(ii) where the applicant receives a notice of the grounds for rejection (and where the examiner issues a notice of revocation of decision to grant patent for ex officio reexamination, excluding a notice of grounds for rejection which has been issued before the examiner issues that notice) which has arisen as a result of an amendment following a notice of the grounds for rejection: the applicable time limit is the period for submission of arguments against a notice of the grounds for rejection thereof; or
