Japanese Patent & Utility Model FAQs
Issuance (Registration)
1. How long before the patent issues after payment of the registration fee?
Patents are normally registered in the JPO 2-3 weeks from when the registration fee was paid. Then, a patent will be issued. Patents are normally issued 4-5 weeks from when the registration fee was paid.
2. When can a Japanese patent be enforced?
The patentee can enforce a patent against infringers when the patent is registered in the JPO. However, since the JPO does not inform us of the date of the registration in the JPO prior to the issuance, it is difficult to know when a patent will be registered. If you would like to enforce a patent before we receive the patent, it will be necessary for us to perform a daily online check to determine whether or not the patent has been registered.
3. Is it possible to obtain multiple certified copies of the Japanese patents granted to an applicant ?
No. It is not possible to obtain either multiple certificates of patent or a certified copy of the certificate of patent. The JPO issues only one certificate for one patentee.
However, a certified copy of the JPO register is obtainable. The JPO will stamp/seal the back page of a copy of the register for a patent.
