Reasonable practice, according to the type of invention and market demand, whether to apply for a patent. If the demand is small, keep it for the time being. Only when the demand is considered, the patent can be transformed into a commodity, and the benefits can be realized. You have to find a partner or a processing enterprise to produce it yourself.
Keeping business secrets means that if this patent is made public and developed too early, people can't accept it, or can't afford it, or the concept can't accept it. Keep it a secret for the time being! ! !
