Specification Must Describe Grace Period Inventor-Disclosure Consistently With Declaration Requirements
Note:
The specification must include a statement regarding any grace period inventor-originated public disclosures that is equivalent to the information required in a declaration under 37 CFR 1.130(a).

Applicants can include a statement regarding any grace period inventor-originated public disclosures in the specification upon filing. See 37 CFR 1.77(b)(6) and MPEP § 608.01(a). In order to be effective to show that a grace period inventor-originated public disclosure is not prior art under AIA 35 U.S.C. 102(a)(1) because the AIA 35 U.S.C. 102(b)(1)(A) exception applies, the statement must convey the same information as would be required in a declaration under 37 CFR 1.130(a). See MPEP §§ 717.01(a)(1), 2155.01, and 2155.03. An applicant is not required to identify any grace period inventor-originated public disclosures or to use the format specified in 37 CFR 1.77, but identifying any such disclosures may expedite examination of the application and save applicants (and the Office) the costs related to an Office action and reply. If the patent application specification as filed contains a specific reference to a grace period inventor-originated public disclosure, and an oath or declaration under 37 CFR 1.63 from the inventor or the appropriate joint inventor(s) has been made of record, the Office will consider it apparent from the specification that the grace period public disclosure is attributable to the inventor or a joint inventor, provided there is a sufficient explanation of why the exception applies to a particular disclosure and there is no other evidence to the contrary. The applicant should also provide a copy of the grace period inventor-originated public disclosure (e.g., copy of a printed publication). The format specified in 37 CFR 1.77(b)(6) may not be the basis to add information about inventor-originated grace period public disclosures to the specification after the filing date of the application. Such an amendment may be considered new matter. Applicants should use 37 CFR 1.130(a) to submit such information after filing.

Affidavit Requirement for Establishing Inventor-Originated Disclosure
Note:
Applicant must file an affidavit under 37 CFR 1.130 to establish that a disclosure during the grace period is inventor-originated if not clear from the disclosure itself or the patent application specification.

The Office has provided a mechanism for filing an affidavit or declaration (under 37 CFR 1.130) to establish that a disclosure is not prior art under AIA 35 U.S.C. 102(a) due to an exception in AIA 35 U.S.C. 102(b). See MPEP § 717. In the situations in which it is not apparent from the grace period disclosure itself or the patent application specification that the disclosure is an inventor-originated disclosure, the applicant may establish that the AIA 35 U.S.C. 102(b)(1)(A) exception applies by way of an affidavit or declaration under 37 CFR 1.130(a). MPEP § 2155.01 discusses the use of affidavits or declarations to show that a disclosure was an inventor-originated disclosure made during the grace period.

Evidence for Inventor-Originated Disclosure Required on a Case-by-Case Basis
Note:
The rule requires that evidence showing an inventor-originated disclosure be determined on a case-by-case basis, depending on whether the disclosure itself or the patent application specification indicates such origin.

AIA 35 U.S.C. 102(b)(1)(A) first provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) is excepted as prior art if the disclosure is made: (1) one year or less before the effective filing date of the claimed invention; and (2) by the inventor or a joint inventor or by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor (i.e., an inventor-originated disclosure). Thus, a disclosure that would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) may not be used as prior art by Office personnel if the disclosure is made one year or less before the effective filing date of the claimed invention, and the evidence shows that the disclosure is an inventor-originated disclosure. What evidence is necessary to show that the disclosure is an inventor-originated disclosure requires case-by-case treatment, depending upon whether it is apparent from the disclosure itself or the patent application specification that the disclosure is an inventor-originated disclosure.

Format for Grace Period Disclosures Not Allowed After Filing
Note:
The format specified in 37 CFR 1.77(b)(6) cannot be used to add information about inventor-originated grace period public disclosures after the filing date.

Applicants can include a statement regarding any grace period inventor-originated public disclosures in the specification upon filing. See 37 CFR 1.77(b)(6) and MPEP § 608.01(a). In order to be effective to show that a grace period inventor-originated public disclosure is not prior art under AIA 35 U.S.C. 102(a)(1) because the AIA 35 U.S.C. 102(b)(1)(A) exception applies, the statement must convey the same information as would be required in a declaration under 37 CFR 1.130(a). See MPEP §§ 717.01(a)(1), 2155.01, and 2155.03. An applicant is not required to identify any grace period inventor-originated public disclosures or to use the format specified in 37 CFR 1.77, but identifying any such disclosures may expedite examination of the application and save applicants (and the Office) the costs related to an Office action and reply. If the patent application specification as filed contains a specific reference to a grace period inventor-originated public disclosure, and an oath or declaration under 37 CFR 1.63 from the inventor or the appropriate joint inventor(s) has been made of record, the Office will consider it apparent from the specification that the grace period public disclosure is attributable to the inventor or a joint inventor, provided there is a sufficient explanation of why the exception applies to a particular disclosure and there is no other evidence to the contrary. The applicant should also provide a copy of the grace period inventor-originated public disclosure (e.g., copy of a printed publication).

Disclosure Within Grace Period Not Prior Art If Inventor-Originated
Note:
A disclosure made within one year of the filing date and clearly an inventor-originated disclosure is not considered prior art under AIA 35 U.S.C. 102(a)(1).

