How long does copyright protection last?
What is the owner of the copyright dies.....it the work product no longer protected?
A work that was created (fixed in tangible form for the first time) on or after January 1, 1978, is automatically protected from the moment of its creation and is ordinarily given a term enduring for the author’s life plus an additional 70 years after the author’s death.
In the case of “a joint work prepared by two or more authors who did not work for hire,” the term lasts for 70 years after the last surviving author’s death. For works made for hire, and for anonymous and pseudonymous works (unless the author’s identity is revealed in Copyright Office records), the duration of copyright will be 95 years from publication or 120 years from creation, whichever is shorter.
Does it need to be renewed? Yes

Is the renewal process much different than the original application process? Or is it just a matter of paying fees for the renewal?

Thanks for the info. I appreciate it!
