专利家族规模对专利价值贡献变化研究——以太阳能领域为例

Research on the Contribution of the Number of Patent Families to the Value of Patents——Taking Solar Energy as an Example

[目的 /意义]旨在明确专利家族规模改变对专利价值贡献的变化情况,同时为专利战略布局优化和专利价值评估提供重要参考。[方法 /过程]以新型清洁能源太阳能领域为例,识别高价值和低价值专利数据集,针对高低价值专利之间专利家族规模差异设计实验,利用SPSS 22进行验证。[结果 /结论 ]专利家族规模对专利价值贡献并非一成不变,随着专利家族规模的不断扩大,专利家族数量占比在高低价值专利之间的差异性不再显著,此时专利家族规模增加对专利价值的贡献明显减小。

[Purpose/significance]Research on the contribution of the number of patent families to the value of patents can provide an important reference for patents strategy layout optimization and patent value evaluation.[Methods/process]Taking the new clean solar energy field as an example,we identified high-value and low-value patent data sets,and designed experiments on patent family size differences between high-value patents and low-value patents.Finally,then SPSS 22 was used to verify the model.[Results/conclusion]Empirical research have shown that the contribution of the number of patent families to the value of patents is not invariable.With the continuous expansion of the patent families,the proportion of patent families is no longer significant difference between high-value patents and low-value patents.At this time,the increase in the number of patent families has significantly reduced the contribution to patent value.
