 Investors formed a company (the "Dansk Riffel Syndikat"; DRS), in 1898 to commercialise the rifle, and bought the patent rights from Madsen and Rasmussen in exchange for royalties on future production.By this time Madsen had left the project to become Minister of Defence in Denmark.In 1899 Lieutenant Jens Schouboe became the manager for the DRS, and a number of subsequent patents bear his name.
