The Supreme Court Doesn't Understand Software
The question should never have been "why shouldn't they be able to patent it", it should always be "why should they be able to patent it".
The fact is that a patent is granted at the expense of the many for the benefit of the few, so there should always be a damn good reason for something to be granted as a patent.
GM Loses Money On Every Volt Built
If we care about GM, then we should not buy Volt from them. Every Volt we buy causes GM to lose money, so if we don't buy any Volt (boycott them) then GM won't lose any money, hence a nett positive for them. Yay
on a more serious note, I don't see why GM would market a car that causes them to lose money. How can they recoup their investment? From selling battery replacement or services? anyone care to explain?
