Is the design prototype infringing?
there will be infringement, and the defendant is at great risk. Whether it is infringement or not, you should compare the alleged infringing products you sell with the plaintiff's copyright registration pictures. If they are substantially similar, it will constitute infringement. But if you can provide the legal source of the product, you don't have to bear the tort liability. According to the Trademark Law, there is an entrustment relationship between the designer and the trademark owner.
