Invisible Ink

Under the current United States copyright laws, specifically the 1998 Copyright Term Extension Act, all works published or registered before January 1, 1928, have entered the public domain. 'Invisible Ink' (1921) is a short comedy film produced by Hal Roach and released through Pathé Exchange. Because the film was released in 1921, its maximum statutory copyright protection was 75 years from publication (under the 1976 Act) or 95 years (under the 1998 revision). Regardless of whether it was renewed by the studio or subsequent rights holders, the 95-year term for 1921 works expired on December 31, 2016. As of January 1, 2017, the film transitioned into the public domain in the United States.
