Tang Qingzhong had always been puzzled by one question, and asked, "Why did they target Yao sister's son? Is it because Yao sister is close to us?"
Fang Yongxing stared at the belatedly aware Tang Duck with annoyance, "Don't forget who was the designer of those cups from Zhao Corporation."
It was Yao sister.
Design rights are separate from trademark and patent rights. They protect the rights of the designer. To be precise, design rights are known as copyright.
If the adversaries coerced Yao sister into asserting her copyright over her work, then Zhao Corporation's merchandise rights would be greatly affected, and even once again directly impact Zhao Corporation's reputation. This outcome would be serious, especially since Zhao Corporation had already been implicated in a similar case before, and it was something the general public was aware of.
Using this as leverage would be the best strategy.
