It is because people don't understand the meaning of this patent number.
Patents are divided into invention patents, utility model patents and appearance patents.
For example, a small change in appearance can apply for a patent, so protection is actually the protection of product appearance. It does not explain the technology and treatment theory of the product itself.
Therefore, the patent number does not show the therapeutic effect of the product.
And the general public can't completely distinguish.
So, just ignore the patent description in product promotion!
