    IP Practice

The partnership adopts an agile and cost-conscious approach, pragmatically combining and coordinating tailored solutions in complex matters; this approach involves developing IP awareness and enforcement strategies; conducting investigations on counterfeits and evaluating their results; preparing and organising customs seizure of counterfeit goods; serving cease and desist letters to prevent infringing acts; conducting negotiations for settlement agreements; and instituting civil and criminal court actions. Deriş also has a strong patent litigation and prosecution team made up of litigators and Turkish and European patent attorneys. Deriş also has a strong patent litigation and prosecution team made up of litigators and Turkish and European patent attorneys.

    In addition to its thriving litigation practice, Deriş is also experienced using alternative dispute resolution before or during litigation. In this respect, the team enjoys strong connections with the WIPO Alternative Dispute Resolution Centre and actively participates in arbitration and mediation training. Mr Yardımcı has been appointed as a panellist and arbitrator before WIPO for Uniform Domain Name Dispute Resolution Policy matters. Mr Çan has been appointed as a chartered mediator with another member of the firm before the Ministry of Justice in Turkey.

    Deriş provides the full range of IP protection services such as drafting, preparing, filing and prosecuting the application of industrial property rights in Turkey directly and through its first-rate worldwide collaborators in other countries. As Turkey is a member of international conventions such as the Madrid Protocol, the Hague Agreement, the Patent Cooperation Treaty and the European Patent Convention, Deriş files and prosecutes international trademark, design and patent applications directly under these conventions.

Personalised collaboration with clients is key to the firm’s approach; the team believes in fostering close working relationships that result in long-term partnerships.

This helps avoid unnecessary litigation and ensure a trouble-free and uninterrupted operation.

    An Overall Evaluation After the Appeal Decisions in the UK, EPO and in Australia on DABUS Applications

    It will be recalled that, in the subject applications, the applicant Dr. Thaler has designated AI (DABUS)as inventor and claimed that he derived the “right to the patent by virtue of being its creator and owner”. The applicant asserted that the “inventions had been created autonomously” as DABUS, the so-called, “the creativity machine” “produces new ideas and mimics the human brain’s major cognitive circuit: the thalamocortical loop.”

    Video Games: IP Considerations

    IP lawyers and advisors to video game firms must be creative. This is because: the financial value of the video game industry is high and has been increasing dramatically, especially during the covid-19 pandemic;it is important to address the global reach of the video game industry, but to treat it from a local law perspective;numerous actors are involved in the video game industry; andvideo games are complex works of authorship, comprising diverse IP rights.

    Does Turkey Protect Second Medical Use Patents?

    In our opinion, the General Civil Chamber of the Supreme Court shall acknowledge the will of the Parliament to include the decisions of the Enlarged Board of Appeal. Therefore, EPC 1973 shall be implemented together with reference decisions and second medical use patents should be protected. Since there are no exclusions to the protection of second medical use patents in the IP Code, they should be protected in Turkey as long as they are novel and include inventive step.

    Patent Enforcement at the Borders

    Geographically positioned between Europe and Asia, Turkey is a strategically placed country, with a population of 82 million and a larger youth population than any EU member state. Taking its place on the list of G20 countries, Turkey aims to position itself in the global value chain and strengthen its export platform by focusing on high-tech patents, including electronic machinery and equipment, automotive spare parts, railway and maritime transport, and energy generation and efficiency projects. In addition, as a natural transport hub, Turkey is a transitional trade platform between Europe and Asia, which significantly increases the relevance of appropriate IP rights protection.
