Disclosure by Inventor Within One Year Exceptions Prior Art
Note:
This rule excepts from prior art disclosures made within one year of the filing date if they were publicly disclosed by the inventor or a joint inventor.

AIA 35 U.S.C. 102(b)(1)(B) provides an additional exception to the prior art provision of AIA 35 U.S.C. 102(a)(1). AIA 35 U.S.C. 102(b)(1)(B) excepts as prior art a disclosure of subject matter that occurs after the subject matter had been publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor (i.e., an inventor-originated public disclosure). Specifically, AIA 35 U.S.C. 102(b)(1)(B) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) (patent, printed publication, public use, sale, or other means of public availability) is excepted as prior art if: (1) the disclosure was made one year or less before the effective filing date of the claimed invention; and (2) the subject matter disclosed had been previously publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor. The previous inventor-originated public disclosure of the subject matter typically will be a disclosure within the one-year grace period (i.e., a grace period inventor-originated disclosure). However, if the previous inventor-originated public disclosure of the subject matter was made outside the grace period, that disclosure itself would qualify as prior art under AIA 35 U.S.C. 102(a)(1), and could not be excepted under AIA 35 U.S.C. 102(b)(1)(A). In other words, a previous inventor-originated public disclosure of the subject matter can be effective to establish that a grace period disclosure is excepted as prior art regardless of whether the previous inventor-originated disclosure was made within the grace period or not. MPEP § 2152.01 discusses the “effective filing date” of a claimed invention. MPEP § 2155.02 discusses the use of affidavits or declarations to show that the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor, and MPEP § 2155.03 discusses the use of affidavits or declarations to show that the disclosure was made, or that the subject matter had been previously publicly disclosed, by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.

Disclosure Outside Grace Period Qualifies as Prior Art
Note:
If an inventor-originated public disclosure of subject matter is made outside the grace period, it qualifies as prior art and cannot be excepted under AIA 35 U.S.C. 102(b)(1)(A).

AIA 35 U.S.C. 102(b)(1)(B) provides an additional exception to the prior art provision of AIA 35 U.S.C. 102(a)(1). AIA 35 U.S.C. 102(b)(1)(B) excepts as prior art a disclosure of subject matter that occurs after the subject matter had been publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor (i.e., an inventor-originated public disclosure). Specifically, AIA 35 U.S.C. 102(b)(1)(B) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) (patent, printed publication, public use, sale, or other means of public availability) is excepted as prior art if: (1) the disclosure was made one year or less before the effective filing date of the claimed invention; and (2) the subject matter disclosed had been previously publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor. The previous inventor-originated public disclosure of the subject matter typically will be a disclosure within the one-year grace period (i.e., a grace period inventor-originated disclosure). However, if the previous inventor-originated public disclosure of the subject matter was made outside the grace period, that disclosure itself would qualify as prior art under AIA 35 U.S.C. 102(a)(1), and could not be excepted under AIA 35 U.S.C. 102(b)(1)(A). In other words, a previous inventor-originated public disclosure of the subject matter can be effective to establish that a grace period disclosure is excepted as prior art regardless of whether the previous inventor-originated disclosure was made within the grace period or not. MPEP § 2152.01 discusses the “effective filing date” of a claimed invention.

Grace Period Disclosure Excepts Prior Art Regardless of Timing
Note:
A previous inventor-originated public disclosure can establish that a subsequent disclosure is excepted as prior art, even if the initial disclosure was outside the grace period.

