===1970s–1980s===
Economics professor [[Ralph Anspach]] published ''[[Anti-Monopoly]]'' in 1973, and was sued for [[trademark infringement]] by Parker Brothers in 1974. The case went to trial in 1976. Anspach won on appeals in 1979, as the [[United States Court of Appeals for the 9th Circuit|9th Circuit Court]] determined that the trademark ''Monopoly'' was [[generic trademark|generic]] and therefore unenforceable.<ref name="auto">{{Cite news |date=October 20, 2009 |title=How a Fight Over a Board Game Monopolized an Economist's Life |work=[[The Wall Street Journal]] |url=https://www.wsj.com/articles/SB125599860004295449}}</ref> The [[United States Supreme Court]] declined to hear the case, allowing the appellate court ruling to stand.

However, ''Anti-Monopoly'' was exempted from the law and Anspach later reached a settlement with Hasbro and marketed his game under license from them.<ref name="anti-wsj" />
