The DWPI (files WPINDEX, WPIDS and WPIX) on STN has been enhanced with thesauri for the European Patent Classifications

26. April 2011

European Patent Classifications are being added to the DWPI database (files WPINDEX/WPIDS/WPIX) for some time already. Now thesauri are being made available for the /EPC and /ICO search fields to make navigating through the maze of codes easier. For available relationships see HELp RCO.
