Abstract
By analyzing the granted patent distributions of key technical fields on the representative automobile firms Chery, BYD, Geely and Changan in China from 2008 to 2013, conclusions can be drawn as follows: In the hybrid power field, there is no big difference among the technological innovation achievements, and the overall granted patents are of high quality; In the blade electric vehicles field, there is a balanced development, and less the extreme phenomenon in the amount of granted patents, simultaneously it enjoys an obvious advantage; In the fuel cell vehicle field, the amount of granted patents is relatively low, and the extreme phenomenon and the unbalanced distribution of granted patents are obvious; In the battery technical field, the amount of granted patents is high, but still there exists significant gaps among the granted patent distributions of enterprises.
