Law.com published an excellent article by Besunder and Sherwin on March 18, 2009 concerning a legal dispute between Tiffany Jewellers and eBay that has been winding through the US courts for some time now. The case concerns liability for the sale of counterfeit goods via the Internet.
Counterfeit goods are products that are sold in association with a trademark without the authorization of the trademark owner. Its the most subversive form of trademark infringement.
As discussed in detail in the article, the heart of the issue is whether Internet auction sites - like eBay - have a positive duty to investigate potential infringers and prevent the sale of counterfeit articles on their web site and, if so, when that duty may be triggered.
Its reported that eBay's official policy on counterfeit goods is a "notice and take down" regime. This requires trademark owners to monitor the eBay web site and give it notice of each instance where counterfeit goods are advertised via the web site. For many brand owners, this type of policy may be satisfactory. However, this policy is less satisfactory when counterfeit goods for one brand are routinely sold via the web site, in some cases by repeat offenders.
According to the article, Tiffany reported 20,000 instances of counterfeiting to eBay in 2003 and 135,000 in 2006. It argues that eBay cannot avoid a positive duty to police potential infringement in these circumstances.
While the law generally does not impose liability on "common carriers" like telephone and courier companies for the actions of their customers, the law generally does not condone willful blindness either. My expectation is that the court will find a solution in the middle of the two positions and impose liablity on eBay beyond a certain threshold.
The difficult policy question will then be where that threshold should be placed and how it should be triggered. Some trademark owners fail to police their marks at all so it would be nonsensical and unfair to place that burden on eBay. However, where a trademark owner does actively policy their mark, there has to be a tipping point where the routine sale of counterfeit goods on a single web site should not be tolerated by either the trademark owner or the operator of the web site. In the long run, its bad business of everyone.
