I believe the original Apple vs. Microsoft patent spat was for 'Look & Feel' as is part of the current 'Apple vs. Nokia' and 'Apple vs. HTC' patent duels.

What the legal system enables and what is 'right' are two different things.
"Look & Feel" suit was a copyright suit. At least in theory. It established that you can't copyright "Look & Feel", like I said.
