<<take a look at the Mobil/Amoco case of 1994. In that instance Mobil wasn't even trying for the whole amount - they tried to claim 1/2 the savings to Amoco as a "reasonable" royalty.>>
Post a link, please -- Is this royalty due the owner of a depleting asset, that is, oil in place in the ground? If so, I wouldn't think it would have much bearing on how royalty is calculated in cases of ownership of intellectual property or an invention.
