Only China applied for a patent and wanted to sell its products to the United States in the future. The United States did not apply for a patent. Can Americans make this product and sell it themselves? It can be counterfeited, which is why Huawei and others need to carry out patent layout and risk analysis before entering foreign markets. It's one thing to rush in and be counterfeited. If they have similar patents, they may be sued by the wicked first, saying that your products infringe their patents, and then they will pay their infringement fees.
