PASJDWhile I am not an intellectual property expert it sounds odd to me, akin to Rolex trying to prevent someone from selling a used Rolex. Rolex could stop you from selling a fake, but not a genuine one, I would imagine, unless you set yourself up as an unauthorized dealer. I would write them, in a polite way for starters, asking them exactly what it is they say you have infringed and asking them to cite you what statute they are relying on.
