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.

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.

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.

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.

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.

Data Protection/Insights
Establishing an Internal Personal Data Protection Board Within the Company
Under Personal Data Protection Law No. 6698, companies holding the status of data controller are obliged to conduct their personal data processing activities in compliance with the applicable legislation and to manage the related processes within a transparent and traceable framework. This obligation is not limited solely to the preparation of written policies and procedures; it also encompasses the ability to demonstrate how personal data is actually processed, monitored and managed within the company in practice.
The fact that personal data processing activities within companies are carried out by different departments — such as human resources, legal, finance, information technologies and operations — may cause the process to become fragmented and difficult to control. This may hinder the continuity of legal compliance and may also complicate the holistic management of the process in the event of a potential data breach. In this context, addressing personal data protection processes within a centralised and systematic structure, under the knowledge and supervision of company management, stands out as an effective approach in practice.
Accordingly, the establishment of a Personal Data Protection Board within the company provides a structure that enables personal data processing activities to be reviewed on a regular basis, decisions taken to be recorded in writing and, where necessary, reported to company management. Beyond supporting the sustainable management of regulatory compliance, such a board structure also contributes to the early identification of legal and operational risks.
The Board convening at regular intervals — such as on a quarterly basis — and the recording of the decisions taken during its meetings in written minutes, preserved in a manner allowing submission when required, constitute important elements demonstrating corporate accountability, particularly in audits that may be conducted before the Personal Data Protection Authority. The documented and systematic conduct of board activities also creates a defensible position that may be taken into account in favour of companies in the determination of administrative monetary fines.
With respect to group companies, since each company holds the status of a separate data controller, adopting a separate Board structure for each company represents a sounder approach. Nevertheless, for reasons of operational efficiency, holding board meetings in a single session while preparing separate board decision minutes for each company is considered a practical and functional method in practice.
A board that meets, decides and records is what turns a policy document into demonstrable compliance.
01
General Assessment and Purpose
Under the Personal Data Protection Law, companies holding the status of data controller are required to conduct their personal data processing activities in compliance with the applicable legislation and to manage those activities within an organisational structure capable of demonstrating compliance at all times. In this respect, pursuant to Article 12 of the Law, which specifically regulates obligations concerning data security, companies are responsible for taking the necessary technical and administrative measures to ensure an adequate level of security and for ensuring the effective implementation of those measures.
The execution of personal data processing activities by different departments within companies may hinder the centralised monitoring and management of those processes. For this reason, addressing personal data protection processes on a regular basis under the knowledge and supervision of company management constitutes a functional approach in terms of ensuring legal compliance and preventing potential risks. The guidelines and principle decisions published by the Personal Data Protection Authority are among the primary sources guiding practice with respect to how data controllers should fulfil their obligations under the Law. In particular, the Personal Data Security Guide (Technical and Administrative Measures) explicitly emphasises that merely drafting data security policies is not sufficient; rather, such policies must be integrated into internal company operations, regularly monitored and kept up to date. This approach necessitates the management of personal data protection processes under a specific organisational structure in a manner that ensures continuity.
Within this framework, a Personal Data Protection Board structure, which enables the systematic monitoring of personal data processing activities, the recording of decisions taken and the submission of those decisions to company management where necessary, stands out as an organisational model commonly preferred in practice.
02
Scope and Internal Function of the Board
Establishing the Board as a structure in which units that intensively process personal data are represented enables data processing activities to be addressed not solely on the basis of written regulations, but also by taking actual business processes into account. Including departments specific to the company’s field of activity — primarily human resources, legal, finance, information technologies and operations — contributes to the management of personal data protection processes in alignment with the company’s actual operational practices.
Within this framework, the Board functions as a coordination mechanism that regularly reviews data processing activities carried out within the company, monitors changes occurring in those processes, and allows for the early identification of potential legal and operational risks. Through this structure, the protection of personal data ceases to be a fragmented area managed solely by specific departments and instead becomes a process that is monitored and managed across the company as a whole.
03
Meetings, Minutes and the Record-Keeping System
The effective functioning of the Board depends on its convening at regular intervals and on the written recording of the decisions taken. Meetings at predefined periods — such as on a quarterly basis — provide a functional approach for reviewing the current status of personal data processing activities and assessing newly emerging risks.
