After the patent is transferred, there is a certificate.

If the patent right is transferred, the procedure is as follows: 1. After negotiation, both parties sign the right transfer agreement, and then submit the filing project change declaration to China National Intellectual Property Administration; China National Intellectual Property Administration will issue a notice of change after passing the examination, pay the patent registration fee, and pay the annual fee and stamp duty for the first year after authorization; China National Intellectual Property Administration will produce a patent certificate and issue it to the new patentee (if there is an agent). The patentee recorded in the certificate is the changed patentee. Therefore, after the patent transfer, there is still a certificate to be changed.
