Procedures for Use of DAS at the JPO as the Office of Second Filing

When a patent application or a utility model application claiming priority is filed with the JPO, it is possible to omit the submission of paper priority documents to the JPO by requesting it to obtain electronic data on priority documents from an overseas IP office through WIPO Digital Access Service (hereinafter referred to as the “DAS”).

Please note that, on January 1, 2020, the JPO starts Electronic Priority Document Exchange of an Industrial Design application through the DAS.

1. Acquisition of Access Code for Use of DAS
2. Procedures Taken at the JPO

1. Acquisition of Access Code for Use of DAS

In order that the Office of Second Filing obtains a priority document(s) from the Office of First Filing through the DAS, you need to take the procedures for acquiring an “access code.”

Since an access code is issued by the Office of First Filing, please inquire of the Office of First Filing for specific procedures.

When the Office of First Filing is the USPTO, for the procedures for acquiring an access code and granting the office authority to exchange the priority document data electronically with other IP Offices, please see “Electronic Exchange of Priority Document Data with the United States Patent and Trademark Office (USPTO)”
