With global environmental degradation, accelerated resource consumption, and growing public attention to environmental protection, green technologies focusing on reducing resource consumption, developing renewable resources, and mitigating pollution have become a worldwide focal point. Frequent policy initiatives encouraging green industry development have driven rapid advancements in green technologies and environmental industries. However, the creation, application, and promotion of green technologies rely fundamentally on intellectual property systems, particularly patent protection. National and international entities including the United States, United Kingdom, China, European Union, and UN Climate Change Conferences have begun exploring green patent systems through the lens of public policy attributes, aligning with goals for green technology innovation and development.
Green technologies refer to innovations that conserve resources, improve energy efficiency, prevent pollution, and promote sustainable development. Key domains include alternative energy, environmental materials, energy conservation, emission reduction, pollution control/management, and recycling technologies. China is actively developing its green patent system, notably through the 2017 Patent Priority Examination Management Measures, which explicitly prioritizes patent examinations for industries such as energy conservation, environmental protection, next-generation IT, biotechnology, advanced equipment manufacturing, new energy, new materials, and new energy vehicles.
According to the China Green Patent Statistics Report (2014-2017) released by the National Intellectual Property Administration (NIPA) in 2018, China's green innovation activities have intensified, with green patent ownership steadily increasing. By the end of 2017, China's valid green patents reached 136,000. From 2014 to 2017, green patent applications totaled 249,000, with an annual growth rate exceeding the overall invention patent growth rate by 3.7 percentage points.
The CnOpenData team has identified citations and citations received for three categories of Chinese green patents: invention applications, granted inventions, and utility model patents. These are structured into the Chinese Green Patent Citation Table and Chinese Green Patent Cited Table, providing robust data support for green patent research.
