Hong Kong design hub PMQ under fire for art installation that looks like patented Japanese toy ‘Rainbow Sticks’
Patent holder tells Post he did not know about the exhibition in city until local art critic told him

One Facebook user said too many people “didn’t know how to respect” others’ rights, as evidenced by the strong likeness, while another suggested the Rainbow Sticks creator sue the installation designers, arguing he had grounds to do so.
More than 60 sticks of the Cuddle Bubble were placed in PMQ’s open courtyard, enabling visitors to rotate the toys such that the shiny, bell-shaped strips attached to the shafts form different shapes, including bubbles and rainbow-like patterns. This is similar to how the Japanese toy functions.
Rainbow Sticks’ patent holder, Yoshiyasu Kojima, who is Prodia’s chief executive, told the Post on Thursday he had not known about the Hong Kong installation until local art critic Joel Chung Yin-chai informed him.
