This paper mainly analyzes the application data of patents concerning Hevea brasiliensis in the world and China from the perspectives of time, research field, and the geographical distribution of applicants. It also interprets the patents for invention in China from time, research field, and types of applicants. Based on the study, it shows that although the patent applications fluctuate, the general trend is rising. And the patents are mostly concentrated in plant protection, and agricultural biotechnology. The Chinese applicants of patents for invention largely work in the research institutes, and most of these patents focus on the field of plant protection, agricultural biotechnology, and agro-processing. However, the foreign applicants mainly work in companies, and most of these patents only focus on plant protection. These findings will provide a reference for formulating development policies about natural rubber industry in China.
