I hate to nitpick (much), but Leading Comics was always part of the DC/National side of the DC/AA combo, so Gaines didn't own any rights to it at all, as far as I know.  All-Star Comics, on the other hand, was Leading's AA counterpart, and presumable it was those rights that Gaines would have sold/transferred to DC when he left to form EC.
