On January 12, 1818 Drais was awarded a Großherzogliches Privileg, similar to our modern patent (Baden had no patent law at that time). In addition, he was appointed Professor of Mechanics by Archduke Carl. This was merely an honorary title and not related to any university or other institution. At the same time, he retired from the civil service and continued to receive his salary as a kind of inventor's pension.
