Legal analysis: 1. Applications for trademark revocation are charged according to category, and the trademark revocation fee for one category is RMB 1,000. If a trademark agency is entrusted to handle the matter, the Trademark Office will deduct the fee from the advance payment of the trademark agency. Therefore, in specific cases, the relevant parties need to collect fees reasonably based on the actual situation, but consultation is still required when handling the problem.

2. The conditions for trademark revocation must be met:

1. A registered trademark can only be revoked after it has been registered for more than 3 years. It should be noted that if a registered trademark has encountered opposition or objection review before being registered, the "three years" before it can be withdrawn shall be calculated from the date when the opposition ruling or opposition review ruling takes effect.

2. The application for "cancellation of non-use for three years" can be made for all the products approved for use of this registered trademark, or for one or several of the products approved for use of this trademark. If the "cancellation of non-use for three years" is for one or more items of a registered trademark, then the evidence of actual use provided by the registrant must be for that item or items, and evidence for other items will be invalid.

3. The registrant shall submit evidence of actual use of its registered trademark on schedule. After receiving the evidence materials, the Trademark Office will conduct evidence review and fact determination. If the review determines that the evidence can prove that the registered trademark has been actually used within the specified three-year period, a "decision letter that the trademark registration continues to be valid" will be issued. Otherwise, a "decision letter that cancels the trademark registration" will be issued. If the registrant and the applicant for cancellation are dissatisfied with the cancellation or maintenance decision made by the Trademark Office, they can submit a "cancellation review application" to the Trademark Review and Adjudication Board.

Legal basis: "Trademark Law of the People's Republic of China" Article 49 The trademark registrant, during the use of the registered trademark, may change the registered trademark, the registrant's name, address or other registration information on his own initiative If any matter is found, the local industrial and commercial administrative department shall order it to make corrections within a time limit; if it fails to make corrections within the time limit, the Trademark Office shall revoke its registered trademark. If a registered trademark becomes the common name of the goods approved for use or has not been used for three consecutive years without justifiable reasons, any unit or individual may apply to the Trademark Office to cancel the registered trademark. The Trademark Office shall make a decision within nine months from the date of receipt of the application. 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.
