In the eyes of ordinary people, patents are very powerful. I don't know that patents are divided into three or six categories, let alone utility model and design patents. Authorization does not need to go through substantive examination, that is, you can get a patent certificate by paying money. But what can we do? Someone is suing others for utility models and designs, and the court wants them to go to the patent office to reissue the report. What's the use?
But lying to laymen is useful, and many scammers can take advantage of it. Just like many scammers used a celebrity dictionary to prove that they were celebrities, just for money. Now it is out of date, and junk patent is a new form of deception. Cheating laymen with junk patents, Taobao and TV shopping are the most popular. Formal institutions are embarrassed to take out utility model and design patents for fear of making people laugh.
A patent that has undergone substantive examination is an invention patent. After four or five years of substantive examination, very few patents were granted. That's real technology. Litigation is hard goods, and there are invention patents that professors can use. You can ask these junk patents of utility model design, but what else can you do?
After substantive examination, the category code of invention patent is 1, and the code of utility model and design is 2 or 3. There are many junk patents, and the significance of patent number is very important. Don't think that patents are all the same, even certificates are different in color. Be careful of being cheated by junk patents. Cheating people with junk patents is very popular on Taobao.
