"We must provide reliable support and advice to our clients and not just say what we think they want to hear."

Robbert-Jan de Lang studied chemistry in Utrecht, and wrote his PhD thesis on a subject relating to organic synthesis. Before becoming a Patent Attorney with EP&C in 2004, he worked as a patent attorney at KeyGene NV, a biotechnology company. Robbert-Jan is an all-round experienced patent attorney in the Chemical field, but his focus lays in the food & nutrition. He also has ample experience as an independent expert in patent disputes and conservatory seizures of evidence.

Robbert-Jan is member of the Council 2020-2023 at the EPI (Institute of Professional Representatives before the European Patent Office. His obtained experience as member of the board of the Dutch Institute of Patent Attorneys  from 2005-2018, and President of Dutch Institute of Patent Attorneys from 2014-2018 will be put to good use. In his capacity as president, he still has a seat on the Committee van Acht (Patents). From this position, he is an advisor to the government on developments in the field of patent law. Robbert-Jan also regularly gives lectures and classes on a variety of IP-related topics.

He is a team player, persuasive, to the point and interested in a broad range of subjects. “Intellectual property is only one part of a business’s strategy which is something we always have to bear in mind. This is the reason why we like to work closely with our clients. If a client asks for a patent that is going to be of little use, it is my job as patent attorney to bring this to their attention and look for an alternative. We should be providing reliable support and advice and not just saying what we think they want to hear.”
