Profile

Marcel is experienced in many aspects of patent practice, including drafting and prosecuting patent applications, defending applications before the European Patent Office (opposition and appeal), invalidating patents of potential competitors before the European Patent Office, the Dutch Patent Office and the courts, advising clients on developing and strengthening their IP position, conducting negotiations concerning licences or transfers, providing second opinions, and obtaining additional IP protection such as SPCs and plant breeders’ rights.

Marcel advises and supports many large national and international clients in their IP and innovation strategies, and he is also actively involved with start-ups, particularly in the field of biotechnology.

In addition to his expertise as a patent attorney, Marcel has developed into a proactive advisor in whom tailor-made solutions, cost awareness and creativity with a long-term vision are central. He approaches each case with a pragmatic mindset, prioritising clarity and accessibility for the client. His philosophy is that combining the client’s technical expertise with his legal and strategic experience results in a strengthened outcome: 1 + 1 = 3.

Alongside his patent practice, Marcel greatly values sharing his knowledge. He teaches at the University of Strasbourg (CEIPI) and is an EPI tutor. Marcel is also actively engaged in increasing IP awareness and knowledge at both the operational and management levels of his clients.

Marcel is jointly responsible for the A&S Australia Desk.

Marcel is door IAM Patent erkend als “Recommended Individual in Prosecution”.
