Archivo Histórico
The Historical Archive is part of the Oficina Española de Patentes y Marcas (OEPM) site, an official government site in Spain which handles patents, trademarks and related issues. The Archive has been maintained and developed as a joint project with the Universidad Autonóma de Madrid since 1999. It includes searchable databases covering the history of privileges (1826-1878), patent applications (1878-1966) and trade marks (1865-1910). For each database, guidance is given regarding background, search strategy and fields available.
