulment decision, four individual application decisions, three amendments to regulations and one communiqué.
01
Introduction
In the judicial section of the week, the Constitutional Court’s decision annulling the phrase “indefinitely” (“süresiz olarak”) in the first paragraph of Article 175 of the Turkish Civil Code (Law No. 4721) was published in the Official Gazette dated 30 September 2026. The annulment will enter into force nine months after the publication of the decision. In the same week, one individual application decision concerning freedom of expression and three concerning the right to a reasoned decision were published.
In the executive and administrative section, the Regulation on Real Estate Trade, the Regulation on the Notaries Law and the Regulation on Licensed Warehousing of Agricultural Products were amended, and the Turkish Food Codex Communiqué on Distilled Spirit Drinks (Communiqué No. 2026/18) was published. The Communiqué contains provisions on the use of geographical indications and distilled spirit drink category names in labelling and presentation. No instrument was identified in the indices of the issues covered by this update amending the legislation on industrial property, intellectual and artistic works, personal data protection, competition or broadcasting.
The Constitutional Court annulled the phrase “indefinitely” in Article 175 of the Turkish Civil Code, with effect nine months after publication; the Distilled Spirit Drinks Communiqué entered into force on 1 October 2026.

Decisions and Legislation of the Week
Constitutional Court: Annulment of the Phrase “Indefinitely” in Poverty Alimony
Decision Reference and the Annulled Provision
The Constitutional Court’s decision dated 4 June 2026, Docket No. 2025/156, Decision No. 2026/131 (E: 2025/156, K: 2026/131) was published in the Official Gazette dated 30 September 2026 and numbered 33386. The decision was rendered upon an application for constitutional review (objection procedure) lodged by the Antalya 12th Family Court in a divorce case. The provision under review is the phrase “indefinitely” in the first paragraph of Article 175 of Law No. 4721. The paragraph reads as follows: “The party who will fall into poverty as a result of divorce may, provided that their fault is not greater, claim maintenance indefinitely from the other party for their subsistence, in proportion to the other party’s financial means.”
The Court’s Reasoning
The Court stated that, in cases where poverty alimony is to be awarded in the form of periodic payments, the judge should be empowered to determine the duration of the alimony by taking into account factors such as the length of the marriage, the age, education and health of the spouse entitled to maintenance, and that spouse’s capacity to meet their economic needs by their own means, and that a definite and foreseeable framework should be established in this respect. The decision states that the criteria for the circumstances requiring alimony to be awarded indefinitely should be set out clearly and precisely in the provision. According to paragraph 32 of the decision, under the provision “granting the possibility to claim alimony indefinitely in all circumstances is incompatible with the State’s positive obligation arising from the individual’s right to protect and develop their material and spiritual existence.” The Court found the provision contrary to Articles 2, 5 and 17 of the Constitution.
Ruling and Date of Entry into Force
The annulment of the phrase was decided by majority vote, with Engin Yıldırım, Selahaddin Menteş and Kenan Yaşar dissenting. Yıldız Seferinoğlu concurred with the majority on different grounds. The Court considered the legal gap resulting from the annulment to be “of a nature that would harm the public interest” and decided unanimously that the annulment would enter into force nine months after the publication of the decision in the Official Gazette.
Dismissal over a Television Statement and Freedom of Expression
The Mehmet Güven decision of the First Section of the Constitutional Court dated 21 April 2026 (Application No. 2022/81264) was published in the Official Gazette dated 2 October 2026 and numbered 33388. The application concerns the allegation that the freedom of expression of the applicant, whose employment contract was terminated on account of statements made to a local television channel, had been violated. The applicant was employed with worker status at a metropolitan municipality company. The decision states that the regional court of appeal did not attempt to strike a balance between freedom of expression and the right to protection of honour and reputation, and “accepted, solely on the basis of an abstract assessment, that the statements in question constituted a valid reason for termination”. The Court unanimously held that freedom of expression, guaranteed under Article 26 of the Constitution, had been violated and that a copy of the decision be sent to the relevant court for retrial.
Three Decisions on the Right to a Reasoned Decision
Three decisions of the Second Section were published in the Official Gazette dated 29 September 2026 and numbered 33385. The Gülşah Kale decision dated 8 April 2026 (Application No. 2022/90210) concerns the failure, in a reinstatement action, to address substantial arguments capable of altering the outcome of the decision, despite the six-month seniority requirement having been met. The Refik Bayhan decision dated 9 April 2026 (Application No. 2022/44330) concerns the failure to address, in the decision, an argument affecting the outcome of an action brought by a partner who was the founding representative of a private company against the refusal of an application to open a special education institution. The Aydın Toksöz decision dated 8 April 2026 (Application No. 2022/104137) concerns criminal proceedings.
In all three applications, the Court held that the right to a reasoned decision, within the scope of the right to a fair trial guaranteed under Article 36 of the Constitution, had been violated and that a copy of the decision be sent to the relevant court for retrial. In all three decisions, the applicant was awarded litigation costs totalling TRY 40,664.10, consisting of TRY 664.10 in fees and TRY 40,000 in counsel’s fees. In the Refik Bayhan decision, the applicant’s compensation claims were dismissed.
Individual application decisions published during the week (Decision (App. No.) · OG date / issue · Right violated · Outcome)
Gülşah Kale (2022/90210) — 29 Sep 2026 / 33385 — Right to a reasoned decision (Art. 36) — Violation; retrial; TRY 40,664.10 litigation costs
Refik Bayhan (2022/44330) — 29 Sep 2026 / 33385 — Right to a reasoned decision (Art. 36) — Violation; retrial; compensation claims dismissed
Aydın Toksöz (2022/104137) — 29 Sep 2026 / 33385 — Right to a reasoned decision (Art. 36) — Violation; retrial; TRY 40,664.10 litigation costs
Mehmet Güven (2022/81264) — 2 Oct 2026 / 33388 — Freedom of expression (Art. 26) — Violation; retrial (unanimous)
Amendment to the Regulation on Real Estate Trade
The Ministry of Trade’s Regulation Amending the Regulation on Real Estate Trade was published in the Official Gazette dated 1 October 2026 and numbered 33387 and entered into force on the date of its publication. The amendment restructured the fifth paragraph of Additional Article 1 of the Regulation, which concerns the secure payment system, and replaced the date “1/7/2026” (1 July 2026) in the tenth paragraph of Provisional Article 1 with “1/12/2026” (1 December 2026).
The legislation provides: Under the new wording of the fifth paragraph of Additional Article 1, an integrator is authorised by the Ministry for the purposes of establishing, effectively operating and developing the secure payment system and producing statistical data and reports. The payment system is established and operated in accordance with a protocol signed between the relevant units of the Ministry and of the Ministry of Environment, Urbanisation and Climate Change and the integrator. The real estate sales to be excluded from the payment system, the requirement for a pilot implementation, the payment system usage fee and the method of sharing that fee are determined by this protocol.
The Ministry of Agriculture and Forestry’s Communiqué was published in the Official Gazette dated 1 October 2026 and numbered 33387 and entered into force on the date of its publication. The Communiqué repealed the Turkish Food Codex Communiqué on Distilled Spirit Drinks (Communiqué No. 2016/55), published in the Official Gazette dated 21 March 2017 and numbered 30014. Article 20 of the Communiqué states that the instrument was prepared within the framework of harmonisation with European Union legislation, taking into account Regulation (EU) 2019/787 of the European Parliament and of the Council. Beers produced from malt and wine from fresh grapes fall outside the scope of the Communiqué.
