37 CFR 1.135(a) specifies that an application becomes abandoned if applicant “fails to reply” to an office action within the fixed statutory period. This failure may result either from (A) failure to reply within the statutory period, or (B) insufficiency of reply, i.e., failure to file a “complete and proper reply, as the condition of the case may require” within the statutory period (37 CFR 1.135(b)).
When an amendment is filed after the expiration of the statutory period, the application is abandoned and the remedy is to petition to revive it. The examiner should notify the applicant or attorney at once that the application has been abandoned by using Notice of Abandonment form PTOL-1432. The proper boxes on the form should be checked and the blanks for the dates of the proposed amendment and the Office action completed. The late amendment is placed in the file wrapper but not formally entered. See MPEP § 714.17.

A petition to revive may be appropriate if applicant’s failure to reply was unintentional, as set forth below.
Failure to reply was unintentional.
A petition to revive an abandoned application on the grounds that the failure to reply was unintentional (37 CFR 1.137) must be accompanied by: (1) the required reply (which has been filed); (2) a statement that the entire delay in filing the required reply from the due date for the reply until the filing of a grantable petition pursuant to 37 CFR 1.137 was unintentional; (3) any terminal disclaimer required pursuant to 37 CFR 1.137(d); and (4) the $ petition fee as set forth in 37 CFR 1.17(m). No consideration to the substance of a petition will be given until this fee is received. The Director may require additional information where there is a question whether the delay was unintentional.
The required items and fees must be submitted promptly under a cover letter entitled “Petition to Revive.”
