Wind Energy Patent Classification
Wind power is a one-subclass technology: F03D covers wind motors end to end, from rotor blades and pitch control to offshore foundations and wind-farm coordination.
That concentration makes F03D one of the cleanest subclasses for competitive analysis: the filing ranking below reads like the market ranking of turbine makers.
