What is a ‘bypass’ application in patent law?
This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.
A ‘bypass’ application refers to a continuation, divisional, or continuation-in-part of an international (PCT) application filed under 35 U.S.C. 111(a) instead of entering the national stage under 35 U.S.C. 371. As stated in MPEP 211.01(c):
Rather than submitting a national stage application under 35 U.S.C. 371, applicant may file a continuation, divisional, or continuation-in-part of an international (PCT) application under 35 U.S.C. 111(a). Such applications are often referred to as ‘bypass’ applications.
This option allows applicants to claim the benefit of an international application’s filing date while following the procedures for regular national applications.
