Patent holdup is a typical behavior of technical standards monopoly. It can be divided into different forms: cheating or refusing to disclose patent information before standardization, asking for licensing fee after standardization; against FRAND rules and asking for high licensing fee after standardization; abusing patent injunction. In US and EU,it was regulated under the frame of abusing the dominant position, and there is different testification standard of guilt ,also the reconciliation system is widely used in practice. For Chinese antitrust regulation on patent holdup, we should chose the low testification standard of guilty under the frame of abusing the dominant position, and give full play to the reconciliation system.
