Is it infringement that the patent involves counterfeit patent?

Patent imitation belongs to infringement. Patent right refers to the exclusive right granted to an invention-creation within a certain period of time after it has filed a patent application with the State Patent Office and passed the examination according to law. After the patent is granted, no one else may produce or sell the patented product without the permission of the patentee.
