Legal analysis: after an enterprise applies for a trademark, it cannot use the trademark at will. The nonstandard use of a trademark means that the actual use mark of the trademark is inconsistent with the mark on the registration certificate. These inconsistencies include inconsistent colors, inconsistent fonts and other acts of changing the logo of registered trademarks without authorization. Non-standard use of trademarks can be registered, and trademarks can be revoked by administrative organs according to law. Where a registered trademark is changed by itself and stopped being used for three consecutive years, the Trademark Office shall order the trademark registrant to correct or cancel its registered trademark within a time limit. Trademark registrants do not regulate the use of registered trademarks. In the course of civil litigation, the defendant often argues that the trademark registrant has applied to the Trademark Office for cancellation after not using the registered trademark for three years. At the same time, in the process of civil litigation, the people's court's determination that the trademark registrant has not actually used the registered trademark will also be used by other interested parties as the basis for applying to the Trademark Office for cancellation of the registered trademark.

Legal basis: Article 49 of the Trademark Law of People's Republic of China (PRC). Where a trademark registrant changes its registered trademark, name, address or other registered items on its own during the use of a registered trademark, the local administrative department for industry and commerce shall order it to make corrections within a time limit. If it fails to make corrections within the time limit, its registered trademark shall be revoked by the Trademark Office. Any unit or individual may apply to the Trademark Office for the cancellation of a registered trademark if it becomes the common name of a commodity approved for use or if it is not used for three consecutive years without justifiable reasons. The Trademark Office shall make a decision within nine months from the date of receiving the application. There are special circumstances that need to be extended, which can be extended for three months with the approval of the administrative department for industry and commerce of the State Council.
