The firm was established in 1992 by Christoph Kayser in Hamm/Westfalia on a so-called greenfield site. The firm was well-known in the region on account of its teaching activity stretching over some 10 years at the Gesamthochschule Paderborn, Soest Department. Following continuous growth and some spectacular trademark proceedings, the firm merged with the Munich-based patent law firm of Steffen Möbus. The good relationship with Möbus still exists today, albeit in a purely cooperative capacity.
Due to his Berlin roots Christoph Kayser moved the location of the firm from Hamm to Berlin in 2002. When Dr. Werner Cobet joined the firm he again re-opened the firm’s location in Hamm. The firm’s name then changed to Kayser & Cobet.
