Abstract: In patents a great number of technical inventions are documented. Aided by the theory of inventive problem solving, such inventions can be analysed in a specific manner, which gives insight into inventors' thoughts. In particular, so-called inventive principles facilitate an investigation of thinking. To-date, there are 40 acknowledged inventive principles. In a case study, the field of solar cell modules was selected for an analysis. This paper will present: i) methodical aspects of the study; ii) results concerning the similarities and differences in thinking of Japanese and European engineers, measured by means of the types and frequency of inventive principles they used. A portfolio will show three different clusters. The presented method offers extensive knowledge analysis and also creation opportunities opens up also a strong link to strategic technology management, e.g., illustrating similar and different competencies of institutions in an early merger or acquisition phase.
