First of all, please check whether the time limit for applying for review has passed. Article 4 1 of the patent law stipulates that you can request a reexamination from the Patent Reexamination Board within three months from the date of receiving the notice of rejection.
Second, we can see if the materials were not submitted during the review, which led to inadmissibility. If necessary, you can call and ask, maybe you will accept it when you are finished.
