Patent hooligans' manipulation of patents belongs to a market behavior, and the government should not interfere too much. However, just like any commercial operation, when it has an adverse impact on the overall social welfare or public interests, the government has the responsibility to intervene, especially when the object of "patent hooligans" is the patent right, and the patent right is authorized by the government, so the government's supervision becomes more important. In fact, the government's concern and intervention on "patent hooligans" not only occurred in the United States, but also existed in Europe. For example, there are many anti-monopoly or unfair competition lawsuits involving patent hooligans in the European Union (for example, the German patent hooligan company Nokia v. IPCom, and the Canadian patent hooligan company Google v. Nokia, Microsoft and Masaid). However, it should be noted that government supervision needs to grasp two important aspects: timing and degree, when and where intervention is needed, how to intervene, and to what extent. Otherwise, government behavior will disrupt normal market behavior, which may not only be detrimental to the development of society, economy and technology, but also be counterproductive.
