What is a “use-in-commerce” basis?

For applications filed under the use-in-commerce basis, you must be using the mark in the sale or transport of goods or the rendering of services in “interstate” commerce between more than one state or U.S. territory, or in commerce between the U.S. and another country. For goods, the mark must appear on the goods (e.g., tags or labels), the container for the goods, or displays associated with the goods. For services, the mark must be used in the sale or advertising of the services.
