Sony sued again over controller rumble
Published on
Sony may have settled its patent case with Immersion of DualShock rumble, but it's not out of the woods yet. Craig Thorner, an engineer who held a few patents related to the firm's rumble tech, is now suing Sony, claiming the PlayStation-maker colluded with another firm to make him accept "unfavourable terms" in the Immersion case, one he appeared in as a witness.
The Immersion case dragged to a close in 2007, but Thorner claims he was hoodwinked by a group of lawyers who were acting for Sony at the time.
