Mr van Kooij is skilled in the many aspects of providing patent services, such as writing and prosecuting patent applications, defending patent applications before the European Patent Office (opposition and appeal), seeking the nullification of patents of possible competitors before the European Patent Office, the Patent Centre and in court, advising clients on the development or strengthening of their IP position, negotiating licence or transfer agreements, producing second opinions and advising on additional IP protection, such as supplementary protection certificates and plant breeders’ rights.

Mr van Kooij advises and supports many large national and international clients on their IP and innovation policy, but is also involved with start-ups, particularly in the field of biotechnology.

In addition to his patent law expertise, Mr van Kooij has become a specialised, proactive adviser whose main concerns are tailored service, cost control and creativity combined with a long-term vision.

Mr van Kooij approaches a case with a pragmatic attitude that gives priority to clarity and transparency for the client. The starting point in a case has to be that one (the client’s expertise) plus one (Mr van Kooij’s expertise) equals three.

In addition to providing patent services, Mr van Kooij derives great satisfaction from sharing his knowledge. He teaches at the University of Strasbourg (Centre for International Intellectual Property Studies) and is an epi tutor. He is also actively involved in increasing IP awareness.
