摘要:本文选取申请年为2010年至2022年的专利,以智慧芽数据库为无效宣告数据来源,对其中被提起无效的专利进行统计分析。采用静态分析与动态分析相结合的方式,剖析中国专利文本质量的发展动态。本文从无效决定结果、IPC分类和无效宣告理由三个维度进行统计分析。静态分析是从全局角度披露中国专利文本质量状况;动态分析则是以时间为横坐标轴,细化分析专利撰写中的各类质量缺陷的发展动态。在无效宣告数据的基础上,探索数据背后的外部环境影响因素,帮助理清在现阶段有哪些是提升中国专利文本质量的关键环节。
This paper selects the patents applied from 2010 to 2022,and uses the Patsnap database as the data source to statistically analyze the patents that have been invalidated.The development trend of Chinese patent text quality is analyzed by combining static analysis with dynamic analysis.In this paper,statistical analysis is carried out from three dimensions,the invalidation decision results,the International Patent Classification(IPC)and the causes for invalidation.Static analysis discloses the quality of Chinese patent text from an overall situation perspective.Dynamic analysis is to analyze the development of various quality defects in patent texts over time.Based on the invalidation data,this article explores the external environmental factors,and helps to clarify the key issues to improve the quality of Chinese patent texts at this stage.
