Construction and Empirical Research on the Pre-application Value Assessment System of Patent in Universities
Patent value assessment before patent application in universities can promote the transformation of scientific and technological achievements of universities by screening high-value patents and strengthening the management and support for the protection of high-value patents.Chinese universities are actively exploring and implementing the guidelines for pre-application evaluation,but a more unified evaluation mechanism has not yet been established in China.Therefore,from the strategic perspective of cultivating high-value patents in Chinese universities,based on the integration of literature combing and combining the patent pre-evaluation mechanisms of Stanford University,Beijing Jiaotong University,Xi'an Jiaotong University,and other domestic and foreign universities,this paper uses the entropy power method to construct a pre-patent application value evaluation index system for universities that contains five value dimensions and 17 indicators,including technological,legal,market,strategic,and economic dimensions,taking 3 452 public patents applied by Beijing Jiaotong University from 2017 to 2021 as samples,conducts multi-dimensional comprehensive evaluation on some patents with high value scores by using BP neural network and hierarchical clustering method.The results find that:in the patent value pre-assessment model,the economic value and technical value are the more important two dimensions,while the patent license and transfer negotiation,patent implementation,and the degree of market support are the important indexes;the patents of the sample universities have certain differences in technical novelty,legal protection,strategic portfolio,market potential,and transformation ability,and the gap between the patent value scores is large,the simulation value obtained from BP neural network model fits 99.95%with the actual value;the evaluation model can effectively identify the high-value patents within the universities,and the evaluation system is operable and scientific.Accordingly,universities should accurately locate the global disciplinary frontiers and market demands,and improve the patent value by increasing the number of patent embodiments,citing high-quality literature,and expanding the technological breadth and other perspectives.
