Our Firm


Sonderhoff & Einsel (Beijing) Patent Agency Office was established in 2012 and provides legal advice in all matters of intellectual property. Our dedicated patent attorneys derive from a wide range of technical backgrounds and have extensive experience in representing international clients in China. The team is complemented by qualified foreign consultants advising the agency in intellectual property practices outside of China, international client relations and linguistic as well as cultural matters.


The firm consults and represents its clients in the preparation, filing and prosecution of patent, design and trademark applications in China. High quality translations from a multitude of languages into Chinese provide the solid basis for all later steps including prosecution and enforcement. Besides general legal consulting in intellectual property matters, the firm’s repertoire also includes providing legal opinions and search services in all areas of practice. If necessary, the firm’s competence can be complemented by cooperation with specialized experts in China in order to achieve optimal results for every case. As an internationally oriented company, all services are provided in English, German and Japanese.


In close cooperation with its clients, Sonderhoff & Einsel (Beijing) develops and implements overall protection strategies for various jurisdictions across Asia. The firm thereby provides a well-established interface to a network of knowledgeable experts in Asia. The firm in particular has a strategic alliance with Sonderhoff & Einsel Law and Patent Office in Tokyo, a partner in Japan with more than 100 years of experience in legal consulting of international clients. As such, our office can comprehensively and efficiently represent the interests of national and international clients in two of the most influential economical areas in Asia.
