Determining Effective Filing Date for AIA Provisions
Note:
The rule explains how to determine the effective filing date of a claimed invention when applying either AIA or pre-AIA provisions.

Because the changes to 35 U.S.C. 102 and 35 U.S.C. 103 in the AIA apply only to specific applications filed on or after March 16, 2013, determining the effective filing date of a claimed invention for purposes of applying AIA 35 U.S.C. 102 and 103 provisions or pre-AIA 35 U.S.C. 102 and 103 provisions is critical.
