On the Court of Cassation’s “My Sweet Orange Tree” Decision
The legal nature of translations represents an important issue under copyright law. Indeed, a translation is often not simply a technical transfer between languages; particularly in the context of literary works, it constitutes the product of intensive intellectual labor whereby the translator reconstructs the work by drawing on the culture of the target language, its expressive possibilities, and the translator’s own interpretation. In this respect, a translation may in… »
Goal Celebrations and Other Distinctive Elements
Recent reports in the Turkish press claiming that Warner Bros. has filed a lawsuit against Fenerbahçe footballer Kerem Aktürkoğlu for using the nickname “Harry Potter” on the pitch and in social media content, as well as for performing a goal celebration allegedly referring to the fictional universe created by J.K.

Compensation for Unjust Preliminary Injunctions in Pharmaceutical Patents and Critical Parameters
One of the most complex types of disputes encountered in the field of pharmaceutical patents is compensation lawsuits arising from unjust preliminary injunctions. These compensation lawsuits require meticulous assessment from the perspective of both procedural law and substantive law. Especially, because of the controversies over the nature of fault-based liability arising from the ambiguities in the wording of Article 399 of the Code of Civil Procedure (“CCP”), and where… »
Prohibition of Double Patenting: Assessment within the Framework of the Turkish Patent Office Practice
The prohibition of double patenting is a fundamental principle in patent law that aims to prevent obtaining multiple patent protection for the same invention. This prohibition is intended to prevent both the granting of a second patent for the same invention (narrow sense of double patenting) and the effective extension of the protection period through applications that are not substantially different from each other and contain the same invention idea in terms of technical… »
Can the Exercise of Patent Rights Be Limited by Allegations of Unfair Competition?
Undoubtedly, the initiation of patent infringement actions by patent holders for the purpose of protecting their exclusive rights, as well as the notification of third parties outside the proceedings who are suspected of involvement in infringing activities, fall within the scope of the rights conferred by patent law. Nevertheless, particularly in disputes between originator and generic pharmaceutical companies, the boundary between the exercise of patent rights and the… »
Turkish Court of Cassation’s Stance on Short-Word Trademarks: Analysis
According to the Trademark Examination Guideline of the Turkish Patent and Trademark Office, which is aligned with the European Union Intellectual Property Office (EUIPO) guidelines, the comparison of trademarks should be based on the overall impression created by the marks. In this assessment, the length of a trademark can be an important factor. In general, the shorter a sign is, the easier it is for the public to perceive each of its elements. Conversely, in longer signs… »
Artificial Intelligence and Trademark Law
The impact of artificial intelligence (“AI”) technologies on trademark law has been among the frequently debated topics over the past year. As also discussed in our article published last year, while these technologies accelerate processes in terms of trademark registration procedures, they simultaneously necessitate a re-assessment of the human-centered criteria traditionally applied in trademark law. Indeed, Intellectual Property (“IP”) offices worldwide continue to… »

Functional Equivalence Across Jurisdictions: Convergence Between Turkish Patent Law and the Unified Patent Court
Barely two years after its operational launch, the Unified Patent Court (“UPC”) has already begun shaping a transnational doctrine of patent infringement by equivalence. Between late 2024 and mid-2025, four landmark first-instance decisions — Plant-e v Bioo (The Hague LD), Brussels LD CFI 376/2023, Mannheim LD CFI 471/2023, and N.J. Diffusion v Gisela Mayer (Paris LD) — established, refined, and finally harmonised the analytical framework for assessing functional equivalence… »
An Important European Precedent: Legal Consequences of Statements Concerning Competitors and Its Implications for Türkiye
In today’s business world, competition among companies is shaped not only by the quality of their products and services, but also by their communication strategies with the public. However, the legal boundaries of such statements should be carefully determined. Statements made about competitors, particularly in Europe, may constitute “defamation” which are evaluated within the scope of competition law and provisions concerning unfair competition and may lead to serious legal… »
An Assessment of the Unified Patent Court’s International Jurisdiction and the Sovereign Response of Third States in Light of Recent Case Law
The scope of the international jurisdiction of the Unified Patent Court (“UPC”) has, in recent years, become one of the most striking and controversial issues in patent litigation. Having commenced its operations in 2023, the Court was established with the objective of creating a uniform and centralized patent adjudication system across Europe. However, through its recent decisions, the UPC appears not to confine its jurisdiction to Contracting Member States alone, but rather… »
