The article introduces a new patent roadmap method to help companies analyze patent competition and plan patent strategies. By combining patent analysis, patent maps, and technology roadmaps, the patent roadmap links patent information with patent strategies. The study shows how this method can help companies in industries like high-speed railway tracks to understand patent competition, plan their patents effectively, and avoid duplicate research investments or patent infringement risks. The patent roadmap can guide companies in finding new technology opportunities and contribute to the overall development of the industry.
