request to reinstate an application

If an application is abandoned due to a USPTO Office error, an applicant may file a request to reinstate the application, instead of a petition to revive. There is no fee for a request for reinstatement. You must file a request for reinstatement within two months of the issue date of the notice of abandonment. You must include a true copy of the document that was timely submitted, and a copy of an acceptable form of proof of receipt in the USPTO. — see TMEP §1712.01 for a list of evidence that may be considered in support of a request for reinstatement
