Hello, my friend, it is not so difficult to apply for a patent for the catering industry. As long as you have your own new dishes in your store and they are not available anywhere else, you can apply for a patent if you meet certain application conditions. There are many benefits of patent application. For example, the 8th of Lu is the college entrance examination day. If your child had his own patent during school, there will be some extra points in the score of the college entrance examination. For example, there was a person who had a patent and betrayed the death penalty because he violated the law, but he had a patent, so he could get a reduction or exemption of the death penalty. Patents have different uses according to different industries. This is just my personal understanding, and it may not be comprehensive. I hope I can help your friend.
