What is the time frame for the grace period inventor-originated disclosure exception?

The grace period inventor-originated disclosure exception applies to disclosures made one year or less before the effective filing date of the claimed invention. Importantly, the MPEP notes:

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).

This extension applies regardless of the filing method used, including Priority Mail Express® or the USPTO patent electronic filing system.
