HP Patents Bignum Implementation From 1912 144
I Don't Believe in Imaginary Property writes "The authors of GMP (the GNU Multiple Precision Arithmetic Library) were invited to join Peer-to-Patent to review HP's recent patent on a very old technique for implementing bignums because their software might infringe. Basically, HP's patent claims choosing an exponent based on processor word size. If you choose a 4-bit word size and a binary number, you end up working in hexadecimal. Or for a computer with a 16-bit word and a base-10 number, you use base 10,000 so that each digit of the base-10,000 number would fit into a single 16-bit word. The obvious problem with that is that there's plenty of prior art here. Someone who spent a few minutes Googling found that Knuth describing the idea in TAOCP Vol. 2 and other citations go back to 1912 (which implemented the same algorithm using strips of cardboard and a calculating machine). None of this can be found in the 'references cited' section. Even though the patent examiner did add a couple of references, they appear to have cited some old patents. The patent issued a few months ago was filed back in October of 2004, and collected dust at the USPTO for some 834 days."

I guess that there is some good news in this article. The patent hasn't been issued yet, it is only being reviewed right now. And this review is accomplishing what it is meant to: showing that the patent claim is ridiculous. Yeah, HP shouldn't try patenting this, and the USPTO probably should have thrown this away in November of 2004, but still it was caught and (hopefully) won't be issued. The system is working, kinda, and this patent at least will hopefully not be issued. We will only need to get out the torches and pitchforks if the USPTO grants this patent anyways despite the outcry and prior art.
WikiPatents? Good idea! (Score:4, Insightful)
I think this is the first time I've heard of WikiPatents at all, and I don't think it's been featured on the front page yet.
I'm thinking this would be very useful in the patent approval process, not just after the fact. Suppose it worked like this: The second you file a patent, it would be published. Before it could be approved, it would have to be public for some length of time, during which anyone could present prior art or arguments for "obviousness".
On the other hand, I think they're being entirely too kind. From their FAQ [wikipatents.com]:
Patent Examiners do an excellent job reviewing patents in the limited amount of time they are allotted to review patents. However, no single individual can accumulate all of the most relevant information to review a patent within 10 hours, 100 hours, or even 1,000 hours.
On the other hand, based on the "quality" of the patents which get through (like this one!), it really doesn't seem like Patent Examiners even bother to Google it before approving.

It's worse than that - this isn't something you Google, because as soon as you are able to understand what the patent is saying, you will also understand that it is obvious in an especially egregious way. The patent examiner cannot have understood the patent and still have granted it. It is much like the Russian patent on bottles a while back. If anything, NOT doing what the patent is suggesting is the non-obvious thing.

Crowd-sourcing patent review is a very good idea actually. Patent applications are normally published after 540 days [wikipedia.org] whether they've been issued or not, so putting them up for public comment *before issuance* would be in line with current policy. And since slashdotters are used to providing references, the clerks could just ignore everything else and look up the references people posted. WikiPatents.com is a start but does not seem to allow people to actually critique a patent (or application) for being unique.
Only problem is: how are we going to get an intelligent (slashdot) crowd to research all of the ~500,000 patents filed each year? For that matter, would this actually be able to deter some of the frivolous patent applications, i.e. actually have them denied? I would love to see the (probably short) list of patent applications that have been denied recently.
Patent system fundamentally broken (Score:4, Insightful)
The current patent system presumes that "everything worth inventing, that has been invented, already has a patent". That wasn't really true in the late 1700s, and is completely nonsense today.
Eben Moglen made an interesting point about patents back in 2009 [dwheeler.com]. Today, any time the government wants to create a new rule/regulation, they must normally ensure that the public can participate/review/comment on it. Also, the government must show that the benefits of the rule/regulation exceeds its costs. All of this is courtesy of the Administrative Procedure Act of 1946 (aka the APA). The APA is no garden of perfection, but it has helped. The big exception is the patent system, which predates the APA, and thus patents are exempt from the APA. In the patent system, there is no opportunity for the public to participate/review/comment on each patent, and there is no requirement to show that the benefits of granting a patent exceeds its costs. Which is weird, because patents (as government-granted monopolies) can have as wide an effect as any other rule or regulation. We need to get rid of software and business method patents [dwheeler.com], at least, but changing the patent system to require public review and a demonstration that costs exceeded benefits would help too.

The whole idea is not that the patent has any basis but that it is ridiculously expensive to go to court. This puts a huge entry barrier around the market and protects the large incumbents. In essence, patents are now being used to protect large corporations from small entrepreneurs - exactly the opposite of their original intention.

Errm, patents are supposed to be usable by someone skilled in the art to produce the invention; no? If the patent examiner can't understand what the patent is about then either:
or both. In the case of (b), the patent should be instantly rejected as it doesn't fulfil the criteria of disclosing details for a limited monopoly,
In the case of (a) the examiner should refer to someone who is [so skilled] to give guidance and to fail to do so is negligence (and so either personally or the USPTO should be liable for costs incurred in defending against such a patent when the patent is shown to be issued wrongly).

Your comment directly says his post was not long enough, so to discard the requested length below is a red herring.
No, it doesn't. It says he should have provided some references for his three stories. It's possible to provide references in a short, concise way. You don't do that either, making your post unnecessarily teduous to read.
Section B - Poster's comment #2.
"2. Aspirin was patented well after a similar process for making Salicylic Acid on an industrial scale was. The office decided, with no precidents, that making the same chemical in pure enough form that it was safe for medicinal use was novel. When challenged on it, the USPO said they were going through a bottle a day deciding patent claims and were not about to reject rewarding this claim no matter what the law said."
Your discussion on the chemistry, production and product history of aspirin is very lengthy, but does not constitute a substantial reference either for or against the GP's claim. It says nothing about the patent status of different *production methods*, only that they were different, which in my eyes seems to at least undermine the GP's argument. The rest is basically just a long list of links and pieces of text about aspirin that adds little to the discussion of patent practice at the USPTO, in addition to being largely orthogonal to either the parent or grandparent poster's statements. Also you mingle patents and trademarks in the discussion, which is careless and misleading at best.
In the spirit of Karl Popper's criticism of what he calls the Neo-Dialecticians (the reference for which you can find on Google) you may add a few items to your signature, such as variations of "Cx, Drowns Fellow Human Beings in a Sea of Words, with x one of "1: Correct", "2: Wrong", and "3, Irrelevant to the Subject". Your post looks like a case of C3.
