    Abstract
  • In order to fully understand the global research and development situation of bioremediation technologies, the related patents were analyzed based on Innography patent analysis platform. The number of patents, the applicant distribution, the competition situation of the applicant country, and IPC classification were analyzed. Moreover, the sources of core patents and the hot research topics were discussed. The number and development trend of bioremediation technology patents in china were analyzed. The results showed that the number of patents related to bioremediation technologies had increased rapidly since 2002 globally. The largest number of patents were from China, and the United States owned 80.0% of the core patents. The hot topics of core patents included organic pollutants, power consumption and water treatment. Maanshan Xinzhou Grape Specialty Cooperatives, Chinese Academy of Sciences, Nanjing University, Harbin Institute of Technology and Xi’an University of Architecture and Technology had the largest number of patents in China. Meanwhile, Maanshan Xinzhou Grape Specialty Cooperatives and Chinese Academy of Sciences also had strong comprehensive strength and technological innovation ability. The hot topics of bioremediation patent technology included healthcare, wastewater, bioavailability, heavy metals, and groundwater in China. It was expected that bioremediation-related research would be more focused on soil heavy metal pollution, integrated water environment management and organic pollution control in the future.
