Abstract
This paper aims to propose a new kind of patent roadmaps, including a roadmapping method and application directions. The patent roadmap is used to analyze patent competition and develop a patent strategy. In the patent roadmap, patent analysis, patent maps and a generic technology roadmap are used. By using these three methods in combination, two concepts, patent information and patent strategies, are linked. Further, the patent roadmap provides theoretical and informational support for companies, allowing them to learn about the current patent competition situation, and perform corresponding patent layout planning. Compared to previous research on technology and patent roadmaps, this study illustrates the patent competition situation in some industries, and provides a new method for patent strategy planning and its applications. In a case study, this paper presents the patent roadmap of the high-speed railway track (HSRT) industry, specifying the whole roadmapping process and an application in patent planning. Finally, conclusions are drawn that, in applications, the proposed patent roadmap not only plays an important role in helping companies to find new technology opportunities, avoiding duplicate R&D investments, preventing patent infringement risks, and so on, but also has important significance for guiding the overall industry development.
