Devin Patent is a trademark and patent attorneyship office in Istanbul. Searches, filings, oppositions, renewals, recordals and portfolio administration before TÜRKPATENT, EUIPO, WIPO and the EPO — one office for every stage, with each step weighed against the statute and the case law behind it.
Every Filing Is A Document Someone Will Later Read Against You.
Devin Patent is a trademark and patent attorneyship office based in Istanbul, acting for Turkish and international rights holders. Registered attorneys handle every stage of a right — searches, applications, oppositions, YİDK proceedings, renewals, recordals and portfolio administration before TÜRKPATENT, EUIPO, WIPO and the EPO.
What separates the office from most of the market is where its people come from. Our attorneys have legal training, and a specification, a claim set or an opposition brief is drafted the way a document is drafted when you expect it to be tested later — against the statute, against examination practice, and against the case law that sits behind both.
That shows up in ordinary decisions. Which classes to file and how to word them. How broadly to draft a claim before it stops being defensible. Whether to build evidence of use in the first year rather than assemble it under deadline pressure in the fifth. Whether a consent letter is worth asking for, and what it should say.
Portfolios are run on a single calendar. Opposition windows, renewal dates and annuity deadlines are docketed centrally, audits identify dormant rights and gaps in class coverage, and clients receive scheduled status reporting rather than an invoice and a certificate.
Court proceedings, compensation claims, criminal complaints, contract drafting and advisory work are not carried out here. They are handled by our law firm, Devin Law & IP, and a file moves between the two offices without losing its history.
Every file is handled by registered trademark attorneys who also hold a legal education; patent files are prepared together with patent attorneys, and the European route with European patent attorneys. Examination decisions are read against the statute and the case law behind them rather than accepted as administrative outcomes.
Searched Before It Is Filed
Nothing goes to the register before it has been searched. Availability, identity and prior art searches are run first, and where the result is negative we say so plainly instead of filing an application that will not survive examination.
One Calendar, Nothing Missed
Opposition windows, renewal dates, annuities and national phase deadlines are docketed centrally with layered reminders. Deadline discipline is the single most valuable thing an attorneyship office can offer, and we treat it that way.
Filed Abroad Under One Roof
Madrid, PCT, the European patent route, the Hague System, EUIPO and direct national filings are coordinated from Istanbul through a vetted associate network, so strategy, timing and budget stay consistent across every jurisdiction.
A Clear Route To The Courtroom
When a matter has to leave the register and go to court, it moves to Devin Law & IP with the full prosecution history behind it. Nothing is rebuilt from scratch and nothing is lost in the handover.

Devin Patent — Istanbul
About Us
A trademark and patent attorneyship office built on one idea: that a registration is a document which will one day be read against you, and should be drafted accordingly.
Who We Are
An attorneyship office run with the discipline of a legal practice.
Devin Patent carries more than 15 years of combined experience from its founders and solution partners. The office is built around registered trademark attorneys who also hold legal training — a combination that is still uncommon in the Turkish market and that shapes how every file is prepared. Patent and European patent files are prepared together with the patent attorneys among our solution partners.
We act for exporters, manufacturers, technology companies, producer associations, universities and individual inventors — portfolios ranging from a single national trademark to hundreds of rights spread across TÜRKPATENT, EUIPO, WIPO and the EPO. Files are grouped by right rather than by client size, so a small portfolio receives the same docketing discipline as a large one.
Work is reported, not just done. Clients receive scheduled status reports, renewal calendars and portfolio audits that identify dormant rights, duplicate filings and gaps in class coverage. Where a filing strategy carries risk, we set it out in writing before the application is made rather than after the refusal arrives.
Court proceedings, compensation and criminal actions, contract drafting and advisory work fall outside the scope of an attorneyship office. Those matters are carried out by our law firm, Devin Law & IP, which shares the same Istanbul team and the same recognition in international directories — so a file that has to be litigated arrives there with its full prosecution history intact.
Registered trademark attorneys who also hold a legal education, working with patent attorneys on patent files. Office actions, refusals and opposition decisions are read against the statute and the case law behind them.
Searched Before It Is Filed
Availability, identity and prior art searches come first. Where the result is negative we say so plainly rather than filing an application that will not survive examination.
One Calendar, Nothing Missed
Opposition windows, renewals, annuities and national phase deadlines are docketed centrally with layered reminders and scheduled reporting to the client.

