1 Replacement due to ownership dispute
After the dispute over the ownership of the patent right is handled by the local intellectual property office (or the corresponding functional department) or judged by the people's court, if the patent right is returned to the claimant, after the decision or judgment becomes legally effective, the parties concerned may request the Patent Office to change the patent certificate while going through the formalities for changing the patentee. Anyone who requests to change the patent certificate shall return the original patent certificate and pay the handling fee. After receiving the request for replacing the patent certificate, the Patent Office shall verify the patent application documents, and if it meets the requirements, it may re-create the patent certificate and send it to the parties concerned. The original certificate shall record the word "replacement" and then be deposited in the patent application documents.
2 certificate printing error caused by the replacement
When there is a typographical error in the patent certificate, the patentee may return the certificate and request the Patent Office to correct it. If it is verified by the Patent Office as a typo, it shall be corrected and a replacement certificate shall be issued to the patentee. The original certificate is marked with the word "changed" and then kept in the patent application documents.
The patent certificate shall not be replaced if the description items are changed due to the transfer, inheritance or gift of the patent right. If the patent certificate is lost, it will not be reissued unless it is caused by the responsibility of the Patent Office.
