Howrey will open an office in Düsseldorf, the centre of patent litigation in Germany, in September this year.
The firm has hired Christoph Lenz from Bardehle Pagenberg, and he will jointly head the office with Joachim Feldges, who is the managing partner of Howreys Munich office and co-chair of its IP practice.
Lenz will be joined by one associate.
The office will focus on patent litigation, but will also handle trade mark and unfair competition law.
Howrey said it also aims to add an antitrust team in one of its German offices.
