We love trademarks
We protect your most valuable Asset
Managing complex brand portfolios has been one of our core competencies for over 16 years. ZIERHUT IP. is one of the law firms with the highest number of national and European trademark applications. We manage numerous international portfolios and maintain a comprehensive network of global agents.
We have many years of experience in registering trademarks, including research and monitoring. For example, we represent in opposition and nullity proceedings against bad faith applicants before the Trademark Offices and the Boards of Appeal of the European Intellectual Property Office.
We have a sophisticated system for monitoring trademarks and we can prevent conflicting trademark become registered by regularly tracking trademark applications published for opposition. We have the know-how to take the necessary steps to fully protect the brands of our clients.
Caring for brands often involves the need for legal enforcement of trademark rights. Due to our international orientation, one of our core competencies is the coordination of cross-border brand disputes. We have extensive litigation experience before German courts but also internationally, for example in the USA and China.
