Provision of JP Authority File

7 March 2018
Patent Information Policy Planning Office

An Authority File provides a definitive list of all patent document numbers issued by a patent office. The authority files enable private business providers and patent offices to assess the completeness of their collections of publications of other patent offices. The Japan Patent Office provides the file for the JPO publications (hereinafter “JP authority file”) on the JPO’s website.
The JP authority file until December 2017 can be downloaded in the website below.

As to the Authority files of other IP5 offices, see the URL below.
