Abstract The international development trend of rice molecular breeding technology was studied based on patent analysis in TI database through multiple aspects such as the number of patent applications, the application countries, the patent assignees, the life cycle of technology and the hot spots of R&D. The results showed that the technology for rice molecular breeding have developed rapidly, and get mature day by day. The United States, which has the largest number of applications worldwide, is the most valued technology market. Large Multi-National Corporations are the predominant subject for patent application. Furthermore, the patent applications from these corporations are also active in China. On the other hand, China possess more patents in rice molecular breeding technology, and has some advantages in this field. The institutes and universities in China are the predominant subject for relevant patent applications. Deep analysis of the patent documents showed that gene mining and transgenic technology for the important agronomic traits are the hot spot in this field nowadays.
