Your Business First




"A patent attorney needs to be sharp-witted with a legal and technical background."


Walter Hart studied Civil Engineering at the Technical University of Delft, The Netherlands and joined EP&C in 2002 as a patent attorney. In addition to his specialism as civil engineer, Walter has considerable experience in production machinery, composite products, wind energy, hydrogen, transport and storage systems, drilling technologies, tools and horticultural technologies, general consumer products as well as products for the construction industry.

Before joining EP&C, Walter worked for a civil engineering firm (Fugro Engineers) and as a consultant for an ICT company (CMG). He graduated cum laude in 2005 for his Dutch Patent Attorney exams and has organised various workshops on patent law for EP&C’s clients.

Walter is analytical, enterprising, inventive and motivated. “Obtaining a patent is, in itself, not a very difficult task. However, obtaining a patent that is useful and effective for the business of the client is a whole different matter. This requires that a patent attorney is sharp-witted, and has both legal expertise and a thorough technical understanding. I was brought up surrounded by inventions and can sympathise with my clients like no other. I understand how excited and nervous they feel when they come to us with a new idea. The clients are generally very talented and ambitious people and working with them is very satisfying indeed.”

Walter is actively involved in the unitary patent and the Unified Patent Court, the UPC. He has completed the CEIPI course on Patent Litigation in Europe at the University of Strasbourg. This course provides Walter a right of representation before the UPC. He also wrote a white paper for EP&C on the subject titled: “The unitary patent and the UPC, a revolution in European patent law”.

Walter has a special interest in packaging and writes a regular column on packaging and IP for a leading trade publication. In his spare time, Walter is developing a new, high speed sailboat.


JUVE Patent is a online platform with daily reporting on the European patent market. Walter is recommended as an expert in mechanical engineering.
