This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.
The filing date of a Continued Prosecution Application (CPA) is determined differently from other types of patent applications. For a CPA, the filing date is the date on which a request for a CPA is filed on a separate paper.
The MPEP states: The filing date of a continued prosecution application is the date on which a request on a separate paper for an application under this paragraph is filed.
This means that unlike regular applications where the filing date is typically the date all required components are received, a CPA’s filing date is based solely on when the CPA request is submitted, provided it meets the necessary requirements.