AIA 35 U.S.C. 102(b)(1)(B) provides an additional exception to the prior art provision of AIA 35 U.S.C. 102(a)(1). AIA 35 U.S.C. 102(b)(1)(B) excepts as prior art a disclosure of subject matter that occurs after the subject matter had been publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor (i.e., an inventor-originated public disclosure). Specifically, AIA 35 U.S.C. 102(b)(1)(B) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) (patent, printed publication, public use, sale, or other means of public availability) is excepted as prior art if: (1) the disclosure was made one year or less before the effective filing date of the claimed invention; and (2) the subject matter disclosed had been previously publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor. The previous inventor-originated public disclosure of the subject matter typically will be a disclosure within the one-year grace period (i.e., a grace period inventor-originated disclosure). However, if the previous inventor-originated public disclosure of the subject matter was made outside the grace period, that disclosure itself would qualify as prior art under AIA 35 U.S.C. 102(a)(1), and could not be excepted under AIA 35 U.S.C. 102(b)(1)(A). In other words, a previous inventor-originated public disclosure of the subject matter can be effective to establish that a grace period disclosure is excepted as prior art regardless of whether the previous inventor-originated disclosure was made within the grace period or not. MPEP § 2152.01 discusses the “effective filing date” of a claimed invention.

Disclosure Method Not Restricted
Note:
The mode of disclosure by the inventor or joint inventor does not need to match the mode of the intervening grace period disclosure.

There is no requirement under AIA 35 U.S.C. 102(b)(1)(B) that the mode of disclosure by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor) be the same as the mode of disclosure of the intervening grace period disclosure (e.g., patenting, publication, public use, sale activity). There is also no requirement that the disclosure by the inventor or a joint inventor be a verbatim or ipsissimis verbis disclosure of the intervening grace period disclosure. See In re Kao, 639 F.3d 1057, 1066 98 USPQ2d 1799, 1806 (Fed. Cir. 2011) (subject matter does not change as a function of how one chooses to describe it). What is required for subject matter in an intervening grace period disclosure to be excepted under AIA 35 U.S.C. 102(b)(1)(B) is that the same subject matter as in the intervening disclosure must have been previously publicly disclosed by the inventor or a joint inventor (or by another who obtained the subject matter therefrom).

Note:
The mode of disclosure by the inventor does not need to match the intervening grace period disclosure for it to be excepted under AIA 35 U.S.C. 102(b)(1)(B).

There is no requirement under AIA 35 U.S.C. 102(b)(1)(B) that the mode of disclosure by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor) be the same as the mode of disclosure of the intervening grace period disclosure (e.g., patenting, publication, public use, sale activity).

Intervening Grace Period Disclosure Not Inventing Origin Prior Public Disclosure Is Prior Art
Note:
An intervening grace period disclosure that is not from the inventor's prior public disclosure can still be considered prior art under AIA 35 U.S.C. 102(a)(1).

The exception in AIA 35 U.S.C. 102(b)(1)(B) applies to the subject matter in the intervening grace period disclosure being relied upon as prior art for a rejection under AIA 35 U.S.C. 102(a)(1) (an intervening disclosure) that was also publicly disclosed by the inventor or a joint inventor (or by another who obtained the subject matter therefrom) before such intervening disclosure. The subject matter of an intervening grace period disclosure that is not in the inventor-originated prior public disclosure is available as prior art under AIA 35 U.S.C. 102(a)(1). For example, if the inventor or a joint inventor had publicly disclosed A, B, and C, and a subsequent intervening grace period disclosure discloses A, B, C, and D, then D remains available as prior art under AIA 35 U.S.C. 102(a)(1) even though the AIA 35 U.S.C. 102(b)(1)(B) exception applies such that A, B, and C are not prior art. In other words, the exception in AIA 35 U.S.C. 102(b)(1)(B) does not necessarily remove the entire disclosure in the intervening reference from being prior art.

Intervening Grace Period Disclosure Does Not Exclude Entire Disclosure from Prior Art
Note:
If an inventor publicly disclosed A, B, and C, and a subsequent intervening grace period disclosure includes A, B, C, and D, then D remains prior art even though the exception in AIA 35 U.S.C. 102(b)(1)(B) applies to A, B, and C.

