- Key Productions, Inc
- Class
- MP — published motion picture other than a photoplay (numbering series begun Jan. 1950)
- Finding
- no renewal entry found for 1977-1979 in the CCE motion-picture renewal sections or in the Copyright Office renewal records 1978-2025
- In the public domain since
- 1 January 1979 (end of the 28th year, no renewal)
An automated finding, not a verdict. A renewal would have appeared in the Copyright Office's renewal registrations 27 to 29 years after the term began. Those volumes are loaded and our parse of them found no matching renewal. If that is right, a work published 1931–1963 that was not renewed entered the public domain at the end of its 28th year; the volumes are OCR of old print, and the method page reports how often the parse has been found to miss one.
A renewal had to be filed in the 28th year and would be listed in the 1977 or 1978 volume; volumes searched: 1977, 1978, 1979.
