Manner of Disclosure Not Critical for Affidavit Under 37 CFR 1.130(b)
Note:
An affidavit under 37 CFR 1.130(b) does not require the same manner of disclosure as the intervening disclosure to be considered prior art.

The manner of disclosure of subject matter referenced in an affidavit or declaration under 37 CFR 1.130(b)(2) is not critical. Just as the prior art provision of AIA 35 U.S.C. 102(a)(1) encompasses any disclosure that renders a claimed invention “available to the public,” any manner of disclosure may be evidenced in an affidavit or declaration under 37 CFR 1.130(b). That is, when using an affidavit or declaration under 37 CFR 1.130(b) to except an intervening disclosure as prior art based on a prior public disclosure by an inventor or a joint inventor, it is not necessary for the subject matter to have been disclosed in the same manner or using the same words. For example, the inventor or a joint inventor may have publicly disclosed the subject matter in question via a slide presentation at a scientific meeting, while the intervening disclosure of the subject matter may have been made in a journal article. This difference in the manner of disclosure or differences in the words used to describe the subject matter will not preclude the inventor from submitting an affidavit or declaration under 37 CFR 1.130(b) to except subject matter in the intervening disclosure (e.g., a journal article) as prior art.

Claims Must Be Rejected If Previously Disclosed
Note:
Examiner must reject claims if subject matter was publicly disclosed by the inventor before filing date.

On May 18, 2021, an attorney for Acme Corp. files a U.S. patent application claiming subject matter X. An inventor’s oath or declaration under 37 CFR 1.63 signed by Maria is also filed with the application. During the prior art search, the examiner finds a journal article authored by Keiko that published on March 16, 2021 and discloses the same subject matter X. The journal article by Keiko is publicly available before Acme's filing date. Accordingly, the examiner should reject the claims to X as being anticipated by Keiko under 35 U.S.C. 102(a)(1). At the time of the rejection, the examiner has no information about Maria’s prior public disclosure.

Keiko's Disclosure as Prior Art Despite Maria’s
Note:
The examiner can use Keiko’s disclosure of Y as prior art even if Maria disclosed X, provided that X and Y are not the same subject matter.

At the time of the rejection, the examiner has no information about Maria’s prior public disclosure and cannot predict how the applicant will respond. Thus, in order to conclude prosecution in a timely manner and avoid the possibility of an additional non-final action, the examiner should consider whether Acme's claim to X can be rejected as obvious over Keiko’s disclosure of Y. The disclosure of Y by Keiko is still available as prior art because Maria’s disclosure of X is not the same subject matter as Keiko’s disclosure of Y. If the applicant shows that the Keiko’s disclosure of X and the genus that encompasses X and Y is not prior art in response to the rejection, the examiner could maintain the obviousness rejection based on Keiko’s disclosure of Y and make the next Office action final, unless it is not appropriate for other reasons. Stated another way, the second Office action cannot be made final if a new obviousness rejection based on Keiko’s disclosure of Y is made in response to the filing of the 37 CFR 1.130(b) declaration, assuming Acme did not amend the claims.

Inventor's Prior Disclosure Anticipates Later Generalized Public Disclosure
Note:
The inventor’s prior public disclosure of a specific feature (X) is considered to anticipate a later generalized public disclosure by another party, even if the latter includes additional elements.

Note that Maria’s prior public disclosure of X is considered to be the same subject matter as Keiko’s later‐disclosed genus that includes X, in the same sense that a species can be said to anticipate a genus. In other words, the inventor is not penalized just because a third party sees the inventor's disclosure and then re‐publicizes it in a more generalized fashion.

Disclosure by Inventor Not Prior Art
Note:
An inventor's public disclosure of subject matter before a filing date does not make it prior art if the disclosure was made by the inventor or a joint inventor.

AIA 35 U.S.C. 102(b)(1)(B) provides that a grace period disclosure shall not be prior art to a claimed invention under AIA 35 U.S.C. 102(a)(1) if subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor. Similarly, AIA 35 U.S.C. 102(b)(2)(B) provides that a disclosure shall not be prior art to a claimed invention under AIA 35 U.S.C. 102(a)(2) if the subject matter disclosed had, before such subject matter was effectively filed under AIA 35 U.S.C. 102(a)(2), been publicly disclosed by the inventor or a joint inventor. An applicant may show that the subject matter disclosed had been publicly disclosed by the inventor or a joint inventor before the disclosure or effective filing date of the subject matter on which the rejection was based by way of an affidavit or declaration under 37 CFR 1.130(b) (an affidavit or declaration of prior public disclosure). Specifically, the affidavit or declaration must identify the subject matter publicly disclosed and establish the date and content of their earlier public disclosure. If the earlier public disclosure is a printed publication, the affidavit or declaration must be accompanied by a copy of the printed publication in accordance with 37 CFR 1.130(b)(1). If the earlier disclosure is not a printed publication, the affidavit or declaration must describe the earlier disclosure with sufficient detail and particularity to determine that the earlier disclosure is a public disclosure of the subject matter, as required by 37 CFR 1.130(b)(2).

