Junk patents have become a way to deceive laymen. Many fakes are marked with "national patent" and the patent number is given. The ones found are called "utility models" or "designs." These deliberately "ignored" contents are the key points and are deliberately hidden. As long as you consult knowledgeable people, you will know that these two types of patents can be authorized without substantive examination. Anyone can spend a few hundred yuan. They are both simpler than trademarks. A large number of primary school students have these two patents in their hands. These are what professionals call "junk patents." Deliberate confusion about the nature of patents is very common in current economic fraud cases. They are all using junk patents to conduct illegal activities in the name of "national patents". They have been exposed many times by the media. The typical ones are height-increasing products and myopia treatment devices. This trend should attract the attention of relevant departments.
