IFIALL Enhanced with the Addition of Cooperative Patent Classification (CPC) Data

November  25th,   2013

Effective November 24, 2013, Cooperative Patent Classification (CPC) data will become available for the first time in IFIALL on STN®. A number of new search and display fields will be introduced in IFIALL, as well as a CPC thesaurus. All available CPC data will be loaded during 4Q2013. A database banner will provide updated information on CPC data coverage as backfile content is added to IFIALL.

Two fields in IFIALL are being reloaded with enhanced data:

  • ARTU (ArtUnit) – the USPTO art unit which examined the patent
  • XPD (Expiration Date) – calculated patent expiration date
