Enter the National Trademark Office website /sbcx/, click I accept, enter the query page, select trademark status query, enter the trademark application number to see the status of the trademark.

The Trademark Office receives about 2,000 trademark registration applications from all over the country every day. No one can guarantee that others have not submitted identical or similar trademarks before applying. Of course, the information being queried will have a time lag of about half a month.
