2153.01    Prior Art Exception Under AIA 35 U.S.C. 102(b)(1)(A) To AIA 35 U.S.C. 102(a)(1) (Grace Period Inventor Or Inventor-Originated Disclosure Exception) [R-11.2013]

[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) provides exceptions to the prior art provisions of AIA 35 U.S.C. 102(a)(1). These exceptions limit the use of an inventor's own work as prior art, when the inventor's own work has 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 not more than one year before the effective filing date of the claimed invention. AIA 35 U.S.C. 102(b)(1)(A) provides that a disclosure which would otherwise qualify as prior art under AIA 35 U.S.C. 102(a)(1) is not prior art if the disclosure was 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 directly or indirectly from the inventor or joint inventor. MPEP § 2153.01(a) discusses issues pertaining to disclosures within the grace period by the inventor or a joint inventor ("grace period inventor disclosures") and MPEP § 2153.01(b) discusses issues pertaining to disclosures within the grace period by another who obtained the subject matter directly or indirectly from the inventor or joint inventor ("grace period inventor-originated disclosures"). MPEP § 2152.01 discusses the "effective filing date" of a claimed invention.
