df-mp Dörries Frank-Molnia & Pohlman – Germany 2021

JUVE Comment

The patent attorneys at this Munich IP boutique are standing their ground at the top of the market for patent litigation. It is not only EPO oppositions and nullity suits that play an important role: the patent attorneys are particularly active in infringement proceedings. Unlike competitor König Szynka, they impress with both a strong presence in pharma and biotech actions and in equally top-class mobile communications cases. Ddf-mp, similarly to competitor Cohausz & Florack, has built up a sizeable team of renowned patent attorneys for litigation. With its healthy age structure and frequent trainee development, the firm also has a strong firm structure.

The patent attorneys often partner with external lawyers. Litigation for new client InterDigital in an anti-suit injunction against Xiaomi drew much attention. Here, mobile communications experts Dominik Ho and David Molnia fought alongside the Düsseldorf-based lawyers from Arnold Ruess. The case broke new legal ground.

Df-mp also litigated with Arnold Ruess for claimant Nokia and for EIP Conversant against Daimler in connected cars suits, which were central proceedings last year. These have now been settled, but the df-mp patent attorneys’ vast experience with SEPs should offer a solid basis for future connected cars proceedings, which are expected. The practice is also well known for its frequent litigation for NPEs, including Unwired Planet, Fipa and IPCom regarding SEPs.

The team around Hans-Ulrich Dörries, Elisabeth Greiner and Sandra Pohlman was equally visible in pharma and biotech proceedings. The latter was one of the strawman opponents who recently destroyed a patent for the key CRISPR/Cas technology of Sigma-Aldrich before the EPO Boards of Appeal. The firm boasts a very strong relationship with Amgen, even though a pan-European case against Sanofi concerning a strong-selling cholesterol-lowering drug was lost. Clients such as Pfizer, Sandoz, Zoetis and Hexal ensure a steady stream of work, especially in oppositions and appeals before the EPO.

A large number of well-known clients also trust in the firm for prosecution work, ensuring a good utilisation rate.


Litigation concerning pharma and mobile telecommunications patents. Technical breadth of prosecution practice

European strategy

Although df-mp is frequently involved in international patent proceedings, it sees no reason to have an office abroad or join forces with lawyers. With its strong focus on litigation, the firm would have fewer conflicts of interest than those placing greater emphasis on prosecution. So far, the firm’s success proves this strategy right.
