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.
Filed Abroad Under One Roof
Madrid, PCT, the European patent route, the Hague System, EUIPO and direct national filings coordinated from Istanbul through a vetted associate network.

Articles and commentary from our team. Trademark, patent, design, domain name and geographical indication pieces are the work of this office. Data protection, media, corporate and regulatory subjects fall within the practice areas of Devin Law & IP and are published jointly.

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. 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.

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.

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.

The deadline for joint stock and limited liability companies to raise their capital to the new minimum amounts was extended to 31 December 2027; in Muhammet Babur the Constitutional Court found a right-to-property violation.
01
Introduction
In the executive and administrative section of the week, two instruments of the Ministry of Trade were published. By the Communiqué published in the Official Gazette dated 17 October 2026, the period prescribed for joint stock and limited liability companies to increase their capital to the new minimum amounts provided for in the Turkish Commercial Code No. 6102 was extended until 31 December 2027 (31/12/2027). By the amending Regulation published in the Official Gazette dated 15 October 2026, Article 12/B of the Regulation on the Principles and Rules to be Applied in Retail Trade, concerning sales by instalments, was redrafted.
The Official Gazette dated 16 October 2026 published the resolution of the Grand National Assembly of Türkiye on the election held for the two vacant memberships of the Personal Data Protection Board, the Machinery Safety Regulation (2023/1230/EU) and the Communiqué amending the Public Procurement General Communiqué. The judicial section of the same issue contained the Muhammet Babur decision, in which the First Section of the Constitutional Court held that the right to property had been violated on account of the imposition of an administrative sanction by the Advertisement Board on the basis that a sale transaction was deemed an unfair commercial practice. The other issues of the week published the Regulation on Geographical Data Permits and the Regulation amending the Regulation on Technology Transfer Offices of Higher Education Institutions. No instrument was identified in the indices of the issues covered by this update amending the legislation on industrial property, intellectual and artistic works or competition.

The Ministry’s Powers over Instalment Sales in Retail Trade
The Ministry of Trade’s Regulation Amending the Regulation on the Principles and Rules to be Applied in Retail Trade was published in the Official Gazette dated 15 October 2026 and numbered 33401 and entered into force on the date of its publication.

The Constitutional Court’s Muhammet Babur Decision on an Advertisement Board Fine
The Muhammet Babur decision of the First Section of the Constitutional Court dated 6 May 2026 (Application No. 2021/24689) was published in the Official Gazette dated 16 October 2026 and numbered 33402. The application concerns the allegation that the right to property was violated on account of the imposition of an administrative sanction on the basis that a sale transaction was deemed an unfair commercial practice. According to the decision, the applicant is the owner of a business selling through an internet platform. Following an inspection carried out on 25 March 2020 by the Provincial Directorate of Trade of the Konya Governorship, the commercial practice directed at consumers in relation to the product in question was made the subject of an examination by the Presidency of the Advertisement Board. At its meeting of 14 April 2020, the Advertisement Board concluded that the applicant, contrary to the requirements of professional diligence, had increased the price of the product outside the normal functioning of the market mechanism and in a manner adversely affecting consumers’ purchasing behaviour, by taking advantage of the negative effect created by the COVID-19 pandemic on consumers; it decided to impose an administrative fine of TRY 104,781 pursuant to subparagraph (e) of the twelfth paragraph of Article 77 of Law No. 6502 on the Protection of Consumers and to order the cessation of the said commercial practice. The action brought by the applicant before the Ankara 10th Administrative Court seeking the annulment of the administrative sanction was dismissed by a decision dated 12 November 2020; the 9th Administrative Chamber of the Ankara Regional Administrative Court dismissed the appeal by its decision dated 7 April 2021.
In its decision, the Constitutional Court stated that the applicant had set out in detail, also indicating the amounts, the cost difference between the sales made through the e-commerce site and the sales carried out under physical conditions, had argued that the price increase forming the basis of the administrative sanction did not constitute an unfair commercial practice, and had requested that an expert report be obtained if necessary; however, the judicial authorities had not addressed this claim, which was capable of altering the outcome of the dispute. The decision further stated that, in addition to the administrative fine, the cessation of the commercial practice had also been ordered against the applicant and that, although the relevant provision states that this sanction may be applied where deemed necessary, no assessment whatsoever was made as to why the cessation sanction was deemed necessary in the specific case. Concluding that the procedural safeguards necessary for the protection of the right to property had not been afforded in the specific case and that the interference was not proportionate, the Court unanimously held on 6 May 2026 that the right to property guaranteed under Article 35 of the Constitution had been violated, that a copy of the decision be sent to the Ankara 10th Administrative Court (E.2020/944, K.2020/1662) for retrial, that the claim for compensation be rejected, and that litigation costs of TRY 40,487.60 be paid to the applicant.

