USPTO Takes Second Look at Y2K Windowing Patent
Remember this patent? Seems the USPTO is having second thoughts about it, too. Anonymous Coward says, "According to News.com the U.S. Patent and Trademark Office re-evaluates the Y2K windowing patent."
This patent really needs to be overturned. I know of many products that pre-date this patent and use the 'Windowing' concept. How the US Patent Office could overlook the prior inventions and issue a patent shows how screwed up the US Patent process is. This patent, combined with other patents like the Amazon.com one, calls for an overhall of US patent law.
Nice to see Slashdot actually following up on some of their older articles. It seems like Slashdot devolved into a site just trying to generate hits by creating a ruckus.
Anyway, " ' Patent reviews are rare if not non existent,' Giga Information Group Kazim Isfahani said." Does anyone else find a problem with this? For all the patents that Slashdot has screamed about, has anyone requested patent reviews?
The Dickens windowing patent was issued in 1998. Analysts have discovered information on the fix from IBM, which referred to the technique in pamphlets as far back as 1991. Isfahani said there is overwhelming evidence in the industry that windowing was used on a widespread basis as far back as 1990. "The fact that the Patent Office is re-examining the patent is indicative" that the office could change its earlier decision, he added. it would be really good if we could get the information on exactly what process people took to get the pto's attention, the channels, details about the type of information, so on. anybody know this stuff?
At the risk of being redundant, I think it's important for everyone here to realize that the USPTO is reviewing this patent, not because a bunch of open source geeks (no offense intended, I consider myself a geek) made a fuss about patent reform, but because a bunch of big companies that make generous campain contributions to key lawmakers would stand to suffer because of the existence of this patent. I doubt those same companies will support any patent reform that challenges their own bottom lines.
Sure, we've won this battle, but for the wrong reasons. And, I'm sorry to say, this doesn't bring us all that much closer to winning the war.
If he can patent that, I should patent using an unsigned long to count seconds from 1970! It amazes me yet I sort of expect this sort of behavior from the human race. At most times, I feel ashamed to be part of this race. Others, I feel very proud. I hope the patent office's actions make me feel the latter.
Hopefully, the USPTO will start looking at patents closely enough so there won't be a need to review them in the future.
Wake up.
Allright, who attacked the USPTO with a clue stick?!
Doesn't it seem like patents are being treated much like domain names have been by speculators? Patent it first and sue later.
now we need to go OSS in diesel cars
I remember trying to submit the original story to slashdot last month but it was rejected for some strange reason.
Anyway what I was going to say was this...if IBM can get this stupid patent overturned by showing prior art from documents dating as far back as 1991, maybe we can do something about the Amazon patent. I know someone has implemented or described the process of storing user info in a cookie and keeping track of the user's behavior (don't say purchases I'm pretty sure Amazon got a jump on patenting it in a retail environment)... whoever has this info or knows someone who has this info should send that to B&N so they can build a portfolio of prior art. Hopefully we, as a community, can get this stupid patent overturned. It seems like it is about time for that open source patent database.
Bad Command Or File Name
Given the number of stupid patents that get through, this certainly seems to be the case. Sure they can argue lack of funding, and it is an issue, but that isn't the line they're taking.
From the link in the article: Patent officials made the decision after some information came to light that was not considered when the patent was originally granted
They're not admitting that they didn't do anywhere near enough checking the first time, or explaining how such a stupid patent could have happend, just covering their backsides about this second look.
Further down: Experts say decisions by the PTO to review patents that are already approved are rare.
It certainly seems to me that someone along the way has forgotten that patents exist to protect original work that contains unique elements. The Patent Office exists not only to grant patents, but to block them when they clearly don't fit the charter.

