2136 Pre-AIA 35 U.S.C. 102(e)
This section covers pre-AIA 35 U.S.C. 102(e). 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 section includes a discussion on how statutory invention registrations are eligible as prior art under 35 U.S.C. 102 and pre-AIA 35 U.S.C. 102(e). In addition, defensive publications are not prior art as of their filing date. It is only prior art as of its publication date.
