Why is a registered trademark important?
A trademark protects a brand to ensure that others are not infringing the mark or diluting its strength. If someone else uses the same or substantially similar trademark to identify the same or similar goods or services, the trademark owner can start a proceeding before the United States Trademark Trial and Appeal Board (TTAB) to cancel or oppose the registration of the infringing mark, or file a trademark infringement claim in court to stop the use of the mark and recover damages (money).
With a registered trademark, you can use the ®, letting the world know your mark is protected. Having a registered trademark adds prestige, legitimacy, and value to your brand. A registered trademark also entitles the owner to enhanced damages in case of infringement.
