As a patent attorney, Martin primarily focuses on the drafting of applications, arguing patentability, and litigation. He is an active AIPPI member, with activities mainly in the field of pharmaceutical products. His direct experience with research and chemistry, in combination with his understanding of patent law, ensures efficient communication with both inventors, specialists and lawyers. Martin’s work is characterized by a thorough insight into the working of an invention, an eye for detail, and swift understanding of technical relevance, as well as by a social attitude. A particular focus of Martin’s work as a patent attorney is on pharmaceutical products, food and nutraceuticals.

In his capacity as European Patent Litigator, Martin is allowed to act as UPC representative.

Directories

• “Recently, pharmaceutical litigation by patent attorneys such as Jetze Beeksma and Martin Klok for research-based industry has dominated more than in previous years. Both partners are stars in the Dutch patent scene” (JUVE Patent 2024).
• Featured as a patent attorney with technical specialty: pharma and biotechnology  (JUVE Patent 2024)
• The Netherlands Practitioner of the Year (Managing IP 2024)
• Recommended individual (JUVE Patent 2021, 2022, 2023, 2024)
• “Martin Klok was […] highly visible. He is active in several cases alongside Freshfields Bruckhaus Deringer for Novartis. But his greatest success was the PI case for Bristol-Myers Squibb against generics manufacturers over blood-clot drug apixaban, together with Hogan Lovells”(JUVE Patent 2023)
• Recognized as ‘Notable Practitioner’ (2020, 2021, 2022, 2023, 2024) by Managing IP
• “Rising star Martin Klok is ‘incredibly dedicated to understanding issues and distilling relevant information’.” (IP Stars Handbook MIP, 2017)
• Highlighted as ‘exceptional attorney’ by IP Stars Handbook MIP, 2016
• Martin Klok is complimented for his ability to “understand the real detail” of an application. “He is one of those guys who really can dig into the details and has a grasp of a huge volume of information, the sort of person you like to have at the table because when you have a question he’s on top of it. It’s clear he knows the file better than the attorneys on the other side do.” (IP Stars Handbook MIP, 2014)
