Bavaria
Bavaria was an independent kingdom until 1871, when it became part of the German Empire.
Bavaria did have its own patent office, which could be petitioned by foreign applicants. The office granted patents for a variable number of years at a [~ 1l. 10s.] per annum charge. It was a member of the Zollverein custom league which apparently had some kind of mutual understanding about intellectual property.[1]
Augsburg, Bavaria, was the hometown of balloon maker August Riedinger and the headquarters of his company August Riedinger Ballonfabrik Augsburg G.m.b.H..
Alexander Donges, Felix Selgert, Jochen Streb, and coauthors have a database of patents from across the German states before the 1871 unification.[2][3] Using county-level data for Imperial Germany, Donges and coauthors found that the parts of Germany that were occupied longest by France in the 1789-1815 period had TWICE as many patents-per-capita as the counties that were never occupied by France. Inference: the French occupations broke loose some "bad" institutions and installed ones that were more effective for generating modern technological growth.[4]
The submitter of Patent US-1910-970262 (filed in 1908) describes himself as a subject of the King of Bavaria. The phrasing seems bizarre since Prussian Germany had included Bavaria since the 1870s. Is it possible August von Perseval was making a political statement there?
