Xerox Patent Ruled Invalid, palmOne Exonerated

An anonymous reader writes "palmOne has issued a press release, that a court has found that the patent that Xerox was using to sue Palm for its character entry method, and was developed in house, didn't infringe because the patent was invalid." The case was first brought against 3Com Corporation back in 1997 before they spun off the Palm brand name.

      My theory is that this sort of thing tends to happen with large companies that have research divisions. (A notable exception is AT&T which I'll get back to in a bit.) My theory as to why this happens is that management either doesn't "get it" for a lot of the things developed, or is too afraid to take action.

      For the "failure to 'get it'" part, they fail to see how many inventions, as novel as they may be, will be a success in the marketplace. Management in large companies tends to be very short-sighted and often bad predictors of where the market will go.

      For the "too afraid" part, a lot of managers like to keep the status quo because it means low-risk both for the company as a whole and the own careers. No manager wants to sign off on a new product only to have it fail miserably in the market.

      There needs to be a few managers with both vision and guts. If they either sufficiently high-up in the company or have enough convincing power, new products come to market. Sometimes what happens, however, is that they get disgusted with their company's inaction and quit to form start-ups.

      As for AT&T, the reason they've been an exception is because, back in the good old days before divestiture, their research division was focused on doing pure research without any concern for bringing their research to market. They patented lots of things. Indeed, the Bell Labs motto was, "A patent a day," and it was pretty much accurate. However, AT&T never bothered to enforce its patents or sue anybody back then and pretty much gave away their inventions. Why? Because they viewed it as "giving something back" for being allowed to be the benevolent monopoly for the phone company. Of course once divestiture happened, all that changed.

      Unless Palm have their own patents on it, I guess so.

      The Xerox patent was on "unistrokes", a system that was _very_ similar to Graffiti, but is a little simpler to implement, faster to use, and harder to learn.

      Unistroke uses only three types of stroke, a straight line, a curve through 90 degrees and a curve that crosses back over itself, which makes the recognition much easier than graffiti. The system was designed to be quick to use: common sequences of letters alternate in direction, so that you have to reposition your pen less frequently. The drawback is that these two factors mean that a lot of the strokes are non-obvious, bearing little or no relationship to the letter they encode.

    ...here is how bad Graffiti 2 is. Why you write 't' the first stroke is an 'i'. When you make the horizontal stroke it sends a 'backspace' followed by a 't' to correct the incorrect 'i'. You can imagine how many applications are messed up by this. But it's worse: 'i' followed by a space (a horizontal stroke) is a 't'. So you have to wait between the 'i' and 'space' to make sure it doesn't come out as 't'. Please, please, pretty please, Palm bring back Graffiti 1. Graffiti 2 is like phoning people by rolling dice and pressing a button every time a digit you want comes up.

      As a stronger example, consider that Palm applications typically allow a lot of penstroke shortcuts to menu commands. You start the shortcut by writing a "/", then the associated letter. For example, the "delete" command often has a shortcut of "/d".

      Now, consider what the poster said about how the letter "t" is generated (except that the first stroke is really a "l" and not an "i"; you write an "i" by drawing an "l" and then dotting it). If your application uses "/t" as a shortcut, that shortcut cannot be written, since the menu-shortcut function accepts the first penstroke of the "t" as an "l" and processes it before you can cross the "t". No matter how fast you try to write "/t", it always gets interpreted as "/l <space>". Sucks to be you if "t" is the shortcut for "take a backup", and "l" is the shortcut for "lose this immediately".

    The program TealScript (www.tealpoint.com) lets you create any set of strokes you want, including the original Grafitti. When I originally heard about the Xerox suit, I became intrigued by the real unistroke alphabet, which is drastically and obviously different than Grafitti. See http://sandbox.parc.xerox.com/parctab/csl9501/node 4.html

    I used TealScript to create a profile that allows me to write using the Xerox unistroke alphabet. After years of use, I have become more proficient. It is indeed faster than Grafitti and much less error prone, because each character is very easily distinguishable from all other characters.

    I personally find the FITALY keyboard (www.fitaly.com) to be far faster than any handwriting recognition (5x-10x). I do have accuracy problems, but even taking the time for error correction into account, I would estimate I am 3 times faster with FITALY than with unistroke character recognition.