Playing Music from a Subscription App on Business Premises and Criminal Liability: The Decision of the 7th Criminal Chamber of the Court of Cassation of 5 May 2026
This article examines the decision of the 7th Criminal Chamber of the Court of Cassation dated 5 May 2026 (Docket No. 2025/4040, Decision No. 2026/5401), which held that playing music in a café through a music app paid for by a monthly subscription constitutes the offence set out in Article 71(1) of Law No. 5846 on Intellectual and Artistic Works (the “LIAW”). The Chamber rejected the operator's defence that paying the subscription fee also covered the copyright royalties, stated that the case law on the absence of intent in radio and television broadcasts cannot be applied to subscription apps, and upheld the conviction by majority. The dissenting opinion concerns the manner in which the evidence was obtained, not the merits. The article discusses the reasoning of the decision, the line of case law on which it relies and its consequences for businesses.

Undeclared Goods on Board: Conviction and Acquittal Criteria in Smuggling Cases
This article has been prepared with a view to setting out, on the basis of decisions of the Court of Cassation, the criteria that determine the distinction between conviction and acquittal in smuggling cases concerning undeclared cigarettes, alcoholic beverages and fuel found on board ships in Turkish ports and territorial waters. The article first addresses the relationship between the smuggling offence and the sanction applied and tax assessed by the customs administration, together with the distinction between no declaration, under-declaration and over-declaration, and then examines the facts that are decisive in the decisions with regard to cigarettes and alcohol and to fuel, the personal liability of the master, the chief engineer and crew members, the rules on attempt, effective repentance and procedure, and the measures concerning the ship.

Acquiescence in Trade Mark Law: Different Rules for Invalidity and Infringement
This article has been prepared with a view to setting out the respects in which loss of rights through acquiescence in trade mark law differs as between invalidity actions and trade mark infringement actions. The article first describes the decisions of the 11th Civil Chamber of the Court of Cassation on the starting point of the five-year period in invalidity actions and the divergence between those decisions, together with its most recent decision, the decision of the 11th Civil Chamber of the Court of Cassation dated 4 June 2026, E. 2026/3054, K. 2026/3267. It then examines the criteria applicable in infringement actions and shows that even where loss of rights through acquiescence is not accepted in an invalidity action, the same silence may have consequences in an infringement action.

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.

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.

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.

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.

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.
Geographical Indications and Labelling
Under the second paragraph of Article 6 of the Communiqué, products registered under a geographical indication or a traditional product name are placed on the market under a product name not defined in ANNEX-1, provided that they comply with the specified product characteristics and do not contravene the provisions of the horizontal food codex.
The legislation provides: Under subparagraph (c) of the first paragraph of Article 15 of the Communiqué, no term or visual such as “similar”, “type”, “style”, “like”, “in the manner produced there”, “patent”, “aroma” or the like may be used in the labelling and presentation of a product in a manner that refers to the spirit drink category names listed in ANNEX-1, geographical indications, or internationally recognised category and cocktail names. Under subparagraph (h) of the same paragraph, the distilled spirit drink categories listed in ANNEX-1 and the geographical indications for distilled spirit drinks may not be used to describe or present any beverage other than distilled spirit drinks.
Compliance Periods and Sanctions
Under Provisional Article 1, food business operators operating before the date of publication of the Communiqué must comply with its provisions by 1 July 2027. Until they achieve compliance, these operators must comply with the provisions of the repealed Communiqué. Products placed on the market, or for which official import controls were completed, before the date of publication may remain on the market for eighteen months from the date of publication. Administrative sanctions are imposed on those acting in breach of the Communiqué under the relevant articles of Law No. 5996 on Veterinary Services, Plant Health, Food and Feed.