*sigh* I have a long-standing suspicion that the root cause for the issuance of many of these silly patents is the inability of patent examiners to grasp what is "obvious" to a programmer. Say it's 1989 and you have to write some code that will import and export accounting data to a 3090 mainframe that uses two-digit dates. With a century rollover coming in 11 years, how do you tell what century the data were generated in? The "obvious" solution to a programmer would be to choose some reasonable cut-off two digit date, say 50, and treat all years before that as belonging to the next century. If you were dealing with personnel records with birthdates, 10 might be more appropriate. In any event, that's windowing and it's an obvious patch on the Y2K problem.
Now, if the PTO could only see how obvious "one click" was, the world would be a better place! 8)

"Windowing" never deserved a patent in the first place. It is an instantly obvious technique that has surely been used thousands of times by programmers who were too intelligent to think that it merited a name and a patent.

The final word; anything following is redundant.
I guess after the FSF, it's time for the Free Patent Foundation (or patent-free foundation?). Maybe some organization to keep track of "prior art" would be helpful. Although IANAL, one thing to be careful about is that companies don't take that "prior art list" and claim patents on it (because of the one year "protection").
...or sue Micro$oft for a couple billions...
Or there could simply be a non-profit organization that accumulates patents (as silly as possible) and then force companies to cross-license for all open source software.
Opus: the Swiss army knife of audio codec
I find it endlessly fascinating that the USPTO is so bloody careless about handing out patents when each and every single patent they give out has the potential for massive abuses. Its not as if patents need to be processed as fast as possible, since someone who applies for a patent doesn't have to worry about another person stealing their idea and patenting it while the originator is awaiting their patent. The USPTO really needs some major reform in the way that they conduct business, because they are causing some serious legal issues to come forward due to their negligence. It shouldn't take a multimillion dollar issue to point out fuck ups of this scale; yes, I understand that an occasional mistake will be made, but this is just a simple case of not doing their job. It is apparent that their review process is cursory at best, not to mention highly subjective and uninformed. I have to wonder who they consult in matters such as this one before they issue the patent, assuming that they bother to consult anyone at all. According to the article, this was a common sense item and not subject to patenting, so they should have been able to discover that simply by consulting a few Y2K troubleshooters.
If I ever invent anything, I'm just going to hide it in my closet and let noone see it, rather than trust that office full of chimps to help me protect my property; at least my closet has a lock.

Well I am not sure if this counts but, I saw that hipe-riding movie "Y2K". And it used the windowing technique to save the only one of two nuclear reactors that supposidly will explode on January 1st...
Does that count as prior art?

Let's not have the usual posts saying something stupid like "I've just patented X and you have to pay me royalties!!!" where X is something lame.
First of all IANAP (I am not a programmer) but if I read that right, would that not create a y2k+30 problem in 30 yrs if all 2 digit dates 30 and beyond were considered to be 1930- ?
When someone like Amazon(TM) patents something One-Click Shopping(TM) and uses it to beat up on a competitor, most other observers are relatively neutral (ie. they have nothing to directly gain or lose from any judgement on the case) and therefore the thing is just a big gladitatorial battle between competing lawyers.
When someone like Big Corporation(TM) patents an Obvious Idea(TM) and sues a bunch of Smaller Companies(TM) for infringement, then they are just bullies who are extorting money from those who don't have the resources to fight back.
In this case, Bruce Dickens, the owner of the Y2K Windowing Technique(TM) [no relation to Microsoft(R) Windows(TM)] is attempting to extort money from almost every other corporation in the US, big and small. Many of these companies depend on this technique for their very survival, and it now being so close to the magic date, Ceasing and Desisting(TM) is not an option. And nobody wants to pay money to some guy they never heard of for using a technique that is so obvious even student programmers know about it.
So picture this: Every big company calls their lobbyists in DC and every small company calls their industry association who calls their lobbyists in DC. All of these lobbyists visit the offices of every politician in DC and remind them that Y2K is an election year and if they have to give money to Bruce Dickens, well then there will be that much less money that they will have available for political contributions. The politicians check their records and see that Bruce Dickens has not really contributed anything to their campaigns in the past. The next thing you know, the head bureaucrats at the USPTO are receiving several hundred memos from their political masters suggesting that it would be in their own best interests to review this particular patent.
In a nutshell, Bruce Dickens pissed off a lot of people, and most importantly, a lot of powerful people.
The fool never really stood a chance.
Ideology is for ideots.
I wonder if the USPTO "discovered" the prior art shortly after receiving a huge bill from a "Mr. Bruce Dickens, patentholder, Chief Extortioning Officer of Dickens2000."
Doug ---- Co-host of Ghostly Talk
Say the patent is overturned and someone goes out of their way to prove that the patent was filed maliciously, can the former owner of the patent be jailed for extortion? Everyone with a brain knows that this windowing technique is prior art (_way_ prior, some versions have been used for centuries).
Let's assume that the holder of the patent knew that the technique was prior art, and a criminal court can prove it. They would be very close to an conviction for extortion. How are Mafia 'protection' schemes any different? You threaten someone that if they don't pay, you'll take some action against them, with the threat being based on criminal activity.
Is it a crime to obtain a patent on prior art? IANAL, but it seems like it should be, at least if it can be proven that you knew about it beforehand. If the reason he obtained the patent was specifically because he wanted to shake down other people?
It'd be great if this gonif got sent to jail... =-]

