Some intimate friends don't quite understand why many manufacturers choose Qualcomm instead of Samsung. Let me say it briefly. As we all know, in the field of electronic hardware, Qualcomm has the most patents in the world, none of them. Qualcomm holds a large number of patents in 3G and 4G communications, and its sales model is to bundle chips and patent licensing fees to earn a lot of profits. It can be said that Qualcomm is a company that makes profits by collecting patent fees! In addition, Qualcomm, which owns a large number of patents, has also implemented a strategy called "reverse patent licensing agreement". What does this agreement mean? Take Huawei as an example. We know that Huawei is also a company with a large number of patents, so Qualcomm held talks with Huawei. You hold my hand, I hold your hand, saying that we will not fight patent wars. My patent will be used for free, but equally, I can use your patent for free. ZTE, Huawei, Lenovo and other domestic enterprises all suffered big losses, so Qualcomm obtained a large number of patents for free use! In other words, if you use my Qualcomm chip, there will be no worries about patent issues! If you insist on using other chips, you have to pay me, or I will sue you for patent infringement! Basically, this patent fee can only be paid by local tyrants, such as Apple's Samsung manufacturers. Domestic manufacturers have thin profits and insufficient patent accumulation. Xiaomi is a typical example. They can't pay a large license fee to use other chips, and basically have no choice but to use Qualcomm's processors. Moreover, Qualcomm chips had a good reputation before 8 10, so domestic and foreign manufacturers took refuge under the umbrella of Qualcomm, so we can see that no matter which brand, high-end or low-end, Qualcomm Snapdragon chips were unified standard last year.
