The judge previously held a hearing in January, where several companies attempted to defend their actions -- Luckern found that 750 models of cartridges infringed on at least one of 11 Epson patents.

The ITC will make a final determination in the case on July 30.
Seiko Epson has reached settlement agreements with seven suppliers, as agreements are expected to be reached with several other companies soon. The company has already filed similar complaints in China and England, already settling some of the cases.
