Cohausz & Florack – Germany 2021

JUVE Comment

Among the patent attorney firms, this Düsseldorf IP boutique is a market leader for patent litigation. In the technical fields of mobile communications and pharmaceuticals, which are rife with disputes, competitors cannot fail to encounter Cohausz & Florack these days. In high-profile SEP proceedings, the patent attorneys are hired alongside external lawyers by both Sharp and Nokia against Daimler concerning connected cars. The relationship with both clients is strong and stretches back over years. Even though the connected cars lawsuits against Daimler have now largely been settled, work is not slowing down, as the nullity suits by Daimler’s suppliers against SEPs are ongoing. Further actions from the Avanci pool are also expected.

In addition, the MPEG LA licence pool has put its trust in Gottfried Schüll and team for years. They are constantly filing new suits for pool members. Most recently, the success in the MPEG LA proceedings convinced other pool members to join a lawsuit against Hisense.

The team also leads the market when it comes to pharma proceedings. It litigated prominently for Bayer in a case of high economic importance involving its blockbuster Xarelto and CRISPR/Cas patents. Gilead also puts its faith in the team led by Arwed Burrichter and Natalie Kirchhofer, who are both among the most renowned litigators for complex, international life sciences proceedings.

The firm responded to its expanding business with organic growth by two patent attorneys. With its strategy of sustainable growth through in-house training, its position as a market leader is nailed down.


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 have proven its strategy to be sound.
