This Article aims to examine whether, as some courts indicate, the Sony doctrine is largely irrelevant in cyberspace. If the answer is no, how should courts properly apply the Sony doctrine to protect copyright holders' legitimate interests and further the innovation and prosperity of Internet technologies? This Article argues that the Sony doctrine should be given the widest application possible and not be subject to any preconceived formula. In the digital age, the test of "capable of substantial noninfringing uses" is still well suited to advance the ultimate objective of copyright law contemplated by the Supreme Court as well as by the Constitution: "promot[ing] the Progress of Science and useful Arts."
