The herbal medicine planting patents in Yunnan Province are retrieved by means of INCOPAT patent database and the layouts on patent number, industrial chain and technology chain of Panax Notoginseng, Erigeron Breviscapus and Rhizoma Paridis are analyzed in this paper. The layout strategies about the major herbal medicine planting patents in Yunnan are put forward from core technology, high-value peripheral technology, technology standard and regional development. The result of the research shows that to Panax Notoginseng, the core technology is the important study direction and the high-value peripheral technology must be actively arranged; to Erigeron Breviscapus, the patent layout must be guided by planting technology standard. Keywords-pseudo-ginseng; erigeron breviscapus; paris polyphylla; patent layout; industrial chain; technology chain I.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
