Pre-AIA Rules Apply to Pre-March 16, 2013 Applications
Note:
This rule states that applications filed before March 16, 2013, are governed by pre-AIA 35 U.S.C. 102 and 103, regardless of subsequent actions or amendments.

The changes to 35 U.S.C. 102 and 103 in the AIA do not apply to any application filed before March 16, 2013. Thus, any application filed before March 16, 2013, is governed by pre-AIA 35 U.S.C. 102 and 103 (i.e., the application is a pre-AIA first to invent application). Note that neither the filing of a request for continued examination, nor entry into the national stage under 35 U.S.C. 371, constitutes the filing of a new application. Accordingly, even if a request for continued examination under 37 CFR 1.114 is filed on or after March 16, 2013, in an application that was filed before March 16, 2013, the application remains subject to pre-AIA 35 U.S.C. 102 and 103. Similarly, a PCT application filed under 35 U.S.C. 363 before March 16, 2013, is subject to pre-AIA 35 U.S.C. 102 and 103, regardless of whether the application enters the national stage under 35 U.S.C. 371 before or after March 16, 2013. Additionally, adding claims after March 16, 2013 in an application filed before March 16, 2013 via an amendment which contains new matter does not make the changes to 35 U.S.C. 102 and 35 U.S.C. 103 in the AIA applicable to the application because 35 U.S.C. 132(a) prohibits the introduction of new matter into the disclosure. If new matter is added via amendment, claims directed to the new matter will be rejected under pre-AIA 35 U.S.C. 112, first paragraph. See MPEP § 608.04.

Continued Examination Request Does Not Change Pre-AIA Status
Note:
Even if a request for continued examination is filed after March 16, 2013, an application filed before that date remains subject to pre-AIA 35 U.S.C. 102 and 103.

The changes to 35 U.S.C. 102 and 103 in the AIA do not apply to any application filed before March 16, 2013. Thus, any application filed before March 16, 2013, is governed by pre-AIA 35 U.S.C. 102 and 103 (i.e., the application is a pre-AIA first to invent application). Note that neither the filing of a request for continued examination, nor entry into the national stage under 35 U.S.C. 371, constitutes the filing of a new application. Accordingly, even if a request for continued examination under 37 CFR 1.114 is filed on or after March 16, 2013, in an application that was filed before March 16, 2013, the application remains subject to pre-AIA 35 U.S.C. 102 and 103. Similarly, a PCT application filed under 35 U.S.C. 363 before March 16, 2013, is subject to pre-AIA 35 U.S.C. 102 and 103, regardless of whether the application enters the national stage under 35 U.S.C. 371 before or after March 16, 2013. Additionally, adding claims after March 16, 2013 in an application filed before March 16, 2013 via an amendment which contains new matter does not make the changes to 35 U.S.C. 102 and 35 U.S.C. 103 in the AIA applicable to the application because 35 U.S.C. 132(a) prohibits the introduction of new matter into the disclosure. If new matter is added via amendment, claims directed to the new matter will be rejected under pre-AIA 35 U.S.C. 112, first paragraph. See MPEP § 608.04.

Note:
This rule states that PCT applications filed under 35 U.S.C. 363 before March 16, 2013, are subject to pre-AIA 35 U.S.C. 102 and 103 standards, regardless of when they enter the national stage.

Continued Examination Not New Application
Note:
