Summary

Portrait of John Paul Stevens 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.
