Q.Is it possible to reissue the Certificate of Patent？
If the original Certificate of Patent is lost, it is possible to file a Request for Re-issuance of a Certificate of Patent with the Japanese Patent Office. A new certificate will be identical to the original certificate even if a change of ownership or a name/address change is recorded before requesting the new certificate.
Q.When applying to reissue the Certificate of Patent, is a Power of Attorney required?
No. A Power of Attorney document is not required.
Q.A patent has been transferred to a new owner. Can the new owner be listed as the patentee on a reissued Certificate of Patent? Is there any way for the new owner to be shown as the patentee on the reissued certificate?
No. It is not possible to show the new assignee’s name and address on a reissued Certificate of Patent.
If your client would like to have documentation that shows the name and address of the assignee, it is possible to obtain a certified copy of the JPO Register after completion of recordation of the ownership change. The JPO provides official documentation in the JPO Register. From this document, you can confirm patent annuity payment and registered matters, including the ownership and chain of title after patenting. In order for us to obtain a certified copy of the JPO register, we will need to submit an application to the JPO.
Q.When there are co-applicant(s), does the JPO issue multiple certified copies of the Japanese patents granted to the applicants?
Yes. The JPO issues one certified copy of the Japanese patent for each patentee when there is more than one patentee for the patent.
