MPEP § 2159.03 — Applications Subject to the AIA but Also Containing a Claimed Invention Having an Effective Filing Date Before March 16, 2013

Ninth Edition, Revision 01.2024 · last revised R-01.2024

Even if AIA 35 U.S.C. 102 and 103 apply to a patent application, pre-AIA 35 U.S.C. 102(g) also applies to every claim in the application if it: (1) contains or contained at any time a claimed invention having an effective filing date as defined in 35 U.S.C. 100(i) that occurs before March 16, 2013; or (2) is ever designated as a continuation, divisional, or continuation-in-part of an application that contains or contained at any time such a claim. Pre-AIA 35 U.S.C. 102(g) also applies to any patent resulting from an application to which pre-AIA 35 U.S.C. 102(g) applied. See MPEP § 2138 for guidance on pre-AIA 35 U.S.C. 102(g).

Thus, if an application contains, or contained at any time, any claim having an effective filing date that occurs before March 16, 2013, and also contains, or contained at any time, any claim having an effective filing date that is on or after March 16, 2013, each claim must be patentable under AIA 35 U.S.C. 102 and 103, as well as pre-AIA 35 U.S.C. 102(g), for the applicant to be entitled to a patent. However, an application will not otherwise be concurrently subject to both pre-AIA 35 U.S.C. 102 and 103 and AIA 35 U.S.C. 102 and 103.

For these reasons, when subject matter is claimed in an application filed on or after March 16, 2013 having priority to or the benefit (e.g., under 35 U.S.C. 120, 121, or 365(c)) of a prior application filed before March 16, 2013, care must be taken to accurately determine whether AIA or pre-AIA 35 U.S.C. 102 and 103 applies to the application.
