If you do not have proof now, you can submit proof later after your trademark is submitted to the Trademark office. If you do it later, you will need to
pay a $100 government fee (for US trademarks).
Later in this process, Brand Mark Protect collects and pays the government-discounted TEAS Standard electronic filing fee of $350. In some circumstances, your application may qualify for the less-available
TEAS PLUS system which means we will pay $250 to the USPTO which streamlines the process. If your application qualifies for TEAS PLUS, we will use it and retain the difference between the TEAS Standard
filing fee and the TEAS Plus filing fee as a result of the additional processing by the Brand Mark Protect.
