Document Number or Patent Number Field (DN OR PN)

Patent and application numbers can be queried using the PN or DN field codes.  PN (Patent Number) is an alias of the DN (Document Number) field.  Since the words "patent number" don't really apply to an application, AcclaimIP uses both codes to query the same field in order to make it easier for users to remember.


  • PN:8832674
  • DN:8832674 --> Search results are the same as the above query.
  • PN:(6876382)
  • PN:US2010076353
  • PN:(6434543 OR 8323439)
