A new classification method on the basis of a Patent-Science relationship

International patent code (IPC) and United States patent code (UPC) are the two most common classification systems in the patent database, but they have difficulties in revealing the technological characteristics of different industries. This paper proposes a new method based on a science-technology relationship, offering three main contributions: first, provide a new classification method based on the patent scientific literature; second, assist high-technology firms to measure their competitors and have foresight on future science and technology roadmap; third, analyze the technological dynamics by tracking the patent and scientific keywords.
