The Best Trademarking of a band name
Music recordings are products, and entertainment is a service, so a name used to identify the source of a song or the musicians who performed it is a trademark.
Trademark rights are created by using a name or symbol associated with the product or service to identify the source of the product or service.
Trademark rights come into existence when a band takes action to name a product (such as a CD, or digital recording available for download on the Internet) or advertises the product, or publicly performs or advertises entertainment services in the name.
