At present, there is a phenomenon of patent squatting in society. What principle does it use to apply for a patent?

The principle of the first application is embodied in Article 9 of the Patent Law: "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 a patent for invention at the same time on the same day, and the patent for utility model obtained earlier has not been terminated, and the applicant abandons the patent for utility model, the patent for invention may be granted. If more than two applicants apply for a patent for the same invention-creation, the patent right shall be granted to the first applicant. " I hope my answer is helpful to you. Thank you.
