How is an applicant notified that their CPA request has been accepted?

According to MPEP ¶ 2.30, the applicant is typically notified that their CPA request has been accepted through the first Office action on the CPA. The MPEP states: “Use this form paragraph in the first Office action of a CPA to advise the applicant that a request for a CPA is acceptable and that a CPA has been established.” This notification is important because, as the MPEP notes, “applicant is not notified of the abandonment of the parent nor is a filing receipt normally sent for a CPA.”