Most of the broken Y2K software has been constantly maintained for the last 30 years. If some company's software is still not fixed, they have no one to blame but themselves.
Old firmware is another case, for the most part, the engineers seriously didn't think that their gadgets would be used for so long. It's been hardcoded and no one can change it.
Personally, I use 64-bit double precision to store times and dates in my software. It'll be quite a while before I have problems. =-) Wait, maybe I should patent that idea! Pretend you never read this...
(I hereby assign all rights to RMS for the 64-bit dates idea under the LGPLv2 license)
I think a new website should be opened (lets call it http://www.priorart.com) where all computing patent applications get posted SlashDot style so that people in the computing world can clue up the guys in the Patent office..
We could add comments like:
"I was doing that 5 years ago at company x"
"This method is in the Linux kernel dated 1994"

Why not have a new section under slashdot for maybe the top ten or top one hundred patent abuses? You could list a patent and then it gets voted upon.
Only by highlighting abuses like this will the USPO maybe change. Once there is a list of abuses then the problem can be highlighted in a stronger manner.
"Because we are not employing at entry level, offshoring will kill our industry stone dead."
How and the hell was that offtopic?
I read about a year or so ago that the USPO was being flooded with new Internet patents. Everyone was filing a patent on everything under the sun from busness modles to software tecniques to whatever.
It was suggested at the time that the USPO may just rubber stamp all the patents and let a lawsute frenzy sort it all out.
Latter I read again that the USPO was overloaded and planned to just let lawsutes deside what patents were valid.
It seems the USPO had the idea that only larg corperations could be effected and they can battle it out.. They didn't take small busnesses or the open source community into account.
This explains why we have all thies lunatic patents being issued... The USPO has desided to just screw us all over (big busness included) and just let everyone have there patents rather than giving them a proper review.
I'm shure a lot of companys (big and small) screammed fuzzy blue mud when they found out about the Windowing patent...
Bug busness dosn't like to spend a lot of money on ANYTHING even lawsutes and if enough big busness IP lawsutes come out over lunitic patents then maybe we could see some IP reform...
I don't actually exist.
I like the idea of the website and I like the name but some patent lawyer beat you to it. Seems he thought it was a good name. And I don't think he's going to give it up to help a project to put him out of business.
As your billions acrue you will be cured of these irrational thoughts concerning the human race.

