That's a lame excuse for Apple not suing Google. Oracle sued Google for using Java in Android even though google doesn't profit from android. Apple knows they have absolutely no chance of beating Google in a court room. That's why they are suing a Korean company in a court 10 miles from their HQ with local Jury. If Android was stolen, SJ would have sued Google way back in 2009. Its crazy everyone on Apple sites claim "Google stole android" yet no one can show any concrete proof.
Oracle has no option but to sue Google because their lawsuit involves operating system internals (SDKs). There's no way they could sue Samsung or others over things in the Android development environment.
Apple, OTOH, is using hardware and user interface design patents -- things which are directly visible in the products made using Android. So even though it could very well be that, technically, a user interface patent violation stems from something within Android itself (and not from what Samsung has added to it), a non-technical person would only see it as Samsung's product itself violating the patent.
So the proof is in the fact that a number of products built using Android have had user interface design patent cases filed against them.
