Horst Schumacher studied physics at the RWTH University in Aachen. Here, he specialized in solid state, metal and experimental physics. After obtaining his degree, he undertook an R&D project in the coal and steel industry and received his doctorate (Dr. rer. nat.) in physical chemistry in 1976, also in Aachen. Inventions of his own relating to the manufacture of coal products brought him into contact with intellectual property law. This was to determine his subsequent career. He trained as a patent lawyer and has been working in the field of intellectual property protection since 1977.

In 1980, having qualified as a German and European patent attorney, Horst Schumacher joined the patent division of Bergwerksverband GmbH in Essen. He also worked as a freelancer for a Düsseldorf patent law office before setting up his own business in 1983. Since 1985, his patent law office has been headquartered in Essen. In 1990, he and Dr. Peter Palgen merged their patent law businesses to form a partnership based in Düsseldorf and Essen. This merger was followed by the 2003 merger with Herrmann-Trentepohl, Grosse, Bockhorni & Partners to form Grosse, Bockhorni & Schumacher which continues its tradition today as GROSSE • SCHUMACHER • KNAUER • von HIRSCHHAUSEN as it is today.

Due to his extensive involvement in international licensing business, Horst Schumacher maintains close contacts in the Far East and the US. He is a member of various professional organizations both in Germany and abroad, has trained many successful patent attorneys and was a co-founder of the official inventors' information centre in Essen.

Horst Schumacher speaks German, English, French, Dutch.
