What is the one-year grace period for inventor-originated disclosures?

The one-year grace period for inventor-originated disclosures is a provision in the America Invents Act (AIA) that allows inventors to disclose their inventions up to one year before filing a patent application without those disclosures being considered prior art against their own applications. MPEP 2153.01(a) states:

“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).”

It’s important to note that the grace period is extended to the next business day if it falls on a weekend or federal holiday: “The one-year grace period in AIA 35 U.S.C. 102(b)(1)(A) is extended to the next succeeding business day if the end of the one-year grace period otherwise falls on a Saturday, Sunday, or federal holiday. Ex parte Olah, 131 USPQ 41 (Bd. App. 1960) and 35 U.S.C. 21(b).”
