A point of main emphasis of our legal services is the drafting of patent applications in German and English language and the prosecution of the applications before the Patent Offices.


We protect our clients’ interests in opposition, nullity and infringement cases – both from the perspective of invalidating IP rights of competitors and enforcing and safeguarding our clients’ corporate IP rights.


We handle trademark and design applications as well as oppositions before the German Patent and Trademark Office and the European Union Intellectual Property Office.

We further have many years of experience in 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.
