What is the grace period disclosure exception under AIA 35 U.S.C. 102(b)(1)(A)?

The grace period disclosure exception under AIA 35 U.S.C. 102(b)(1)(A) provides that a disclosure made within the grace period shall not be considered prior art under AIA 35 U.S.C. 102(a)(1) if the disclosure was made by another who obtained the subject matter directly or indirectly from the inventor or a joint inventor.

As stated in the MPEP: 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. This exception allows inventors to share their inventions with others during the grace period without risking loss of patent rights.
