De Louvrié
Charles de Louvrié, possibly "Jean-Charles de Louvrié", was an aero inventor, Paris (5, boulevard Richard-Lenoir, Seine). It is possible that this individual was exceedingly prolific, in terms of innovation beyond aeronautics. (I have cross-referenced specifically aeronautic patents, sharing the same inventor address, and so forth, which is fine. The only original document on hand may, only possibly, pertain to aviation, but I believe these are all patents registered by the same man, again possibly "JEAN-Charles de Louvrie". There are some issues of legibility.)
He is also associated with Paris (17 et 19, rue de Lille, Seine), Clermont-Ferrand (39, rue Montlosier, Puy-de-Dôme). "Delouvrié", that is, Jean Delouvrié, is of note in that he hadn't turned up, and still doesn't, under per se aeronautic searches within INPI, but he registers in 1850 and 1851 with work in steam propulsion, preceding his per se aeronautic work.
Regarding Patent FR-1880-120194, it seems fairly definite that is a mere certificate of addition relative to Patent FR-1877-120194, and that it is in fact redundant relative to Patent FR-1880-120194E. It is the inclusion of patent agent Dufrené which primarily justifies the retention of the page.

Patents whose inventor or applicant is De Louvrié
- Patent FR-1877-120194 (English title: Apparatus of aerial navigation called : "The Anthropornis")
- Patent FR-1863-nd (Filing date: 1863-11-03)
- Patent FR-1863-60712 (English title: System of aerial navigation without balloon, Filing date: 1863-11-01)
- Patent FR-1868-83069 (English title: system of aerial navigation without balloon, Filing date: 1868-11-03)
- Patent FR-1880-120194.1 (English title: Apparatus for aerial navigation, Supplementary to patent: Patent FR-1877-120194)
(I believe a Patent FR-1868-83069 may be particularly in order, very very likely the same "de Louvrie", and specifically aeronautic.)
