Monopoly's Multiple
Intellectual Properties

The popular board game Monopoly has a patent, trademarks, and copyrights associated with it. The U.S. utility patent 2,026,082 issued in 1935 has passed into the public domain. Hence, there are many regional- and specialty-opoly games now available by various sources.

The registered trademarks are still alive along with the copyrighted game rules and other related works. See Intellectual Properties game idea for related class activity.
