Is Online Copyright Scalable?

Annemarie Bridy, University of Idaho College of Law

This Article examines P2P file sharing and the copyright enforcement problem it has created through the lens of scalability. Part I traces the evolution of peer-to-peer (P2P) networks from Napster to BitTorrent, with a focus on the relative scalability of successive architectures. Part II takes up the difficult question of the scale of P2P infringement and its harms, examining the strategic number crunching that underlies industry data on piracy, the government's credulous acceptance of that data, and the risk of letting industry hyperbole drive copyright policy and law enforcement priorities. Part III evaluates the efficacy of the Digital Millennium Copyright Act (DMCA) as a policy mechanism for scaling up online copyright enforcement. I argue in Part III that the DMCA has proven to be remarkably scalable for enforcing copyrights in hosted content but has altogether failed to scale in the context of P2P file sharing, leading to the dysfunctional workaround of mass John Doe litigation. Part IV weighs the costs and benefits of more scalable alternatives to mass litigation, including a potential amendment of the DMCA's prelitigation subpoena provision and a pair of administrative dispute resolution systems-one hypothetical, the other real-for streamlining adjudication of P2P infringement claims.
