America Invents Act, business methods and software patents

You may know that America has a new legislation regarding patents, the [ America Invents Act]. An remarkable part of it is sec 18. "TRANSITIONAL PROGRAM FOR COVERED BUSINESS-METHOD PATENTS". My understanding is that, in short, this is the result of banks lobbying after having been sued for business methods infringement, for some (trivial, wide-ranging) methods they used to create their products. Funny thing some particular interests managed to have their (very specialized) point of view makes a particular provision in law. Anyway, what they say in clear is that patents for ''their'' business methods are bad for their business. Wouldn't be the simple thing to follow the European path and declares that software and business methods are not patentable ? On [ GameTime IP].
