You’ve likely seen the “TM” trademark symbol used in combination with various trademarks. The “TM” trademark symbol is widely utilized by individuals, businesses, and organizations to alert the public of their claim of ownership in a particular mark. Of course, using a “TM” doesn’t necessarily mean that the user of the mark actually owns any common law trademark rights or federal trademark rights whatsoever. For example, if I was to start selling soda under the name “COCA-COLA™,” I’d be a dirty little infringer since I clearly cannot obtain any trademark rights in the famous COCA-COLA name.
Once a trademark is registered with the United States Patent and Trademark Office (USPTO), the owner of the trademark may use the “®” registered trademark symbol in place of the “TM” in order to provide notice to the world that the trademark is federally registered.
