Can an inadvertent omission in a reply lead to abandonment of a patent application?
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.
Not necessarily. Under 37 CFR 1.135(c), if a reply to a non-final Office action is a bona fide attempt to advance the application and is substantially complete but for an inadvertent omission, the examiner may give the applicant a new time period to supply the omission. The MPEP states:
“When a bona fide attempt to reply includes an inadvertent omission that precludes action on the merits of the application […], the examiner may consider that reply adequate to avoid abandonment under 35 U.S.C. 133 and 37 CFR 1.135, and give the applicant a shortened statutory time period of 2 months to correct the omission.”
This provision helps prevent abandonment due to minor oversights in otherwise substantive responses.
