How can I challenge a trademark application in the USA?

After a trademark application is reviewed, the US Patent and Trademark Office (USPTO) publishes it in the Official Gazette online. This starts a 30-day period for the public to oppose the trademark registration. If you have a personal or business interest and can show that the trademark will negatively impact you or infringe on your existing rights, you can stop the registration. This process helps ensure trademarks are genuine, unique, and reduce consumer confusion.

You can oppose a trademark application for reasons such as:

• The mark is generic and lacks distinctiveness.


• The mark is descriptive of physical features or geography, not unique.


• The mark raises social concerns.


• The mark is potentially misleading.


• The mark may dilute the uniqueness of an existing mark.

To oppose a trademark, file a Notice of Opposition with the USPTO, explaining why the mark should not be registered. The applicant then has 30 days to respond. The Trademark Trial and Appeal Board (TTAB) will set a date for the proceedings. Due to the complexity of trademark opposition, it's recommended to consult a trademark attorney to file the Notice of Opposition and handle the legal process.
