For a recent law firm project, I helped a client determine whether a particular piece of artwork was in the public domain.
As I explained in a one-minute how-to interview, there are a few ways in which a copyrighted work can end up in the public domain. The most common way is for the copyright to expire. In the United States, copyright has expired for all works published prior to 1923. This particular artwork was not that old so the 1923 rule was not relevant. The artwork was a pre-1978 creation so it did not fall under the current Copyright Act which provides for a copyright term equal to “the life of the author plus 70 years”
Instead, to determine public domain status, I had to determine whether the copyright owner had complied with all the formalities that used to be (but no longer) are required for maintaining one’s copyright. For that determination, I still needed the date on which the artwork had actually been published. You might consider that to be an easy question to answer but that’s not always the case.
In order for your copyrighted work to be considered published, the copyright owner must authorize the publication and multiple copies of the work must be available to the public. Putting your artwork on public display in a museum does not by itself qualify as publication because that is only one copy available for the public to view. Similarly, distributing copies of the artwork to a few close friends probably would not qualify as a publication. However, selling print reproductions of the artwork in the museum gift shop would likely qualify as a publication.
Visual artists are not alone in their confusion about publication dates. In another posting on publication dates, I discussed whether the correct publication date of a book would be the date books are printed, the date the books arrive at the warehouse, the date copies go to distributors, or the date on which the first copy is sold.
