(1) According to the provisions of Article 27, Paragraph 1, of the "Regulations on the Implementation of the Trademark Law of the People's Republic of China", the Trademark Office shall promptly send a copy of the trademark objection material to the party being opposed, The party is limited to respond within 30 days from the date of receipt of a copy of the trademark opposition materials. If the objected party fails to respond, it will not affect the decision of the Trademark Office.

Therefore, judging from the cases served by Baiqi Intellectual Property Agency, it seems that after receiving the objection defense notice, you can indeed choose not to respond. However, this is undoubtedly tantamount to losing the right to express one's own opinions. The entire case will lack a statement belonging to one's own side, thus making it impossible for the Trademark Office to learn about the situation of the opposed party, and the decision made may be unfavorable to the opposed party.

(2) If you miss the defense deadline, you can first wait for the Trademark Office to issue a decision on the objection. If the Trademark Office makes a decision not to register, then according to the provisions of Article 35, paragraph 3, of the Trademark Law of the People's Republic of China, the Trademark Office makes a decision not to register, and the opponent If you are dissatisfied, you may apply to the Trademark Review and Adjudication Board for review within fifteen days from the date of receipt of the notice.
