Google lashes out at Oracle. Is anyone surprised?

So the other shoe has dropped and Google has now legally responded to Oracle's lawsuit on alleged Android patent infringement on Java intellectual property issues.

It's a 27 page legal filing, but let me summarize it succinctly for you. Google is denying Oracle's claims of patent infringement. Going a step further, Google is questioning the validity of Oracle's patents

Is anyone surprised? Well they shouldn't be.

Back when Oracle first filed there lawsuit, Google sent out a statement that said they would defend open source standard and called the Oracle lawsuit 'baseless'.

The way I read Google's response is that this will become a case about patent validity, which will ultimately have much wider repercussions than than just the Google/Oracle case. This case will test some the patentability of one of the most popular development languages.
