I am aware of the differences in legislation between the UK and US however LFL I do not doubt will be able to prove that they own the design rights because Andrew Ainsworth did not design them.He is a manufacturer plain and simple who I believe has had some very bad legal advice and thinks he can win this case.
There are a number of people who were contracted to Lucasfilm who were responsible for the design of trooper helmets and armour.
It would be nothing short of a miracle if SDS win this.I can see the damages being lowered significantly certainly but SDS will not win.
