交易情景下专利价值影响因素分析

The influencing factors of patent value based on patent transaction

从专利交易情景的角度出发,分析专利价值的影响因素,对提升专利交易市场的效率和活性具有积极的现实意义。文章以2009-2016年江苏省技术交易合同整理获得的463份专利交易合同为基础,运用统计软件对手工搜集到的491条专利样本数据对专利价值的影响因素进行实证分析,结果表明,高校专利的价值显著低于企业专利的价值,且依据专利权人类型的不同,专利属性对专利价值的影响存在差异性。专利国际分类数和专利维持时间对高校专利价值具有显著正向影响,而企业专利价值受专利权利要求数的影响较为显著。此外,交易合同中的附条件支付条款可以显著增加高校专利的价值,但对企业专利价值的影响并不显著。

This paper studies the influencing factors of patent value from the perspective of patent transaction scenario which is of positive practical significance to improve the efficiency and energy of patent transaction market.This paper used the data of 463 patent transaction contracts(2009-2016)obtained from technology transfer contracts of Jiangsu province and it finally formed 491 patent sample.The research shows the value of university patent is obviously lower than that of enterprise patent in the current patent transaction market.Patent attributes have a particular influence on patent value under patent transactions,and it varies according to the patentee.The number of citations and patent maintenance time have a significant positive impact on the value of university patents.For corporate patents,the number of patent claims have a significant impact.The existence of pay-when-paid clause in patent transaction contracts could reduce the possibility of moral hazard and decentralize the development risk,so it can significantly increase the value of the patent of the university,but not significant for enterprise patents.
