Research on Patent Distribution of Three Main Chinese Medicinal Materials Such as Panax Notoginseng, Erigeron Breviscapus and Rhizoma Paridis in Yunnan Based on Industrial Chain and Technology Chain

Abstract

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.
