How to treat patents on the Internet?

First find the patent you need on HowNet, copy the patent number, and then paste the patent number on the national free patent website to find the patent you want and download it for free.

The same is true of foreign patents, but they are all in foreign languages! Downloading is also free.

This is determined by the characteristics of patents, protecting patentees and promoting human technological progress!

In particular, invention patents can be used free of charge after 20 years, and utility model patents can be used free of charge after 10 years.

I hope I can help you!
