The cost of registering a trademark in the United States can vary depending on the number of classes of goods or services and whether you file electronically or on paper.  A basic filing fee for an online trademark application with the USPTO costs from $250 per class of goods/services. This fee is non-refundable, even if your application is ultimately denied.    Additional fees allow you more time to show the mark’s use. Also, consider filing the Declaration of Use after 5-plus years; this can be around $225 and $525.
