Is it infringement to print back-to-back cases on slippers?
Infringement. According to the Trademark Law of People's Republic of China (PRC), it is an infringement of the exclusive right to use a registered trademark to use the same or similar trademark on the same or similar goods without the permission of the trademark registrant. In the case of producing slippers back to back, your behavior is an infringement and you should bear the corresponding legal responsibility. If you want to produce your own slippers for sale, you can register a trademark yourself, which will reduce many problems. If you want to fake it, I can only say that it is risky and you should be cautious in investing. I hope I can help you.
