United Kingdom The
Copyright Act 1775 established a type of perpetual copyright which allowed "the Two Universities in England, the Four Universities in Scotland, and the several colleges of
Eton,
Westminster, and
Winchester to hold in Perpetuity their Copy Right in Books given to or bequeathed to the said Universities and Colleges for the advancement of useful learning and other purposes of education." All provisions granting copyright in perpetuity were abolished by the Copyright, Designs and Patents Act 1988, but under transitional arrangements these rights do not fully expire until 2039. Separately, the Crown retains rights under the
royal prerogative to control printing of the
Authorised Version of the Bible, and of the
Book of Common Prayer.
J. M. Barrie's 1904 play
Peter Pan, although out of copyright, is covered by special legislation which grants
Great Ormond Street Hospital a right to royalties in perpetuity. Specifically, the
Copyright, Designs and Patents Act 1988 provides that the hospital trustees are entitled to a royalty "in respect of any public performance, commercial publication or communication to the public of the whole or any substantial part of [the play] or an adaptation of it." This law does not apply to earlier works which feature the Peter Pan character, such as
The Little White Bird and
Peter Pan in Kensington Gardens.
United States In the
United States, perpetual copyright is prohibited by its
Constitution, which provides that copyright is "for limited times". It does not specify the length of the term, nor does it impose any restriction on the number of times the term may be extended. Since the enactment of the
Copyright Act of 1790, copyright term has been extended by
Congress on four occasions, retroactively extending the terms of any copyrights still in force. Following the enactment of the
Copyright Term Extension Act in 1998, a coalition of plaintiffs led by publisher
Eric Eldred argued that this act and a
previous extension of the copyright term in the 1970s had created a
de facto "perpetual copyright on the installment plan". This argument was rejected by the
US Supreme Court in
Eldred v. Ashcroft, which held that there was no limit to how many times the term of copyright may be extended by Congress, so long as it is still a limited term at the time of each extension.
State and
common law had granted perpetual copyright in certain special cases not covered by federal copyright law. Sound recordings made before 1972 were under the jurisdiction of state copyright laws. which provided perpetual, common-law protection; these laws were pre-empted by the Hatch–Goodlatte Act. Prior to 1 January 1978, when the
Copyright Act of 1976 came into effect,
unpublished works were protected by common law, which recognized perpetual copyright in these works for as long as they remained unpublished. The 1976 Copyright Act exerted federal jurisdiction over unpublished works for the first time and all copyrights in these works were assigned a fixed term even if they remain unpublished. In the case
Golan v. Holder (2012), the Supreme Court ruled that Congress could release works from the public domain to submit them again to the protection of copyright, without violating the Constitution.
