Intellectual property (IP) laws were drafted for tangible objects, but 3D printing technology, which digitizes objects and offers manufacturing capacity to anyone, is disrupting these laws and their underlying policies. In this timely work, Lucas S. Osborn focuses on the novel issues raised for IP law by 3D printing for the major IP systems around the world. He specifically addresses how patent and design law must wrestle with protecting digital versions of inventions and policing individualized manufacturing, how trademark law must confront the dissociation of design from manufacturing, and how patent and copyright law must be reconciled when digital versions of primarily utilitarian objects are concerned. With an even hand and keen insight, Osborn offers an innovation-centered analysis of and balanced response to the disruption caused by 3D printing that should be read by nonexperts and experts alike.
