What happens to the prior application when a CPA is filed?

When a Continued Prosecution Application (CPA) is filed, the prior application is automatically abandoned. According to MPEP 201.06(d):

The filing of a CPA is not a filing of a new application. Rather, a CPA is a continuation of the prior application and maintains the same application number as the prior application, i.e., a “streeting” of the prior application.

This means that:

  • The prior application is considered abandoned as of the filing date of the CPA.
  • The CPA is not assigned a new application number but continues under the number of the prior application.
  • All correspondence for the CPA should refer to the original application number.

It’s important to note that this automatic abandonment of the prior application is a key feature of CPA practice, distinguishing it from other types of continuing applications.
