Patent
A patent was granted to Wizards of the Coast in 1997 for "a novel method of game play and game components that in one embodiment are in the form of trading cards" that includes claims covering games whose rules include many of Magic's elements in combination, including concepts such as changing orientation of a game component to indicate use (referred to in the Magic and Vampire: The Eternal Struggle rules as "tapping") and constructing a deck by selecting cards from a larger pool. The patent has aroused criticism from some observers, who believe some of its claims to be invalid.
In 2003, the patent was an element of a larger legal dispute between Wizards of the Coast and Nintendo, regarding trade secrets related to Nintendo's Pokémon Trading Card Game. The legal action was settled out of court, and its terms were not disclosed.