The exception in AIA 35 U.S.C. 102(b)(1)(B) applies to the subject matter in the intervening grace period disclosure being relied upon as prior art for a rejection under AIA 35 U.S.C. 102(a)(1) (an intervening disclosure) that was also publicly disclosed by the inventor or a joint inventor (or by another who obtained the subject matter therefrom) before such intervening disclosure.

Intervening Disclosure Can Still Be Prior Art
Note:
An intervening disclosure that is not part of the inventor-originated prior public disclosure can still be considered prior art even if it contains subject matter covered by AIA 35 U.S.C. 102(b)(1)(B).

The exception in AIA 35 U.S.C. 102(b)(1)(B) applies to the subject matter in the intervening grace period disclosure being relied upon as prior art for a rejection under AIA 35 U.S.C. 102(a)(1) (an intervening disclosure) that was also publicly disclosed by the inventor or a joint inventor (or by another who obtained the subject matter therefrom) before such intervening disclosure.

Intervening Grace Period Disclosure Must Not Be More General Than Prior Public Disclosure
Note:
An intervening grace period disclosure cannot be more general than an inventor-originated prior public disclosure to qualify for the AIA 35 U.S.C. 102(b)(1)(B) exception.

In addition, if subject matter of an intervening grace period disclosure is simply a more general description of the subject matter in an inventor-originated prior public disclosure, the exception in AIA 35 U.S.C. 102(b)(1)(B) applies to such subject matter of the intervening grace period disclosure. To hold otherwise would unfairly deprive an inventor of a patent merely because a third party became aware of the inventor’s public disclosure and then publicized a genericized version of it. For example, if the inventor or a joint inventor had publicly disclosed a species, and a subsequent intervening grace period disclosure discloses a genus (i.e., provides a more generic disclosure of the species), the intervening grace period disclosure of the genus is not available as prior art under AIA 35 U.S.C. 102(a)(1). Conversely, if the inventor or a joint inventor had publicly disclosed a genus, and a subsequent intervening grace period disclosure discloses a species, the intervening grace period disclosure of the species would be available as prior art under AIA 35 U.S.C. 102(a)(1). Likewise, if the inventor or a joint inventor had publicly disclosed a species, and a subsequent intervening grace period disclosure discloses an alternative species not also disclosed by the inventor or a joint inventor, the intervening grace period disclosure of the alternative species would be available as prior art under AIA 35 U.S.C. 102(a)(1) because the “subject matter disclosed” requirement of AIA 35 U.S.C. 102(b)(1)(B) would not have been met.

Intervening Grace Period Genus Not Prior Art
Note:
If a species was publicly disclosed and later a genus is disclosed during the grace period, it does not serve as prior art under AIA 35 U.S.C. 102(a)(1).

In addition, if subject matter of an intervening grace period disclosure is simply a more general description of the subject matter in an inventor-originated prior public disclosure, the exception in AIA 35 U.S.C. 102(b)(1)(B) applies to such subject matter of the intervening grace period disclosure.

Subsequent Species Disclosure as Prior Art After Public Genus Disclosure
Note:
If a genus was publicly disclosed by the inventor and later a species is disclosed during an intervening grace period, that species disclosure can be used as prior art under AIA 35 U.S.C. 102(a)(1).

In addition, if subject matter of an intervening grace period disclosure is simply a more general description of the subject matter in an inventor-originated prior public disclosure, the exception in AIA 35 U.S.C. 102(b)(1)(B) applies to such subject matter of the intervening grace period disclosure. To hold otherwise would unfairly deprive an inventor of a patent merely because a third party became aware of the inventor’s public disclosure and then publicized a genericized version of it.

Use of Affidavits to Prove Prior Public Disclosures by Inventors
Note:
The rule explains how affidavits or declarations can be used to show that an inventor publicly disclosed the subject matter before a patent application was filed.

