Patent search can be searched directly on the Internet, and patents have public description materials. Otherwise, how can others know whether there is infringement?
I remind you that it costs money to apply for a patent, and it also costs money to maintain a patent.
if you really want to apply, I suggest you find an agent to do it, search online, find several patent agencies in your city, call and ask, and I will usually tell you more details. Although it costs more to find an agent, it should be worth it, especially if it has never been done before.
In addition, invention patents are relatively difficult. The utility model is very simple, basically willing to spend money, and agents can help you apply for it.
