Abstract: As a traditional Chinese medicine,Polygonatum sibiricum has important medicinal value,edible value and economic development value. Based on the Innography patent analysis platform,this paper not only discussed the development trend of global and Chinese P. sibiricum from the perspectives of patent applications,patents layout,technology source,competitive situation and IPC technology category,but also further analyzed source and patentees of core patents,and technical hotspots based on exploring the core patents in this field. Studies have shown that worldwide P. sibiricum research is in a period of rapid development,and China owns a large number of patents in the field and controls the most core patents. P. sibiricum related patents are mainly applied by enterprises and related technologies are mainly concentrated in 4 enterprises in Qingdao,Zhejiang and Shandong. The application area is mainly distributed in IPC-A department and the main directions are herbal formula containing P. sibiricum,extraction of active substances and development of alcoholic beverages. The result may provide an important reference for comprehensively understanding the development of P. sibiricum research and formulating scientific industrial development policies.

Key words: Polygonatum sibiricum., Innography, core patent, patent analysis, technical situation
