AIA 35 U.S.C. 102 and 103 Apply to Patents Filed After March 16, 2013
Note:
This rule states that AIA 35 U.S.C. 102 and 103 apply to any patent application containing a claim with an effective filing date on or after March 16, 2013.

AIA 35 U.S.C. 102 and 103 took effect on March 16, 2013. AIA 35 U.S.C. 102 and 103 apply to any patent application that contains or contained at any time a claim to a claimed invention that has an effective filing date that is on or after March 16, 2013. If a patent application (1) contains or contained at any time a claim to a claimed invention having an effective filing date as defined in 35 U.S.C. 100(i) that is on or after March 16, 2013 or (2) claims or ever claimed the benefit of an earlier filing date under 35 U.S.C. 120, 121, or 365 based upon an earlier application that ever contained such a claim, then AIA 35 U.S.C. 102 and 103 apply to the application, (i.e., the application is an AIA application). If there is ever even a single claim to a claimed invention in the application having an effective filing date on or after March 16, 2013, AIA 35 U.S.C. 102 and 103 apply in determining the patentability of every claimed invention in the application. This is the situation even if the remaining claimed inventions all have an effective filing date before March 16, 2013, and even if the claim to a claimed invention having an effective filing date on or after March 16, 2013, is canceled.

AIA 102 and 103 Apply to Post-2013 Applications
Note:
This rule states that AIA 35 U.S.C. 102 and 103 apply to any patent application containing a claim with an effective filing date on or after March 16, 2013.

AIA 35 U.S.C. 102 and 103 took effect on March 16, 2013. AIA 35 U.S.C. 102 and 103 apply to any patent application that contains or contained at any time a claim to a claimed invention that has an effective filing date that is on or after March 16, 2013. If a patent application (1) contains or contained at any time a claim to a claimed invention having an effective filing date as defined in 35 U.S.C. 100(i) that is on or after March 16, 2013 or (2) claims or ever claimed the benefit of an earlier filing date under 35 U.S.C. 120, 121, or 365 based upon an earlier application that ever contained such a claim, then AIA 35 U.S.C. 102 and 103 apply to the application, (i.e., the application is an AIA application). If there is ever even a single claim to a claimed invention in the application having an effective filing date on or after March 16, 2013, AIA 35 U.S.C. 102 and 103 apply in determining the patentability of every claimed invention in the application. This is the situation even if the remaining claimed inventions all have an effective filing date before March 16, 2013, and even if the claim to a claimed invention having an effective filing date on or after March 16, 2013, is canceled.

AIA Requirement for Patent Applications Filed After March 16, 2013
Note:
This rule requires that any patent application filed on or after March 16, 2013, must be subject to AIA 35 U.S.C. 102 and 103.

AIA 35 U.S.C. 102 and 103 took effect on March 16, 2013. AIA 35 U.S.C. 102 and 103 apply to any patent application that contains or contained at any time a claim to a claimed invention that has an effective filing date that is on or after March 16, 2013. If a patent application (1) contains or contained at any time a claim to a claimed invention having an effective filing date as defined in 35 U.S.C. 100(i) that is on or after March 16, 2013 or (2) claims or ever claimed the benefit of an earlier filing date under 35 U.S.C. 120, 121, or 365 based upon an earlier application that ever contained such a claim, then AIA 35 U.S.C. 102 and 103 apply to the application, (i.e., the application is an AIA application). If there is ever even a single claim to a claimed invention in the application having an effective filing date on or after March 16, 2013, AIA 35 U.S.C. 102 and 103 apply in determining the patentability of every claimed invention in the application. This is the situation even if the remaining claimed inventions all have an effective filing date before March 16, 2013, and even if the claim to a claimed invention having an effective filing date on or after March 16, 2013, is canceled.

AIA Requirement for All Claims
Note:
If any claim in an application has an effective filing date on or after March 16, 2013, then AIA 35 U.S.C. 102 and 103 apply to all claims in the application.

