What is the significance of pre-AIA 35 U.S.C. 102(e) in patent law?

Pre-AIA 35 U.S.C. 102(e) is a crucial provision in patent law that allows certain international application publications, U.S. patent application publications, and U.S. patents to be used as prior art. The MPEP states:

“Pre-AIA 35 U.S.C. 102(e) allows the use of certain international application publications and U.S. patent application publications, and certain U.S. patents as prior art under pre-AIA 35 U.S.C. 102(e) as of their respective U.S. filing dates, including certain international filing dates.”

This provision is particularly important when the publication or issue date of a reference is too recent to be applied under pre-AIA 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(b).
