Google lost about ~$9 billion on Motorola (~$12 Billion acquisition and now a ~$3 billion sale). This happened in the span of 2 years. You could throw $100 over your shoulder every second for those two years and that still wouldn't amount to $9 billion.
We're the patents really worth that much?
Edit: To anyone who uses the recent news about Google being forced to pay a percentage of their AdWords revenue to a patent troll: couldn't you spend $9 billion on lobbying to end this whole disaster of a patent system forever?
