Marvel and DC Comics have lost their long-held 'Super Hero' trademark exclusivity after decades of successfully defending it.

Marvel and DC have jointly held the trademark for the word "superhero" since 1980, but no longer. The United States Patent and Trademark Office, in response to a petition from Superbabies, Limited, has canceled the trademark.

The U.S. Patent and Trademark Office has shaken things up in the world of comics today, as a long-held trademark by Marvel Comics and DC Comics has now been canceled. The announcement comes courtesy of law firm Reichman Jorgensen Lehman & Feldberg (RJLF),
