Ninth Edition, Revision 01.2024 · last revised R-01.2024

[Editor Note: This MPEP section is only applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2131-MPEP § 2138 for examination of applications subject to pre-AIA 35 U.S.C. 102.]

AIA 35 U.S.C. 102(b)(1)(A) and 102(b)(2)(A) provide similar treatment for disclosures of subject matter by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor. Specifically, AIA 35 U.S.C. 102(b)(1)(A) 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 the disclosure was made by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor, and AIA 35 U.S.C. 102(b)(2)(A) 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 was obtained directly or indirectly from the inventor or a joint inventor.

In addition, AIA 35 U.S.C. 102(b)(1)(B) and 102(b)(2)(B) respectively provide that a grace period disclosure under AIA 35 U.S.C. 102(a)(1), and that a disclosure under AIA 35 U.S.C. 102(a)(2) shall not be prior art to a claimed invention, if the subject matter disclosed had, before such grace period disclosure was made under AIA 35 U.S.C. 102(a)(1) or before such subject matter was effectively filed according to 35 U.S.C. 102(a)(2), been publicly disclosed by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor. An applicant may also show that another obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor in an affidavit or declaration under 37 CFR 1.130(b). Thus, an applicant may establish a prior public disclosure by another if the applicant can establish that subject matter disclosed originated with the inventor or a joint inventor and that the subject matter was communicated by the inventor or a joint inventor, directly or indirectly. Any documentation which provides evidence of the communication of the subject matter by the inventor or a joint inventor to the entity that made the disclosure of the subject matter directly or indirectly, such as by an assignee of the inventor, should accompany the affidavit or declaration.
