Using Patent Data to Explore Technology Trajectory and Trends of Shading Device

Abstract:

Shading devices for buildings are able to resist thermal radiation and decrease air conditioning load, this study used shading devices for buildings as an example, and conducted a patent search in the United States Patent and Trademarks Office (USPTO). This study adopted bibliometric and social network analysis methods to portray the relation between citing and cited patents, to discover the patent main path, grasping the correlation between patent technologies and the overall industrial development. The purpose of this study was to construct patent citation networks, to trace the developmental context of key technologies and their diffusion. The results suggest that automated shading devices are the focus of current technological developments, contributing to rapid advancements and helping developers save time and costs.
