You can apply for a patent! But a friendly reminder, if you apply for this kind of patent, it will be difficult to find any market! Now it can be said that even manufacturers dare not change some computer standards at will, because this is "a matter that affects the whole body"! Who do you think would spend money to do a thankless task (it is easy to lose the market of the manufacturer by doing this kind of thing)?

The following are relevant materials:
Utility model patent: The total cost of applying for a patent by yourself is about 200 yuan or less, and hiring a patent office to represent you is about 1,000 yuan. Generally, it can be authorized in half a year to one year (utility model patents are protected by the state for 10 years and are easier to authorize, but the scope of protection is narrower than invention patents).
Invention patent: The total cost of applying by yourself is about 600 or less, or hiring a patent office to represent you is about 3,000 or less. Generally, it takes about 3 years to be authorized (invention patents are protected by the state for 20 years. There are no utility model patents that are easy to authorize, but the scope of protection is wider).
