While Shueisha has actually managed to gain registered brand recognition with some other patterns, the pattern on the clothing of the protagonist Tanjiro was not one of them. The “Rejection decision“From the Japanese Patent Office it says: “The trademark of this application corresponds to the so-called checkerboard pattern, in which black and green squares are placed alternately and repeatedly, and is intended to fulfill this function in order to identify one’s own and other products.”
The document further indicates that there is a dark line on the outside of Tanjiro’s dress squares, but it is not easy to see. Aside from that, the features of the pattern are similar to a commonly used decorative scheme, and known what makes this type of patent impossible. Shueisha still has three months to make a new appeal, but has already received brand recognition for the patterns of clothing from Giyū Tomioka, Shinobu Kocho and Kyōjurō Rengoku.
