Trademarks are very valuable and important assets of a company and their protection has become increasingly important during recent years. We advise our clients regarding the registrability of new trademarks as well as regarding filing and defense strategies for achieving the best possible protection for their trademarks. The German Patent Attorneys of Lederer & Keller are qualified German and European trademark attorneys.

We file German trademark applications at the German Patent and Trademark Office, trademark applications according to the Madrid agreement and according to the Protocol of the Madrid agreement with WIPO, and EU trademark applications with the EUIPO in Alicante. We also file national trademark applications in all countries that provide trademark protection. These filings are accomplished via a network of experienced colleagues throughout the world. We represent our clients through all stages of the examination of the trademark and in all post registration matters, including, if necessary, in opposition and cancellation proceedings.

We advise our clients how they can best enforce their trademark rights and, if the clients are threatened by the trademark of a third party, how they can best defend themselves. We draft and send warning letters, request declarations to cease and desist and send rebuttals to warning letters of third parties. If a trademark conflict cannot be settled out of court, we are prepared to handle trademark litigation cases at all courts in Germany, in all instances, together with experienced lawyers.

We also represent clients in cancellation proceedings against registered trademarks in the German Patent and Trademark Office, the German Federal Patent Court and – together with experienced lawyers – at the regular courts.
