2133.01    Rejections of Continuation-In-Part (CIP) Applications [R-11.2013]

[Editor Note: This MPEP section is not applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2150 et seq. for examination of applications subject to those provisions. See MPEP § 2152 et seq. for a detailed discussion of AIA 35 U.S.C. 102(a) and (b).]

When applicant files a continuation-in-part whose claims are not supported by the parent application, the effective filing date is the filing date of the child CIP. Any prior art disclosing the invention or an obvious variant thereof having a critical reference date more than 1 year prior to the filing date of the child will bar the issuance of a patent under pre-AIA 35 U.S.C. 102(b).
