Is it normal in other areas of the law for the plaintiff to be able to choose the (extremely favorable) district and judge for the case? Cause I can't imagine this happening in any other area of law, either civil or criminal. It just doesn't seem right, especially when the bias is so clearly observable. IANAL though...
Normally, you pick the one that you live in, so that you don't have to travel. But for patents, many people pick East Texas, since they're more likely to get the verdict they want there.
