A notice of abandonment is a written notification from the U.S. Patent and Trademark Office that an trademark application has been declared abandoned or, in other words, is no longer pending. If the application was abandoned unintentionally or due to Office error, the trademark applicant has a deadline of two months from the issue date of the notice of abandonment to file either (1) a petition to revive the application or (2) a request to reinstate the trademark application.
