Pre-AIA 35 U.S.C. 102(g) Applies to Claims with Effective Filing Dates Before March 16, 2013
Note:
This rule requires that pre-AIA 35 U.S.C. 102(g) applies to claims in a patent application if they have an effective filing date before March 16, 2013, or are part of a continuation, divisional, or continuation-in-part application containing such a claim.

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).

Claims Must Be Patentable Under Both AIA and Pre-AIA Standards
Note:
Each claim in an application must meet the patentability requirements of both the pre-AIA and AIA standards if it has a filing date before or after March 16, 2013.

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.

Care Required for AIA vs Pre-AIA Claims
Note:
When an application filed on or after March 16, 2013 claims subject matter from a prior application filed before that date, care must be taken to accurately determine whether the application is governed by AIA or pre-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. See also MPEP § 2151.

Pre-AIA 102(g) Applies to Patents from Certain Applications
Note:
This rule states that pre-AIA 35 U.S.C. 102(g) applies to any patent resulting from an application that contains a claim with an effective filing date before March 16, 2013.

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).
