I would imagine it would be hard to patent the bot since they didn't invent spidering urls...
What they do have a patent on (since they bought Applied Semantics) is a method to determine contextual relevancy. But even that method is really not designed for what it is being used for so who cares?
One more thing. I'll bet no one can tell me who started the whole keyword buying thingy and when. Anyone want to take a guess?
