    As technology development has become a core competence of firms in knowledge and information-based society. Firms are interested in patent application in order to take the leading position in technological competition. Consequently, patent statistics are used as proxies for technical competitiveness. Patenting has become an outstanding issue for Korean firms and the number of patent of Korean firms has risen dramatically since the early 1990's. The purpose of this study is to investigate the determinants on patent application, focusing on firm's R&D expenditures. Thus, this study examines empirically hypothesis concerning (1) the relationship between firm's R&D expenditure and patent application, (2) the effect of internal factors on patent application, and (3) the effect of external environment factors on the relationship between firm's R&D expenditures and patent application in manufacturing firms listed in Korea Stock Exchange over the period 1984-2000. The results of this study are as followings : First, there was statistically significant and positive effect of R&D expenditures on the patent application since 1989. R&D expenditures are generally regarded as the most important factor determining patent application. However, firms haven't considered the patents as a measure of R&D performance until international trend in technology has formed a new order on the basis of the industrial property rights in the framework of the WTO/TRIPs. Second, there have been a controversy in the effect of firm's internal factors, such as capital intensity and firm size on patent application. The effect of firm size on patent application was statistically significant and positive, while the effect of capital intensity on patent application was statistically negative or insignificant. That is, it was easy for large firms to patent because large firms supply R&D department with an abundance of financial and human resources and knowledge. Third, the effect of R&D expenditures on patent application in high-tech firms was greater than that of other firms. In addition to the effect of R&D expenditures on the patent application after patent protection strengthening was greater than before, but this effect was limited to firms in high-tech industries. The finding implies that patent protection strengthening of the WTO/TRIPs made firms in high-tech industries concentrate on patenting.
