When using patent survival evaluation index to represent patent quality, the index would ignore the updating circle difference among various technology area. Aiming at this defect, this paper summarizes broad research achievement, uses patent mechanism as theory guide, normalizes the patent survival time, and finally proposes a new patent quality index: patent dominance, which could replace the patent survival one. Besides, the paper discusses and proves the new evaluation index in both sector and overall dimension. The result shows, the new index overcomes the original evaluation indiscrimination in various technology area, effectively solves the problem of patent quality cooperation in different areas, and could improve the patent evaluation effect.
