Analysis of the Patent Trends for Demodex

Unlike in the past, hair loss in modern society, which was regarded as a natural aging phenomenon, is caused by various factors such as genetics, male hormones, stress, nutritional imbalance, and various environmental pollution. Recently, hair follicles are known as another cause of hair loss. Such research on hair follicles has been limited mainly to the effects of hair follicles on the skin at home and abroad, and research on various attempts to remove or improve the hair follicles is relatively insufficient, especially in the beauty industry. The current state of technology using natural products under review is considered what has not been investigated. For the purpose of understanding of the current technology related to Demodex worms, we investigated the patent application published and registered patents related to Demodex and folliculitis. Quantitative and qualitative analysis was conducted by year, country, technology, and applicants based on the patent investigation results (330 valid patents). Patents related to folliculitis and Demodex were filed in 1982, and the number of patent applications increased rapidly from the mid-2000s. The number of applications in all four countries increased steadily in sequence U.S(33%), Japan(26%), Korea(22%), and Europe (19%). The objective patent information surveyed and analyzed can be used as basic data hereafter for conducting research related to Demodex.
