Immersion Corp, which owns the patent on 'rumble' technology, has won another round in its suit against Sony
. Sony's 'dualshock' controller has used rumble technology for years, and in 2005 a judge awarded $82 Million to the patent-holder in payment. From the article: "Sony's defence was the alleged nondisclosure of some of the inventions of key employee Craig Thorner. who has been a consultant both for Immersion and subsequently for Sony. But, according to the report, U.S. District Judge Claudia Wilken was unhappy with Thorner's testimony supporting Sony, given that he had also been paid by Sony, and so dismissed this line of defence."
