What information is included in the USPTO’s acknowledgment of a CPA request?

When acknowledging a Continued Prosecution Application (CPA) request, the USPTO includes specific details as outlined in MPEP ¶ 2.35. The acknowledgment typically includes:

• The filing date of the CPA request
• The application number of the prior application on which the CPA is based
• A statement that the CPA request is acceptable
• Confirmation that a CPA has been established

The MPEP provides a template for this acknowledgment: Receipt is acknowledged of the ‘conditional’ request for a Continued Prosecution Application (CPA) filed on [1] under 37 CFR 1.53(d) based on prior Application No. [2].

This information helps applicants confirm that their CPA request has been received and processed correctly.
