I am a qualified Dutch lawyer with also a technical background, and with over 20 years of experience working as a senior (IP) lawyer for various companies. In this roles, I have drafted and negotiated thousands of IP en technology related contracts, from simple technology transfer agreements to contracts for high value and complex technology and IP related deals.

Since 2010 I have my own legal practice, and since 2013 I have been associated with NLO to assist NLO clients with technology and IP related contract matters.

I can help with all kinds of IP and technology related contracts and deals in various technical areas, such as for example technology assignment, licensing, (joint) development, procurement and provision of technical goods and services. As an experienced and skilful negotiator, I can also support clients with (face-to-face) contract negotiations, to bring maturity and balance to the negotiation table
