Obviously, Sony never owned Daredevil but the rights were still associated with him in order to make the Daredevil movie.
The Daredevil movie was made by Fox.
And the rights to Kingpin were "loaned" to FOX by Sony to make Daredevil, probably for a monetary price. Daredevil has since returned to Marvel, but whether or not Marvel owns Kingpin is still something for contract lawyers to argue. Either way, Marvel has other properties to explore on film, so Kingpin isn't necessary.
FWIW, Sony has stayed away from Kingpin, too. The waters are probably too murky and not important enough to wade through.
