Jochen Ehlers

Partner at Eisenführ Speiser

Jochen Ehlers mainly works on patent infringement cases and on the prosecution and defence of intellectual property, where his litigation experience stands him in very good stead. Mr Ehlers also has special experience in writing and defending national, European and international patent applications. He also advises clients on all national and European licensing matters. His technical focus is on the fields of telecommunications engineering, semiconductor technology, computer software, image processing, as well as artificial intelligence.

Mr Ehlers represented the winning plaintiffs in the Orange Book Standard case and also in the recent Sisvel v Haier case before the Federal Court of Justice, which both attracted considerable attention as landmark decisions on the antitrust defence (‘FRAND defence’) for avoiding injunctions in SEP patent infringement proceedings.

Mr Ehlers is the publisher and co-author of the Beck’scher Kommentar on the European Patent Convention. In addition, he chairs the Special Committee Q176 of the International Association for the Protection of Intellectual Property for drafting Implementing Regulations for the revised European Patent Convention 2000 and lectures on the strategic deployment of patents at the German Lawyers’ Academy.

Mr Ehlers is recommended every year by several well-known specialist media as one of Germany’s best lawyers in the field of IP rights.

He studied mathematics and physics at the University of Hamburg.
