Although, if I were to take your implication correctly - there should be no incentive to take a patent or reject a patent other than its merit.
Which would in turn imply no cost on applying for a patent, except its applicability after review.
But that would also create a perverse incentive for firms to submit patents all the time - there is no cost involved, no barrier of entry and hence no loss in making the effort.
Alternatively, we could have a very quick review system, which would mean that soon after patent submission you get rejection or acceptance. Which would mean that the patent office would need significantly more funding - considering the number of patents it receives vs people who have to review.
If there was a solution which could automate the search for prior art, that would be cool, and a way to reduce the size of the work load.
