Legal analysis: Trademark objection review is written review, so evidential materials are the key to success. If the parties insist on asking the success rate, they can only say that the overall success rate of trademark objection is less than 5%. However, this data is not enough to evaluate whether a specific objection case can be successful. Because the specific circumstances of any trademark objection case are very different, the use of trademarks is different.

Legal basis: Article 49 of the Trademark Law of the People's Republic of China * * * If a trademark registrant changes the registered trademark, the name, address or other registered items of the registrant during the use of the 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. If a registered trademark becomes the common name of the goods it has approved for use or is not used for three consecutive years without justifiable reasons, any unit or individual may apply to the Trademark Office for cancellation of the registered trademark. 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.
