[Purpose/significance] At present, whether some patent evaluation indicators can be used to evaluate the potential for industrialization is still controversial. This paper checks the efficiency of the chosen reasonable evaluation indicators, especially analyses the feature of Chinese patents, and compares the differences of evaluation indicators of industrialization potential between domestic and foreign patents.[Method/process] Based on a comprehensive literature reviews of worldwide research work, this paper proposes evaluation indicators of patent industrialization potential from three value modalities including technique, legal rights and market, and the efficiency of the evaluation indicators are tested by quantitative methods, such as independent-samples T test using SPSS.[Result/conclusion] Chooses patents bought by patent trolls as samples of foreign patents, Chinese transferred or licensed patents as samples of domestic patents. For these proposed indicators, the verification result is: there is a big difference at evaluation indicators of industrialization potential between domestic and foreign patents.Through the empirical study, there are some evaluation indicators can be used to value industrialization potential for foreign patents, including relative citation frequency, number of non-patent reference, number of IPC Classification, number of claims, patent family size, patent age, "whether renew at the 8th year after patent grant"; some evaluation indicators can be used to value industrialization potential for domestic patents, including patent type, "whether renew at the 5th year after patent grant".