AIA 35 U.S.C. 102(b)(1)(B) provides an additional exception to the prior art provision of AIA 35 U.S.C. 102(a)(1). AIA 35 U.S.C. 102(b)(1)(B) excepts as prior art a disclosure of subject matter that occurs after the subject matter had been publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor (i.e., an inventor-originated public disclosure). Specifically, AIA 35 U.S.C. 102(b)(1)(B) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) (patent, printed publication, public use, sale, or other means of public availability) is excepted as prior art if: (1) the disclosure was made one year or less before the effective filing date of the claimed invention; and (2) the subject matter disclosed had been previously publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor. The previous inventor-originated public disclosure of the subject matter typically will be a disclosure within the one-year grace period (i.e., a grace period inventor-originated disclosure). However, if the previous inventor-originated public disclosure of the subject matter was made outside the grace period, that disclosure itself would qualify as prior art under AIA 35 U.S.C. 102(a)(1), and could not be excepted under AIA 35 U.S.C. 102(b)(1)(A). In other words, a previous inventor-originated public disclosure of the subject matter can be effective to establish that a grace period disclosure is excepted as prior art regardless of whether the previous inventor-originated disclosure was made within the grace period or not. MPEP § 2152.01 discusses the “effective filing date” of a claimed invention. MPEP § 2155.02 discusses the use of affidavits or declarations to show that the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor, and MPEP § 2155.03 discusses the use of affidavits or declarations to show that the disclosure was made, or that the subject matter had been previously publicly disclosed, by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.

Subject Matter Must Be Publicly Disclosed by Inventor
Note:
The same subject matter as in an intervening grace period disclosure must have been publicly disclosed by the inventor or a joint inventor (or someone who obtained it from them).

There is no requirement under AIA 35 U.S.C. 102(b)(1)(B) that the mode of disclosure by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor) be the same as the mode of disclosure of the intervening grace period disclosure (e.g., patenting, publication, public use, sale activity). There is also no requirement that the disclosure by the inventor or a joint inventor be a verbatim or ipsissimis verbis disclosure of the intervening grace period disclosure. See In re Kao, 639 F.3d 1057, 1066 98 USPQ2d 1799, 1806 (Fed. Cir. 2011) (subject matter does not change as a function of how one chooses to describe it).

Grace Period Intervening Disclosure Exception
Note:
Subject matter from an inventor-originated public disclosure in the intervening grace period remains prior art even if part of a later disclosure is excluded by AIA 35 U.S.C. 102(b)(1)(B).

The exception in AIA 35 U.S.C. 102(b)(1)(B) applies to the subject matter in the intervening grace period disclosure being relied upon as prior art for a rejection under AIA 35 U.S.C. 102(a)(1) (an intervening disclosure) that was also publicly disclosed by the inventor or a joint inventor (or by another who obtained the subject matter therefrom) before such intervening disclosure. The subject matter of an intervening grace period disclosure that is not in the inventor-originated prior public disclosure is available as prior art under AIA 35 U.S.C. 102(a)(1). For example, if the inventor or a joint inventor had publicly disclosed A, B, and C, and a subsequent intervening grace period disclosure discloses A, B, C, and D, then D remains available as prior art under AIA 35 U.S.C. 102(a)(1) even though the AIA 35 U.S.C. 102(b)(1)(B) exception applies such that A, B, and C are not prior art. In other words, the exception in AIA 35 U.S.C. 102(b)(1)(B) does not necessarily remove the entire disclosure in the intervening reference from being prior art.

Inventor-Originated Public Disclosure Exception
Note:
This rule prevents an inventor from losing patent rights due to a third party publicizing a genericized version of their prior disclosure.

