Does SW still own rights to retired characters?

[muppet maniac]

I believe Sesame Workshop's acuisition of the Sesame Street characters includes the major(Big Bird, Elmo, Oscar, etc.), the obscure ones(Guy Smiley, Barkley the Dog, Forgetful Jones, among others), and even the characters from the international co-productions of Sesame Street.

Hope this helps.
