Alaska Knights

Alaska Knights (alternately listed as Alaskan Knights in some catalogs) was released in 1930 by Tiffany Productions, a 'Poverty Row' studio that folded in 1932. Under the Copyright Act of 1909, works from 1930 were protected for an initial 28-year term and required a manual renewal registration with the US Copyright Office in the 28th year to extend protection to the full 75-year (now 95-year) term. A search of the Stanford Copyright Renewal Database, the University of Pennsylvania Catalog of Copyright Entries (CCE) for the years 1957–1959, and the Film Superlist: Motion Pictures in the U.S. Public Domain (Hurst/Baer) shows no record of renewal for this title. Because the renewal was not filed during the statutory window, the copyright expired at the end of its first term in 1958. The film's public domain status is further corroborated by its frequent appearance in the catalogs of public domain specialized distributors and its availability on archive.org without copyright challenges from a successor in interest.
