Yeap you're probably right, patent-trolling.
Funny you write that, since Boies is representing Oracle too. I'm generally against pure software patents, believing that most of them are obvious to a "person having ordinary skill in the art." But I haven't looked at these specific patents.
However, the copyright claims would have merit unless Google can show a clean-room implementation. Given that Android code is openly published, I'd bet Oracle found their copyrighted code in it or they wouldn't have included this claim.
