The limits of copyright law
[Commentary] Courts shouldn't assume that copyright law was designed to protect copyright holders' slowly evolving business models. If Congress wants to outlaw the kind of "gray market" importing that Kirtsaeng practiced, it can do so explicitly. But there are many other industries that have found ways to deter those practices without the aid of copyright law — for example, by using contracts to keep tight control over foreign retailers. Courts have to balance copyright holders' interests against the public's ability to access those works and exercise the rights of ownership. In the Kirtsaeng ruling, the justices restored that balance.
