JUVE Patent

Cohausz & Florack – Germany 2020

JUVE Comment

This Düsseldorf IP boutique has long been a leader in the patent attorney market for litigation and prosecution. Clients praise its outstanding quality and responsiveness. It is therefore not unusual for clients to entrust their crown jewel patents to the firm. C&F is especially well positioned for litigation in pharma and mobile communications patents. There are few competitors with equally strong setups in both market segments. In the landmark proceedings concerning connected cars patents, it is currently litigating for Nokia and Sharp against Daimler. In the pharma sector, it conducts central proceedings involving the important CRISPR/Cas technology for regular client Bayer. The firm also operates a technically broad prosecution practice with a strong profile for oppositions and strategic background advice. The personnel structures are solid, with more emphasis than at other patent attorney firms being placed on training its next generation itself.


Litigation related to software, electronics, mobile communications and pharmaceuticals.

European strategy

The nationally positioned IP boutique boasts excellent direct relationships with clients in Germany and abroad. Cohausz & Florack is clearly not following the trend of integrating mixed litigation teams under one roof. In patent infringement disputes it always partners with external lawyers. So far, the firm’s success and visibility in many high-profile proceedings has proven its strategy to be sound.
