Using patent information analysis to examine the development of blockchain

Abstract

The previous literature on blockchain focuses on its technological principles and characteristics, broad application scenarios, and industrial development. Only a few studies conduct patent information analyses, and even fewer investigate the technological opportunities of blockchain. Through patent analyses, the authors identify the technology activities and potential areas of technology development of blockchain, and thereby make patent roadmaps. Technology-Effect Matrix and Distribution Difficulty of Technological Effect are used for further analysis. This study contributes by examining the current development of blockchain, predicting the potential areas of future development, and providing some suggestions for public policymaking and research and development strategising of innovators.
