Actually, it's not cruel. Although his language is abusive, his intention has some merit.
Studies by the National Science Foundation and others have shown that a disproportionate number of the really questionable patents have had the same examiners.
POPA, the Union that represents examiners, and the executives at the USPTO need to feel more pressure when it comes to correcting the mistakes of individual examiners or their managers.
RIght now, the system skews towards rewarding the examiner who approves a patent, rather than an examiner how gives final judgment against approval.
Anecdotally, it appears that some examiners are even more ready to approve patents than the rest of their colleagues, and public pressure to 'call them out' might be a useful tool for both the Union and Administration to find a resolution to a few bad, or at least misguided, apples.
It's worth noting that IBM is the largest patenter for the USPTO, and as such has incredible influence there. For all their Open Source marketing speak, they continue to pursue absurd patents and to collect royalties off of software patents.
For IBM to file for a patent like this demonstrates that either they are monumentally duplicitous in their intent with regards to method/software patents, or that they are a company where the left hand doesn't know what the right hand is doing.
