The addition of a new FI thesaurus to in INPADOCDB and INPAFAMDB enables thesaurus-based searching of Japanese patent classifications. The fully functional thesaurus, attached to the field /FCL, allows viewing of the definitions of the FI-terms, their hierarchical relationships, etc. Use the FI thesaurus to expand search retrieval by including hierarchically broader and narrower terms in your searches. The FI thesaurus is based on the latest revision of the FI classification scheme (4/2024) including 190,000 file index terms and will be updated twice a year in the future.

In addition, the FI thesaurus in Derwent World Patents Index (DWPI) has been updated and enables the use of the newest FI terms in your searching of Japanese patents.

Typically, applications of the FI thesaurus link the EXPAND or SEARCH command with specific relationship codes and the field /FCL.
