The following table contains the searchable indexes (also known as “field codes”) supported by Patent Public Search’s Advanced Search interface for the U.S. Patents Full-Text Database, the US PGPUB database and the USOCR database. The ALIAS column contains the searchable index abbreviation to use in search statements in the Search pane.
Range searching can be done on indexes that have valued (numeric) data.
