I’m just going to refer you to the excellent diagram above for your lesson in force feedback lawsuitology. The outcome is basically that Sony ended up paying a bunch of money, Immersion came out on top for the most part, and Microsoft is still richer than Croesus. It’s finally been settled, as Microsoft got their ounce or so of the pound of flesh that Sony had to deliver to Immersion. In bed.
Years ago when this whole rumble started, I thought it would disappear faster than a crack-spiked birthday cake. Years later, two industry giants are paying nine figures. I guess the lesson to be learned here is: with enough lawyers, anything is possible.
