People keep saying Demon's Soul - but, as Galaki said, similar is not the same as.. same. Was Demon's Soul an MMO? As far as I know, it wasn't.
The idea of such a game sounds great to me, imo most of the advantages of MMO, but without the PK part. Note that this isn't entirely single player, part of the patent is that you can play with whoever is your friend.
That said, I don't think any company should get a patent for any type of game.
