Well Google can hardly argue that MS has profited substantially off Xbox, so they can hardly expect MS to pony up large amounts of cash on that front. Windows software OTOH is a different matter.
Bad form to go suing someone when they actually licensed your patents though. On what basis did Google claim MS owed them such big sums? Was it solely because MS has made huge profits while Motorola saw only a tiny fraction of those profits in the form of license fees?
I guess FRAND is always going to be open to interpretation. Like you could say the more someone profits from using your patents the more they should pay. That's fair and reasonable from one perspective.
