Also in the 1970s, Professor Ralph Anspach, who had himself published a board game intended to illustrate the principles of both monopolies and trust busting, fought Parker Brothers and its then parent company, General Mills, over the copyright and trademarks of the Monopoly board game. Through the research of Anspach and others, much of the early history of the game was "rediscovered" and entered into official United States court records. Because of the lengthy court process, including appeals, the legal status of Parker Brothers' copyright and trademarks on the game was not settled until 1985.
