As European patent attorney, he is of the opinion that not only does advice have to be excellent from a technical and legal point of view, but the economic aspects must not be forgotten either. Clearly, advice ought to be commercially useful to the client too.

Paul is mainly involved in protecting inventions that relate to physics and electrical engineering.He has specific expertise when it comes to information technology and communication technology, software, medical applications, optics, seismic data processing, nanotechnology (including microfluidic devices and semiconductors) and mechanics.

In addition Paul has a great deal of experience in conducting opposition procedures at the European Patent Office in order to defend or nullify a patent.  He is extremely talented in conducting oral proceedings.His vast powers of persuasion have ensured him success in several national and international cases, including preventing rejection of a patent application.

Paul began his career as a patent attorney at Arnold & Siedsma in 1996, where he worked as a European patent attorney until 2007. Between 2007 and 2010 he was a partner at another international patent office, before returning to Arnold & Siedsma as a partner. That year Paul opened a new branch in Eindhoven – traditionally the centre of Dutch manufacturing and now also known as a European high-tech region – in order to be able to serve the growing numbers of clients in the south of the Netherlands in the best possible way.
