The first patent is not classified by name, and there is no such general concept as "wind power generation" patent;
There will only be patents related to wind power generation,
Even related patents cannot be classified as "wind power patents"
For example, the product patent of wind turbine, the use method patent, the control system patent, the power generation forecasting method patent, and the wind farm location patent. . . .
Every country has something related to it in every era, and the whole world can't say anything. . .
