What is the value of internationalized patent?

This paper aims to evaluate the values of cross-country patent by analyzing characteristics of patent inventions based on international collaboration, and unveil how degree of internationalization and patent characteristics can be correlated to each other. To obtain the objective of this study, a total of 4,667,855 USPTO utility patents, comprising 457,309 Inventor-Assignee international patents, 194,633 Inventor international patents and 183,461 Assignee international patents granted by USPTO between 1976 and 2013 are downloaded and characterized, and subsequently the number of inventor countries as well as the number of assignee countries are compared with selected patent characteristics such as Number of Patent Reference, Number of Patent Citation Received, Number of Non-Patent Reference, Number of Claim. The results shows that correlation between degree of internationalization and some patent characteristics can be confirmed and therefore the value of international R&D can be more quantitatively evaluated. This paper finds out that the patent characteristics of international patents are significantly different with non-international patent, and the large number of value can be observed in international patents and finds out that more degree of patent internationalization implies that more patent values in term of patent characteristics.
