ECLA Thesaurus in CA/CAplus Improves Patent Searching on STN

26. September 2011

Thesauri for ECLA (European Patent Classifications) and ICO (in computer-only) codes now provide STN users a higher degree of specificity when searching patents in the CA/CAplus family of databases on STN. Monthly updates to both thesauri allow STN users to access information about emerging areas of technology. Additional ECLA and ICO code changes in the CA/CAplus family of databases include matching formatting conventions for cross-database searching.

The thesauri can be used with the EXPAND and SEARCH commands in EPC (including EPC aliases, ECLA and EPCLA) and ICO fields.

The following relationship codes are available:
