"Quadratic time factorization" patent
 

Has anyone come across the following US patent application made by Sherwin Han?

[url]http://patents.justia.com/patent/20140207839[/url]

It makes very bold claims but appears to be nonsense (quite apart from being full of typos, inconsistencies and ambiguities).

The method detailed doesn't work, as far as I can see.

The guy has had a couple of IEEE papers published ([url]http://dblp.uni-trier.de/pers/hd/h/Han:Sherwin[/url]), so perhaps not a crackpot; is this a speculative patent maybe?

Interested in anyone's thoughts.

(1) It is complete nonsense. It is word salad.
(2) The patent office does not grant patents to ALGORITHMS.

If this crank wants to spend thousands of dollars patenting something that is complete nonsense, let him.

I can't imagine what might be gained from such a patent.

His so-called papers appear to be total nonsense as well. (just from their titles)

Good - not just me then :)

He seems to be a first class crank!!! See:

They all appear to be complete nonsense.
