So does that mean that only the prescribed "methods" for accomplishing a goal can be patented? If so, could you ever have a UI patent (such as the rubber band effect), or just patent methods to accomplish a rubber band effect? If it's just the methods, then doesn't that make it incredibly easy to work around? Or would any set of methods that accomplish the specific effect be legally equivalent to the patented method?
