Therefore, in order to win a mobile phone patent war, the key point is patent. If the other party has a patent and you don't, you are sure to lose. If you have a patent right and the other party doesn't, you must win.
There are three ways to obtain a patent right:
The first is to apply for a patent by yourself, but it takes a long time to apply for patent authorization, and it will be too late to apply again when the war begins;
The second is to buy patents, and to buy other people's patents through patent transfer. This method is faster and more practical, but the transfer cost is higher, and sometimes the other party is not necessarily willing to sell the right patent.
The third is licensing, which is a mainstream way at present, and can obtain patent right quickly without paying high cost like patent transfer. For example, Qualcomm, a patent tycoon in the chip industry, cooperated with many mobile phone manufacturers such as Lenovo, ZTE, OPPO, Xiaomi and Samsung through patent authorization.
