New features are:

  • Key Terms (field KT) to support efficient full-text searching and results evaluation
  • Numeric Property Search
  • Standardized and normalized patent assignee names
  • CPC Combination Sets (special indexing assigned by patent examiners to link major features of an invention)
  • New update date UPTX for updated full-text

Also, bibliographic information has been augmented with related application information, and original patent, application, and priority numbers.

More details are available with HELP KEY, HELP NPS, HELP CPC, and HELP PAN in the database.

The Database Summary Sheet ( for DEFULL has been updated to reflect these changes.
