Exploring influence of R&D investment, import and export performances to patent value

Patent valuation has been an important research topic in a globalized knowledge economy where intangible assets and internationalization plays crucial roles. The objective of this study is to understand how the two factors, which are 1) intangible assets: patenting activities and R&D investment, 2) tangible goods: international import and export, influence patent value. More specifically, several patent information, e.g. Number of Patent, Number of Inventors, Number of Patent Citation Received, charge and payment for the use of patent (from USPTO and World Bank), reflecting intangible asset, together with US import and export data (from UN-COMTRADE) reflecting globalized tangible goods are employed to test if the selected data have any explanatory power in estimating patent value. The results show that the correlation is positive and the explanatory power can be confirmed.
