Namco sued Sony for copyright infringement after one of Sony BMG's recording artists (Lil' Flip) included samples from the Pac Man video game in his 'Game Over"? song. The parties recently settled out of court, although the terms of the settlement were not disclosed.
In an earlier posting , we reported about US Circuit Court of Appeals judgement which confirmed that sampling even three notes from a sound recording can violate US copyright law. This case and the Namco case reiterate the importance of doing proper copyright clearances before releasing your games. You'd hate to get caught with ghosts in your closet. Especially Pinky... he's a speedy one.
