Abstract: 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.
