This was the first Taiwan cultivar to be patented in Japan. The rights are held jointly by NCHU and the Japanese company Hanakongou. NCHU didn't put up any money for the patent, but it is receiving ¥ 10 for each plant sold.
此一台灣育種、在日本申請品種權的先例，最後達成「台灣的產權歸中興大學，日本產權則為中興大學與日本華金剛株式會社各半」的共識，中興大學不必出資，即可坐收每賣一株收取 10 元日幣的權利金。
