摘要

随着科技的发展,专利篇幅和专利保护权项数量呈现逐渐增多的趋势。但是,这两个专利长度指标与专利质量之间的必然关系却没有得到充分研究。通过对这两个专利长度指标的整体态势、时间趋势、国家分布、机构合作和引证等的分析与对比,发现专利篇幅虽然呈逐渐增加的趋势,但目前最受关注的仍是短篇幅的专利;而专利保护权项数量与专利引证次数之间存在着线性增长相关。因此,认为专利保护权项数量可以作为专利质量评价的有效指标之一。

Abstract

With the development of technology, the patent length and the number of patent protection items have increased gradually. However, the necessary relationship between the two patent length indexes and patent quality has not been fully studied. This paper analyzes and compares the overall situation, time trend, countries distribution, institution cooperation and patent citation of two indexes. It finds that the short patents are the most concerned while the patent length is increasing step by step, and there is linear growth relationship between the number of patent protection items and patent cited times. Therefore, the number of patent protection items can be used as one of valid indexes of patent quality evaluation.

Key words： patent length; number of patent protection items; patent index; patent citation
