What steps should I take if I receive a notice that someone is opposing my trademark application?

If you receive a trademark notice of opposition, it indicates that someone is challenging your trademark application, claiming it should not be registered. This opposition is filed with the Trademark Office, often because the opposing party believes your trademark infringes on theirs.

Receiving a notice of opposition doesn't mean you've lost your trademark, but you must defend it to proceed with registration. It's advisable to hire a professional trademark service like Protect.TM or a trademark attorney who knows the laws in your area. Your legal representative must submit your defense within the timeframe set by the Trademark Office.
