JUVE Patent

Wachenhausen & Kollegen – Germany 2020

JUVE Comment

This small Munich patent attorney firm not only has a busy prosecution practice with a broad technical spectrum, but also a well-positioned litigation practice. Name partner Wachenhausen is especially visible. Competitors praise him as “very experienced in the courtroom”. One specialty is engineering patents, frequently on the interface with digital technology and computer sciences. Away from this, the firm is often hired for infringement proceedings in other technologies, e.g. by regular client HTC concerning mobile communications or lighting technology for smartphones. Wachenhausen  underlined its international focus with extensive work for Neovasc Tiara. For the Canadian medical technology provider the firm used its entire repertoire, from entitlement actions and nullity suits to filing and EPO oppositions. The firm has seen personnel growth, although one partner left to open his own firm because of strategic differences. Wachenhausen is filing more and more patents for Chinese companies like ZTE, which could prove a solid basis for future litigation.
