This paper mainly analyzes the application data of patents in 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 finds that although the patent applications fluctuated, the general trend is rising. And the patents mostly concentrated at 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 agriculture products processing. However, the foreign applicants mainly work in companies, and most of these patents only focus on plant protection. These findings will provide some references for the formulating development policies for natural rubber industry in China.
