Ainsworth is actually claiming he OWNS the rights to the design of the trooper helmets and armour and he is countersuing Lucasfilm for a share of the merchandising from the Star Wars films.He claims he not only fabricated but designed them into what we know as the stormtrooper.
Unlike Parks sabers where the term lightsaber,which is trademarked,was the contention the sabers Jeff Parks actually sold were different enough from the movie designs that he could get away with it by shortening to the term saber.SDS are selling exact replicas also using trademarked emblems without license.Honestly he hasn't a hope in hell of being able to prove that those designs are his intellectual property.
