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.

Advertising Board Decisions — Meeting No. 367: Right of Withdrawal, Comparative Claims and Health Connotations in Product Names
Key takeaways for brand owners from Meeting No. 367: unfair advantage taken of a public institution's logo and reputation, the burden of proof attached to superiority claims such as 'the best', 'leader' and 'No 1', and a product name treated as a health claim in its own right. The note traces how the Board's scrutiny of promotional practice now extends from product naming and packaging to sponsored content.

Advertising Board Decisions — Meeting No. 368: Sanctions for Repeated Infringements, Interface Design and Superiority Claims
For brand owners, Meeting No. 368 confirms that superlatives such as 'the most' and 'number one', influencer posts included, may only be used where substantiated by independent test reports. Decisions on the uncertified use of 'halal certified' and on origin-flavoured claims such as 'Belgium's Most Loved Chocolate' show that the use of trademarks, certificates and geographical references in advertising calls for careful planning.
Uğurcan Tekin · İnci Özçilsal · Beyza Erdemir5 September 2026
Meeting No. 369 carries significant signals for brand owners: the 'Ezine Cheese' decision confirms that a name registered as a geographical indication cannot be used on non-conforming products, while general superiority expressions such as 'the best' remain firmly tied to the burden of proof. With marketplace sellers and retailers held liable for the promotions on their own store pages, responsibility for branded-product advertising now runs through the entire supply chain.

The note draws practical lessons on the use of brand elements in promotions.

For brand owners, the decisions offer guidance on presenting campaign conditions together with the principal claim, on the display of consumer reviews, and on the individual liability of marketplace sellers for their own listings.

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.

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.

