Trade Mark protection as usual.  It is not about naming the cursed word; it's 
the way you mention it.

Of course you are not talking with your attorney hat here.

Just take it a bit out of context (as a lawyer would probably do):

Attorney: What's a User Agent String?
Expert: Well, it's the way the browser identifies itself against the server.
A.: So, can I say it's like me asking you "Who are you" and you answering 
me "I'm Mr. Smith?"  or "what's that? is this a Pepsi or what is it?"
E.: Well... I'd say that...
A.: Just answer yes or not!
E.: Hummm... Err... Well, yes.
A.: So then, Iceweasel is claiming to be "Firefox" against the server which 
asks it?
E.: Yes.
A.: It is not answering "I'm *like* Firefox" or "My codebase is based on that 
from Firefox" but "I'm Firefox"?
E.: Yes.
A.: No more questions.

Forget it's only machine to machine chatting and think for a second the 
user-agent string were on a newspaper.  I think it's clear that "Firefox 3.5" 
would be an obvious copyright infringement while "Based on Firefox 3.5" would 
be perfectly safe.
