How long does it take to review the rejection of utility model patents?

Within 3 months from the date of receiving the notice, request the Patent Reexamination Board for reexamination. The so-called patent reexamination refers to a kind of relief to the applicant when the patent application is rejected.

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.
