The main issue concerning copyright law and public domain is the term (length) of the copyrights. You lose ownership to copyrights after a period of time, and the work gets transferred to the public domain. Once it’s in the public domain, anyone can use it and profit from it without the need to obtain permission. Here are the basic copyright terms you should know about:
- Unpublished works (life of author plus 70 years)
- Unpublished anonymous and pseudonymous works (120 years from date of creation)
- Works made for hire (as part of a job-120 years from date of creation or 95 years from first publication)
- Works when the death date of the author is not known (120 years from date of creation or 95 years from first publication)
Here’s an easier way to check whether the work you have in mind is in the public domain, based on when it was published:
- Works published by the U.S. Federal Government (always in the public domain, no matter when it’s created)
- Works published in the U.S. before 1923 (in the public domain)
- Works published in the U.S. from 1923 through 1963 (in the public domain, unless it was renewed during the 28th year following creation)
- Works published in the U.S. from 1964 through 1977 (not in the public domain – 95 year term applies)
- Works published in 1978 or later (not in the public domain)
Now that you know the rules, you should put your entrepreneurial hat on and think of the ways that you can make a living thanks to copyright law and public domain rules.
