Effective assimilation of intra‐technology spillover as a key to sustainable functionality: Comparative analysis of copying machine development in Canon and Ricoh

Purpose – A virtuous cycle between effective utilization of external resources and functionality development can be constructed. Given that the timely emergence of new functionality in an efficient way is crucial to a firm's competitive strategy in an era of mega‐competition, construction of such a virtuous cycle is a key element with regard to a firm's technopreneurial strategy. The purpose of this paper is to identify a trigger for such a virtuous cycle.Design/methodology/approach – Empirical comparative analysis taking copying machines development trajectories in Canon and Ricoh and the patent data analysis were conducted.Findings – Cumulative learning from preceding relevant technology development is found to stimulate intra‐technology spillover. Timely intra‐technology spillover from preceding innovation plays a triggering role.Practical implications – Attempting a broad and comprehensive learning exercise should be strongly encouraged for the effective utilization of external resources for innovatio...
