Abstract:

The purpose of this study is to investigate the patent situation of transgenic wheat in China, and to provide reference for the R & D direction and the policy making. The patent data of the transgenic wheat had been retrieved in the SIPO patent database, and analyzed on the annual distribution, the legal status, the assignee information and the technology categories. The patent applications of the domestic applicants account for 85% of the total amount, in which the applications of the domestic enterprise account for 2.2%, while the ratio about the foreign enterprises was 83%. In addition, the patents about the adversity gene account for 52%, followed by the patents about the resistance gene and the quality gene, both with 16%. The results showed that, the patent application amount from the domestic applicants was more than that from the foreign applicants, while the domestic enterprises were still not the main force. In addition, we found that the genes on disease and insect resistance, anti-adversity and improving the quality had the problem of single function. Therefore, our government might create an environment conducive to innovative institutional mechanisms and policy environment, and gave full play to enterprises in the main role of independent innovation; and on the aspect of the technical research and development, we should pay more attention on the multi-function genes; and the enterprises and scientific research units also should strengthen the awareness of the patent protection and accomplish patent arrangements.
