This document discusses advanced copyright concepts related to joint works, works for hire, copyright duration, and digital performance rights. Some key points:
- For joint works created by multiple authors, each author owns a share of the entire work and either author can issue non-exclusive licenses as long as they pay the other authors.
- Works made for hire transfer full copyright ownership to the employer or commissioner of the work. Songwriters' songs are generally not considered works for hire.
- Copyright duration was extended in 1978 to the life of the author plus 50 years and pre-1978 works received an additional 20 years of protection.
- Authors have a right of termination to regain ownership of copyrights 35 years after