Geographical Indications/Insights
A Geographical Indication Is Not Property — It Is an Obligation
Applications for geographical indications are often prepared with the instincts of trademark practice: secure the name, keep the file, control who uses it. Almost none of those instincts transfer. The Third Book of the Industrial Property Code No. 6769, Articles 33 to 54, builds a collective regime in which the registrant holds the name on behalf of a production community rather than against it, and in which the obligations begin rather than end on the day of registration.
01
Two Categories, One Distinguishing Question
Article 34(1) defines a geographical indication as a sign identifying a product that has become identified with the region, area, locality or country of its origin by reason of a distinctive quality, reputation or other characteristic. It then divides the concept in two.
A designation of origin under Article 34(1)(a) covers products originating in a defined locality, region or, in exceptional cases, a country, whose whole or essential characteristics derive from the natural and human factors particular to that geographical area, and whose production, processing and other operations all take place within its boundaries. A geographical sign of source under Article 34(1)(b) covers products originating in a defined locality, region or country which are identified with that area by reason of a distinctive quality, reputation or other characteristic, and of whose production, processing and other operations at least one takes place within the area.
The distinguishing question is therefore not how strong the connection is but how much of the process happens inside the boundary. All of it, and the file is a designation of origin; at least one stage, and it is a sign of source. Article 34(2) adds that traditional names in everyday use which contain no geographical name may also qualify as either.
Article 34(3) sets out a third and separate category. A traditional speciality name falls outside both of the above and must be shown to have been used traditionally for at least thirty years in the relevant market to describe the product, and to satisfy at least one of two conditions: that it derives from a traditional method of production or processing or from a traditional composition, or that it is produced from traditional raw materials or ingredients.
The dividing line is procedural, not qualitative: all stages inside the boundary, or at least one.
02
Who May Apply — and the One Exception for a Single Producer
Article 36(1) restricts the right to apply to producer groups; public institutions and professional bodies of a public character connected with the product or the geographical area; associations, foundations and cooperatives working in the public interest or authorised to protect the economic interests of their members; and, where a product has a single producer, that producer, on condition that it proves the fact.
The last of those is the exception rather than the route. Article 37(1)(b) makes the proof of sole production a mandatory element of the application, and Article 36(2) defines a producer group as an association of producers of the same product regardless of its legal form or composition — which means an unincorporated group of producers may apply while a single company generally may not.
03
The Application Is a Specification, and the Specification Includes Its Own Audit
Article 37(1) lists what the file must contain: the name and category of the sign with evidence that it meets the definition; a description of the product with the technical evidence of its physical, chemical, microbiological and sensory characteristics; documents defining the boundaries of the geographical area; the method of production together with any local techniques and practices; evidence of the link between the product's quality, reputation or other characteristics and that area; the historical background of the product in the area; the manner of use, including labelling and packaging; and — the element most often underestimated — documents setting out in detail the form of inspection in accordance with Article 49.
That last requirement is not an annexe. The applicant designs the inspection regime, names the body that will carry it out, and lives with both after registration.
04
Article 49: The Duty That Starts at Registration
Article 49(1) defines inspection as covering all activities directed at verifying that use of the registered indication conforms to the characteristics stated in the registration, at the stages of production, offering for sale or distribution, or while the product is on the market. Article 49(2) provides that the inspection is carried out by the inspection body named in the application and whose competence has been approved by the Office, and that any change to the recorded body requires the Office's approval.
Article 49(3) is the operative obligation: inspection reports are submitted to the Office annually from the date the registration was published in the Bulletin, and where there is a complaint the Office may require a report to be submitted before it falls due. Article 49(4) provides that where the examination of a report reveals a deficiency, the registrant is notified and given six months to remedy it, and that if the deficiency is not remedied within that period or the inspection is found not to have been carried out properly, Article 43 applies.
Article 49(5) allows the registrant to recover the cost of inspection from those inspected. Article 49(7) preserves the separate regimes of Law No. 5996 on veterinary services, plant health, food and feed and of other legislation — the Article 49 inspection sits alongside, not instead of, ordinary food safety supervision.
“There is no statutory inspection frequency. The frequency is whatever the specification says it is — which means the applicant sets the standard it will be measured against for the life of the registration.”
05
What Losing the File Actually Looks Like
Article 43 is the provision that makes the regime unlike anything in trademark practice. Where a court decides, or the Office determines of its own motion, that the registrant no longer satisfies the conditions of Articles 36 and 49, the decision or determination is published in the Bulletin. Within three months of that publication, any party meeting the conditions of Article 36 may request a change in the application or registration records. Where no request is made, or none is found suitable, the right lapses; where there are several, the Office accepts the most appropriate.
The sequence deserves attention. A registrant that stops carrying out its inspection duties does not simply lose the protection — it is put at risk of losing the file to a different producer group that is willing to run it. The registration survives; the custodian changes.
The judicial route runs in parallel. Article 50 allows any person with an interest to seek invalidity from the court on three grounds: that the registration fails to meet the conditions of Articles 33, 34, 35, 37 or 39; that it was not made by a person entitled under Article 36; or that the inspection has not been carried out in the manner required by Article 49. The action is brought against the person recorded as registrant, and Article 50(3) provides expressly that the Office is not joined as a party.
06
Protection Without Exclusivity
Article 44(1) provides that protection is obtained through registration. Article 44(2) lists what may be prevented: commercial use, direct or indirect, of the indication or of the emblem required under Article 46 in a way that exploits the reputation of the indication where the product does not carry its characteristics; misleading use or imitation on a product which lacks those characteristics or which evokes the indication, even where the true origin or nature is stated or where terms such as style, type, kind, method or as produced in are used, and even where the name has been translated into another language; misleading statements on packaging, promotional material or documents; and misleading use of the emblem.
The evocation concept familiar from European practice is present in the Turkish text through that second limb and through Article 53(1)(b), which treats misuse, imitation or use evoking the indication as infringement even where the origin is stated or the name is translated. It is not set out under a separate heading, but the substance is there.
Against that stands Article 44(7): the registration of a geographical indication confers no exclusive right on the registrant. Anyone who complies with the conditions recorded in the register may use the name. Article 46(2) makes the emblem mandatory for geographical indications, to be used together with the registered sign on the product or its packaging; Article 46(3) provides for display at the premises where the nature of the product does not permit it; and Article 46(4) provides that use of a traditional speciality name without the emblem falls outside the Code — so for that category the emblem is not compulsory, but use without it is unprotected.
07
Why It Cannot Be Sold
Article 148(1) states that rights in geographical indications and traditional speciality names may not be the subject of licence, assignment, inheritance, attachment or similar legal transactions, and may not be given as security. The exclusion is absolute and it follows from the structure described above. A right that confers no exclusivity on its holder, that is exercised by every producer meeting the specification, and that can be transferred by the Office to a different custodian under Article 43 is not an asset capable of being traded. The registrant is a steward, and stewardship is not alienable.
For a commercial adviser the consequence is practical. A geographical indication does not appear on a balance sheet, cannot be pledged in a financing, and does not pass in a share transfer. Where a producer group is restructured, what has to be preserved is its continuing capacity to meet Articles 36 and 49 — not the ownership of a name.
08
The European Route Has Changed Twice in Two Years
Regulation (EU) 2024/1143 of 11 April 2024, published on 23 April 2024 and in force since 13 May 2024, replaced Regulation (EU) No 1151/2012 and brought wine, spirit drinks and agricultural products under a single geographical indications framework. Separately, Regulation (EU) 2023/2411 established a regime for craft and industrial products, applicable since 1 December 2025 — which opens a European route for Turkish craft indications that did not previously exist.
The Turkish presence in the EU register has grown quickly on the back of a deliberate programme: from eight registered Turkish geographical indications in January 2023 to forty-six by August 2026, with a substantial pipeline behind them. Domestically the register passed 1,881 registered products, with 66 added in the first half of 2026 alone.
One caution for anyone preparing a European file: TÜRKPATENT's published guidance on the EU application procedure still refers in places to Regulation No 1151/2012 and Regulation No 668/2014, both superseded. The Office published a new EU application guide on 27 January 2026 reflecting the current framework, and that is the document to work from. The European stage remains six months of Commission examination followed by a three-month opposition period after publication in the Official Journal.

Court proceedings, compensation and criminal actions, contract drafting and advisory work are handled by our law firm, Devin Law & IP, at devinlaw.com.tr. If your matter belongs there we will say so at the first call rather than after an engagement letter.
On Büyükdere Caddesi — the spine of Istanbul's central business district — Ferko Signature places the office minutes from the TÜRKPATENT liaison offices and the headquarters of the companies we act for.
Build a career where registration work is done properly — with the statute open, the case law read and the calendar under control.
Why Devin Patent
Learn the register from the inside. Learn why every entry on it matters.
Attorneyship is a craft learned by doing it under supervision. We train candidates towards the TÜRKPATENT trademark and patent attorney examinations and give them real files from the start — under review, but real.
Junior colleagues work directly with senior attorneys from their first week — search reports, specification drafting, responses to office actions, opposition files and international portfolio administration. Mentoring is structured, feedback is continuous, and responsibility grows with demonstrated ability rather than seniority alone.
To apply, send your CV and a short note describing your interest in working with our firm to info@devinlaw.com.tr. Applications are reviewed on a rolling basis and every candidate receives a response.
