Research on technological innovation opportunities based on patent analysis and technological evolution

Patent as a tool to measure innovation direction and innovation focus. Patent information can shorten the duration of technological innovation, improves the quality of technological innovation, and explores opportunities for technological innovation. Thus, this article takes patents as the starting point, and integrates methods and theories such as patent cluster analysis, technology function matrix, technology roadmap, and technology evolution theory, to build a model for identifying opportunities for technological innovation based on patent analysis and technology evolution to macro-level identify the current technology at hotspots, blank spots, and to micro-level identification of current technical routes and development. The validity of the model is verified by identifying the technical opportunities of gas turbines.
