I think that some people have missed some of the points in the article in particular the aggressive litigation against Samsung, HTC, Motorola etc it isn't just Google thats being targeted. This is an anti-competitive stance, Apple, Oracle and Microsoft are being very aggressive in their pursuits. In my opinion the critical and genuine patents in mobile are linked to the radio portion of the device, the remaining patents are dubious as they don't represent novel or non-obvious solutions to a problem, more I did it this particular way so I am patenting it.

The US patent system, is broken. The cases as far as I know are being fought in the US, I doubt any of the claims would be accepted by a European court, though feel free to correct me.
