That's pretty much the position that I've come to concerning copyright. Individual works last 20 years or until the first author's death, whichever is greater.

That's pretty much the position that I've come to concerning copyright. Individual works last 20 years or until the first author's death, whichever is greater. The rights are assignable but non-transferable. Corporate works last 20 years. The rights are transferable. Then patents, NDAs, and non-competes are a whole other issue to resolve.
