If there is a prior right, it is infringement, if not, it is not infringement, which can be divided into several situations:
1, peripheral products with celebrity portraits definitely infringe on the celebrity's portrait rights.
There is no portrait of the star, but it is a product designed by the star himself. For example, a star drew an anime image and made it around, infringing the copyright of this work.
There is no portrait of the star, and it is not designed by the star himself. It's just a product that stars use or love in a film and television drama. If the product has no patent right for design and does not involve copyright (conventional dolls, such as bears and rabbits, or conventional items, such as key chains), there is no infringement.