AIA 35 U.S.C. 102 and 103 took effect on March 16, 2013. AIA 35 U.S.C. 102 and 103 apply to any patent application that contains or contained at any time a claim to a claimed invention that has an effective filing date that is on or after March 16, 2013. If a patent application (1) contains or contained at any time a claim to a claimed invention having an effective filing date as defined in 35 U.S.C. 100(i) that is on or after March 16, 2013 or (2) claims or ever claimed the benefit of an earlier filing date under 35 U.S.C. 120, 121, or 365 based upon an earlier application that ever contained such a claim, then AIA 35 U.S.C. 102 and 103 apply to the application, (i.e., the application is an AIA application). If there is ever even a single claim to a claimed invention in the application having an effective filing date on or after March 16, 2013, AIA 35 U.S.C. 102 and 103 apply in determining the patentability of every claimed invention in the application. This is the situation even if the remaining claimed inventions all have an effective filing date before March 16, 2013, and even if the claim to a claimed invention having an effective filing date on or after March 16, 2013, is canceled.

Claim to AIA Invention Must Have Support
Note:
An application filed on or after March 16, 2013, becomes an AIA application if it is amended to include a claim with an effective filing date on or after that date, provided the new claim has support under 35 U.S.C. 112(a).

If an application filed on or after March 16, 2013, that did not previously contain any claim to a claimed invention having an effective filing date on or after March 16, 2013, (a pre-AIA application) is amended to contain a claim to a claimed invention having an effective filing date on or after March 16, 2013, the application becomes an AIA application (AIA 35 U.S.C. 102 and 103 apply to the application), provided that the newly added claimed invention has support under 35 U.S.C. 112(a) in the application filed on or after March 16, 2013. The application also becomes subject to AIA 35 U.S.C. 102 and 103 even if the claim to a claimed invention having an effective filing date on or after March 16, 2013, is subsequently canceled. If an amendment after an Office action causes the application to change from being governed by pre-AIA 35 U.S.C. 102 and 103 (from being a pre-AIA application) to being governed by AIA 35 U.S.C. 102 and 103 (to being a AIA application), any new ground of rejection necessitated by the change in applicable law would be considered a new ground of rejection necessitated by an amendment for purposes of determining whether the next Office action may be made final. See MPEP § 706.07(a).

Application Disclosing Only Earlier Invention Is Pre-AIA
Note:
An application filed on or after March 16, 2013, that discloses and claims only subject matter from an earlier application is considered a pre-AIA application.

An application filed on or after March 16, 2013, that, as originally filed, discloses and claims only subject matter also disclosed in an earlier application (filed before March 16, 2013) to which the later filed application is entitled to priority or benefit under 35 U.S.C. 119, 120, 121, 365, or 386, is a pre-AIA application. As 35 U.S.C. 132(a) prohibits the introduction of new matter into the disclosure, an application may not contain a claim to a claimed invention that does not have support under 35 U.S.C. 112(a) in the application (that is directed to new matter). Thus, an application cannot “contain” a claim to a claimed invention that is directed to new matter for purposes of determining whether the application ever contained a claim to a claimed invention having an effective filing date on or after March 16, 2013. Therefore, an amendment (other than a preliminary amendment filed on the same day as such application) seeking to add a claim to a claimed invention that is directed to new matter would not change the later filed application from a pre-AIA application into an AIA application.

Claims Must Have Support in Description
Note:
An application cannot include claims for new matter not supported by the description, especially after March 16, 2013.

An application filed on or after March 16, 2013, that, as originally filed, discloses and claims only subject matter also disclosed in an earlier application (filed before March 16, 2013) to which the later filed application is entitled to priority or benefit under 35 U.S.C. 119, 120, 121, 365, or 386, is a pre-AIA application. As 35 U.S.C. 132(a) prohibits the introduction of new matter into the disclosure, an application may not contain a claim to a claimed invention that does not have support under 35 U.S.C. 112(a) in the application (that is directed to new matter). Thus, an application cannot “contain” a claim to a claimed invention that is directed to new matter for purposes of determining whether the application ever contained a claim to a claimed invention having an effective filing date on or after March 16, 2013. Therefore, an amendment (other than a preliminary amendment filed on the same day as such application) seeking to add a claim to a claimed invention that is directed to new matter would not change the later filed application from a pre-AIA application into an AIA application.

