What is the filing date of a CPA?

The filing date of a Continued Prosecution Application (CPA) is determined by when the request for the CPA is received by the USPTO. As stated in the MPEP, 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 the CPA’s filing date is not the same as the filing date of the prior application, but rather the date when the USPTO receives the proper CPA request.
