This study proposes a new approach on how to analyze business trends from business model patents. From IPC:G06Q(Business Model) patents in mobile industry, we analyzed abstract data using Association-Rule Text Mining and Co-Occurrence Matrix analysis. Those two techniques were complementary to each other, and we could find out the trends of mobile industry. We also suggest CASA plot, which is a great method to illustrate the service trends. It includes the informations of keyword-importance, frequency and centrality. Using CASA plot, we could have a single view of the understanding movement in mobile industry by year.
