According to the poster on
this website the United States will greatly expand the amount of "orphaned works of art".
from the article:
"An Orphaned Work is any creative work of art where the artist or copyright owner has released their copyright, whether on purpose, by passage of time, or by lack of proper registration. In the same way that an orphaned child loses the protection of his or her parents, your creative work can become an orphan for others to use without your permission."
"If the Orphan Works legislation passes, you and I and all creatives will lose virtually all the rights to not only our future work but to everything we've created over the past 34 years, unless we register it with the new, untested and privately run (by the friends and cronies of the U.S. government) registries. Even then, there is no guarantee that someone wishing to steal your personal creations won't successfully call your work an orphan work, and then legally use it for free."
Bill Gates apparently owns one of the companies that would handle the registrations....
