 The case was then appealed by General Mills/Parker Brothers to the United States Supreme Court, which decided not to hear the case in February 1983, and denied a petition for rehearing in April.This allowed the appeals court's decision to stand and further allowed Anspach to resume publication of his game.With the trademark nullified, the name "Monopoly" entered the public domain, where the naming of games was concerned, and a profusion of non-Parker-Brothers variants were published.
