There are obvious substantive defects in the application documents that the examiner thinks cannot be overcome by means of correction. After the examiner issued the notice of examination opinions, the applicant failed to put forward convincing opinions and/or evidence within the specified time limit, and did not modify the defects pointed out in the notice. For example, the examiner can make a rejection decision.
If the defects pointed out in the notice are modified, even if the defects still exist, the applicant should have the opportunity to state and/or modify the documents again. For subsequent revisions involving similar defects, if the revised application documents still have defects that have been notified to the applicant, the examiner may make a rejection decision.
If there are defects in the application documents that can be overcome by rectification, and the examiner has issued two rectification notices on the defects, and the defects have not been eliminated by the applicant's statement or rectification within the prescribed time limit, the examiner may make a decision of rejection.
