What is the significance of Huawei charging Amazon patent fees?

The significance of Huawei charging Amazon patent fees is that it is a measure for Huawei to safeguard its own intellectual property rights. It is reported that Huawei has charged Apple a patent fee. It is reported that Apple paid Huawei a one-time patent fee of 600 million US dollars. Subsequently, Huawei asked American operator Verizon to pay the patent fee. Verizon initially disagreed. After Huawei sued Verizon, it is reported that Verizon finally paid a patent fee of $654.38 billion. Therefore, charging Amazon patent fees is also a way for Huawei to safeguard its intellectual property rights.
