Re Patents (Just get rid of them entirely!) Please prove me wrong that they aren't effective and are a myth. Processes of how to do things often come down to engineering and math; if given the same goal a solution is likely to be similar at it's core as for any given problem there is probably an ideal bound and variations of effort will produce similar results or results optimized slightly to different circumstances.
