    “Plausibility” in Turkish Patent Law and Its Impact on Invalidation Proceedings

    The concept of plausibility – which has been the subject of numerous evaluations, especially by the European Patent Office (“EPO”) and frequently debated in academic circles in recent years – has not yet found a place within the scope of any legal regulation in Turkey.

    Preliminary Injunction Decisions against Patent Trolls to Prevent the Enforcement of Patent Rights

    Determination of Evidence in Disputes Over Pharmaceutical Patents

    The determination of evidence is a crucial interim legal protection measure in Turkish law that assists in proving the matter in question. In disputes relating to pharmaceutical patents, the determination of evidence is a prerequisite to benefit from a preliminary injunction. Under the Industrial Property Law No. 6769, judicial authorities can order immediate and effective interim measures to protect evidence related to an alleged infringement. However, access to information is limited for drug patent holders, making it difficult to obtain proof to prove preliminary injunction conditions have been met. Therefore, a court-ordered evidence determination decision is necessary for drug patent holders to benefit from the preliminary injunction institution.

    Lack of Regulation on Plausibility Attacks in Turkish Patent Law

    The plausibility concept in patent law is not yet regulated in Turkish legislation, and there is no consensus on the Turkish word that corresponds to this legal term. However, plaintiffs have started to argue the requirement of plausibility in Turkish invalidity proceedings. The issue of plausibility is particularly important with regard to pharmaceutical patents, as all clinical studies' test data may not be obtained by the patent application's date. Therefore, it is still a subject of debate how much research should be included in the patent application and to what extent post-published evidence can be used. The EPO Enlarged Board of Appeal's G 2/21 decision may bring about important standards regarding plausibility, which will affect Turkish patent law.

    The Danger of De Facto Abolishment of the Right to Preliminary Injunction by the Determination of Evidence in Terms of Pharmaceutical Patents

    Temporary legal protection in pharmaceutical patent disputes relies on evidence determination to prove a case. Drug patent holders must get a preliminary injunction to keep infringing products off the market because patent rights are limited. Without a court order, infringing drug information is difficult to obtain. Patent holders must establish evidence under Article 400 of the Code of Civil Procedure and Article 150/3 of the Industrial Property Law to obtain a preliminary injunction. Different court evidence determination methods can affect pharmaceutical patent disputes.
