We developed a method to identify core technologies that are important in formulating technology strategies and business strategies using technical information. We narrow down core technology area by using File Index (FI). of the target company's patents as the technical field, extract the candidate by text mining, and specifically identify the specific core technology using the non-patent information. Specifically, we first narrow down using the living application share within FI and the own citation ratio of the application. After that, by text mining focusing on the problem in the patent application specification in the FI, the technical problem is extracted. Then we will identify core technologies from FI and technical issues. Finally, we verify the core technology using a wide range of non-patent information such as papers, magazines, and the Web. We think that this is useful as a method to extract and identify the core technology because it can be used by staff who are not familiar with technology and patents.
