Description
A01H covers the development of new plant varieties and the methods used to create them, including conventional breeding, genetic modification, and plant tissue culture techniques. This classification encompasses plant propagation through in vitro culture systems, somaclonal variation, and the selection or hybridization of plants with improved traits. It applies to both ornamental and agricultural plants where novel characteristics are intentionally developed or enhanced. Related but distinct biotechnological processes (such as genetic engineering at the molecular level) may be classified elsewhere depending on the specific technical focus.
Filing statistics
IPC subclass A01H recorded 86,394 patent applications worldwide between 2013 and 2023. Annual filings grew from 7,440 in 2013 to 8,109 in 2023 (+9%), peaking at 8,498 applications in 2020. The most active applicants in class A01 are CHINESE ACADEMY OF SCIENCES (6,725 applications), JOHN DEERE (6,555 applications) and MONSANTO TECHNOLOGY (6,280 applications).
