Document Type Field (DT)

The DT field code divides your search into patents and applications.  There are two acceptable values for the DT field code:

  • G -->  Grants (granted patents)
  • A -->  Applications

Note that Document Type (DT) field code works on all international patents.  By contrast, the Patent Type (PT) field code works only on US documents.


DT:G -->  Returns only granted patents.  The granted patents are from across all jurisdictions.

DT:A --> Returns only applications.  The applications are from across all jurisdictions.
