The USPTO employs several hundred trademark examiners at any given time, although the number fluctuates with the strength of the economy, which influences how many new trademark filings are being submitted.[5] These employees are evaluated by a point system, based on the number of applications that they address and dispose of, either by permitting them to go forward to registration, or denying registration in an office action, and seeing this denial through any appeals taken within the USPTO. Some USPTO trademark examiners work in the USPTO building in Alexandria, Virginia, but a majority telework full-time.
