ueber_unsis an internationally established patent law firm based in Munich, Germany. We are working for German clients and firms from abroad with about an equal share.

Our main field of activity is the preparation of patent applications and their filing and prosecution at the national and international Offices. It is our daily practice to prepare patent applications in English language which are specifically tailored to the legal requirements in the most important jurisdictions (Europe/Germany, USA, Japan, China).

We have many years of experience in representing and supporting our clients in invalidation actions and infringement proceedings before German courts. Our scope of activities also covers the filing of trade mark and design applications and representing our clients in trade mark and design registration and opposition proceedings.

We advise and represent a spectrum of clients ranging from Start-Ups and mid-size businesses to internationally operating major corporations. We offer to provide our clients with an individual form of cooperation customized to meet their specific needs and wishes. This includes web portal-based communication with company’s IP departments, availability of encrypted correspondence and standardized reporting based on the preferences of the client.

Our priority goal remains to ensure our legal advice is at its highest quality and effectiveness. We therefore demand high standards with regard to professional experience, academic qualification and commitment of each individual in our team.
