MPEP 714.17: Amendment Filed After the Period for Reply Has Expired
This is the Ninth Edition of the MPEP, published in March 2014
When an application is not prosecuted within the period set for reply and thereafter an amendment is filed without a petition for extension of time and fee pursuant to 37 CFR 1.136(a), such amendment shall be placed in the file of the application, but not formally entered. The technical support staff shall immediately notify the applicant, by telephone and letter, that the amendment was not filed within the time period and therefore cannot be entered and that the application is abandoned unless a petition for extension of time and the appropriate fee are timely filed. See MPEP § 711.02.
