Luxembourg

LU is an abbreviation in this wiki referring to Luxembourg, known more formally as the Grand Duchy of Luxembourg, with the capital city, Luxembourg, most pertinent to our interests. The official government publication, Mémorial du Grand-Duché de Luxembourg, contained lists of patents granted, as well as laws and other information.

We currently have minimal data on this nation, other than the existence of the Aero Club of Luxembourg, access to the "Projet de la loi relatif aux brevets d'invention (1878-1880)", and the city of Luxembourg's being the site of a few pertinent publications. Patents will be forthcoming.

We are presently in contact with les Archives nationales de Luxembourg, located at Plateau du St-Esprit L-1475, Ville de Luxembourg, Grand Duchy of Luxembourg. We are accessing the data available online and are in the process of obtaining archival assistance.

Basic patent historical context

The modern patent system in Luxembourg was incarnated by a law dated 30 June 1880, and published bilingually in the Mémorial.[1] A publication from circa 1899 lists patents still effective in that year, granted between 1880 and April 1899. The serial numbers of these go up to 3563 and the list contains three or possibly more patents directly related to aeronautics.

(The 1894 and 1899 list contain subject matter indexes, which are the closest thing we know, at present, to a system of Luxembourgish patent classifications. The inference of a "system" from this type of documentation parallels the way we have interpreted the British subject matter indexes—c.f. Subject-Matter Index. However the latter are more comprehensive and easily available. We do not yet have any sort of classification data for years after 1899.)

Patents could be submitted in French or German.

Eyeballing the 1880–1899 lists it seems the large majority of filers in this era were foreigners, with the largest numbers coming from Germany and France, but with representation from England, USA, Italy, Australia, and Sweden.

Based on our initial reading of the 1880 law it seems the threshold for a patent to be granted was minimal—i.e., it only needed to meet the basic requirements and was not necessarily examined by an engineer. We are going to move forward with the working model that dates listed alongside patents in official publications are filing dates, but that the "granting" of these patents happened soon after the filing. Publication occurred in the next month's Mémorial.

Working list of patent number to trace

The Mémorial makes abbreviated references in its list of patents expired due to lack of payment. These have numbers and titles, which we can see might relate to aeronautics, though they lack authors, filing dates, and agents. We should be able to track them down eventually.

  • 27, Multiplicateur de toutes les forces connues pouvant s'utiliser sur terre et sur mer, ainsi que pour la navigation aérienne
  • 2066, Procédé et appareil de traction aérostatique (1898/56)
  • 4332, Navire aerien / Luftschiff
  • 7883, Hohlkörper mit Luftzufur für Feurungen
  • 8417, Luftschiff
