Mapping Technological Trajectories for Energy Storage Device through Patent Citation Network

Abstract

Technological innovation is a well-known opportunity and it has given the new concept to the competitive era and makes the world easy. It is applied to technological evolution and scientific principles consideration. The innovations in any field occurred where the innovative paths provided by technological trajectories. Further, these technological trajectories are analyzed by the descriptive analysis whereas, the knowledge flow of a technology from one country, institution or corporation to another has been used as a method of identifying by analyzing the patent citation network. It is argued that the quantitative method is used for mapping the technological trajectories and patent citation network. This paper addresses the patent citation network and its bibliometric analysis that are used to monitor the technological trajectories for energy storage device (ESD). The current research focuses on the enhancement and growth in the innovation of energy storage device. The scope of study focuses on the list of patent classification according to the International Patent Classification (IPC) has been used to identify the ESD patents by searching in the United States Patent and Trademark Office (USPTO) database. Further, the scope of this study focuses on key innovation for the energy storage device and its technological trajectories can be considered as patent citation network. Further, it provides the way to develop the main path technology for the industry.