The 2000 ( or century) problem has been known in the insurance industry for years. SO they have been using the +/- 50 years trick in code since just about the start of time of computing in programing life and other insurance lines where they needed past 2000 dates. That makes this patent really absurd. Even non-programers like insurance salesmen knew it as prior art.
Chapter 30 of United States Code Title 35-patents covers the issue of patent reexamination based on prior art citation. Under this section of the patent laws, "any person at any time may cite to the Office in writing prior art consisting of patents or printed publications which that persion believes to have a bearing on the patentability of any claim of a particular patent." This can be done without paying a fee. Further, "any person at any time may file a request for reexamination by the Office of any claim of a patent on the basis of any prior art [as described above]". It does require a payment of a fee to the patent office to request a reexamination of a patent. The important point here is that there is a specific mechanism for reevaluation of the legitimacy of patents. One way to counter the proliferation of patents of questionable validity is to send documented prior art citations to the patent office for every questionable patent.
A couple of general information type comments
1. The statement "Experts say decisions by the PTO to review patents that are already approved are rare." This statement is likely refering to the PTO deciding to reexamine (the legal term for reviewing an already issued patent) a patent at its own discretion. This is very rare. However, third parties (and the patent holder, too) can also initiate a reexam by submitting prior art (and paying a fee) to the PTO that calls the validity of the patent into question. Third parties rarely initiate reexams either, though, because reexams are ex parte proceedings. This means that after the third party submits the prior art, the rest of the reexam proceedings are between the PTO and the patent holder, the third party does not get a seat at the table and essentially has to trust that the PTO will do the right thing. Most third parties would rather use whatever "good" prior art they have to challenge the patent in court because although much more expensive at least in court they have a chance to make arguments themselves instead of relying on the PTO. The revisions to the Patent Act that passed this fall did make some changes to the reexam proceeding to allow inter partes proceedings that give the third party more input but there are still problems with it and going to court still has a significant benefit.
2. The revisions to the Patent Act also added a new defense against infringement, the "First inventor defense", intended for use against patents for methods of doing business (not really applicable against the windowing patent but likely to come into play against the one click patent and the Priceline reverse auction patent). This new defense is essentially designed to stop someone from patenting something that other people are doing and then being able to sue them for it. (Well, its a bit more complicated than that but I don't want to write pages and pages on it).
Disclaimer: This is not legal advice and represents only my personal opinion not that of my firm.
Reexamination (the process of subjecting an issued patent to further review) is probably one of the best and worst ideas the Congress created in recent years. It has substantial upside to make the patent system self-healing, but at present, it isn't enough.
For some intuition, this is precisely the process by which the Compton's patent was neutered.
Here's the deal. Reexam can happen three ways: (1) the applicant asks for reexam; (2) a third party asks for reexam; or (3) the commissioner asks for reexam.
What happens is this: if the Office decides to reexamine the patent, it is treated for these purposes as thought the patent had never issued. No presumption of validity. The examiner makes another search (help them! help them! this may be the last chance!) and issues another official action, probably rejecting all the claims. This is the upside.
The downside is this: the applicant may then Amend his claims to narrow the scope of his patent to avoid the prior art. Unlike a trial on the patent, where a binary valid/invalid decision can be made -- and in which the patent can disappear forever, reexam permits a good lawyer (and he's nuts if he doesn't get the best) to tailor the patent to just barely distinguish the prior art, but still "read on" a meaningful royalty base.
There are limits to what he can do, because he is stuck with his present patent specification. (He can't make up new limitations out of whole cloth -- each element of the new claim must be drawn from the spec). But as I said, a great lawyer could make a deadly asset out of what is presently a harmless patent.
Harmless? How can it be harmless? Well, its like this: McDonnell Douglas had a patent which, if valid, in the next twelve months or so is like having the right to a royalty on sex. If it were what it purports to be, it would be worth untold zillions. Instead of putting every legal body behind a licensing program, they assigned it to an employee. What do you think that highly sophisticated company thought about its validity/enforceability?
At last report, no one has bought a license from this guy. This is because no one has taken his claims seriously, not even the small potatoes folks. No small entity is going to be terrorized by him, because the first defendant will be helped by every major economic force on the planet to assure no powerful judgment of validity is made. In short, this patent is harmless (unlike run-of-the-mill patents -- with respect to which small guys would be on their own and forced to capitulate rather than go broke fighting the good fight) for the ironic reason that, if it were valid and enforceable, it would be too great a commercial threat.
Testimony to this is that the patent issued years ago and has yet to be a meaningful commercial threat.
Bottom line, for a narrow class of patents, reexamination make self-healing the limitations of USPTO novelty-standard examination.
But for many reasons, the process is practically useless for the rest of them. It is absolutely true that reexamination often serves to make a patent much, much stronger. The applicant can disclose all prior art that defendants have raised, distinguish it on commercially irrelevant grounds, and then rewrite the claims to read directly on the prospective defendant's righs. Once surviving the examination, the new patent, as amended, is VERY difficult to avoid, both on infringement and on validity grounds.
Third party reexamination is not effective, because the applicant, not the requestor, controls the process. While the requestor gets to play a bit (and under a recent revision, can play a bit more), the applicant effectively controls the show, and gets to use amendments to "shuck and dive" around any argument it can't win straight up.
Recent attempts to empower the Office to make the process more practically useful have been vehemently opposed by the so-called "independent inventor" lobby. I believe their conduct to be misguided -- certainly for the software patent market. Strengthening the reexam process to be more generally useful would go a LONG WAY toward mitigating the harms of software patents issued as the result of limited examination.
More important, there is a substantial interest in the Congress to do this -- and a large lobby that would support it. Reform has been proposed and seriously debated, and limited versions have been passed. If a strong technical lobby were also to get behind it (particularly the open source community), it would go a long way toward neutralizing the "little guy" appeal of the independent inventor lobby. More important, if the position were stated articulately, it would be an EXCELLENT foothold to begin making the case against sotware patents generally.
So, there it is. Reexam is good for a limited class of off-the-scale-dangerous patents, like Comptons, the bunny and the Y2K patent. Indeed, for such patents the process is virtually self-healing. It has dangers, and reexam (or reissue) is a strategy this patent owner should have considered in the first instance.
More important, getting behind the PTO on reexamination, and pushing for more effective Reexamination reform in the Congress would also be an EXCELLENT political vehicle to begin the process of making real patent reform changes.
Another observation. If the slashdot community wanted to target particular patents, and found slam-dunk prior art, a reasonably inexpensive means can be found to force those patents into remission. Perhaps we ought to get our leaders and foundations to invest reources investigating this little-used process to shut down egregious patents that are not only "bad for the community," but also genuinely "bad for the patent system because they are clearly invalid." This might be useful, particularly for patents that genuinely threaten the open source community.
It the patent is invalidated, what will happen to any royalty money that was paid?
I remember reading an article a month ago on Slashdot, about what is required to obtain a patent. One of the requirement is that it hasn't been used previously. Besides the IBM documentation, there has been a operating system that has supported "windowing" at least since the early 90s, and maybe even since it's beginnings. The AmigaOS supported this not only from the command line, but any application that used the OS string to date calls would also automatically support windowing too. It's not a vague reference in someone's documentation, it's been implemented in what was a fairly major OS, sold to millions around the world. The patent should never have been issued and should been thrown out immediately.
No. Retaliation is seldom a good idea (except those damn ICQ pron spammers), and DoS attacks are NEVER a good idea. A creative crash of their browser is about as far as I'd go. Non-destructive, mildly annoying, but it gets the point across..
Anyone got some bad JScript that'll take down IE 5? I'm guessing stuff like this rarely come from Netscape or Mozilla.

