Import products that have not been patented abroad but have been patented in China.

It must be against the rules. Article 11 of China's Patent Law stipulates that after the patent right for invention and utility model is granted, no unit or individual may exploit the patent without the permission of the patentee, that is, it shall not manufacture, use, promise to sell, sell or import its patented products for production and operation purposes, nor shall it use its patented methods and use, promise to sell, sell or import products directly obtained according to the patented methods.

After the design patent is granted, no unit or individual may exploit its patent without the permission of the patentee, that is, it may not manufacture, promise to sell, sell or import its patented product for production and business purposes.

Patents are regional. The patent applied by China only enjoys the patent right in China, and so does the United States. Unless the same patent is filed in China, the international application is filed in the United States. With the permission of the patentee, the import and export between the two countries will not be infringed.
