Yes, but trademark protection wouldn't prevent people from using or selling the older works, at least not in general. From http://www.publicdomainsherpa.com/tr

Yes, but trademark protection wouldn't prevent people from using or selling the older works, at least not in general. From http://www.publicdomainsherpa.com/trademark.html http://www.publicdomainsherpa.com/trademark.html : > Twentieth Century Fox was the producer of a World War II video series that was no longer protected by copyright. When a competitor used it, Fox sued — not for copyright infringement (because they couldn’t), but for trademark infringment. They lost. See Dastar Corp. v. Twentieth Century Fox Film Corp. et al., 540 US 806 (2003), which you can read here: ( http://www.publicdomainsherpa.com/support-files/dastar.pdf http://www.publicdomainsherpa.com/support-files/dastar.pdf ).
