IP boutique offering Eisenführ Speiser has established itself as a strong practice for contentious proceedings, with its forensic advice benefiting from many years of prosecution experience. The close cooperation between patent attorneys and in-house lawyers is particularly evident in infringement proceedings, which are often conducted parallel to nullity actions and opposition proceedings before European and German offices or courts. The practice's broad technical range includes medical and electrical engineering as well as IT and pharmaceuticals. Lars Birken, whose focus industries span mechanical engineering and medical technology, handles patent portfolio management as well as litigation, while Christoph Fehn focuses on standard-essential patent proceedings.
