copyright act of 1909
Copyright Act of 1909. A major revision of U.S. copyright law, extending the term of protection from 14 to 28 years (renewable for a second 28-year term); measuring the copyright term from the time of publication rather than the time of registration with the Copyright Office; and expanding coverage to all writings. • The Act retained the formalities for securing a copyright and required that a copyright mark appear on the work. It governed U.S. copyrights issued from July 1, 1909 to December 31, 1977. Although the 1976 Copyright Act supplanted the 1909 Act, the 1909 Act still applies to some pre-1978 claims and affects certain other rights of copyright owners. — Also termed 1909 Copyright Act.
