Hello,

Since in CA and EU, copyright is life + 50/70 years, what is the protection
of copyright on something created by a corporation?
For example, Waxman's Carmen fantasy - the Piano accompaniment is copyrighted in 1947 by HARMS inc.
How long is that protected for in CA and EU?

Still Life + 50/70 years after the death of the author.

Simple in France: 70 years after publishing https://fr.wikipedia.org/wiki/%C5%92uvre_collective but complicated elsewhere: https://en.wikipedia.org/wiki/Collective_work 70 years after the death of the last surviving author if he can be identified.
