When referencing a prior application in a continuation-in-part (CIP), specific information must be included. According to MPEP ¶ 2.06, the examiner note states:
In brackets 1 and 2, insert the application number (series code and serial number) and filing date of the prior application, respectively.
This means that when referencing the prior application, you must include:
- The application number (series code and serial number)
- The filing date of the prior application
Providing this information accurately is crucial for establishing the proper relationship between the CIP and the prior application.
