JUVE Comment

As a patent attorney firm in prosecution and litigation, this Frankfurt outfit has a strong reputation. In addition to oppositions and nullity suits, the patent attorneys broadened their activity in infringement cases at the side of some renowned litigation firms. Dahmen for example, worked with Arnold Ruess to successfully defend a Sanofi patent against Mylan. Besides its litigation work, the firm captured prosecution clients as result of the merger with another Frankfurt outfit the previous year. K&S also managed to step up its work for Asian companies, for example the Japanese mechanical engineering companies Sanden and Fanuc, as well as clients from Taiwan and China. A patent attorney with Chinese roots often brings in such work for the firm.
