Given the nature of the Sony rule, it is not surprising that in the last 20 years, there have been relatively few contributory infringement suits—based on a product distribution theory—brought against technology providers (a small handful of federal appellate court cases and perhaps fewer than two dozen District Court cases in the last 20 years). I have found nothing in the briefs or the record that shows that Sony has failed to achieve its innovation-protecting objective.

The second, more difficult, question is whether a modified Sony rule (or a strict interpretation) would significantly weaken the law’s ability to protect new technology. Justice Ginsburg’s approach would require defendants to produce considerably more concrete evidence—more than was presented here—to earn Sony’s shelter. That heavier evidentiary demand, and especially the more dramatic (case-by-case balancing) modifications that MGM and the Government seek, would, I believe, undercut the protection that Sony now offers.

To require defendants to provide, for example, detailed evidence—say, business plans, profitability estimates, projected technological modifications, and so forth—would doubtless make life easier for copyright holder plaintiffs. But it would simultaneously increase the legal uncertainty that surrounds the creation or development of a new technology capable of being put to infringing uses. Inventors and entrepreneurs (in the garage, the dorm room, the corporate lab, or the boardroom) would have to fear (and in many cases endure) costly and extensive trials when they create, produce, or distribute the sort of information technology that can be used for copyright infringement. They would often be left guessing as to how a court, upon later review of the product and its uses, would decide when necessarily rough estimates amounted to sufficient evidence. They would have no way to predict how courts would weigh the respec-
