Prior to 2009, graphene-related patent technology was at its infancy; after 2010, the number of applications for graphene-related patented technologies grew rapidly. The "Annual Report" believes that the current multi-national governments have vigorously promoted the research and industrialization of graphene in order to compete in a forward-looking and strategic manner. Patent layout.
According to statistics from Jiangnan Graphene Research Institute, as of December 31, 2017, the total amount of global publicly available graphene patents was 60,874, an increase of approximately 20% over the same period of the previous year. Among them, China had the highest number of patent applications, and patent disclosure amount was 37,249. It accounted for 61% of the total, ranking first in the hierarchy. The number of patent applications in the United States and South Korea was the second highest, with the disclosures being 8,024 (13%) and 6,249 (10%) respectively, ranking second in the hierarchy. Japan, Germany, the United Kingdom, France and other patent applications are relatively few and are ranked in the third tier.
According to the analysis of the "Annual Report", from the perspective of the technical composition, graphene patented technology focuses on the preparation of graphene raw materials, energy storage (batteries), composite materials, sensors, transparent conductive films, touch screens, transistors/integrated circuits, electronic information, etc. Application areas. China has the largest number of patents in the field of graphene preparation and energy storage applications, with emphasis on basic applications; developed countries such as the United States and South Korea pay more attention to basic theoretical research and prospective patent layout for future high-end applications.
According to the "Annual Report", most of China's graphene patents are filed domestically, and the layout of foreign patented technologies is relatively weak. Although China has also begun to attach importance to patent overseas applications in recent years, the overwhelming majority of countries are using the United States as their target country of application. planning.
The “2017-2018 China Graphene Development Annual Report” was jointly developed by the China Economic Information Society and the Jiangnan Graphene Research Institute. It aims to systematically analyze the new development trend of the global graphene industry and provide important reference for industry, academia and government.
