The law once said that to file an application for a United States federal trademark registration, an individual or a business had to actually be using the mark in interstate commerce. That individual or business must have actually sold the goods or services to someone in another state, or their sale of the goods or services had to have had an effect on interstate commerce. There was no way to “reserve” a name prior to actual usage.
In 1989, however, the Trademark Act was amended to allow for an “intent to use” application (ITU) to be filed with the United States Patent and Trademark Office (USPTO). While actual use in interstate commerce is required to issue a registration, the ITU application allows an individual or business with the bona fide, good faith intent to use a certain mark to file an application in advance with the USPTO.
