We do an Extensive Federal, State, and Common Law Trademark search for your proposed trademark to ensure that your trademark is available and will not infringe on any other registered or unregistered trademark.*Please note that while we can begin the comprehensive search to clear your mark, your trademark will be filed once you make your final payment. In-house payment plans shall only be used if you were denied for Sezzle’s payment plan option, and you absolutely need assistance with the cost of protecting your brand.
