First of all, in terms of patent fees, unlike MediaTek next door, their patent fees are charged according to the price of the whole machine. That is to say, if the price of your mobile phone is 1000 yuan, Qualcomm will charge 3% of the patent fee, but if you upgrade other mobile phone configurations, such as camera and screen, and the price is 2,000 yuan, I'm sorry, Qualcomm will still charge 3% of the patent fee.
Moreover, if you accept this, some mobile phone manufacturers will not say anything. After all, who let you have a chip? But the crux of the matter is that Qualcomm not only wants to collect overbearing patent fees, but also wants your patent in disguise. How do you say this? To put it bluntly, it is reverse authorization. Suppose you are a mobile phone manufacturer and buy a patent held by Qualcomm. According to the contract, your own patents should also be granted to Qualcomm.
To put it simply, to buy a bottle of Coke from Qualcomm, you should not only give people a certain patent fee, but also give your wife to Qualcomm to play with. In addition, Qualcomm can use your patent for free, and anyone who has bought his patent can use it. Besides, you can't make a deal with Qualcomm. What do you think mobile phone manufacturers will think?
On the other hand, other domestic mobile phone manufacturers are really sorry. Who told you not to develop your own chip, and the final result is people-oriented. However, the chip can't be made if you want to do it. Remember the fate of Xiaomi? I developed the pinecone chip, and as a result, I invested a lot of money, but I ended up on the street. Therefore, the threshold of chips can be much higher than that of mobile phones.
