Brevets français 19e siècle is a free French patent database created by the National Industrial Property Institute (INPI) of France which provides access to French patent documents from 1791-1844.[1] According to the Patent Search Blog, the database intends to add material to 1902.[1] The database is only available in French, so users may use a machine translation tool (like Google Translate) to translate the interface into their language of choice.

Contents in the database can be searched by title word, applicant, name, address, or profession. According to a description of the interface from the Patent Search Blog, "in the hit list, if you 'voir la notice' you get a printable summary of content, while if you click on 'voir la dossier' you get a set of manuscript pages."[1]


The database has two search options:

  • Quick Search - Search by name of applicant and agent.
  • Advanced Search - Search by number, title, applicant/agent, address, profession, or date range. Users can view an index by selecting the alphabet icon beside each field.

The list of results includes a table with the following fields displayed for each result: document number, applicant name, title, date, option to view a brief notice for the record (bibliographic data), or an option to view a full scanned version of the document. Users can print the result list, return to edit their search, or create a free account in order to gain the option to save selected records in a personal list.
