With the growing popularity ofDemon Slayer: Kimetsu no Yaiba, manga publishing company Shueisha has been appealing to the Japan Patent Office to patent six designs that appear on different characters' clothing. The Japan Patent Office has stated repeatedly that the designs are too simple to be able to patent.
In the latest appeal, three of theDemon Slayerdesigns were finally approved for a patent. The designs include those forDemon SlayerHashirasTomioka, Shinobu, and Rengoku. The other three designs, which belonged to main character Tanjiro, his sister Nezuko, and demon slayer Zenitsu, were denied again due to a lack of complexity and defining markers. Shueisha will have three months to appeal again, this time to the Commissioner of the Patent Office.

The designs from Nezuko and Tanjiro’s robes are actually historically recreated designs from the 18th century in Japan, and that is part of the reason they were denied a patent. For instance, Nezuko’s robes consisted of a black and teal-colored checker pattern. This pattern was used often in the Edo period of Japan and kabuki actor Sanogawa Ichimatsu owns an 18th century period costume bearing the same exact pattern. Nezuko’s robes are light pink with geometric shapes forming a sort of flower-like appearance. It was noted that this print very closely resembles the asanoha pattern, which represents hemp leaves from the Heian period of Japan. The design was often used for young childrens' kimono’s and was ironically used to ward off evil.
Fans ofDemon Slayerknow thatNezuko is a young girlpossessed by a demon, but she is able to assert her will over the otherwise brutal and violent urge to kill. Perhaps this protecting pattern helps her achieve this. Meanwhile, Zenitsu’s pattern has no historical significance but simply is too lacking in originality to garner a patent. The design consists of an ombre orange background with small white triangles dotting the design.
Legal annoyances are nothing new to the ever-popular franchise, especially after theanimation studio Ufotable was accused of tax evasion. The patent of the designs is not an incredibly important detail, but will surely allowDemon Slayerto have better control over merchandise and other goodies made using the patterns.
