Can utility model patents include existing patents?

No, Article 9 of the Patent Law stipulates that "only one patent right can be granted for the same invention-creation. However, if the same applicant applies for a patent for utility model and an invention patent at the same time for the same invention and creation on the same day, and the previously obtained patent right for utility model has not been terminated, the applicant may grant the patent right for invention. "

In other words, you can apply for two first. When the utility model is authorized, the invention has not been approved. If your patent can be granted a patent right for invention, you must give up the previous patent right for utility model (of course, under the condition that the patent right for utility model has not been terminated) before you can be granted a patent right for invention, because the same invention (patent) can only be granted a patent right, which is the oneness in patent law.
