closed delaware.de domains

Hi,
is there any value for
DELAWAREINCORPORATION.DE
DELAWAREONLINE.DE
DELAWARECITY.De

the first two have hi ovt results
I thaught that the .de for delaware should be appropriate, as it is the code of the State of Delaware and all other extensions are already taken.
thanks in advance!
