The requirement of originality was also invoked in the 1999 United States District Court case "Bridgeman Art Library v. Corel Corp." In the case, Bridgeman Art Library questioned the Corel Corporation's rights to redistribute their high quality reproductions of old paintings that had already fallen into the public domain due to age, claiming that it infringed on their copyrights. The court ruled that exact or "slavish" reproductions of two-dimensional works such as paintings and photographs that were already in the public domain could not be considered original enough for protection under U.S. law, "a photograph which is no more than a copy of a work of another as exact as science and technology permits lacks originality. That is not to say that such a feat is trivial, simply not original".
