The technology covered by the ‘073 patent has been incorporated into the series of Bakugan rollable toys developed by Spin Master and released in 2007 in conjunction with the Japanese-Canadian anime adventure series Bakugan Battle Brawlers. According to Spin Master’s complaint, the Bakugan toy series has been a major success for the company, earning $1 billion in sales in just over a decade. Bakugan is a combination of the Japanese words for “to explode” (baku) and “sphere” (gan) and Spin Master’s toys were designed to be spherical, rollable toys which would “explode” into a character when the toy came into contact with a magnetic component. Spin Master’s toys remained popular through a number of Bakugan spin-off series and the company planned to reboot the toy brand for release along with a new anime series to be released in the 2019-20 time frame.
