Bardehle Pagenberg

Intellectual Property/Patents

Spanish and European Patent Attorney, UPC Representative, Partner

»As a patent attorney, I am lucky: I get to see the latest developments of different technologies. I study each case from every possible angle, looking at technical, legal, strategic, and economic aspects. This is so interesting that I simply cannot put a case down before reaching the best possible solution for my clients.«

Mathieu de Rooij’s practice is focused on oppositions and appeals before the European Patent Office as well as patent drafting and patent prosecution. He is particularly active in the fields of renewable energy, medical devices, metal forming and automotive technology, but his practice includes a wide range of technologies involving mechanical engineering, aerodynamics, electronics and electrical engineering.

He joined Bardehle as a partner to head the Barcelona office of BARDEHLE PAGENBERG after a career as an EPO Examiner and almost a decade as a partner in private practice in Spain. During his years at the EPO, he gained privileged insights into the EPO, its procedures and particularly the minds of examiners.

Mathieu de Rooij also assists clients in infringement cases and disputes spanning multiple jurisdictions, and regularly acts as a technical expert on the validity and/or infringement of patents in Spanish court proceedings.
He has also been active as speaker explaining EPO practice regarding a variety of topics, in collaboration with the EPO and its Boards of Appeal, and frequently lectures on European patent practice in Spain.

Mathieu de Rooij received the Client Choice Award for Patent Law in Spain in 2015 and 2019 as well as the Client Choice Award for Patent Law in Europe in 2017. He has been highly recommended in IAM Patent 1000 for many years.
