Submit the certification documents signed or sealed by all applicants and inventors before the change. Where an inventor requests a change due to omission or mistake, he shall submit a certificate signed or sealed by all applicants or patentees and all inventors before the change. The confirmation of the inventor shall be based on the premise that the invention right cannot be transferred or donated, and the proof that the inventor has made creative contributions to the substantive characteristics of the changed invention-creation shall be submitted.