Amendments Containing New Matter Must Be Handled Carefully
Note:
When amendments introduce new matter, a new drawing should not be added if discovered by the examiner. Instead, the new matter must be removed from the written description and claims, with claims directed to it being rejected under 35 U.S.C. 112(a).

Amendments that are believed to contain new matter should be treated as follows: (1) a new drawing should not be entered if the examiner discovers that the drawing contains new matter (MPEP § 608.02, subsection II.); and (2) amendments to the written description or claims involving new matter are ordinarily entered, but the new matter is required to be canceled from the written description and the claims directed to the new matter are rejected under 35 U.S.C. 112(a) (MPEP § 608.04). This process for treating amendments containing new matter is purely an administrative process for handling an amendment seeking to introduce new matter into the disclosure of the invention in violation of 35 U.S.C. 132(a), and for resolving disputes between the applicant and an examiner as to whether a new drawing or amendment to the written description or claims would actually introduce new matter into the disclosure of the invention.

AIA Requirement for Subsequent Claims
Note:
An application becomes subject to AIA 35 U.S.C. 102 and 103 even if a claim with an effective filing date on or after March 16, 2013 is canceled.

If an application filed on or after March 16, 2013, that did not previously contain any claim to a claimed invention having an effective filing date on or after March 16, 2013, (a pre-AIA application) is amended to contain a claim to a claimed invention having an effective filing date on or after March 16, 2013, the application becomes an AIA application (AIA 35 U.S.C. 102 and 103 apply to the application), provided that the newly added claimed invention has support under 35 U.S.C. 112(a) in the application filed on or after March 16, 2013. The application also becomes subject to AIA 35 U.S.C. 102 and 103 even if the claim to a claimed invention having an effective filing date on or after March 16, 2013, is subsequently canceled.

New Ground of Rejection After AIA Transition
Note:
Any new rejection due to change in applicable law from pre-AIA to AIA after amendment is considered a new ground necessitated by the amendment.

If an application filed on or after March 16, 2013, that did not previously contain any claim to a claimed invention having an effective filing date on or after March 16, 2013, (a pre-AIA application) is amended to contain a claim to a claimed invention having an effective filing date on or after March 16, 2013, the application becomes an AIA application (AIA 35 U.S.C. 102 and 103 apply to the application), provided that the newly added claimed invention has support under 35 U.S.C. 112(a) in the application filed on or after March 16, 2013. The application also becomes subject to AIA 35 U.S.C. 102 and 103 even if the claim to a claimed invention having an effective filing date on or after March 16, 2013, is subsequently canceled. If an amendment after an Office action causes the application to change from being governed by pre-AIA 35 U.S.C. 102 and 103 (from being a pre-AIA application) to being governed by AIA 35 U.S.C. 102 and 103 (to being a AIA application), any new ground of rejection necessitated by the change in applicable law would be considered a new ground of rejection necessitated by an amendment for purposes of determining whether the next Office action may be made final.

Requirement for Handling New Matter Amendments
Note:
This rule outlines the administrative process for handling amendments that introduce new matter into an invention's disclosure, resolving disputes between applicants and examiners.

Amendments that are believed to contain new matter should be treated as follows: (1) a new drawing should not be entered if the examiner discovers that the drawing contains new matter (MPEP § 608.02, subsection II.); and (2) amendments to the written description or claims involving new matter are ordinarily entered, but the new matter is required to be canceled from the written description and the claims directed to the new matter are rejected under 35 U.S.C. 112(a) (MPEP § 608.04). This process for treating amendments containing new matter is purely an administrative process for handling an amendment seeking to introduce new matter into the disclosure of the invention in violation of 35 U.S.C. 132(a), and for resolving disputes between the applicant and an examiner as to whether a new drawing or amendment to the written description or claims would actually introduce new matter into the disclosure of the invention.