In addition, if subject matter of an intervening grace period disclosure is simply a more general description of the subject matter in an inventor-originated prior public disclosure, the exception in AIA 35 U.S.C. 102(b)(1)(B) applies to such subject matter of the intervening grace period disclosure. To hold otherwise would unfairly deprive an inventor of a patent merely because a third party became aware of the inventor’s public disclosure and then publicized a genericized version of it. For example, if the inventor or a joint inventor had publicly disclosed a species, and a subsequent intervening grace period disclosure discloses a genus (i.e., provides a more generic disclosure of the species), the intervening grace period disclosure of the genus is not available as prior art under AIA 35 U.S.C. 102(a)(1). Conversely, if the inventor or a joint inventor had publicly disclosed a genus, and a subsequent intervening grace period disclosure discloses a species, the intervening grace period disclosure of the species would be available as prior art under AIA 35 U.S.C. 102(a)(1). Likewise, if the inventor or a joint inventor had publicly disclosed a species, and a subsequent intervening grace period disclosure discloses an alternative species not also disclosed by the inventor or a joint inventor, the intervening grace period disclosure of the alternative species would be available as prior art under AIA 35 U.S.C. 102(a)(1) because the “subject matter disclosed” requirement of AIA 35 U.S.C. 102(b)(1)(B) would not have been met.

Alternative Species Disclosed During Grace Period
Note:
If an inventor publicly disclosed a species and a subsequent disclosure during the grace period discloses an alternative species not previously disclosed, that alternative species is prior art.

In addition, if subject matter of an intervening grace period disclosure is simply a more general description of the subject matter in an inventor-originated prior public disclosure, the exception in AIA 35 U.S.C. 102(b)(1)(B) applies to such subject matter of the intervening grace period disclosure. To hold otherwise would unfairly deprive an inventor of a patent merely because a third party became aware of the inventor’s public disclosure and then publicized a genericized version of it. For example, if the inventor or a joint inventor had publicly disclosed a species, and a subsequent intervening grace period disclosure discloses a genus (i.e., provides a more generic disclosure of the species), the intervening grace period disclosure of the genus is not available as prior art under AIA 35 U.S.C. 102(a)(1).

Intervening Grace Period Disclosure Does Not Affect Claimed Invention Determination
Note:
The determination of whether the exception in AIA 35 U.S.C. 102(b)(1)(B) applies does not involve comparing the claimed invention to prior public disclosures.

Finally, AIA 35 U.S.C. 102(b)(1)(B) does not discuss “the claimed invention” with respect to either the subject matter disclosed by the inventor or a joint inventor, or the subject matter of the subsequent intervening grace period disclosure. The only inquiry with respect to the claimed invention is whether or not the subject matter in the prior art disclosure being relied upon anticipates or renders obvious the claimed invention. A determination of whether the exception in AIA 35 U.S.C. 102(b)(1)(B) is applicable to subject matter in an intervening grace period disclosure does not involve a comparison of the subject matter of the claimed invention to either the subject matter in the inventor-originated prior public disclosure, or to the subject matter of the subsequent intervening grace period disclosure.

Disclosure by Inventor Within One Year Is Not Prior Art
Note:
This rule states that a disclosure made by an inventor within one year of the filing date does not count as prior art if it was publicly disclosed before by the same inventor.

AIA 35 U.S.C. 102(b)(1)(B) provides an additional exception to the prior art provision of AIA 35 U.S.C. 102(a)(1). AIA 35 U.S.C. 102(b)(1)(B) excepts as prior art a disclosure of subject matter that occurs after the subject matter had been publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor (i.e., an inventor-originated public disclosure). Specifically, AIA 35 U.S.C. 102(b)(1)(B) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) (patent, printed publication, public use, sale, or other means of public availability) is excepted as prior art if: (1) the disclosure was made one year or less before the effective filing date of the claimed invention; and (2) the subject matter disclosed had been previously publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor. The previous inventor-originated public disclosure of the subject matter typically will be a disclosure within the one-year grace period (i.e., a grace period inventor-originated disclosure). However, if the previous inventor-originated public disclosure of the subject matter was made outside the grace period, that disclosure itself would qualify as prior art under AIA 35 U.S.C. 102(a)(1), and could not be excepted under AIA 35 U.S.C. 102(b)(1)(A). In other words, a previous inventor-originated public disclosure of the subject matter can be effective to establish that a grace period disclosure is excepted as prior art regardless of whether the previous inventor-originated disclosure was made within the grace period or not. MPEP § 2152.01 discusses the “effective filing date” of a claimed invention. MPEP § 2155.02 discusses the use of affidavits or declarations to show that the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor, and MPEP § 2155.03 discusses the use of affidavits or declarations to show that the disclosure was made, or that the subject matter had been previously publicly disclosed, by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.

