Adobe Utopia was originally designed by Robert Slimbach and released commercially by Adobe Systems Incorporated in 1989. In 1992, Adobe contributed the typeface to the X Consortium for distribution with the X Window System, under a license allowing redistribution without fee. In 2006, Adobe re-licensed the Type 1 versions to the TeX Users Group under an expanded license clarifying the terms under which modified versions may be distributed, and granting the right to sub-license. TUG in turn sub-licensed all their rights to the typeface to any and all interested parties.
Note that this license applies only to the original PostScript Type 1 versions of Adobe Utopia. Adobe has since released a new commercial version of Utopia in OpenType format, to which this license does not apply.
