Lifetime of the Author + 25 years ONLY IF HUMAN.
Corporations a simple 70, non-renewable.
My rationale:
For Human authors, dependents (not extended to just any heirs), The creator may not have been available to the rest of the Family, or the work impacted Family life due to deadlines and other requirements (tours...).
I chose 25, because most offspring are on their own by then. Thus less impact on THEIR lives.
Dependents should get something, as they may have been a sounding board or other contributor to the creation. But not the 'Aunt Tillies'
