Therefore, smartphone patent infringement becomes very complicated. By dissecting smartphone industry, this research will prove the significance of the touch screen patent analysis toward one entrepreneur. It combines Decision Making Trial and Evaluation Laboratory (DEMATEL) and Clustering Method with Patent Guider which is a newly developed patent analysis tool to analyse patent citation. Commonly, the smartphone technology patents cannot be simultaneously grouped and ranked in an easy apprehensible manner. Therefore, in order to make this research become understandable to the reader, the Clustering Method will be introduced. The result of this research shows:

4. By analysing touch screen technology patent we found: Touch panel and electronic data processing got the highest investment in smartphone industry.
In addition, this research could be used as a reference source for other advanced research.
Key words: Smartphone patent, Touch screen, Patent Network Analysis, DEMATEL.
