Mobile phone box patent

Compulsory certification and patent certificate are not the same thing. If the box is marked as a patented product, the category and patent number of the patent must be marked: for example, China invention patent ZL * * * * * * * * * * If it is indeed a patented product, then the manufacturer should have a patent certificate. If you don't get a patent certificate, then writing a patented product on the box is a counterfeit patent.
