Legal analysis: Trademark objection defense is not a rejection review. Trademark objection defense refers to the legal act in which the opponent in a trademark opposition case files a written defense against the reasons for the objection within the statutory time limit. Rejection review means that the National Trademark Office rejects the applicant's registration application on the grounds that the trademark applied for registration violates the relevant provisions of the Trademark Law.

Legal basis: "Trademark Law of the People's Republic of China" Article 34 For a trademark that rejects the application and refuses to be announced, the Trademark Office shall notify the trademark registration applicant in writing. If the trademark registration applicant is dissatisfied, he may apply to the Trademark Review and Adjudication Board for review within fifteen days from the date of receipt of the notice. The Trademark Review and Adjudication Board shall make a decision within nine months from the date of receipt of the application and notify the applicant in writing. If there are special circumstances that require an extension, it can be extended for three months with the approval of the industrial and commercial administration department of the State Council. If the party concerned is dissatisfied with the decision of the Trademark Review and Adjudication Board, it may file a lawsuit with the People's Court within thirty days from the date of receipt of the notice.
