Turkish Trademark Law Sees Operational Shifts and Judicial Clarifications Heading Into 2026

In 2025, Türkiye’s intellectual property landscape experienced a period of practical evolution rather than fundamental legislative overhaul. Although no major amendments were enacted, several longstanding debates in trademark law began to reach maturity, and new procedural mechanisms became firmly established.

A central development was the full operationalization of the administrative cancellation mechanism for trademarks. This process, now fully functional in practice, represents a pivotal milestone for Turkish trademark law, providing a streamlined avenue for challenging registered marks outside of the courts.

The year also saw renewed focus on the interplay between intellectual property law and competition law, particularly in the context of three-dimensional (3D) trademarks. These discussions highlighted the complexities that arise when trademark protection intersects with market competition, prompting further consideration of how such marks are assessed and enforced.

Turkish authorities have increasingly looked to European Union practice for guidance, especially regarding the assessment of bad faith in trademark applications. The influence of EU standards, such as those articulated in the CP13 Common Practice, has become more pronounced in Turkish proceedings, reflecting a trend toward greater harmonization with European norms.

For the first time, settlements were reached with the Turkish Patent and Trademark Office (TPTO) in trademark matters. This development introduces a new dimension to administrative dispute resolution, offering parties an alternative to protracted litigation and signaling a shift toward more pragmatic administrative practices.

From a jurisprudential perspective, the Turkish Court of Cassation’s approach to short-word trademarks drew particular attention. The court adopted a holistic method when evaluating the similarity of goods across different sectors, moving beyond a narrow comparison and considering broader market realities. This approach was notably applied in a case involving energy drinks and motor oil, where the court’s analysis extended to the overall context of the goods in question.

Artificial intelligence (AI) continued to be a topic of discussion within the realm of trademark law. The ongoing dialogue reflects the growing importance of AI in shaping legal frameworks and the need to address its implications for trademark protection and enforcement.

Several key updates and analyses published throughout 2025 and into 2026 have documented these trends. Notable topics included the full effectuation of administrative revocation, the intersection of 3D marks with competition law, and the assessment of bad faith in trademark applications under EU law.

A significant case during this period saw GSK succeed in a bad faith trademark dispute in Türkiye, underscoring the courts’ increasing scrutiny of application intent and their alignment with international standards.

These developments collectively indicate a period of consolidation and refinement in Turkish trademark law. With practical mechanisms now firmly in place and judicial approaches becoming more sophisticated, Türkiye’s trademark regime is poised for continued evolution, influenced by both domestic needs and international best practices.
