NOA - a written notification from the USPTO that a specific mark has survived the opposition period following publication in the Official Gazette, and has consequently been allowed for registration. It does not mean that the mark has registered yet. Receiving a notice of allowance is another step on the way to registration.

Notices of allowance are only issued for applications that have been filed based on "intent to use". The notice of allowance is important because the issue date of the Notice of Allowance establishes the due date for filing a statement of use. After receiving the Notice of Allowance, the applicant must file a statement of use or a request for an extension of time to file a statement of use within 6 months from the issue date of the notice. If the applicant fails to timely file a statement of use or a request for an extension of time to file a statement of use, the application will be abandoned.