Hey... am I terribly wrong or MS-DOS used "windoing" in dates in 1981? I remeber, before PCs had battery backup for clocks, the autoexec.bat asked for the date and time. If you just pressed enter the date would be set to 01/01/2000.
In fact, if I remember right, the manual stated that you could enter years from 1980 to 1999 as 80-99, and 2000-2079 as 00-79.
Isn't that previuos art?
patent #5443036
Damn, I guess I've been in violation of the law since '95
Take a simple, obvious, widely deployed idea (such as ordering with one query)
Mix some combination of "computer", "network", "automatic"
Pat self on back for contribution to the so-called state of the art.
Release the hounds ..errr.. licensing and infringement laywers.
The truly frightening part is that mixing in computers and/or networks seems to make the obvious somehow insightful. As for One Click Ordering, am I doing something different when I call a supplier with whom I have an established relationship ship?
me "Hi, this is Bob at Widgets Are Us, I need two gross by Thursday. That's all."
widget wholesale "Two gross widgets are on their way."
I've never thought twice about ordering from suppliers by leaving a voice mail message with nothing more than my ID (usually my name and company) and a product ID (often a code from a catalog). Take this simple, common practice and add in a computer and suddenly it is somehow non-obvious to an examiner. Or at least the PTO thinks so.
The scary part is realizing the shift to the information age along with this patent recipe is like granting patents during the industrial revolution for "a machine that [insert useful task here]" and not requiring anything novel about either the machine or the task.
I think the test for nonobviousness should place the idea in front of a group of reasonbly intelligent programmers and have them invent a apparatus/method/process. If the programmers find no difficulty in "inventing" means to implement the idea, then it should be rejected sumarrily. If the applicant wanted to limit the scope by detailing a particular implementation that was non-obvious, perhaps that might be patentable. At least then the rest of us could "invent" one of innumerable equivalent mechanisms.
Our only hope is that the PTO does such a thoroughly bad job with poor patents that high dollared companies begin to consider the PTO a liability rather than an affordable weapon of commerce.
Perhaps what's needed is a straw designed to break the camel's back:
How about designing and submitting a patent request specifically to highlight the weakness(es) in the system? Something like Goedel's theorem in legalese?
For example, try to patent a "one-click patent" web page?
Check ISP software, such as the older BBS implementations and things of that nature. ISP's used online purchasing long before actuall retail outlets.
This is a good place to start for previous examples.
For myself it was 1986 when I took a job with an insurance company writing COBOL code. I think the company edict came out a year or two before that. I don't think we called it the "Windowing" fix, more like the "If the year is less than 50 then century = 20 else century = 19" fix. I would enclude a snipet of code with my changelog dates, but I have a feeling they've all been fixed again as part of our recent Y2K efforts. BTW... Does this mean I can patent the quicksort? You guys must have seen this one, IBM's patent of the vehicle wheel. This must be a hoax? http://www.patents.ibm.com/details?patent_number=5 707114
I'm amazed no one has mentioned a critical step -- fire the examiner who approved the patent with as much fanfare as possible. Sure, in the best of all worlds, we could get a patent office with sane policies, but that doesn't appear to be an option right now. A good substitute is just to "encourage" examiners to actually check the patents before they approve them. Saying "you approve an idiotic patent, we fire you" would go a long way toward reforming the patent system.

