JUVE Patent

Lederer & Keller – Germany 2020

JUVE Comment

This Munich patent attorney firm is renowned in the market for its many years of in-depth experience in pharma, biotech and chemicals patents. The purely patent attorney firm’s reputation is based on strong visibility compared to competitors in oppositions at the EPO as well as litigation in infringement proceedings and nullity suits before German courts for manufacturers of generics and biosimilars. Michael Best’s team works alongside lawyers, primarily from large firms, for pharma companies like Hexal and Ratiopharm. Consequently, the team was recently boosted by Marco Fachini, a European patent attorney from Hexal who is highly experienced in EPO oppositions. The team boasts a strong setup overall among chemicals companies, for instance litigating for Solvay in several suits involving catalysts. Companies from Germany, the USA and Japan also hire the firm frequently for filing and oppositions.
