So the PTO charges a processing fee of either $325 or $275 per trademark per class. What’s this “per trademark per class?”

Well, trademarks are classified in one of 45 international classifications. Sometimes, a product may be classified in more than one classification. For example, some products are classified differently depending on the type of material of which the product is composed. For example, plastic statuettes are in Class 20 while glass statuettes are in Class 21.

So, if you sell both plastic statuettes and glass statuettes under your trademark, then you may want to consider registering your trademark in both Class 20 and Class 21.

If you choose to do so, then the filing fee would be double for “one” trademark.

The more classes you file under, the more the processing fee will be. Take a look at the trademark for Dale Earnhardt Jr. They registered the trademark in 18 classes.
