Re: the reason why Intel request to limit the lawsuit case to US only will likely fail imo is because, although misconduct might have taken place in far away Japan, US customers were wronged by it (because they also buy Sony / Tosh / NEC products).
But then again, how do you expect a judge to rule fairly in an American context when the evidence being presented was formed from a different set of standards? The U.S. is built fairly rigidly on a person or entity being innocent until proven guilty, so if anything gives reasonable doubt, the defendant is usually given the benefit of it.
And besides, if AMD's case is so weak that their U.S. based accusations can't stand up on their own, then they have no business filing a lawsuit in this country.
