A continuation-in-part (CIP) application is one that is filed so that the applicant can add new claims to a previous application (the 'parent' application) that has not yet been granted.


Filing Continuation

Filing Continuation

The continuation uses the same specification as the pending parent application, it claims priority from the filing date of the parent application, and it must mention at least one of the inventors named in the parent application.

A CIP application is useful when an examiner only accepts some of the claims included in the parent application and rejects others, or when an applicant has not exhausted all the useful ways of claiming the different embodiments of the invention.

During the CIP application process, the applicant may not add any new information to the specification. If the inventor needs to supplement the disclosure of the preceding parent application, a continuation-in part application must be filed.
