Clifford didn't care even if Heavenly Star Enterprise would think that Sy Corp copied their theme for the product showcasing. Even if they complained people would not believe them as they didn't have proof.
Besides, Sy Corp was the first one who showcased the products. Aside from that, their model was the famous Angelique Rioz. She had many fans and supporters that would support Sy Corp rather than the Heavenly Star Enterprise.
Heavenly Star Enterprise gained hatred from Angelique's loyal fans when they heard about the banning issued by the company against the supermodel. They would surely attack and bash the Heavenly Star Enterprise after this event for copying Sy Corp's theme.
Heavenly Star Enterprise originally planned to showcase their jewelry and their jewelry designs were based on the Twelve Zodiac Signs. Upon knowing this from Angelique, Clifford changed their items and decided to go for jewelry as well.
