Abstract

|
Objective: In this study, we analyzed the trend of patents registered prior to October 4, 2019, to understand the industrial trends in insect-derived medicinal materials used for the treatment of skin diseases.
Methods: Using the WIPSON database, we collected information regarding the patents related to insect-derived materials for treating various skin diseases.
Results: The patents registered prior to October 4, 2019, from Korea, Japan, the USA, China, and the EU, along with those registered under PCT were selected. There were 195 patents related to the use of insect-derived medicinal materials in treating various skin diseases such as psoriasis, inflammatory skin diseases, eczema, pruritus, and atopic dermatitis. China is mostly superior in total number of registered patents compared with the other countries. Korea was the major patent technology-holder for atopic dermatitis, but China dominated in the remaining categories of skin diseases. Upon first patent registration in 1992, there had been a continual increase in the number of patents. Especially, patents related to eczema, psoriasis, inflammatory skin disease were markedly increased. Most frequently used insect-derived medicinal materials was Scolopendra, Cicadidae Periostracum, Scorpions, Cantharides, and Batryticatus Bombyx. The insect-derived medicinal materials were generally used as a combined preparation with other medicinal materials in patents.
Conclusion: This study could help to establish the basis for future research and development related treating skin diseases using insect-derived medicinal materials. In order to provide sufficient data, further study including analysis of rejected patents is needed.
