*I am not an attorney: )*
To me it seems that whoever has the best lawyers will win. Don't confuse copyright with trademark: )

My attorney put it like this:
Logos and names = trademark
Content and work = copyright

Neither are really binding until the court case happens and they are proved.

You can copyright a cd with Sgt peppers music on it. The copyright office will issue a certificate. But if you try to sell it and someone calls you on it, you will lose the court case and the copyright you have will be rendered invalid, since there is prior art which was copyrighted.

The sgt pepper's example is probably a copyright example. The record company owns the copyright to the artwork and music. The label's name on the lower corner and back, and the Beatles name are trademarked (I think...).

If booble has competent attorneys google probably doesn't have much of a shot, unless they pay off the judge.

This is just my opinion, I could be remembering wrong. I always pay my attorney to think for me: )
