Abstract: Using maintenance time as indicator, this paper concludes that the wind-power technology invention patents have a low quality compared with foreign invention patents after the evolution tendency of wind-power technology in China is analyzed. Taking the invalid invention patents from the year of 1985 to 2013 as a research subject and using Multiple Linear Regression Model, the author finds that, the most influential factor is the patent annual fee among the six independent variables, followed by the number of patent family, the number of inventors, researchinstitute or individual and the time of patent review in turn. Then, based on the results of the model, the author puts forward some countermeasures and suggestions to improve the quality of wind-power technology invention patents in China.

Key words: wind-power technology, patent quality, maintenance time, influencing factors
