With my computer science, internet and legal knowledge I specialize in complex legal issues around IT and internet applications.Before taking up my current position, I worked at Philips for nine years as patent attorney and IP counsel. I was responsible for IP contracts and licensing related to software, in particular open source software. I have written and deployed Philips-wide policies on open source usage and release of Philips software as open source. I served as the secretary of Philips’ Open Source Advisory Board.I've published a large number of articles on the subject of law and technology on my website http://www.iusmentis.com/I regularly give lectures on IP law and open source inside and outside Philips. In 2004 I was a part-time IP law teacher at the Renmin and Tsinghua universities in Beijing, China.I'm a member of the Dutch patent bar and the European patent bar. Also I'm a member of the Intellectual Property Owners Association’s Open Source Committee.
