> In most of the law systems out there the copyright stays valid for 70=20
[I don't want to appear picky but IMO it is important to be as precise
as one could possibly be, therefor...]
That is not quite correct. At least for the german law system and
presumably for most if not all similar systems the corrrect stmts is:
In most of the law systems out there the copyright stays valid for 70=20
years (or so) after initial publication of the copyrighted work. For
work whose publication date can't be determined (*) (e.g. unpublished work)
the creators death is assumed to be the publication date for the sake
of determining the aforementioned 70 years protection period.
(*) "can't be determined" does not apply for published work with an
insecure initial publication date. In those cases the earliest documented
publication (i.e. prooveable in court) is considered the initial publication
=2Edate
Note that the original phrase could last indefinitely by simply moving
the copyright from person to person.
Best,
