I am not aware of any published statistics concerning damage awards for breach of a non-disclosure agreement. I am not aware of any published statistics concerning the granting of equitable relief for breach of a non-disclosure agreement. All I have to go on is anecdotal evidence, my colleagues' and mine. It's not a pretty picture. Except in the case of a most flagrant breach, most defendants get off with a rap on the knuckles, if not scot-free.
Courts are loathe to award significant monetary damages for breach of a non-disclosure agreement.
Reflect upon this if you will. No such case comes to my mind. I keep fairly close tabs on these matters too. As hard as it is to prove breach of a non-disclosure agreement, harder still is it to prove damages sustained from such breach. Don't fool yourself.
