Using patent data, a new quantitative analytical method categorizes the fusion degree of leading edge research and development (R & D) fields in order to examine the current R & D status and strategies of companies focusing in the fuel battery field, an area showing great potential as an alternative to fossil fuels. Specifically, this paper presents three types of categorization reflecting the International Patent Classification (IPC) of patent data, and introduces the concept of "innovation positions" which is based on this categorization. For example, application purposes can be different between various industrial sectors, even within the same technological field; therefore, the progress status of R & D varies and that fact. is reflected in innovation positions. Additionally, this paper makes clear that innovation positions reflect differences in companies' core competences, even in the same industry. This analytical method provides an original approach to comprehend technological linkages and innovation.
