摘　　要：提出核心专利综合价值指数(CICP)的概念,并采用粗糙集理论方法确定了CICP指标权重系数,在构建核心专利综合评价指标的基础上,通过计算CICP值识别核心专利,最后从风能领域1 802件专利中识别出了10件核心专利,识别结果较为准确。The paper builds the core patent comprehensive evaluation index system, and identifies the core patents by the use of core patent comprehensive value index （CICP）. the index weight is measured by Rough Set,identifying 10 core patents of 1802 results in wind power area at last, and this result of identification is accurate.

关 键 词：核心专利 专利指标 粗糙集
