Some NDAs are worded to excluded any information available publicly attainable from third party or if the client makes it public.

I make you sign an NDA to hear my TOTALLY REVOLUTIONARY idea. You sign it. And then I tell you, we're going to do [incredibly obvious thing related to your current business].

If you then go and do it (like I said, it was obvious) I sue you for taking my idea.

Oops?