The exception in AIA 35 U.S.C. 102(b)(1)(B) focuses on the “subject matter” that had been previously publicly disclosed by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor). The subject matter in the prior disclosure being relied upon under AIA 35 U.S.C. 102(a) must be the same "subject matter" as the subject matter previously publicly disclosed by the inventor for the exceptions in AIA 35 U.S.C. 102(b)(1)(B) and AIA 102(b)(2)(B) to apply. The exceptions in AIA 35 U.S.C. 102(b)(1)(B) and AIA 102(b)(2)(B) do not apply even if the only differences between the subject matter in the prior art disclosure that is relied upon under AIA 35 U.S.C. 102(a) and the subject matter previously publicly disclosed by the inventor are mere insubstantial changes, or only trivial or obvious variations. This guidance maintains the identical subject matter interpretation of AIA 35 U.S.C. 102(b)(1)(B) and AIA 102(b)(2)(B).

Effective Filing Date of Invention
Note:
MPEP § 2152.01 explains how to determine the effective filing date for a claimed invention under AIA 35 U.S.C. 102(b)(1)(B).

AIA 35 U.S.C. 102(b)(1)(B) provides an additional exception to the prior art provision of AIA 35 U.S.C. 102(a)(1). AIA 35 U.S.C. 102(b)(1)(B) excepts as prior art a disclosure of subject matter that occurs after the subject matter had been publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor (i.e., an inventor-originated public disclosure). Specifically, AIA 35 U.S.C. 102(b)(1)(B) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) (patent, printed publication, public use, sale, or other means of public availability) is excepted as prior art if: (1) the disclosure was made one year or less before the effective filing date of the claimed invention; and (2) the subject matter disclosed had been previously publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor. The previous inventor-originated public disclosure of the subject matter typically will be a disclosure within the one-year grace period (i.e., a grace period inventor-originated disclosure). However, if the previous inventor-originated public disclosure of the subject matter was made outside the grace period, that disclosure itself would qualify as prior art under AIA 35 U.S.C. 102(a)(1), and could not be excepted under AIA 35 U.S.C. 102(b)(1)(A). In other words, a previous inventor-originated public disclosure of the subject matter can be effective to establish that a grace period disclosure is excepted as prior art regardless of whether the previous inventor-originated disclosure was made within the grace period or not. MPEP § 2152.01 discusses the “effective filing date” of a claimed invention. MPEP § 2155.02 discusses the use of affidavits or declarations to show that the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor, and MPEP § 2155.03 discusses the use of affidavits or declarations to show that the disclosure was made, or that the subject matter had been previously publicly disclosed, by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.

Note:
The specification must describe any inventor-originated public disclosures made before a potential AIA 35 U.S.C. 102(a)(1) disclosure of the same subject matter, using information equivalent to what would be required in a declaration under 37 CFR 1.130(b).

