Trademarks identify the source of goods or services. They can be registered with trademark offices such as the USPTO to get protection. Once registered, the brand can display them as it chooses. For example, the NIKE name trademark can be placed on a shoe, packaging, ad, or website. Domain names are different. They are part of a web address that links to a website. For example, in the website http://nike.com, the domain name nike.com is registered in a domain name registrar, which does not grant trademark rights.
