In a lawsuit filed in Paris, LVMH Moet Hennessy Louis Vuitton SA has launched a legal attack on the world's biggest online auction site, claiming that eBay has not done enough to stop the sales of counterfeit goods through its site. France makes an appealing venue for the suit, not just because LVMH is a French company, but because of France's tough anti-counterfeiting laws. Central to the case is the question of who is ultimately responsible for ensuring that counterfeit goods do not come up for sale.