Applicants can include a statement in the specification upon filing regarding any inventor-originated public disclosures of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter. See 37 CFR 1.77(b)(6) and MPEP § 608.01(a). In order to be effective to show that a potential AIA 35 U.S.C. 102(a)(1) disclosure of subject matter is not prior art under AIA 35 U.S.C. 102(a)(1) because the AIA 35 U.S.C. 102(b)(1)(B) exception applies, the statement must convey the same information as would be required in a declaration under 37 CFR 1.130(b). See MPEP §§ 717.01(b)(1), 2155.02, and 2155.03. An applicant is not required to identify any inventor-originated public disclosures of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter, or to use the format specified in 37 CFR 1.77(b)(6), but identifying any such public 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 an inventor-originated public disclosure of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter, 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 potential AIA 35 U.S.C. 102(a)(1) disclosure of the same subject matter is not, in fact, prior art under AIA 35 U.S.C. 102(a)(1), 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 must also provide a copy of the prior inventor-originated public disclosure if it was made by way of a printed publication; see 37 CFR 1.130(b). Applicants may not use 37 CFR 1.77(b)(6) to add information to the specification about inventor-originated public disclosures of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter after the date that the application is filed. Applicants should use 37 CFR 1.130(b) to submit such information after filing.

Disclosure by Inventor Within One Year Is Excepted as Prior Art
Note:
A disclosure made within one year before the effective filing date and publicly disclosed by an inventor is excepted from being prior art under AIA 35 U.S.C. 102(a)(1).

AIA 35 U.S.C. 102(b)(1)(B) provides an additional exception to the prior art provision of AIA 35 U.S.C. 102(a)(1). AIA 35 U.S.C. 102(b)(1)(B) excepts as prior art a disclosure of subject matter that occurs after the subject matter had been publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor (i.e., an inventor-originated public disclosure). Specifically, AIA 35 U.S.C. 102(b)(1)(B) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) (patent, printed publication, public use, sale, or other means of public availability) is excepted as prior art if: (1) the disclosure was made one year or less before the effective filing date of the claimed invention; and (2) the subject matter disclosed had been previously publicly disclosed by the inventor, a joint inventor, or another who obtained the subject matter directly or indirectly from the inventor or joint inventor. The previous inventor-originated public disclosure of the subject matter typically will be a disclosure within the one-year grace period (i.e., a grace period inventor-originated disclosure). However, if the previous inventor-originated public disclosure of the subject matter was made outside the grace period, that disclosure itself would qualify as prior art under AIA 35 U.S.C. 102(a)(1), and could not be excepted under AIA 35 U.S.C. 102(b)(1)(A). In other words, a previous inventor-originated public disclosure of the subject matter can be effective to establish that a grace period disclosure is excepted as prior art regardless of whether the previous inventor-originated disclosure was made within the grace period or not. MPEP § 2152.01 discusses the “effective filing date” of a claimed invention. MPEP § 2155.02 discusses the use of affidavits or declarations to show that the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor, and MPEP § 2155.03 discusses the use of affidavits or declarations to show that the disclosure was made, or that the subject matter had been previously publicly disclosed, by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.

Mode of Disclosure Not Required to Match Grace Period
Note:
The mode of disclosure by the inventor does not need to match the mode of disclosure in an intervening grace period for it to be excepted under AIA 35 U.S.C. 102(b)(1)(B).

There is no requirement under AIA 35 U.S.C. 102(b)(1)(B) that the mode of disclosure by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor) be the same as the mode of disclosure of the intervening grace period disclosure (e.g., patenting, publication, public use, sale activity). There is also no requirement that the disclosure by the inventor or a joint inventor be a verbatim or ipsissimis verbis disclosure of the intervening grace period disclosure. See In re Kao, 639 F.3d 1057, 1066 98 USPQ2d 1799, 1806 (Fed. Cir. 2011) (subject matter does not change as a function of how one chooses to describe it). What is required for subject matter in an intervening grace period disclosure to be excepted under AIA 35 U.S.C. 102(b)(1)(B) is that the same subject matter as in the intervening disclosure must have been previously publicly disclosed by the inventor or a joint inventor (or by another who obtained the subject matter therefrom).

Subject Matter Previously Disclosed by Inventor Must Match Prior Art
Note:
The exception under AIA 35 U.S.C. 102(b)(1)(B) applies only if the subject matter in prior art matches what was publicly disclosed by the inventor before any intervening disclosure.

