Sex Kittens Go to College

The film was released in 1960 and registered for copyright by Photoplay Associates, Inc. on August 15, 1960 (LP17166). Under the U.S. Copyright Act of 1909, works from this era required a renewal filing with the U.S. Copyright Office during the 28th year of their first term to extend protection to a second term. For a 1960 release, the renewal window was open in 1987 or 1988. A search of the Stanford Copyright Renewal Database, the U. Penn Catalog of Copyright Entries (CCE), and the U.S. Copyright Office online database reveals no renewal record for this title or its registration number (LP17166). The failure to renew the copyright caused the work to expire and enter the public domain in the United States at the end of 1988. This is further corroborated by the 'Film Superlist: Motion Pictures in the U.S. Public Domain (1950-1959)' and its supplements, which identify the film as a non-renewed work. Additionally, the film is widely distributed by known public domain labels such as Alpha Video and is available on Archive.org without takedown, which is consistent with public domain status. Note: generated without live web grounding (the grounded research engine was unavailable). Verify the cited sources independently before relying on this determination.
