Abstract
Objectives: The purpose of this study was to analyze the trend of natural product-based products for sleep improvement in Korean patents, to enhance the development and application of natural-products for sleep disorder in terms of Korean medicine.

Methods: We collected patent data using the KIPRIS database and ScienceON database. Two authors independently screened patents that potentially met the criteria, and assessed full texts of screened patents for eligibility. Included patents were analyzed, quantitatively as well as qualitatively.

Results: A total of 60 patents were selected 2008-July 2022. The number of patents have been on the rise since 2017, and reached 12 in 2018. Companies have registered the most patents, followed by the Industry-University Cooperation Foundation. Zizyphi semen (n=6), Lactuca sativa L. (n=5), Valeriana fauriei/officinalis (n=4), Poria cocos (n=4) were frequently used herbs among 60 patents. Twenty-one patents (35%) included medicinal herbs with sleep improving effects. Among 60 patents, alcohol extraction (70%) was mostly used, followed by water immersion (50%), and hot water extraction (48.3%).

Conclusions: Analysis results showed that various Korean medicine herbs, are being used for natural- products for sleep disorder. The results will be helpful towards inventing new patents using Korean medicine, developing natural product extracts for sleep improvement, and extending the range of these products in clinical use.
