First of all, there are three types of patents, utility model, design and invention patents.
The product you are talking about may belong to an invention patent or a utility model patent.
It is also very simple to distinguish the authenticity from the fake. You can check whether the patent application number or patent right number is given.
Then enter it through the China Patent-Property Query System. Number to check its status;
In addition, utility model patents are not valuable and it is easy to obtain patent rights; invention patents are valuable and difficult to obtain authorization;
However, for pharmaceuticals The fact that a product is patented only means that no one has done it before, but it does not mean how effective it is.
The products in the drug mainly depend on the approval announcement from the Food and Drug Administration.
Hope this helps.
