This paper discusses technological aspect of TI's strategy focusing on DSP, based on an empirical analysis of its patents trajectory. It is observed that TI's top management's strategic decision in early 1990 to focus on DSP had revitalized R&D activities for DSP. By analyzing the trend of TI's patent share, this paper clarifies that its R&D activities for DSP were very active not only in 1990s, which are widely known, but also in 1980s. It means that TI's R&D activities for DSP had double peak periods. From the citation analysis of TI's patents, it is observed that TI had internally accumulated, transferred, and intensified the DSP knowledge during the periods.