The exception in AIA 35 U.S.C. 102(b)(1)(B) applies if the “subject matter disclosed [in the intervening disclosure] had, before such [intervening] disclosure, been publicly disclosed by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor).” See AIA 35 U.S.C. 102(b)(1)(B). The exception in AIA 35 U.S.C. 102(b)(1)(B) focuses on the “subject matter” that had been previously publicly disclosed by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor). The subject matter in the prior disclosure being relied upon under AIA 35 U.S.C. 102(a) must be the same "subject matter" as the subject matter previously publicly disclosed by the inventor for the exceptions in AIA 35 U.S.C. 102(b)(1)(B) and AIA 102(b)(2)(B) to apply. The exceptions in AIA 35 U.S.C. 102(b)(1)(B) and AIA 102(b)(2)(B) do not apply even if the only differences between the subject matter in the prior art disclosure that is relied upon under AIA 35 U.S.C. 102(a) and the subject matter previously publicly disclosed by the inventor are mere insubstantial changes, or only trivial or obvious variations. This guidance maintains the identical subject matter interpretation of AIA 35 U.S.C. 102(b)(1)(B) and AIA 102(b)(2)(B).

Prior Public Disclosure Must Match Subject Matter
Note:
The subject matter in the prior public disclosure must be identical to that previously disclosed by the inventor for exceptions under AIA 35 U.S.C. 102(b)(1)(B) and 102(b)(2)(B) to apply.

The exception in AIA 35 U.S.C. 102(b)(1)(B) applies if the “subject matter disclosed [in the intervening disclosure] had, before such [intervening] disclosure, been publicly disclosed by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor).” See AIA 35 U.S.C. 102(b)(1)(B).

Disclosure of Inventor-Originated Public Disclosures Required in Specification
Note:
Applicants must include a statement in the specification upon filing regarding any inventor-originated public disclosures made before a potential AIA 35 U.S.C. 102(a)(1) disclosure to show it is not prior art.

Applicants can include a statement in the specification upon filing regarding any inventor-originated public disclosures of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter. See 37 CFR 1.77(b)(6) and MPEP § 608.01(a). In order to be effective to show that a potential AIA 35 U.S.C. 102(a)(1) disclosure of subject matter is not prior art under AIA 35 U.S.C. 102(a)(1) because the AIA 35 U.S.C. 102(b)(1)(B) exception applies, the statement must convey the same information as would be required in a declaration under 37 CFR 1.130(b). See MPEP §§ 717.01(b)(1), 2155.02, and 2155.03. An applicant is not required to identify any inventor-originated public disclosures of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter, or to use the format specified in 37 CFR 1.77(b)(6), but identifying any such public 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 an inventor-originated public disclosure of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter, 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 potential AIA 35 U.S.C. 102(a)(1) disclosure of the same subject matter is not, in fact, prior art under AIA 35 U.S.C. 102(a)(1), 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 must also provide a copy of the prior inventor-originated public disclosure if it was made by way of a printed publication; see 37 CFR 1.130(b). Applicants may not use 37 CFR 1.77(b)(6) to add information to the specification about inventor-originated public disclosures of subject matter made prior to a potential AIA 35 U.S.C. 102(a)(1) disclosure of that same subject matter after the date that the application is filed. Applicants should use 37 CFR 1.130(b) to submit such information after filing.

The exceptions in AIA 35 U.S.C. 102(b)(1)(B) and AIA 102(b)(2)(B) do not apply even if the differences between the prior art disclosure and previously disclosed subject matter are only trivial or obvious variations.

The exception in AIA 35 U.S.C. 102(b)(1)(B) applies if the “subject matter disclosed [in the intervening disclosure] had, before such [intervening] disclosure, been publicly disclosed by the inventor or a joint inventor (or another who obtained the subject matter directly or indirectly from the inventor or joint inventor).” See AIA 35 U.S.C. 102(b)(1)(B).
