What is the effective filing date for benefit claims under 35 U.S.C. 386(c) in AIA applications?
For determining the effective filing date under AIA 35 U.S.C. 100(i)(1)(B) with regard to a benefit claim under 35 U.S.C. 386(c) to a prior-filed international design application designating the United States, the U.S. filing date of the international design application should be used, rather than the international filing date, if they are different.
The MPEP states: For purposes of determining the effective filing date under AIA 35 U.S.C. 100(i)(1)(B) with regard to a benefit claim under 35 U.S.C. 386(c) to a prior-filed international design application designating the United States, the U.S. filing date of the international design application rather than the international filing date, if different, should be used.