Other Individual Application Decisions of the Constitutional Court
Two further individual application decisions of the First Section of the Constitutional Court were published in the Official Gazette dated 16 October 2026. The Olcay Özçelik decision dated 4 March 2026 (Application No. 2024/31038) concerns the allegation that the right to liberty and security of person was violated on account of the unlawfulness of detention, and the Osman Gökmen decision dated 6 May 2026 (Application No. 2022/11105) concerns the allegation that the right to a reasoned decision was violated on account of the failure to address, in proceedings relating to an occupational accident, substantial claims capable of altering the outcome of the decision. The operative parts of these two decisions are not examined in this update. The Official Gazettes dated 15 and 16 October 2026 also published sixty-three decisions of the Constitutional Court dated 26 March 2026, Nos. K: 2026/1 to K: 2026/63, concerning the financial audit of political parties.

Regulation on Geographical Data Permits
The Regulation on Geographical Data Permits of the Ministry of Environment, Urbanisation and Climate Change was published in the Official Gazette dated 14 October 2026 and numbered 33400 and entered into force on the date of its publication. Under Article 1 of the Regulation, its purpose is to determine the procedures and principles regarding the permits to be granted by the Ministry within the scope of the commercial activities of natural persons, private law legal entities, foreign natural persons and foreign legal entities in collecting, producing, sharing or selling the geographical data falling within the National Geographical Data Responsibility Matrix, and regarding the sharing of geographical data with the Ministry within the scope of disaster and emergency management. The Regulation was prepared on the basis of Article 1 of Law No. 7221 and Presidential Decree No. 49 on Geographical Information Systems.
The Legislation Provides
Under Article 10 of the Regulation, the period of validity of the permit certificate is determined, at the request of the permit holder and with the approval of the Ministry, as not less than one year and not more than five years; where the title of the legal entity or its shareholders change, the change is notified to the Ministry through the system within fifteen days. Under Article 15 of the Regulation, where it is established that a geographical data permit has not been obtained, the operator of the activity is granted a period of fifteen days from the date of notification to apply for a permit; natural persons who are Turkish citizens and private law legal entities that do not apply for a permit within the period granted are subject to an administrative fine in the amount of the highest one-year permit fee for the year in which the finding was made, and foreign natural and legal persons to an administrative fine in the amount of twice the one-year permit fee. Where the administrative fine is paid within the payment period, a reduction of 25% is applied to the fine.

Conclusion
In the week of 12 October 2026 – 18 October 2026, by the Ministry of Trade’s Communiqué, the period prescribed for joint stock and limited liability companies to increase their capital to the new minimum amounts was extended until 31 December 2027 (31/12/2027). Article 12/B of the Regulation on the Principles and Rules to be Applied in Retail Trade was amended, conferring on the Ministry the authority to determine instalment periods and to introduce additional restrictions in sales of goods and services by instalments other than housing sales. By Resolution No. 1513 of the Grand National Assembly of Türkiye, Recep Keskin and Cennet Alas Şekerbay were elected to the two vacant memberships of the Personal Data Protection Board.
The Machinery Safety Regulation (2023/1230/EU) was published; the former Machinery Safety Regulation (2006/42/EC) was repealed, and the provisions of the new Regulation other than those enumerated are arranged to enter into force on 20 January 2027 (20/1/2027). The phrases “TRY 5,000” in the Public Procurement General Communiqué were replaced with “TRY 50,000”. The Constitutional Court held that the right to property had been violated on account of the failure to address the claims in the action brought against the administrative fine and cessation order imposed by the Advertisement Board for an unfair commercial practice, and sent the file to the Ankara 10th Administrative Court for retrial. The Regulation on Geographical Data Permits provides for an administrative fine for activity carried out without a permit; the Regulation on Technology Transfer Offices of Higher Education Institutions now sets out the duty of technology transfer offices to establish and operate production facilities.
