Is there a patent for selling bags in Pinduoduo?

As an e-commerce platform, Pinduoduo will not sell patents, but commodities. The bags on Pinduoduo may come from different brands or manufacturers, and these brands or manufacturers may all have their own related patents. Therefore, when buying more bags, you need to pay attention to the origin and brand of the goods, and consider whether the purchased bags have copyright or patent conflicts with other brands. At the same time, as consumers, they also have the right to protect their own consumer rights. If you find similar problems, you can consult a professional lawyer.
