Legal analysis: Font is an important component of text signs. If a trademark has been registered and used, others have also registered. Although the font is traditional, it still constitutes infringement. For trademark infringers, the parties concerned may require them to stop their acts and compensate for the losses. Anyone who infringes on the exclusive right to use a registered trademark may complain or report to the administrative department for industry and commerce at or above the county level where the infringer is located or where the infringement occurs.

Legal basis: Article 57 of the Trademark Law of People's Republic of China (PRC) commits any of the following acts, all of which are violations of the exclusive right to use a registered trademark:

(1) Using the same trademark as its registered trademark on the same commodity without the permission of the trademark registrant;

(2) Without the permission of the trademark registrant, using a trademark similar to its registered trademark on the same kind of goods, or using a trademark identical with or similar to its registered trademark on similar goods is likely to cause confusion;

(3) selling goods that infringe upon the exclusive right to use a registered trademark;

(4) Forging or unauthorized manufacturing of registered trademark marks of others or selling forged or unauthorized registered trademark marks;

(five) without the consent of the trademark registrant, the registered trademark is changed and the goods with the changed trademark are put on the market again;

(6) Deliberately facilitating the infringement of the exclusive right to use a trademark of others and helping others to commit the infringement of the exclusive right to use a trademark;

(seven) causing other damage to the exclusive right to use a registered trademark of others.
