Breyer, J., concurring

so, would new or necessary copyright-related benefits outweigh any such weakening?

A

The first question is the easiest to answer. Sony’s rule, as I interpret it, has provided entrepreneurs with needed assurance that they will be shielded from copyright liability as they bring valuable new technologies to market.

Sony’s rule is clear. That clarity allows those who develop new products that are capable of substantial noninfringing uses to know, ex ante, that distribution of their product will not yield massive monetary liability. At the same time, it helps deter them from distributing products that have no other real function than—or that are specifically intended for—copyright infringement, deterrence that the Court’s holding today reinforces (by adding a weapon to the copyright holder’s legal arsenal).

Sony’s rule is strongly technology protecting. The rule deliberately makes it difficult for courts to find secondary liability where new technology is at issue. It establishes that the law will not impose copyright liability upon the distributors of dual use technologies (who do not themselves engage in unauthorized copying) unless the product in question will be used almost exclusively to infringe copyrights (or unless they actively induce infringements as we today describe). Sony thereby recognizes that the copyright laws are not intended to discourage or to control the emergence of new technologies, including (perhaps especially) those that help disseminate information and ideas more broadly or more efficiently. Thus Sony’s rule shelters VCRs, typewriters, tape recorders, photocopiers, computers, cassette players, compact disc burners, digital video recorders, MP3 players, Internet search engines, and peer-to-peer software. But Sony’s rule does not shelter descramblers, even if one could theoretically use a descrambler in a noninfringing way. 464
