Definition of Field codes
On the PATENTSCOPE® Search Service, you can access a list of all indexed fields from the 'Field Codes' link at the top of the Advanced Search page. These Field codes are applicable to the Advanced and Simple search interface if you prefix the word you are searching for with the abbreviated field name e.g. IC, followed by a forward slash (/).
The Structured Search interface allows searching in specific fields without the need for typing field codes.
