What about trademark font infringement?

First of all, you need to read the contents of the infringement notice carefully to confirm the infringement and who the infringer is. If the infringement is really due to the use of unauthorized Hanyi fonts in trademarks, then you need to take measures to solve this problem as soon as possible.

Secondly, you can contact the design company, express your confusion and dissatisfaction to them, and ask them to bear corresponding responsibilities and compensation. If the design company refuses to take responsibility, it can consider seeking the help of legal institutions and seeking legal relief. If it is proved that the design company is indeed at fault, you have the right to ask them to bear corresponding responsibilities and compensation.

In addition, if unauthorized fonts are indeed used, they should be stopped as soon as possible to avoid further infringement. At the same time, you can also consider contacting Hanyi Font to discuss how to solve this problem, such as paying the corresponding licensing fee.

In short, in the face of infringement, you need to take it seriously and take active and effective measures to solve the problem. If you need legal help, you can seek the help of a professional lawyer.
