37 CFR 1.130(b) provides that when any claim of an application or a patent under reexamination is rejected, the applicant or patent owner may submit an appropriate affidavit or declaration to disqualify a disclosure as prior art by establishing that the subject matter disclosed had, before such disclosure was made or before such subject matter was effectively filed, been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor. 37 CFR 1.130(b) pertains to the provisions of subparagraph (B) of 35 U.S.C. 102(b)(1) and 102(b)(2). 35 U.S.C. 102(b)(1)(B) provides that a disclosure made one year or less before the effective filing date of a claimed invention shall not be prior art to the claimed invention under 35 U.S.C. 102(a)(1) if the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor. 35 U.S.C. 102(b)(2)(B) provides that a disclosure shall not be prior art to a claimed invention under 35 U.S.C. 102(a)(2) if the subject matter disclosed had, before such subject matter was effectively filed under 35 U.S.C. 102(a)(2), been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.
