China National Intellectual Property Administration established a patent register when granting the patent right. When the patent right is granted, the contents recorded in the patent register and the patent certificate are consistent and have the same legal effect; After the patent right is granted, the change of the legal status of the patent is only recorded in the patent register, which leads to the inconsistency between the contents recorded in the patent register and the patent certificate. The legal status recorded in the patent register shall prevail.
