Can't have it both ways. Apple hasn't been raking in money from their lawsuits, only from sales.
How much has Apple made from lawsuits vs sales?
Apple's lawsuits have resulted in quite a bit of revenue they would not have otherwise had.
At least, that's what Apple claims, since every one of their injunctions has included arguments that they would LOSE money if their patents were not upheld.
Moto sure took long enough to open their mouths about this. After it became apparent they couldn't compete with other Android OEMs, thanks to their lousy products and service, and after taking a gander at Apple's money-pile, they suddenly bring up these FRAND issues.
Motorola approached Apple in August 2007.
It is Apple that has dragged its feet, which is why the court originally granted the injunction, apparently causing Apple to decide to start to negotiate for real.
