in principle, trademark registration should be based on the principle of on-demand application, that is, applying for registration of the trademark actually used in actual business. The specific measures to prevent withdrawal are:

1. Collect the evidence and materials used. Such as product packaging, trading documents, magazines and newspapers, exhibition activities, etc.

2. Give reasons for not using it properly. Article 67 of the Regulations on the Implementation of the Trademark Law stipulates that a registered trademark that has not been used for three consecutive years due to force majeure, government policy restrictions, bankruptcy liquidation and other reasons is "justified" and will not be revoked. If a registered trademark of a drug has not been used for three consecutive years due to the approval of drug listing, it is "justified" and will not be revoked because of the "withdrawal of three" clauses.
