What is reverse counterfeiting patent infringement?

Reverse counterfeit patent infringement: this kind of infringement mainly refers to the actor legally obtaining other people's patented products, and then marking his own patent number and selling them. Although this kind of behavior is not enough to constitute the act of "counterfeiting others' patents", in fact, this kind of behavior violates the marking right of the legitimate patentee, which is more serious than counterfeiting others' patents, and such infringers should bear civil liability.
