This isn't about patents, it's about copyrighted artistic works. That's the reason Windows doesn't look like the OS X.I don't believe it, why doesn't apple sue the apple fruit then?

gOS rips off leopard? what do you think leopard is? a stack+a dock? get real!
Apple would have sued and stop gOS from ever appearing in the market! if apple has that patent.
and guess what? they didn't. apple does ripping off all the time as well. In case you forgot.
This is clearly a case of prior art.
