I need to pay USPTO $100 because my Micro Entity Application was filled incorrectly. I plan to pay by check. From the website, I read the following:
Check or Money Order – make payable to "Director of the USPTO." There is a $50 processing fee for any check returned to the USPTO unpaid
I am not a regular check user. What does the "any check returned to USPTO unpaid" mean? how could that happen? If USPTO get the money, that extra $50 will not be charged. Am I right?
By the way, I will mail back with my corrected Micro Entity Application. I hope I will only be charged with that $30 surcharge fee.
