Patents are important literatures for scientific research and information analysis. As one of patent analysis tools, Innography has many functions such as patent retrieval, patent analysis and core patent digging. Taking organic light-emitting diode (OLED) as an example, this paper explores the value of Innography in professional information analysis and illustrates how to obtain global patents, dig core patents by patent strength index and make scientific conclusions by analysis with Innography. This paper finally summarizes the characteristics and shortcomings of Innography, emphasizing that patent analysis must be accurate and comprehensive.
