Notes

  • The patent number key is rft.number. There is no patent_number key in the registered format.
  • Kind codes are defined by each patent office and catalogued in WIPO Standard ST.16. In the US, B1 means granted without a previously published application, B2 granted after a published application, and A1 a pre-grant application publication.
  • Only rft.inventor is repeatable; rft.assignee may appear once.
