Abstract

[Purpose/significance] This paper summarizes the latest progress in the research and practice of patent value evaluation indicators, comments on its research and improvement ideas, and looks forward to its future.[Method/Process] This paper systematically sorted out the commonly used patent value evaluation indicators in patent information research and service work, extracted five indicators that were typical of improvement ideas, including Patentics creation potential, patent significance indicator, PatentSight patent asset index, Patentics patent quality, and literature disruption index, and sorted out the progress. Then it reviewed and prospected the improvement ideas of these indicators.[Result/Conclusion] Patent value evaluation indicators based on objective data are the current research trend of patent value evaluation. Typical ideas for improving indicators include four types:based on semantic relevance before and after patent application, based on big data to modify classic evaluation indicators, based on patent claim protection scope evaluation, and based on patent citation behavior evaluation. The following research on value evaluation indicators can focus on four aspects:further research on patent value evaluation indicators based on patent text content mining, research and form patent value evaluation baseline by field, time and type, integrate classic value evaluation indicators and new value evaluation indicators, and establish a patent value evaluation index system integrating into the patent lifecycle.

Key words： patent value evaluation; identification of high-value patents; research on evaluation indicators; patent data mining; research on patent information
