An Analysis of Aconiti Ciliare Radix Patents

Objectives: The purpose of this study is to investigate and analyze Korean domestic patents on aconiti ciliare radixand to identify the trend of aconitum tuber technology.Methods: To analyze the patent, a combinations of words such as “aconitum” or “korean aconite root” were usedin search engine Kipris(www.kirpis.or.kr). The patents of aconiti ciliare radix were analyzed in three ways: year trendanalysis, internatonal patent classification (IPC) code analysis related to content classification, and patent registrationstatus analysis.Results: Among the patents found in the search results, 17 patents with significant contents were analyzed. Resultsshowed that, first, patents were steadily registered until 2018, but recently there has been no new patent registration.Second, there were many patents related to efficacy verification and decoction method, and the number of IPC codesrelated to them was also high. Third, there are five patents maintaining the registration status, and they are patentsrelated to the aconiti ciliare radix extraction method, toxicity removal, and combination method.Conclusions: In this study, the domestic patents of aconiti ciliare radix were analyzed. The analysis results of thisstudy are expected to be exploited as basic data for the development of Korean medicine analgesics with fewer sideeffects by suppressing tuber toxicity and the creation of new medical technologies.
