The application date of a trademark refers to the date when the trademark application is submitted to the Trademark Office. This date is an important basis for judging whether registration can be approved. That is to say, if there is a trademark with the same name submitted to the trademark one day later than yours, Bureau, then the other trademark will be rejected; the registration date of the trademark is the date on the trademark certificate, that is, after review by the Trademark Office, if no reason for rejection is found, it will be announced, and no one files an objection after the three-month objection period. The date on which registration is approved. From this date, the ten-year validity period for trademark use begins. This is their difference.
