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.
