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.

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.

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.

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.

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.

Copyright/Insights
Authorship of AI-Generated Content under Turkish Copyright Law
Generative AI has become an ordinary instrument of business. Advertising visuals, corporate copy, software code and product designs are now produced with these tools, while the legal question has lagged behind the speed of production: is the resulting content a work in the legal sense, and if it is, who holds the economic rights? The answer is commercially decisive. Content that does not qualify as a work enjoys no copyright protection, and unprotected content may be used freely by anyone, competitors included. Being unable to protect the key visual of a campaign or the launch copy of a product is a concrete commercial weakness. This article assesses the current position under the Law on Intellectual and Artistic Works No. 5846, the Turkish Copyright Act.
One point should be stated at the outset. Turkish law contains no statutory regime specific to AI output. The assessment must proceed from the general provisions of the Copyright Act, and those provisions were drafted with human creativity in mind. That is both the source of the problem and the key to its solution.
The line between tool and producer determines the legal outcome. The nature and intensity of the human contribution must be assessed case by case.
01
The Concept of a Work and the Originality Threshold
The Copyright Act attaches the concept of a work to two conditions (Article 1/B): the content must bear the individual character of its author, and it must fall within one of the statutory categories. The real threshold is individual character, and its definition and scope have been debated intensely in Turkish doctrine. On the broad reading, any intellectual product resulting from a creative activity suffices. On the narrow reading, only products born of serious effort, original in character and capable of establishing a link between the product and its creator cross the threshold. In our view, making protection that easy to obtain damages the balance of interests. Protecting every product that emerges in an ordinary, perhaps accidental way does not encourage true creativity; it obstructs it. For individual character to be accepted, a reasonable perception of a bond between the intellectual product and its creator must arise, and the product must be the result of distinctive work rather than of chance.
The practice of the Court of Cassation gives this framework concrete shape. The settled formula is this: had the work been created by someone else, it would not have been made in the same way and with the same characteristics; individual character is a feature that would emerge only if that particular author made the work (Court of Cassation, 11th Civil Chamber, E. 2020/8509 K. 2022/3996, 24.05.2022; E. 2021/8676 K. 2022/3718, 11.05.2022). The core test, emphasised in case law drawing on Hirsch's classic formulation, is that not everyone could have produced the same work. Quality, by contrast, is not the measure: the product need not be better than its predecessors, for what is sought is the degree of originality, and the assessment is made separately in each individual case. As to authorship, the Act is plain: the author of a work is the person who creates it (Article 8), and Turkish law ties authorship to natural persons. Comparative practice points the same way. The United States Copyright Office has adopted the practice of refusing registration to productions lacking human creativity, and European Union law requires a work to be its author's own intellectual creation.
02
Individual Character in Practice: Selected Examples
The case law has tested this standard across product types. Maps are an instructive example: every kind of map is listed among the statutory categories, but being listed is not enough to be protected, and whether the specific map bears its maker's individual character must be separately established. In architectural projects the test is even sharper. If five different architects commissioned for the same plot would all draw the same project, there is no work, and only unfair competition protection, where its conditions are met, comes into play. If each architect would draw a different project, individual character and copyright protection exist. Adjusting the door, window and room dimensions of an earlier project does not, by itself, create an independent work.
For slogans, the case law imposes strict conditions: using a common everyday phrase as a slogan creates no individual character, and a close bond of attribution between the slogan and its owner, recognised by the public, is required. Compiling existing information has likewise been held insufficient on its own: in a dispute over lecture slides, technical examination established that the content consisted of pre-existing information, and copyright protection was refused. In musical works the principle of partial individual character applies: a general impression of similarity in the listener's ear is not enough for infringement, and a transfer of the elements carrying individual character is required. The common lesson of these examples is this: protection is earned not by falling within a category but by crossing the individual-character threshold.
03
AI as a Tool versus AI as the Producer
The working distinction is this. AI may be used as a tool, in the way a camera serves the photographer or drafting software serves the architect. In that case the creative choices belong to the human: the human sets the concept, selects among generated drafts, and edits, combines and finalises the output. Applying the Court of Cassation's test here clarifies the result. Where anyone entering the same prompt can obtain a similar output, the requirement that not everyone could have produced the same work is not met, and no bond forms between the product and the person. Content generated with a single prompt and used as it came will therefore struggle to qualify as a work. Intensive human contribution changes the picture: the activity of selecting, editing and combining personalises the product, a contribution of that intensity can cross the originality threshold, and the person who made it is the author of the resulting work.
