Licensing thus soon proved to be insufficient, particularly given the ambitions of the Chinese wind energy programme, which aimed largely at the commissioning of large-scale wind farms employing megawatt turbines (1.5 MW and higher). The focus shifted away from licensing to the commissioning of "original constructions” delivered by international design and consulting firms. This has had two advantages: first, the cost of design tends to be substantially lower than licensing fees (one third, according to one Chinese expert), second, in general, once the design firm has delivered the blueprint, the Chinese client owns the intellectual property rights to the design.