The recording of decisions adopted during meetings in written minutes, and the preservation of those minutes in a manner that allows them to be submitted to company management when required, supports the traceability and auditability of the process. In this respect, the preparation of an informational memorandum setting out the duties and working principles of the Board, together with the drafting of sample board decision minutes, contributes to the concretisation and proper documentation of the Board’s activities.
Quarterly minutes are what an audit actually examines.
04
Accountability and the Burden of Proof in Audits
Pursuant to the principle of accountability, which constitutes one of the fundamental principles of the Personal Data Protection Law, it is essential for companies holding the status of data controller to operate within a structure capable of demonstrating that they have duly fulfilled their obligations regarding the protection of personal data. In audits conducted by the Personal Data Protection Authority, the assessment is not limited to the mere existence of written policies and procedures; rather, how those arrangements are implemented in practice within the company, and through which mechanisms they are monitored, is also taken into consideration.
The existence of a regularly functioning Board within companies, together with the maintenance of records relating to its activities, constitutes a significant basis evidencing that compliance efforts are carried out in practice. This approach provides a framework demonstrating that the company manages the process in a systematic manner in the event of a potential audit or an investigation concerning a personal data breach.
05
Administrative Measures, Organisational Risks and Incident Management
In the guidelines and guidance documents published by the Personal Data Protection Authority — most notably the Personal Data Security Guide (Technical and Administrative Measures) — it is explicitly stated that merely identifying administrative and technical measures relating to data security is not sufficient. Rather, such measures must be integrated into companies’ operational processes, regularly monitored and kept up to date. The approach adopted in the guidelines is based on the principle that personal data processing activities should be managed not on an ad hoc basis, but within a structure ensuring continuity.
Through the establishment of a Board structure, changes occurring in business processes can be reviewed on a regular basis, and in the event of a potential personal data breach the steps to be followed can be managed within a predefined framework. This contributes both to the reduction of operational uncertainties and to the balanced distribution of responsibilities and workload among employees.
06
The Criminal Law Aspect
Acts such as the unlawful recording, acquisition, disclosure or transfer of personal data may, depending on the circumstances, fall within the scope of criminal offences regulated under Turkish criminal law. For this reason, processes relating to the protection of personal data should be addressed not only from the perspective of administrative sanctions, but also, in certain cases, with regard to their criminal law implications.
In practice, it is observed that during investigations concerning personal data breaches, consideration is given to whether companies have adopted the necessary organisational and administrative measures and whether personal data processing processes are monitored in a systematic manner. In this context, the Board structure provides a framework that contributes to the handling of duties and responsibilities relating to the protection of personal data within an institutional structure and to the more orderly conduct of audit and review processes.
07
Structuring the Board for Group Companies
The structuring of the Board stands out as a tool that supports the sustainability of compliance efforts carried out within companies and strengthens internal coordination. Even where an organic relationship and operational integration exist among group companies, it should not be overlooked that each group company has a separate legal personality and, accordingly, holds the status of an independent data controller before the law. Due to this distinction in legal status, the preparation of board decisions, risk assessments and meeting minutes relating to compliance processes separately for each company constitutes the most sound approach in terms of the proper operation of procedures and the discharge of the burden of proof.
08
Board or Committee? Assessing the Structuring Model
There is no explicit provision in the legislation mandating the establishment of a structure under a specific title within companies. Nevertheless, the guidelines and guidance documents published by the Personal Data Protection Authority clearly set out the expectation that data controllers establish the necessary organisational structure to ensure data security.
Within this framework, while it is possible to establish such a structure in the form of a committee or working group, a structure organised at the level of a Personal Data Protection Board, authorised through an internal company directive, offers a framework that is more directly integrated into decision-making processes. With regard to the minimum number of members and the structuring model, practice indicates that a structure composed of at least two or three members, representing units that play an active role in personal data processing processes, is functional. Taking into account academic opinion and the practices of the Authority, a board structure consisting of a limited number of members with clearly defined authority and responsibilities provides an appropriate framework in terms of the effectiveness of decision-making processes, ensuring coordination and sustaining the activities of the Board.
09
Conclusion and General Assessment
The process of personal data protection does not constitute a compliance area independent of companies’ activities; rather, it is an integral part of their operations. The regular, traceable and sustainable management of that process is only possible through a systematic organisational structure. The Personal Data Protection Board structure provides a mechanism that responds to this need and enables companies to address their personal data protection processes within a defined framework.
In this respect, the implementation of a Personal Data Protection Board structure is considered a practice that supports companies’ legal security, ensures preparedness for audit processes and contributes to the more effective monitoring of risks at management level. This approach also offers a framework aligned with the implementation principles set forth in the guidelines and guidance documents of the Personal Data Protection Authority.