Two settled principles offer guidance in this field. The first concerns compilations. Assembling existing information does not, by itself, create individual character; but where the compilation rests on careful effort and carries arrangement choices peculiar to its maker, the threshold can be crossed. The processing of AI output follows the same logic: using the ready-made output as it stands attracts no protection, while the human work of selecting, filtering and recomposing it can create a protectable product. The second principle is partial individual character. Protection exists only for the parts that carry individual character; yet even partial individual character suffices to make the product a work as a whole. In hybrid productions this principle is decisive: the parts carrying human contribution are protected, the purely machine-generated parts fall outside, and the contract and record-keeping architecture must make that distinction provable.
A further layer of the debate is the distinction between fully and semi-autonomous systems, and comparative law recognises it. The United Kingdom's Copyright, Designs and Patents Act 1988 defines a computer-generated work as one generated by computer in circumstances such that there is no human author. Turkish legislation contains no such definition. Since under the present law individual character can arise only in a natural person, fully autonomous output appears incapable of attracting copyright protection. In our view, that position deserves reconsideration in the face of advancing technology, and granting protection to fully autonomous productions through an exceptional statutory provision would better suit present conditions. In semi-autonomous production, by contrast, the human influence is high both in writing and in applying the code, and individual character should there arise only in the natural person concerned. This distinction is the statutory-level counterpart of the tool-versus-producer distinction described above.
An example makes the originality debate concrete. Ask a person twice, with the same instruction, to draw a purple baby elephant, and the two drawings will differ: the grip of the pen, the lines and the colouring change each time, and creativity enters at precisely that point. Give the same prompt twice to an AI system and it stays, as a rule, within the variety its algorithm permits. Considering that AI cannot form a declaration of intent and operates within the boundaries its creator drew, the conclusion is that individual character in the classical sense does not arise in the machine. At the same time, the limits of the human brain's own capacity for variation are not fully known either, and categorically denying AI any capacity for originality is, in our view, equally unsound. The debate is open at the level of legal policy and awaits resolution by statute.
Proving which side of the line a given output falls on is a matter of records. Which prompts were given, how many drafts were generated, which selections were made and what changes were carried out by hand should all be documented. Those records will be the principal evidence in any future originality dispute. An undocumented production process remains unprovable, however intensive the contribution actually was.
“In AI output, the insurance policy of ownership is the documentation of the production process. Where there is no record, the contribution counts for nothing.”
04
Practical Consequences for Companies
The first consequence concerns work product. The economic rights in works created by employees in the performance of their duties are, as a rule, exercised by the employer (Article 18 of the Copyright Act). But that presumption operates only where a work exists; unprotectable content produced by an employee with a single prompt never enters it. The second consequence concerns client relationships. Agencies and software developers pass their work to clients by assigning economic rights, and where the AI-generated part of the deliverable is unprotectable, the subject matter of the assignment itself becomes doubtful. Declaring the use of AI in service agreements has become important for precisely this reason.
The third consequence is infringement risk. Generative models are trained on existing content, and it is entirely possible for an output to resemble a third party's work. When resemblance turns into an infringement claim, liability as a rule stays with the party that used the content. The risk must be managed contractually: content procured from suppliers should carry warranties as to third-party rights, and for critical campaigns the originality of the output should be separately checked before publication.
05
Contract and Policy Recommendations
Corporate use should rest on a written policy. The policy should determine which tools may be used for which work, and the entry of confidential information and client data into such tools should be separately regulated. Documentation of production processes should be mandatory. Client agreements should state expressly the scope of the AI contribution and the limits of the rights assignment. For assets whose copyright status remains uncertain, alternative layers of protection should be considered: trademark registration can protect slogans and logos, design registration can protect product appearances, and unfair competition rules offer an additional ground against the copying of work product.
06
A Checklist
Put AI use on a written corporate policy, and restrict the entry of confidential information and personal data into the tools.
Document the production process: record prompts, drafts, selections and the changes made by hand.
Keep the human contribution at the centre of production, and do not take single-prompt output into commercial use as it stands.
Add to client and supplier agreements an AI declaration, the scope of the rights assignment and warranties covering third-party rights.
For assets whose copyright status is uncertain, consider trademark and design registration and the protection of unfair competition law.
The legal regime of AI output is not yet settled: there is no statute, and judicial practice is still forming. In this environment of uncertainty, what protects a company is cautious structuring. Documenting the human contribution, drafting agreements in plain terms and activating alternative layers of protection are the measures available today. The uncertainty will one day be resolved by case law or by statute. The company that meets that day prepared is the one whose records and contracts are already in order.

Reach us about a new filing, an office action, an opposition deadline or a portfolio you would like reviewed. Every enquiry receives a clear assessment of scope, timing and cost before any work begins.
Istanbul Office
Let's talk.
Our offices are in the Ferko Signature building on Büyükdere Caddesi, at the heart of Istanbul's business district. Whether you are filing a single trademark or restructuring an international portfolio, the first conversation is always with the attorney who will actually handle the file.
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.
