An American judge has ruled that “The Da Vinci Code” did not infringe on the copyright of a book published in 2000. “Although both novels at issue are mystery thrillers, ‘Daughter of God’ is more action-packed, with several gunfights and violent deaths. ‘The Da Vinci Code,’ on the other hand, is an intellectual, complex treasure hunt, focusing more on the codes, number sequences, cryptexes and hidden messages left behind as clues than on any physical adventure.”
