Preliminary Analysis of the Progress of Patent Research on Traditional Chinese Medicine Based on Bibliometrics

Objective To systematically investigate the development status and research hotspots of Chinese medicine patent research based on bibliometric methods, and to provide intelligence support for the high-quality development of Chinese medicine research and industry.Methods Through China National Knowledge Infrastructure (CNKI), total 842 papers on patent research of traditional Chinese medicine (TCM) in the past 20 years were collected, and they were visualized and analyzed using VOSviewer and CiteSpace software. In terms of literature chronological distribution, spatial distribution, research hotspots and evolutionary trends, we drew up a knowledge map and sorted out the research lineage to reveal the current situation and development trend in the field of TCM patent research.Results In terms of spatial distribution of literature, the 842 papers involved 334 journals, 1361 authors and 419 research institutions; in terms of development stages, the field of TCM patent research in China had experienced an upward stage (2000-2005), followed with a stable stage (2006-2020). The research on TCM group formulas ran through the whole process of TCM patent research, and the research themes were becoming more and more diversified as the research progresses.Conclusion Effective use of TCM patent information resources can promote the development of TCM industry, and the research on predicting the rules of TCM compounding and medication will become a future research trend.
