Hmm...I wouldn't think you'd have to give it to them - that part sounds odd. I'm definitely not in the know about these things, though. I do know that a lot of companies will not let you use their name in your domain, though.
I know of an internet marketing lawyer - I'll go dig around on his site and see if I can find something....
ETA: Ok, dagnabbit if I can't even find the guy's site! I'm pretty sure his name is Michael Young and he's in Plano, TX - he specializes in this kind of stuff.
In the meantime, though - I found a interesting, possibly helpful thread at the Warrior Forum (which is where I met the lawyer, I think - oh nooo, maybe I met him at Tony Blake's forum, yeah...) anyhoo - this thread might help you:

If you can't read that, because, you're not a member - I'd suggest signing up - the Warrior Forum is a GREAT place for people like us to learn lots and lots and lots of things. Definitely worth signing up.
Meantime - I'll go check Tony's place...
ETA: Ok, found Mike at Tony's! Here's his blog:

I hope I've been helpful to you!!
