How long does it take to change the applicant after the patent is published? Can I change it in two months?

Under normal circumstances, about 2 months after the authorization is not issued, and about 20 days after the authorization is issued, the procedures for changing the specification can be completed (in this case, the electronic patent change notice is received).

If the certificate is authorized, it means that the patentee on the certificate cannot be changed after the change is qualified. You can go to the agency of the local intellectual property office to handle a copy of the register, and the patentee on it will change.

If no authorization is issued, a certificate can be issued after the change description project is qualified, and the patentee on the certificate can be changed.
