Not to be funny but I think E-bay are in the wrong here
If you were selling new Skyrunners they would be right
If I were to buy a set of skyrunners in a country where they are legal and bring them home I am breaking no laws (I might be being stupid but not a criminal
)
If I then decide to sell my legaly bought skyrunners on e-bay I am breaking no patent laws
I personaly would contact them and explain this and ask why in these circumstances they were removed
