The New York Times reports that Tiffany & Company is sueing eBay for facilitating the sale of counterfeit goods over the Internet. Undercover agents working for the company secretly bought 200 ‘Tiffany’ items in eBay auctions and found that 75% were counterfeited. The case will go to trial later this year. If Tiffany wins, the implications for eBay would be dire: imagine the costs of policing all those auctions.
