JUVE Patent

Zimmermann & Partner – Germany 2021

JUVE Comment

Once again, this well-positioned patent attorney firm in Munich stood out for intensive litigation for Samsung. For what is perhaps the firm’s most important regular client, Joel Nägerl and team fought against a whole host of NPEs (including Fipa) regarding mobile communications patents. But work is by no means limited to this important line of business for the Korean company. The patent attorneys recently battled for the conglomerate against Varta over battery technology.

In line with the wide technical focus of the prosecution practice, which is strong in patent filing, the patent attorneys are also active in EPO oppositions and nullity suits. In terms of litigation, electrical engineering and wind energy play an important role thanks to a solid relationship with GE Wind.
