First of all, the small handle contains many patents, and what you said belongs to the appearance patent. Not only with different letters or shapes, but also with different colors. Some games will use the characteristics of handles to design unique control methods. In the era when the game peripherals were dominated by the Japanese, Nintendo first used the letters AB. Everyone remembers that Contra started up, down, left and right in 3 lives, and then Z was used. Sega in Japan also slowly developed from A B to ABC, and then even went crazy to ABC XYZ and added LR. The reason why they were used came from the simplest idea. In the alphabet, ABC was the head and XYZ was the tail, so they didn't mean anything. In order to avoid patent disputes and be unique, Sony uses a square corner fork, which also has color characteristics. Sony was tortured by all kinds of patents at the earliest, and it often saved the life of soap. However, some of its own patents were established during its development, and a handle manufacturer in China also applied for a patent for key-press pictures.
then, it is legally unreasonable for ABXY to be used as a pattern patent, because it is the basic composition of characters, just like the reason that you can't apply for a trademark with the country name. Sega learned from Nintendo, and Microsoft learned from Sega to build XBOX, because Microsoft and Sega have always been good friends. Computer peripherals should be represented by 1234 numbers, because Microsoft is ambitious and wants to bring XB achievements to PC and become a rule maker. It has proved to be successful. This is good and bad for players. The advantage is that the game and the handle protocol are unified, and players can start the game without complicated settings. The disadvantage is that every time the factory produces an ABXY handle of Microsoft XI protocol, Microsoft takes away a lot of patent fees and increases the consumption burden of players.
please remember that each handle of Microsoft XI protocol has an independent ID number, so if you have five handles of the same type and plug them into the same USB interface of the computer in turn, you will find five new hardware and install five drivers, the traditional DX handle. No matter how many there are in the same model, you only need to find and install the driver once. In this way, Microsoft can accurately grasp how many ABXY handles of XI protocol have been produced on BlueStar, including itself and countless third parties, how many are in use, whether they are used on pc or XB, and how much share of the original ones are made by itself. Therefore, it is no problem for us to play games for entertainment, and we must know the truth of the matter, so as to establish a correct world outlook, clearly understand the nature of the enemy and firmly support our country. Try to make these damn things go to hell in the near future.
the size is not easy, please give points, thank you.
