Japan Patent Office Information on Country-based Consolidated Patent Examination to be Accessible

The Japan Patent Office (JPO) will launch a service to provide the public with information on patent examination concerning PCT international applications, as well as applications filed with the five major intellectual property offices (IP5 offices), namely the JPO, the United States Patent and Trademark Office (USPTO), the European Patent Office (EPO), the State Intellectual Property Office of the People’s Republic of China (SIPO) and the Korean Intellectual Property Office (KIPO), which is accessible collectively for the first time in the world. Through this one-stop service, intellectual property (IP) users will be able to access international examination information.

1. Background

As enterprises are advancing business development overseas, they have been filing IP applications concerning the same invention in multiple countries and regions. To address this situation, the JPO has been advancing the cooperation with the rest of the IP5 offices and the World Intellectual Property Organization (WIPO) in developing a system to share information on patent examination (Dossier information) among IP offices.

The JPO will start the provision of a dossier information sharing service to IP users. Through this one-stop service, IP users will be able to access information on patent examination that is useful for preparing their IP strategies from the global viewpoint.

2. Outline of the service

On July 25, 2016, the JPO will launch a new service titled “One Portal Dossier (OPD)” through the Japan Platform for Patent Information (J-PlatPat) website to provide IP users with Dossier information.

The major characteristics of the service are as follows. For details on how to use the screens of the service, see the Appendix (in Japanese). (PDF:316KB)PDFfile
