If I look at the WO and EP equivalent I always wonder why the US patent system is so stupid. Everything is granted. No search for novelty whatso ever. If you read the opinion of the European Patent office, these guys will have a hard time getting it granted in Europe.
Look at this document:
I see at least 5 references to article 54(1) which says: "this is not new!!!"
The only people getting rich of this type of behaviour are the laywers.
