Android tablets are being pulled from shelves. What should they do? Just concede the market to Apple for the decade or so a serious attempt at patent reform will probably take? They're still not offensively suing anybody.

It is a vicious circle, I agree with you.

But it's not clear how Google can break the cycle by themselves. If Google were to say no to patents, without there first being major reforms to the patent system, then they would be slowly squeezed by their competitors patents until they ran out of juice.
