The US Supreme Court this week will be judging whether or not the First Sale Doctrine applies to products produced and purchased outside the US. Can you buy an iPhone, a book, or video in China and sell it in the USA?

"The first-sale doctrine allows the owner of a lawfully made copy of a trademarked or copyrighted good to sell or dispose of that copy without obtaining the permission of the copyright owner. For example, a mother who purchases a DVD of a popular children's movie can sell that DVD at a yard sale a few years later without the permission of whoever owns the copyright."

When you buy something do you own it?  See:
