How to judge whether a patent is practical?

Hello. Practicality means that the invention or utility model can be manufactured or used in industry and can produce positive effects. This means that this product can be made repeatedly, and it is useful to have positive effects. Generally speaking, in patent examination, whether it is practical or not is judged first, and then novelty and creativity are judged. If you still don't understand anything, you can ask them to consult Baidu Changsha Natural Selection. I applied for a patent there, and the service was very good and professional.