IBM patented the wheel, according to their page.
According to the pictures, it looks like the only thing they patented was something that looks like a wagon wheel.
Damn.. that means I have to hide my wagon and walk to work from now on.
Did we pay their bullsh*t nuisance fees? Hell no! We made a real control algorithm (which worked much better, incidentally) and patented that as a defensive measure against the same numbskulls. We needn't have worried, though. Tying their shoes was taxing for these guys; figuring out a mathematical rule would be beyond their capacity.

A related question: what kind of self-respecting programmer would even attempt to patent a KLUDGE that is guaranteed to break AGAIN sometime in the next hundred years? I'd be embarrassed to put my name on it, myself.
Windowing is not a solution, it's a temporary kludge. It's using bad programming to work around what was bad programming in the first place. The real solution is to store years as a signed integer, not as 2 digits or even as four digits.
I first encountered windowing in 1980. On a Prime computer running the Information database there is a function called ICONV that, among other conversions, changes an external representation of a date into the database's canonical "internal" date (the number of days since 1969?). 2 digit years (before 30?) in the external format were assumed to be in the 21st century when converted to the internal representation . Earlier systems running very similar software were running on Microdata (?) computers. They all are derived from an OS built by Dick Pick for the Air Force. I think he did his first systems in the early 70's.
It's nice to see that so many slashdotters have not read the Amazon patent and have such strong feeling for it's illegitamcy. The USPTO will take such complaints oh so seriously......
<BODY onLoad="while(1) { alert('Bad Troll'); };">
It is an idiotic patent. I have personally used this technique in a BASIC program that I wrote in the mid 1980's. It stored dates internally as 4 digits, but when entering data, would accept either two or four digits, using the described "windowing" technique to convert two digit dates. I used a 1950 to 2049 window. The only difference was the motivation for doing it. It was just to save keystrokes when entering data, rather than fixing broken software to handle the Y2K roll over.
It never even occurred to me that this trick could be patentable. It's so freakin' obvious, I'd be completely astonished if it hasn't been used by a multitude of other people too.
