Which is exactly why they don't want the patent system abolished or dramatically crippled right now. I don't think Google would care as much if the patent system is abolished. As far as I know they don't license their technology to others and they haven't sued others for patent infringement. They only use them as a defense against others, but it would be a win for them if all software patents would be abolished. They might not push for exactly that right now, but I don't think they would be very upset about it if that happened.
