What's the use of buying patents? For example, recently Apple bought Huawei's patent, which means that Apple developed the same technology, but Huawei developed it first, so it is necessary to buy it.

First of all, we need to see what kind of apples belong to. Apple is not a technology development company. Is a design company without research and development capabilities. Although there is a 12CPU, it is based on the framework kernel of arm. Not to mention that Apple has money, it is a software-based enterprise like Xiaomi. It can also produce high-performance CPU, PengS2, because of the special core technology of ARM. It is natural that you pay me with your skills. On the other hand, why does Apple use the communication technology of Huawei and Qualcomm? Because these two companies are communication technology solution research and development companies, which belong to first-class standard-setting companies, while Apple is only a design company, which belongs to a third-class enterprise, and Samsung has a gorgeous screen. Huawei and Qualcomm have more than 20 years of communication technology, which is quite mature. Even the best Intel chip manufacturing company will take five years to develop baseband, and the signal is still unstable. There are only 4g standards, and it takes a lot of time to develop 5g without knowing how to design the framework. For a design company, it takes time, energy and money to develop it by itself. After successful research and development, people can't keep up with the era of 10G, so we have ready-made technology to develop it ourselves, and Apple has to adopt Intel's baseband chip. In the future, Apple will not only have poor communication signal, but also will not adopt Qualcomm and Huawei, so it will not be able to produce a 5G mobile phone in the last three or four years. This is why Apple stole other people's technology and didn't want to pay the patent fee, so it was sent to the Supreme People's Court.
