What is the patent marking right?

According to the second paragraph of Article 17 of the Patent Law, the patentee has the right to indicate the patent mark on his patented product or the packaging of the product. As a selling point, patented technology is becoming more and more common in product advertising and product packaging. However, you can't just mark the patent. You should mark your own patents realistically, mainly in accordance with the Patent Marking Method. It should be noted that if the patentee exceeds the permitted scope, it may constitute a counterfeit patent.
