Well this explains it right here. Sounds reasonable to me. Since the three employees have no money, Moto has to go after the deep pockets.
During the trial, Hytera attorneys acknowledged that three former Motorola [the company had not yet changed its name to Motorola Solutions at the time] employees—Samuel Chia, Y.T. Kok and G.S. Kok—accessed more than 7,000 Motorola documents prior to each of them leaving and joining Hytera shortly in 2008. However, Hytera attorneys described the three engineers as “bad apples” who did not share with anyone else at Hytera that the DMR trade secrets and software were taken from Motorola.
