The bad apple in the patent basket is Apple, not Google.
They are the ones who avowed, via their deceased leader, to "go thermonuclear" in a patent war against Android.
As a result, we saw a ton of lawsuits brought up by Apple against Android or Android handset manufacturers.
Google produces Android and, the purchase of Motorola was, basically, to use it as a defense mechanism against Apple or others who try to thwart Android via litigation.
The idea is simple: if Apple sues, then Google/Motorola will give them a taste of their own medicine. Google is/was not interested and suing and didn't start this "sue happy party". Apple did. Now they need to deal with the consequences.
Maybe, in the end, Apple will rethink their retarded ways and will call a truce, which, I'm sure, Google will be more than happy to agree to.
