FR 6.8
Patent category FR 6.8 or VI.8 was for Motors divers.[1]
Classifications of French patents, 1904-1958, as we have it here, actually has FR 5.8 or V.8 as Motors divers, and shows no "VI.8". A vast discrepancy, or inconsistency, between outlined administrative protocol and the actual entry of data on a huge number of patent original documents, is feasible.
This classification is of some rare note in that it appears fairly late within our timeline, well after the overwhelming majority of French aero-applicable patents are given FR 6.4 classification, whether or not they put an actual technical emphasis on such a subsystem as motors. It's of note that Louis Renault features prominently here, given his more well-known and sustained application of motor development to automobiles. In practice, and over the longer term, we find that such a key innovator and industrialist, in the field of motors, will factor in as a subsystem contributor, with his motors being used within the airplanes associated with more aero-specific inventors and firms, whether or not there own patents are treated as “whole” airplane concepts.
