Sappho Sextet

Under the 1976 Copyright Act, works published between January 1, 1978, and February 28, 1989, were required to be published with a valid copyright notice or be registered within five years to maintain copyright protection. A thorough search of the US Copyright Office's online database (which covers all registrations from 1978 to the present) yields no results for the title 'Sappho Sextet' or variations thereof. The film was released by International Home Entertainment, a low-budget independent distributor. If the film was distributed without a valid copyright notice on the release prints and no registration was filed within the five-year cure period, it entered the public domain under 17 USC §405. However, since the presence or absence of a notice on the original physical prints cannot be verified without inspection, and the Copyright Office record is silent, the status is technically uncertain. However, the lack of a registration for a 1983 US production strongly suggests a failure to comply with the formalities of the 1976 Act.
