Assault on Precinct 13

Under the Copyright Act of 1976 and the Copyright Renewal Act of 1992, works published between 1964 and 1977 inclusive were granted an automatic renewal term of 67 years, for a total of 95 years of protection from the date of publication. For a US film from 1976 to enter the public domain, it would have to have been published without a valid copyright notice. Assault on Precinct 13 was registered with the U.S. Copyright Office by CKK Corp. on November 1, 1976 (PA0000001091). The film is currently actively managed and commercially exploited by rights holders (licensed by Shout! Factory and Image Entertainment for recent high-definition restorations), which serves as strong evidence of a valid and maintained copyright chain. As the film was registered during the 1964–1977 window, it did not require a manual renewal filing to remain protected.
