Service by Publication

For cases where documents have not been serviced by delivery (undeliverable to the recipient, etc.), the JPO eventually executes Service by Publication by means of publicizing such information in the Official Gazette and the Patent Gazette, posting in the area designated for posting at the JPO office, or displaying on PCs placed at the JPO office for public perusal. (Patent Act Article 191 (where applicable mutatis mutandis to Article 55-2 of the Utility Model Act, Article 68-5 of the Design Act, and Article 77-5 of the Trademark Act.))

The articles regarding “Service by Publication” in the Patent Gazette have been transferred from the Gazette publication site to this site for an easier access to a broader audience (as of July 3, 2023).

※Introduction of Service by Publication Under International Mail Service Suspension
