JUVE Patent

Krieger Mes Graf v. der Groeben – Germany 2018

JUVE Comment

The sheer number of proceedings (no other German firm conducts more litigation at present), extremely good ties in the court city Düsseldorf and the huge appeal of Verhauwen secure KM a top position among the German patent litigation firms. In mobile communications proceedings the firm fights on the side of pure NPEs but also for the industry-oriented MPEG4-Pool and its members. This dispute alone gave rise to many proceedings and vast know-how in SEP and FRAND issues. Away from the MPEG4-Pool, industry clients like Saint-Gobain retain KM less frequently than Hogan Lovells, Bird & Bird and Rospatt, although KM does boast its own industry contacts. Good patent attorney connections and numerous proceedings involving various technologies from the high-end Mittelstand ensure a high utilization rate. In pharmaceuticals litigation the firm is less active than direct competitors, e.g. Rospatt and Wildanger.


Infringement proceedings, especially in Düsseldorf and related to telecoms and software. Litigation for NPEs. Employee invention law.

European strategy

The boutique is taking a wait-and-see approach to the potential UPC launch. It still rules out a merger with European firms and instead relies on non-exclusive cooperations. This may limit its opportunities in cross-border proceedings and before the UPC. The firm will therefore have to rely entirely on the huge appeal of its lawyers.
