Abstract Based on the patent information in the DII database, using patentometric research methods, a statistical analysis was made on the transgenic soybean research patents which was indexed from 1963 to 2012. Aimed to show the development status,the focus of R & D and the distribution of transgenic soybean technology. The patent analysis of transgenic maize (the data from DII ) are carried out using TDA and MS EXCEL.
