About Me

I am a partner in our Intellectual Property Group, co-managing partner of our offices in the Netherlands and co-head of our Dutch Life Sciences Group. I specialise in patents and other IP rights, as well as trade secrets.

I have over 20 years' experience and knowledge of cross-border European patent litigation, predominantly in the life sciences and chemical industries, for clients as diverse as multinational corporations, universities and start-ups. In the pharmaceutical sector, I have litigated many patent cases concerning blockbuster drugs.

My practice also includes advising clients on their strategic preparations for the Unitary Patent Package – the Unitary Patent and Unified Patent Court – and on complex multidisciplinary and IP-related deals and disputes involving cutting edge technologies. In addition to litigating before the Dutch courts, I have also represented clients before the European Court of Justice.

I am a member of several professional organisations, such as the International Association for the Protection of Intellectual Property.
