Legal analysis: Generally, the success rate of a trademark after the preliminary announcement is relatively high. However, it should be noted that the trademark announced by preliminary examination and approval is not equal to approval and registration, that is to say, the trademark applicant has not yet obtained the exclusive right to use the trademark, and the trademark will be approved and registered only if no one makes a proposal or the proposal is ruled invalid during the announcement period and the trademark office publishes a registration announcement.

Legal basis: Article 33 of the Trademark Law of the People's Republic of China, if, within three months from the date of announcement, the prior obligee or interested party thinks that the trademark announced after preliminary examination and approval violates the provisions of Article 13, paragraphs 2 and 3, Article 15, Article 16, paragraph 1, Article 3, Article 31 and Article 32 of this law, or anyone thinks that it violates Article 4 and Article 32 of this law. If there is no objection at the expiration of the announcement period, the registration shall be approved, a trademark registration certificate shall be issued and an announcement shall be made.
