Patent CH-1902-23691

(This is essentially the same as Patent GB-1901-3691 and Patent HU-1901-22471 and Patent AT-1903-12702 and Patent ES-1901-27364, with the Spanish filing factoring in early, and with the Hungarian patent seemingly being the earliest filed.)
(The only date visible on this original document is “20 février 1901, 7 h. p.”, which is peculiarly vague, particularly in an inter-linguistic context. That is the date we have as the application date on Patent HU-1901-22471, and that would bring things into fine comportment. It is conceiveable of course that a francophone from Monaco would file initially in Switzerland, but we have the Hungarian date of publication 1901.09.28)
(An A. Ritter, of Bâle(Basel), is mentioned as mandataire. See Ritter for some disambiguation.)
