This paper proposes a new methodology for mapping the relations developed sequentially among co-author and co-inventor teams by using intellectual product databases, namely patent databases and academic literature databases, which are available to the public. The methodology is applied to analyzing the dynamics of the co-author and co-inventor relations in one of the major electronic manufacturers on the technology relating to video cassette recorders. The characteristics of charts representing R&D network dynamics are discussed. From the viewpoint of R&D management, the viabilities of this methodology for discussion various aspects are mentioned.
