You can call the police if you are cheated by a patent agency, but I suggest you contact the local intellectual property office and other administrative departments. Local intellectual property offices will actively accept cases, on the one hand, investigate cases, and at the same time coordinate relevant law enforcement departments to transfer major cases to public security departments.
Patent literally refers to exclusive rights and interests. The word "patent" comes from Latin Litteraepatentes, which means open letters or open documents. It is a certificate used by medieval monarchs to issue certain privileges, and later refers to the exclusive rights certificate signed by the British king himself.
