A continuation-in-part (CIP) application differs from a regular continuation application in that it adds new disclosure not present in the prior application. While both types of applications repeat substantial portions of a prior application, only a CIP introduces new subject matter.
The MPEP states: This application repeats a substantial portion of prior Application No.[1], filed[2], and adds disclosure not presented in the prior application.
(MPEP ¶ 2.06) This additional disclosure is what sets a CIP apart from a standard continuation.
