Legal analysis: If a registered high-quality trademark is not used for three consecutive years, it is likely that someone else will apply for cancellation and re-registration.

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.
