China's patent law stipulates that the patentee has the right to indicate the patent mark and patent number on his patented product or the packaging of the product. Patent mark refers to the mark that the patentee or patent licensee indicates on his patented product or package that he has obtained a patent in China within the patent validity period, such as "China patented product" or "counterfeiting of patented product will be investigated".
