How are continuation-in-part (CIP) applications filed under former 37 CFR 1.62 treated?
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.
Continuation-in-part (CIP) applications filed under former 37 CFR 1.62 on or after December 1, 1997, are treated as improper applications, regardless of the original application’s filing date.
The MPEP specifically states: A request filed on or after December 1, 1997, under former 37 CFR 1.62 for a continuation-in-part (CIP) application, or for a continuation or divisional of an application having a filing date before June 8, 1995, will be treated as an improper application.
This means that applicants seeking to file a CIP application after December 1, 1997, would need to use a different filing procedure, such as filing a new application under 37 CFR 1.53(b).
