Leave blank if there are no words in your trademark (i.e. you registered a logo/design with no words in it).
If you want to sell multiple trademark registrations that are related to each other (e.g. name and logo), list all registration or serial numbers of the trademark registrations you want to sell, separated by spaces or commas.
Where are you using the trademark in commerce, if anywhere? This can be a standalone website or a listing on a website like Amazon or Yelp.
Write any additional notes you might have for us.
