After the trademark registration passes the substantive examination, it will enter the preliminary approval and announcement process. The announcement period is three months. Within three months, anyone can object to the trademark. The opponent can file an objection at the end of the preliminary announcement. Submit an opposition application to the Trademark Office on one day (because the Trademark Office uses the postmark time when the opponent mails the opposition application as the opposition application date). If no one files an objection within three months, it will enter the registration announcement process, but sometimes the Trademark Office The trademark registration announcement time will be published in advance, so when you see the trademark registration announcement, it does not mean that the trademark has passed the preliminary approval announcement. The registration will be considered successful only on the last day of three months after the trademark preliminary approval announcement.
