摘　　要：本研究应用直接法(寿命表法)和失效专利维持年限统计法对上海市2001年至2020年的全部发明专利授权数据进行分析,分别计算出了发明专利平均预期寿命和失效发明专利平均维持年限,通过对比表明,发明专利平均预期寿命与失效发明专利平均维持年限总体上正相关且明显高于后者,上海市发明专利自申请日起计算的平均预期寿命已经达到9.12年。同时,上海各区之间发明专利平均预期寿命差异很大,应当采取针对措施提升专利平均预期寿命。专利平均预期寿命指标兼顾了失效专利与存量专利的数量与维持时间长度等因素,可以客观全面反映专利的整体现状,应该成为衡量专利质量的重要指标。In this study,the direct method(life table method)and the statistical method of maintenance years of invalid patents are used to analyze the authorization data of all invention patents in Shanghai from 2001 to 2020.The average life expectancy of invention patents and the average maintenance life of invalid invention patents are calculated respectively.The comparison shows that,the average life expectancy of invention patents is positively correlated with the average maintenance life of invalid invention patents,and is significantly higher than the latter,and the average life expectancy of invention patents in Shanghai from the date of application has reached 9.12 years.At the same time,the average life expectancy of invention patents varies greatly among Shanghai districts.Targeted measures should be taken to improve the average life expectancy of patents.The average life expectancy index of patents takes into account factors such as the number and duration of invalid patents and existing patents.It can objectively and comprehensively reflect the overall status of patents.It should become an important index to measure the quality of patents.
