Patent ES-1912-52792
Jan Jaakson Espacenet results display priority date 1912-04-15 for this patent. Experience has shown that in the case of Spanish data, purported priority date data is actually the filing date of the Spanish patent.
This is a peculiar patent family. It is essentially one invention, with one addition. Patent GB-1911-12232 is the earliest relevant filing, predating that of Patent FR-1911-431069. Patent FR-1912-431069.16054 is the only instance in which we have the addition connected clearly to the initial invention, though Patent CH-1912-62201 is the equivalent of said French addition and was filed earlier. We have more extensive filing of the addition, incidentally.
This Spanish patent is either a fairly late filing of the initial invention, or it is the earliest filing of the addition. Spanish patent data is consistently and somewhat uniformly sparse on Espacenet.
In any case, this is clearly a member of the patent family treated as issuing from Patent GB-1911-12232.
