Opposition & Nullity Proceedings
Effectively Defending Patents and Trademarks
Patents and trademarks are core assets of any company and are often at the center of legal disputes. Not every alleged infringer is willing to respect the rights of a patent or trademark owner under a licensing agreement – and sometimes for good reasons.
At DTS, our primary focus is always on the economic and strategic interests of our clients.
Our Services
DTS advises and represents clients at every stage of litigation proceedings – from pre-litigation strategy and out-of-court negotiations to litigation support, parallel opposition and nullity proceedings, the enforcement of judgments, and settlement negotiations.
We act before general courts (Regional Courts, Higher Regional Courts, Federal Court of Justice) as well as specialized bodies, including the Federal Patent Court, the Opposition Divisions of the German Patent and Trademark Office, and the Directorates-General 2 and 3 of the European Patent Office.
Our key areas of practice include:
- Patent infringement proceedings before Regional and Higher Regional Courts
- Nullity actions before the Federal Patent Court and the Federal Court of Justice, as well as opposition proceedings, particularly before the European Patent Office
- Trademark infringement proceedings before Regional and Higher Regional Courts
- Design proceedings before Regional and Higher Regional Courts
DTS is particularly active before the patent dispute chambers in Munich, Mannheim, and Düsseldorf.
Additional Services
DTS is also engaged by patent attorneys, who wish to complement their technical advice with our legal and procedural expertise. These collaborations are characterized by a collegial, trust-based exchange on an equal footing.
In addition, we assist clients with strategic case management of ongoing proceedings. On request, we can work behind the scenes, advising independently of the externally acting attorneys, to streamline processes and achieve the best possible outcomes.
