Is the appearance of Hermes horseshoe bag infringing?

No infringement. Unauthorized use of the appearance of other people's products without the consent of the patentee may constitute infringement. Effective patent means that the design patent pays the annual fee on time within the validity period. It is illegal to copy the external packaging of other products, and the infringer should bear the corresponding civil liability. Therefore, the appearance of Hermes horseshoe-shaped bag is not infringing, because Hermes bag is a horseshoe-shaped printed gold buckle, which is a unique symbol of Hermes.
