Advance Search Engine for Spanish Patents (1964-1975)

This search engine for patents granted in Spain between 1964 and 1975 was developed by Francisco Llorens and Patricio Sáiz under the Collaboration Agreement between the Spanish Patent and Trademark Office and the UAM (2018-2020). Using innovative text processing and indexing technologies, you can search over 120,000 patents (more than 2.2 million pages).

You can search specific text only on patent specifications and the system will return each matching patent page with the option of downloading the full PDF. Likewise, you can search specific text on certain patent metadata (year of application, title, applicant, international patent classification, and abstract) and the system will return all the pages of the matching patents. Finally, you can combine searches on metadata and the full text of patent specifications.  

Search results link also to matching patents in ESPACENET, where complementary data may be available.
