df-mp is a leading European IP law firm based in Munich. Founded in 2000, the firm delivers expert advice on patent prosecution, portfolio management, trademark law, and SPCs to clients ranging from SMEs to global corporations.

df-mp is particularly renowned for its high-stakes litigation practice across the life sciences (df-mp life), technology, and telecommunications sectors (df-mp tech). Operating internationally and before the UPC, EPO, and German courts, the firm frequently coordinates complex cross-border infringement and nullity proceedings.

df-mp’s attorneys have been involved in various high-profile patent litigation proceedings, many of which have had international implications and required df-mp to carry out a coordinating role. For example, df-mp’s biotech/pharmaceutical patents group (also known as “df-mp life”, led by Ulrich Dörries, Sandra Pohlman and Elisabeth Greiner) has handled a number of newsworthy litigation matters, including large and complex EPO oppositions and patent nullity actions before the German Federal Patent Court and the Federal Supreme Court in the area of product, formulation and use patents concerning blockbuster small molecule drugs and biologics.

df-mp and its attorneys are consistently recognised among Germany’s leading patent firms by IAM Patent 1000 (2011–2026), IP Stars (2014–2026), JUVE (2022–2025), and WTR 1000 for excellence in patent litigation, prosecution, nullity proceedings, and trademark practice.
