The utility model patent has been granted free of charge, and now it is not complete to change the patentee. What if the authorization expires?

Hello, if you don't pay the fee after receiving the patent authorization notice, China National Intellectual Property Administration Patent Office will issue a notice deemed as giving up the patent right. Within two months after receiving the notice that the patent right is deemed to be waived, you can submit the right restoration request and pay the right restoration fee at the same time, and then pay other fees required for the license after receiving the notice of successful right restoration. In the meantime, you can continue to go through the formalities for changing the patentee, usually first, so that you can submit the formalities for changing as soon as possible.
