Sorry, my bad. But the reality is that they do use legal muscle where it works and there have been other companies who've stated that they only bought patents for defensive purposes who soon shifted. I honestly can't see Google holding that line - you may disagree but only time will tell who is right. I'd also suggest that Google's lack of use of patents in this way so far is likely as much down to the fact that they have a notoriously weak patent portfolio (estimated to be one twenty fifth the size of Microsoft's - largely a function of age rather than intent). Google suing another large company would be taking a knife to a gun fight.
