Geographic Information System on Patents and Trademarks. Spain, 1850-1939

This geographic information system (GIS) on patents and trademarks in Spain was developed in 2006 by Francisco Llorens, Patricio Sáiz and Luis Blázquez and constantly improved up to 2020. Using Google Maps, Geonames, and other sources we geolocated patent and trademark applicants from 1850 to 1939.

You can locate them on a map filtering by country of residence, type of applicant, application dates, international patent classification, description of the mark, and Nice classification. Clicking on the icons will give you more information and data of the patents or trademarks registered in each location.

We hope you enjoy it. If you do so, please quote our articles and books.
