I wouldn't bank on that he's a sneaky SOB the fact he's stil in business producing stormtrooper and other helmets and armour despite not winning the case LFL bought proves that.
I'd bet he has found some kind of loophole here i'd just like to know what it is.
He didn't win the case but he didn't lose it either.
The judge held the original stormtrooper helmet was not on proper construction of English copyright law capable of attracting copyright. This was because to do this a 3 dimensional object has to either be "sculpture" or a "work of artistic craftsmanship." The judge held they were neither. If there is no copyright there can be no infringment of it.
I won't go into detail about the reasoning as they issues are complex and drawn out, but I would be shocked if Lucasfilm doesn't appeal on the basis the judge got his interpretation wrong.
Objects which are not copyrightable such as this can rely on what are known as industrial design rights to protect them. This protection is limited to a maximum of 25 years, and only then if registered. If unregistered they expire after 15. Any protection offered here would have lapsed long before SDS began manufacturing its replicas.
The helmets cannot be patented or trademarked either.
What this decision in fact means is until a higher court rules against this decision, pretty much any prop made more than 25 years ago is fair game at least as far as English law is concerned. There is no enforcable intellectual property right as the law deems them to be objects of industrial design and only offers protection for a limited time.
If there is a loophole, this is where it is.
As AA refused to accept the jurisdiction of the US courts and he does not have sufficient presence in the US to compel him to accept it, the English courts cannot enforce the US judgment. He ruled however that in certain circumstances an English court can rule on foreign copyright law providing there are no issues of substance to be decided.
This may well be the case here, but it is unlikely that US modes of damages would be used. In English law you can only claim for the damages suffered directly because of the wrongdoing, and those reasonably forseeably arising from it. I also doubt it will cover any damages suffered outside of the US. The most I can see him having to pay is the amount obtained from the US sales. I may well be wrong on this point though.
It seems at least for now AA and any other would be prop maker in the UK is free to make stormtrooper armour without fear of reprisals within the UK. This position may change on appeal.
I hope this isn't too full an answer to your question.
