Yeah, this lawsuit will go nowhere. From the back of the game box in question:
"Includes Downloadable character and quest.
A $15 Value.
One-time use code available with full retail purchase.
Expires April 31, 2010."
It's explicitly stated on the box that it's a one-time use code, and something in "used" condition has been used at least once by definition, so one can't reasonably assume it would still be valid.
It also explicitly states that it's only available with the full retail purchase, which "used" copies also are not, by definition.
