This copyright term of the author’s life plus fifty years put the U.S. in conformance with global standards under the Berne Convention  and the World Trade Organization (hereinafter “WTO”)’s Agreement on Trade Related Aspects of Intellectual Property Rights  (hereinafter “TRIPS”).
In 1993, however, a European Union directive extended the copyright term to the author’s life plus seventy years.  The United States followed suit in 1998 with the Sonny Bono Copyright Term Extension Act, which, like the E.U. directive, extended the copyright term for an individual’s works by twenty years, resulting in a term of the author’s life plus seventy years.  It also extended the term for anonymous, pseudonymous, or works made for hire by twenty years, resulting in a term of ninety-five years from publication or 120 years from creation, whichever comes first.  The CTEA also applied retroactively, extending the term of existing copyrights. 
This retroactive extension of the terms of existing copyrights was challenged in Eldred v.
