The JP authority file provides a list of patent/utility model documents digitally issued since 1993, under the WIPO Standard ST.37. The JP authority file allows all interested parties to assess the completeness of the available patent/utility model documentation from the Japan Patent Office.
This file will be updated every half a year, and next update will be provided around February 2021.
