Latest Patents

Kichikawa’s listed patents address two distinct applications of information processing.

“Information processing system, information processing method, and non-transitory computer-readable recording medium” describes a system for analyzing how influence passes through capital-investment relationships among connected entities. It uses capital contribution ratios along paths between nodes to assess influence. When one higher-level node holds more than half of the relevant contribution ratio, the system identifies that node as effectively controlling the analysis target.

“Information processing system and method of information processing” concerns the analysis of supply-chain networks, where nodes represent companies and links represent product-supply relationships. The system extracts upstream or downstream subnetworks around a target company, represents nodes with complex vectors, and calculates similarities between companies based on those vectors.
