Inventor File ------------- Source: USPTO The Inventor file includes the patent number, inventor name, street address (if present on the patent record), city, state, country code, zip code (where available), and inventor sequence number of inventors listed on patents generally issued from January 1, 1975 to December 31, 1999. All named inventor information for each patent, as contained in the Technology Assessment and Forecast (TAF) database, are included. Street address data are blank where patent rights are assigned to an organization at the time of grant, as indicated on the front page of the patent. Since this file includes the patent number in each record (in addition to the inventor name and residence information), inventor name and residence information can be repeated in multiple records if those inventors are listed on more than one patent in the file.
