What is patent registration and what is its function?
When a patent application is granted a patent right, the Patent Office will not only issue a patent certificate to the patentee, but also establish a patent register accordingly. The contents of the patent register include: grant of patent right, patent application right, transfer of patent right, decryption of confidential patent, invalidation of patent right, termination of patent right, restoration of patent right, pledge, preservation and cancellation of patent right, filing of patent license contract, compulsory license for patent implementation and change of name, nationality and address of patentee. 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. When you want to know a patent right, you should not only look at its patent certificate, but also consult the contents of the patent register established by the patent office, which records the legal status of the patent right more comprehensively and accurately.
