Our Office

The office basically emerged from the former patent department of a well known German automotive supplier, which had been managed by Mr. ter Smitten and which Mr. Rütten had also been a member of. Consequently, terpatent is especially skilled in typical company IP know-how such as contracts and licence agreements, mergers, innovation databases, competitor surveys etc. 

After having spent 14 years in a prominent patent attorney office in Cologne, Germany, Jasper Eberlein-Van Hoof adds comprehensive and successful experience in national and international enforcement of all kinds of IP rights, and is, in addition to patent conflicts, also an expert in trademarks, design protection and unfair competition conflicts.

The office is situated in Düsseldorf, thus benefiting from excellent national and international transport links. The District Court of Düsseldorf is the most important patent infringement court in Germany and one of the most important in Europe and worldwide. Therefore, terpatent has very good relationships with some of the best IP law firms in Germany and Düsseldorf.
