The law firm was founded in 1965 by Dr.-Ing. Klaus Durm. His son Frank Durm practiced for some years in a major international patent law firm in Munich before joining his father's firm to become DURM & DURM.

In 2006 the firm merged with the existing patent law firm of Dr. Hans-Peter Pfeifer to become DURM & PARTNER, a partnership according to the German Partnerschaftsgesetz. In the following year Dr.-Ing. Markus Petirsch became a partner of our firm.

In 2017 Dr. Johannes Schmid joined the firm as new partner. Since November 2017 we are named as Durm Patentanwälte.

Our business relationship with the major part of our clients exists continuously since many years, in some cases even decades.
