| Abstract: | The research and development of breeding technology have effectively promoted the upgrading of excellent varieties. Based on the data mining and analysis of patents related to the global maize breeding technology field from 2017 to 2021, this paper focuses on the analysis of development trends and competition trends from the main patent layout areas, obligees, technology distribution, hot spot distribution and high-value patents. The analysis shows that the United States is the leading country in patents of maize breeding technology, with patent applications and high-value patents accounting for 40% and 69% of the world respectively. Patent R&D institutions are mainly multinational seed industry groups. The patent application of maize breeding technology in China ranks third in the world. The R&D institutions are mainly consisting of scientific research institutes and universities, but there are few high-value patents, only 5.86% of those in the United States. It is suggested to strengthen the research and development of maize breeding technology and patent layout. |
