“Hardworking, focused and committed to quality are the hallmarks of Deriş, one of the best firms for patent matters in Turkey. A testament to its robust work in both prosecution and enforcement, the group effortlessly handles multi-jurisdictional patent assignments with the highest level of technical complexity.” Founder Mehmet Nazım Aydın Deriş is a distinguished litigator, prominent in both local and international spheres for his strategies as well as their results. “Offering a fruitful and friction-free collaboration with clientele, Okan Çan is outstanding yet humble. It is not easy to find someone so skilled and experienced in Turkey for IP disputes. Okan provides legal advice with an international dimension and exceeds clients’ expectations. They are definitely in good hands with him.” Emre Kerim Yardımcı and Muazzez Korutürk are hailed for their “efficient cooperation, responsive and cost-effective service.

Firm Profile

Deriş Patents and Trademarks Agency has been a trusted IP adviser for more than 110 years. The firm is a one-stop shop for IP services, with a large and internationally regarded IP prosecution and litigation team. It has been a pioneer in shaping the IP landscape by obtaining precedential court decisions and participating in the preparation of IP legislation upon the invitation of the relevant legislative bodies. Deris provides a wide spectrum of high-quality services that are essential for securing, maintaining and enforcing IP rights.

The firm’s services and counselling are supported by trademark attorneys and technical experts who are national and European patent attorneys, under a unique service approach that combines longstanding enforcement experience with prosecution-technical expertise. The firm’s goal is to secure enforceable IP rights in the market so that they can become sustainable commercial values.

Deriş has an outstanding track record in handling multi-jurisdictional patent disputes of high technical complexity and with a significant impact on the Turkish market. The firm has represented market-leading companies, as well as simplified employee pension owners, in nationwide patent enforcement and technology licensing programmes with successful outcomes. It considers designs as valuable IP assets and has built considerable expertise in design litigation involving spare parts.

Deriş implements patent enforcement programmes that involve litigation, licensing and border protection programmes. One of these border protection programmes was recognised as one of the best in Turkish practice and was presented within the scope of the EU and Ministry of Customs Project in Turkey in March 2017.

Deriş intends to keep its niche IP focus by expanding into areas that overlap with intellectual property such as IT law, media, advertising, competition and telecommunications, with a view to continuing to act as a reference for all IP and IT-related matters in Turkey.

The firm is also developing its technology and helpware to keep up and improve its operational efficiency.

The team consists of 25 attorneys at law, 26 registered trademark and patent attorneys and six European patent attorneys. With administrative and support staff in the trademark, search, design patent, patent and litigation departments, the firm boasts a headcount of more than 85.

Deriş has a strong patent litigation team whose members are qualified to act before the courts in all types of action, including infringement, invalidity, declarations of non-infringement and unfair competition actions. The litigation team is supported by technical experts (national and European patent attorneys), which makes the firm’s service unique by combining longstanding litigation experience with prosecution and technical expertise. This experience and knowledge enable the litigation and patent teams to provide strategic, technical and commercial advice to enforce patents and designs and to protect and defend clients’ inventions.

Deriş manages a considerable amount of provisional protection and validation work with regard to European patents before the Turkish Patent and Trademark Office with high-quality translations, which are vital for the successful enforcement of patents.

The firm offers its patent service not only in Turkey but at an international level too, with experience of acting before international and regional institutions such as WIPO and the EPO, as well as cooperating with a worldwide network of patent agents.

Deris has been ranked as a Top Tier Law Firm for many years, including in 2023 as Tier 1 in Trademark Prosecution and Trademark Disputes by IP Stars.
