If more than one person have a simila idea in a close enough time frame, similar enough to generate competing patents, it should be ruled as obvious and not patentable as too obvious
Why? Is something only non obvious if only ONE person in the world can figure it out? History is rife with two or three people racing to an invention. that doesn't mean the invention is obvious. I would think it would take more than two or three geniuses figuring something out to claim it as obvious.
