The Spanish patent office at the time of early aviation was Dirección Especial de Patentes, Marcas e Industria (1887–1992) and the current one is la Oficina Española de Patentes y Marcas.

ES is an abbreviation in this wiki referring to Spain.

Barcelona had a particularly active aeronautic scene, with the Asociación de Locomoción Aérea and Revista de Locomoción Aérea beginning in 1908–9. It was also the home of Hispano-Suiza engine makers and the site of aero promotional events including the Barcelona exhibition and 1910 Mamet flight in Barcelona. The city's proximity to France may relate to its relative prominence; for instance, both French and Spanish advertisements can be found in the Revista de Locomoción Aérea.


OEPM and espacenet are currently our main sources for Spanish patents. There is not always a great deal of information available. Espacenet searches (as opposed to entries) give a "Priority date" as well as a main date listed under "Publication info" in the search. The former is probably the filing date, whereas the latter is probably the date granted or published.

Patents were available in Spain before 1887. Urling, 1845 (p. 272) records that foreigners could apply for patents of 5, 10, or 15 years, but would need to put their invention into use within one year of the patent, or else it would be nullified.

Patricio Sáiz is a key expert on 19th century Spanish patents, and wrote an article on the aeronautical ones: "Aeronáutica e invención en la España del siglo XIX". In this article Sáiz gives an inventory of the 15 patents filed in Spain in the period 1826–1878 which concern dirigible balloons (0.27% of 5134 filed) and notes that in contrast to the subsequent work of Torres, none of these designs was realized. See also Sáiz (2014).[1]

It was a Royal Decree of March 27, 1826, which stipulated the rules for the granting privileges of invention and introducing improvements on the basis of the first Spanish Patent Law, which had been enacted in in 1820. A Royal Certificate of July 30, 1833, incidentally, extended these provions to Cuba, Puerto Rico, and the Philippines.[2]


From 1896 the Spanish military service for aeronautics was the Servicio Militar de Aerostación; the Servicio de Aeronáutica Militar, responsible for airplanes, was created in 1913. Pere Vives Vich was a dominant figure in both. Leonardo Torres Quevedo was a key Spanish inventor who also built an early balloon for the Servicio Militar de Aerostación.
