Prüfer & Partner is one of the renowned IP law firms in Germany specializing in intellectual property rights. We take care of the protection of ideas, inventions and product developments worldwide and enforce our clients’ claims in court – regardless of whether it is a matter of enforcing technical inventions or other types of property rights or IP rights.

Prüfer & Partner is an IP boutique offering a full range of intellectual property services. Founded in 1972, Prüfer & Partner underwent a successful generational change between 1998 and 2002, when it was taken over by patent attorneys Dr. Dorothea Hofer, Jürgen Feldmeier and Dr. Andreas Oser. Since then, the office has developed into an internationally oriented firm with expertise in almost all scientific/technical fields. With the addition of attorney Andreas Jacob to the partnership, the firm was also able to significantly expand its existing expertise in patent litigation and attorney services in 2015 and 2016.

Prüfer & Partner is a highly regarded law firm specializing in IP with an established global network. It has a strong and carefully selected community of patent attorneys, lawyers and technical specialists and efficiently supports its clients in all IP protection matters. It defends its clients’ intellectual property rights in court and enforces them.

With the last decade, Prüfer & Partner has continuously expanded its expertise in patent and trademark litigation. Dr. Dorothea Hofer and Jürgen Feldmeier have been advising their client “BROTHER Industries” for several years in a complex patent dispute concerning ink cartridges. Dr. Andreas Oser supports the pharmaceutical industry such as parts of the “Novartis Group” in building up their patent portfolio as well as in litigation. Andreas Jacob is active in both patent and trademark proceedings before the courts in Germany, but also supports his clients in international disputes, especially in China-related cases. Other attorneys at the firm, such as Dr. Christian Einsel, also regularly litigate patent cases on both the active and passive side. Dr. Christian Gärtner also handles many opposition and appeal proceedings before the European Patent Office (EPO) and the German Patent and Trademark Office (DPMA). In addition, Marion Ziliox acts for French and Asian clients, among others, in customs actions at the borders of the European Union. Thus, Prüfer & Partner has a profound expertise in the entire IP area.
