| Summary: | 碩士 === 國立屏東科技大學 === 科技管理研究所 === 98 === According to the resources-based theory, patents are important assets of the enterprises. As companies spend their efforts on applying patents, they often ignore the facts that patents may bring the negative effects to the companies. This arouses an issue about the relationships between patents and market performances. However, this issue remains controversy to date and there is no systematically report in Taiwan. Here, we use the resources-based view to find out the relationships between patents and market performance in Taiwan enterprises.
High technology and traditional enterprises were chosen to analysis their patents and market performance. Patents applied by chosen enterprises during 2003-2009 were retrieved using APIPA -- the global patent database. Market performance is indicated by the stock price and earnings per share from 2007-2009. The patent affects the stock in the same approval year as well as three years later; and affects the EPS in the four years later. Among each type of patent, the invention patent affected the stock the most, more than the utility and the design patent; and utility patent is positive correlation with EPS which may provide a strategy for the Taiwan enterprises as well as investors.
