What's the use of rejected invention patents?

Legal analysis: the rejected invention patent is invalid and useless. Re-examination and rejection is the only remedy for the rejection of patent applications. The Patent Reexamination Board accepts and examines the request for reexamination and makes a decision. Cases requesting re-examination include cases requesting patent re-examination because they refuse to accept the decision to reject the patent application in the preliminary examination and substantive examination procedures. Only the patent applicant has the right to start the patent reexamination procedure, and must submit it to the Patent Reexamination Board of the State Intellectual Property Office within 3 months after receiving the notice of rejection.

Legal basis: People's Republic of China (PRC) Patent Law.
