opus_dei_logoThe Catholic institution Opus Dei – described with a certain amount of liberty in the book and movie of Dan Brown’s The Da Vinci Code – has sued sggc Dema Games over their card game Opus Dei: Existence After Religion, citing trademark violation.

Source, which is a press release from the publisher, claims that the name “Opus Dei” was inspired by the Latin phrase “opus dei” after reading Dan Brown’s book and believing that the organization in the book was entirely fictitious. While they  eventually discovered that the organization did in fact exist, they already had the game in production and the rights to the tradmark in Denmark.
