Legal analysis: Before a trademark is approved for registration, the applicant may apply to the Trademark Office for cancellation of registration.

There are two ways to cancel trademark registration:

1. Entrust a trademark agency registered in the Trademark Office.

2. The applicant shall go directly to the trademark registration hall of the Trademark Office.

Legal basis: Trademark Law of People's Republic of China (PRC).

Article 8 Any sign that can distinguish the commodities of natural persons, legal persons or other organizations from those of others, including words, figures, letters, numbers, three-dimensional signs, color combinations, sounds and combinations of the above elements, may apply for registration as a trademark.

Article 9 A trademark applied for registration shall have distinctive features and be easy to identify, and shall not conflict with the legal rights previously obtained by others.

Trademark registrants have the right to indicate "registered trademarks" or registration marks.