The examiner should withdraw the anticipation rejection under 35 U.S.C. 102(a)(1) because the evidence of record establishes that Maria had made a prior public disclosure of the same subject matter disclosed in Keiko’s journal article. It is important to note that if a prior public disclosure is made by a printed publication, 37 CFR 1.130(b)(1) requires that a copy be included with the declaration. Acme has complied with this requirement by supplying a copy of the conference presentation slides. Furthermore, the application file includes an inventor's oath or declaration under 37 CFR 1.63 signed by Maria. Therefore, the record contains sufficient evidence that Maria is the inventor of X.

Examiner Can Maintain Obviousness Rejection Based on Keiko’s Y
Note:
If the applicant shows that Keiko’s disclosure of X and the genus encompassing X and Y is not prior art, the examiner can maintain an obviousness rejection based on Keiko’s disclosure of Y and make the next Office action final unless it is inappropriate for other reasons.

At the time of the rejection, the examiner has no information about Maria’s prior public disclosure and cannot predict how the applicant will respond. Thus, in order to conclude prosecution in a timely manner and avoid the possibility of an additional non-final action, the examiner should consider whether Acme's claim to X can be rejected as obvious over Keiko’s disclosure of Y. The disclosure of Y by Keiko is still available as prior art because Maria’s disclosure of X is not the same subject matter as Keiko’s disclosure of Y. If the applicant shows that the Keiko’s disclosure of X and the genus that encompasses X and Y is not prior art in response to the rejection, the examiner could maintain the obviousness rejection based on Keiko’s disclosure of Y and make the next Office action final, unless it is not appropriate for other reasons. Stated another way, the second Office action cannot be made final if a new obviousness rejection based on Keiko’s disclosure of Y is made in response to the filing of the 37 CFR 1.130(b) declaration, assuming Acme did not amend the claims.

Second Office Action Cannot Be Final If New Obviousness Rejection Based on Keiko’s Disclosure of Y Is Made

Requirement for Inventor’s Oath/Declaration Signature
Note:
The inventor must sign an oath or declaration under 37 CFR 1.63 with the patent application.

On May 18, 2021, an attorney for Acme Corp. files a U.S. patent application claiming subject matter X. An inventor’s oath or declaration under 37 CFR 1.63 signed by Maria is also filed with the application. During the prior art search, the examiner finds a journal article authored by Keiko that published on March 16, 2021 and discloses the same subject matter X. The journal article by Keiko is publicly available before Acme's filing date. Accordingly, the examiner should reject the claims to X as being anticipated by Keiko under 35 U.S.C. 102(a)(1). At the time of the rejection, the examiner has no information about Maria’s prior public disclosure.

Requirement for Examiner to Lack Knowledge of Inventor’s Disclosure
Note:
The examiner must not be aware of any prior public disclosure made by the inventor, Maria, when rejecting claims based on anticipation.

Prior Disclosure via Virtual Conference
Note:
Acme’s attorney must file a declaration signed by Maria to show X was disclosed at a virtual conference before Keiko's journal article disclosure.

In reply to the Office action, Acme’s attorney files a 37 CFR 1.130(b) declaration signed by Maria averring that she had disclosed X at a virtual conference on June 7, 2020, which is prior to the public availability date of Keiko’s disclosure of X in the journal article. The reply also includes a copy of Maria’s presentation slides at the virtual conference. In addition, the reply calls the examiner's attention to the inventor's oath or declaration signed by Maria that is already of record.

Examiner Must Consider Obviousness Over Keiko’s Disclosure
Note:
The examiner must assess whether Acme's claim to X can be rejected as obvious over Keiko’s disclosure of Y, given the lack of information about Maria’s prior public disclosure and the need to conclude prosecution timely.

At the time of the rejection, the examiner has no information about Maria’s prior public disclosure and cannot predict how the applicant will respond. Thus, in order to conclude prosecution in a timely manner and avoid the possibility of an additional non-final action, the examiner should consider whether Acme's claim to X can be rejected as obvious over Keiko’s disclosure of Y. The disclosure of Y by Keiko is still available as prior art because Maria’s disclosure of X is not the same subject matter as Keiko’s disclosure of Y.
