John Paul Stevens,
Eldred v. Ashcroft — Dissenting Opinion
“ Neither the purpose of encouraging new inventions nor the overriding interest in advancing progress by adding knowledge to the public domain is served by retroactively increasing the inventor’s compensation for a completed invention and frustrating the legitimate expectations of members of the public who want to make use of it in a free market. Because those twin purposes provide the only avenue for congressional action under the Copyright/Patent Clause of the Constitution, any other action is manifestly unconstitutional. ”
