I have the idea of applying for a patent, but there are still too few people who know this knowledge. If we were more conscious, we would have many patents that would not be taken away by foreigners. When we use this technology again, we have to pay royalties to foreigners, which is very frustrating!
There are many rules in patent protection, which is very interesting. Used well, it is a powerful weapon. I don't understand, I can only be led by others.
