To some extent, it depends on what kind of lawyers Huawei intends to hire in the United States, and that's all Huawei can do. However, there is another possibility, that is, the U.S. government is involved. However, the U.S. government has been criticizing China for not respecting intellectual property rights, so publicly supporting Verizon to refuse to pay by administrative order will not have any impact. This is not only Huawei's problem, but will first involve the national level, which will cause great damage to the global intellectual property pattern. I believe it will not be done easily.
The United States should not refuse to pay, because if it refuses, it will not recognize patent protection and protect intellectual property rights. In this case. Companies in other countries should worry that the United States will do the same thing to itself. The United States has to worry that China will do the same. After all, the United States will suffer from fraud in intellectual property rights.
