Changing the font of a trademark is an act of counterfeiting a registered trademark, which is easy to cause disputes and is not conducive to the protection of trademark rights. It is suggested to apply for registration of the changed new trademark.

Article 24 of the Trademark Law stipulates that if a registered trademark needs to change its logo, it shall re-apply for registration. Article 49 stipulates that if a trademark registrant changes the registered trademark, the registrant's name, address or other registered items by himself in the process of using 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.

This means that the use of trademarks should be strictly limited to approved registered trademark patterns and approved goods. If the trademark pattern is changed or used beyond the approved scope of goods and across categories, the registered trademark shall not be marked, otherwise it is an act of counterfeiting the registered trademark; If the altered trademark pattern or the goods beyond the approved scope of use are the same as or similar to the registered trademarks of others, they shall also bear the legal liability for trademark infringement.
