Is the sale of patented products effective?

Article 11 of the Patent Law stipulates: "After the patent right for invention and utility model is granted, no unit or individual may exploit its patent without the permission of the patentee, that is, it may not manufacture, use, promise to sell, sell or import its patented products for production and business purposes, or use its patented methods and use, promise to sell, sell or import products directly obtained according to the patented methods." Therefore, according to the current patent law, the expression of intention to sell patented products for the purpose of production and operation is also prohibited by law.
