Feel free to make a different comment, I’m just reproducing the ones that are made on a regular basis. I don’t judge whether they’re correct, just whether they’re frequent!
More seriously, rather than trying to only throw obvious ones out I would suggest applicants submit a bounty on each patent to be paid out when prior art is discovered. Or returned after 5 years. The patent office can then charge a small fee to compare prior art to a patent or patent application and it becomes expensive and pointless to submit most dumb patents without costing the taxpayers anything.
