It helps to understand the legal concepts of trademark and copyright law so that your band name and materials are protected from being used without your permission. Copyright and trademark laws are two forms of intellectual property rights that allow owners, inventors, and creators to protect their works from unauthorized use.
Trademarks protect distinctive brand signifiers, such as words, names, symbols, sounds, and colors used in commerce to distinguish products and services by their company or brand.
Copyrights protect specific creative works, such as a song or painting.
Especially if your band has promotional artwork, you should be aware of how these protections work so you can guard your creations with a copyright.