A disclosure made within the grace period is not prior art under AIA 35 U.S.C. 102(a)(1) if it is apparent from the disclosure itself that it is an inventor-originated disclosure. Specifically, Office personnel may not apply a disclosure as prior art under AIA 35 U.S.C. 102(a)(1) if the disclosure: (1) was made one year or less before the effective filing date of the claimed invention; (2) names the inventor or a joint inventor as an author or an inventor; and (3) does not name additional persons as authors on a printed publication or joint inventors on a patent. This means that in circumstances where an application names additional persons as joint inventors relative to the persons named as authors in the publication (e.g., the application names as joint inventors A, B, and C, and the publication names as authors A and B), and the publication is one year or less before the effective filing date, it is apparent that the disclosure is a grace period inventor disclosure, and the publication is not prior art under AIA 35 U.S.C. 102(a)(1). If, however, the application names fewer joint inventors than a publication (e.g., the application names as joint inventors A and B, and the publication names as authors A, B and C), it would not be readily apparent from the publication that it is an inventor-originated disclosure and the publication would be treated as prior art under AIA 35 U.S.C. 102(a)(1) unless there is evidence of record that an exception under AIA 35 U.S.C. 102(b)(1) applies.

Application Names Fewer Joint Inventors Than Publication
Note:
If an application names fewer joint inventors than a publication, the publication is treated as prior art unless evidence shows it's a grace period inventor disclosure.

A disclosure made within the grace period is not prior art under AIA 35 U.S.C. 102(a)(1) if it is apparent from the disclosure itself that it is an inventor-originated disclosure. Specifically, Office personnel may not apply a disclosure as prior art under AIA 35 U.S.C. 102(a)(1) if the disclosure: (1) was made one year or less before the effective filing date of the claimed invention; (2) names the inventor or a joint inventor as an author or an inventor; and (3) does not name additional persons as authors on a printed publication or joint inventors on a patent. This means that in circumstances where an application names additional persons as joint inventors relative to the persons named as authors in the publication (e.g., the application names as joint inventors A, B, and C, and the publication names as authors A and B), and the publication is one year or less before the effective filing date, it is apparent that the disclosure is a grace period inventor disclosure, and the publication is not prior art under AIA 35 U.S.C. 102(a)(1). If, however, the application names fewer joint inventors than a publication (e.g., the application names as joint inventors A and B, and the publication names as authors A, B and C), it would not be readily apparent from the publication that it is an inventor-originated disclosure and the publication would be treated as prior art under AIA 35 U.S.C. 102(a)(1) unless there is evidence of record that an exception under AIA 35 U.S.C. 102(b)(1) applies.

Disclosure One Year Before Filing Is Excluded If Inventor-Originated
Note:
A disclosure that would otherwise be prior art is excluded if made by the inventor within one year of the filing date and shown to be an inventor-originated disclosure.

AIA 35 U.S.C. 102(b)(1)(A) first provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) is excepted as prior art if the disclosure is made: (1) one year or less before the effective filing date of the claimed invention; and (2) by the inventor or a joint inventor or by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor (i.e., an inventor-originated disclosure).

Disclosure Within One Year Not Prior Art If Inventor-Originated
Note:
Office personnel may not apply a disclosure as prior art if it is made within one year of the filing date and names the inventor or joint inventor without additional authors.

A disclosure made within the grace period is not prior art under AIA 35 U.S.C. 102(a)(1) if it is apparent from the disclosure itself that it is an inventor-originated disclosure. Specifically, Office personnel may not apply a disclosure as prior art under AIA 35 U.S.C. 102(a)(1) if the disclosure: (1) was made one year or less before the effective filing date of the claimed invention; (2) names the inventor or a joint inventor as an author or an inventor; and (3) does not name additional persons as authors on a printed publication or joint inventors on a patent. This means that in circumstances where an application names additional persons as joint inventors relative to the persons named as authors in the publication (e.g., the application names as joint inventors A, B, and C, and the publication names as authors A and B), and the publication is one year or less before the effective filing date, it is apparent that the disclosure is a grace period inventor disclosure, and the publication is not prior art under AIA 35 U.S.C. 102(a)(1).

Note:
Applicants must include a statement in the specification regarding any grace period inventor-originated public disclosures upon filing to potentially avoid prior art under AIA 35 U.S.C. 102(a)(1).

Applicants can include a statement regarding any grace period inventor-originated public disclosures in the specification upon filing. See 37 CFR 1.77(b)(6) and MPEP § 608.01(a).

An amendment adding information about grace period inventor-originated public disclosures may be considered new matter.

Applicants can include a statement regarding any grace period inventor-originated public disclosures in the specification upon filing. See 37 CFR 1.77(b)(6) and MPEP § 608.01(a). In order to be effective to show that a grace period inventor-originated public disclosure is not prior art under AIA 35 U.S.C. 102(a)(1) because the AIA 35 U.S.C. 102(b)(1)(A) exception applies, the statement must convey the same information as would be required in a declaration under 37 CFR 1.130(a). See MPEP §§ 717.01(a)(1), 2155.01, and 2155.03. An applicant is not required to identify any grace period inventor-originated public disclosures or to use the format specified in 37 CFR 1.77, but identifying any such disclosures may expedite examination of the application and save applicants (and the Office) the costs related to an Office action and reply. If the patent application specification as filed contains a specific reference to a grace period inventor-originated public disclosure, and an oath or declaration under 37 CFR 1.63 from the inventor or the appropriate joint inventor(s) has been made of record, the Office will consider it apparent from the specification that the grace period public disclosure is attributable to the inventor or a joint inventor, provided there is a sufficient explanation of why the exception applies to a particular disclosure and there is no other evidence to the contrary. The applicant should also provide a copy of the grace period inventor-originated public disclosure (e.g., copy of a printed publication). The format specified in 37 CFR 1.77(b)(6) may not be the basis to add information about inventor-originated grace period public disclosures to the specification after the filing date of the application. Such an amendment may be considered new matter. Applicants should use 37 CFR 1.130(a) to submit such information after filing.
