Abstract: Automated crop phenotyping is of great significance for modern crop cultivation. To explore the rapid development of this technology in recent decades, a search strategy combining IPC and keywords was used to retrieve a total number of 3 977 automated crop phenotyping patents from the Patsnap global database. Analysis and evaluation were conducted from the perspectives of application & authorization patent overview, technology life cycle, innovation geography, technology branches, major innovators, major innovation subjects, and overseas patent layout. Results show that the number of patent applications for automated crop phenotyping experienced a rapid increase, especially after 2015. On a global scale, technological innovation mainly originates from East Asia and the United States, with China and the United States leading the field. From the perspective of domestic distribution, technological innovation mainly originates from Beijing, the Yangtze River Delta, and the Pearl River Delta. Technological branches in this field mainly include pattern recognition, image processing and analysis, system integration, sensor application, and computer modeling application. The leading innovators include large transnational corporations, universities, and scientific research institutes. Foreign innovators generally pay more attention to the diversification of R&D direction and overseas patent layout than domestic ones. The research results can provide references for government departments and relevant R&D institutions.