  19. patented invention != invention caused by patents by Adam+J.+Richter · · Score: 2, Interesting
    Uh... the transitor was patented by AT&T.

    But that doesn't show that patent incentive caused or even contributed to the invention of the transistor.

    Evidence of patent incentive contributing to the invention of the transistor might be memos from Bell Labs executives saying that they would kill the project were it not for the potential of patent royalties. (I'm not saying that that is the only form of evidence that you could find. I just want to provide an example.)

    Although I have not tracked the claims down, I've heard it said that Bell Labs's funding was largely the result of the phone company's profit being legally limited. So, if the phone company thought they were going to make too much money in a given quarter, they'd dump it into Bell Labs, which worked on things that were of potential benefit to the phone company, rather than things that were useless to the phone company but could provide substantial patent royalty revenue.

    Even if you show that the patent incentive caused or substantially contributed to the invention of the transistor, that still does not show that patents were worthwhile in this case. To do that, you have to estimate when someone else would have invented the transistor in the absence of patent incentives or with reduced patent incentives and show that the net benefit to society was probably greater with patent incentives of that magnitude.

    To go from the question of whether patents were worthwhile in this positive example to the question of what the patent law should be, you have then measure the benefits in the positive cases (if you do show that they are examples of net benefit) against the costs of the negative cases (things that are patented that would have been invented anyway, patenting of non-inventions, litigation costs, etc.).

    Obviously, this is a big empirical question. When I try to do the "math", I generally find that there are almost no examples of inventions where the patent incentive appears to have brought the invention about substantially faster or better than I think would have occurred without patents, and I see lots of examples of costly negative effects of patents.

    Given that patnets are a deprivation of liberty, I think the benefit of the doubt should be made in favor of having less patent restriction. Adding that factor in, my belief at this time is that patents don't seem to be worth it for the public, in practice.

    The recognition part is not the "core" of the patetnt, the core is a specialized alphabet that 1. allows faster text entry and 2. easy to recognize since it's "unistroke" e.g. one single stroke per character. However the patent is riddiculously general, the recognition part IS 1. obvious and 2. known in the science since the 60s, it's really not novel. And specialized simplified alphabets like Unistrokes have been known since the 17th century in various shorthand alphabets in UK and Germany. So in summary, it's excellent that the patent is invalidated.

    This algorithm is neither dumb nor obvious.

    The "dumb" part is that such an obvious algorithm with prior art was granted a patent.

    Palm copied PARC's Graffiti alphabet because the algorithm was so elegant.

    Er, no.

    Graffiti was invented by Palm. Xerox was developing Unistrokes around the same time, and giving lectures about it, and generally not keeping it a secret.

    The patent is not specifically about Graffiti. Xerox basically patented the whole idea of a handwriting recognition alphabet where each letter is a single stroke. And that idea is obvious.

    How can I claim it's obvious? Well, think about it. What's the #1 problem in character recognition on a PDA? Figuring out which stroke is part of which letter. Did the user want to write a 't', or did he want to write an 'i' followed by a '-'? Gee, life is so much simpler with the letters like 'c', 'z', 'o', etc., where there is just one stroke. Hang on... what if all letters were just one stroke? Then we don't need to figure out which stroke is part of which letter!

    Entirely because of the Xerox lawsuit, Palm rolled out Graffiti 2. It's major difference from Graffiti is... not every letter is one stroke. Some are two strokes. It's dumb that they had to do that; there is zero benefit to the consumer here.

    According to the PalmOne press release, the appeals judge ruled that a) this idea is obvious, b) there was prior art, so therefore c) the patent is not valid and PalmOne doesn't have to pay Xerox.

  23. that's not what the patent was on by hak1du · · Score: 2, Informative

    You are wrong on several counts.

    My understanding of the algorithm is that Xerox devides the Graffiti area into 9 ``blocks.'' The recognition algorithm tracks which block the stylus starts in, the end block, and the blocks through which the stylus travels. The recognition is fast and accurate, because each letter is simply an encoding of (start, end, intermediate blocks).

    That recognition algorithm (and numerous variants of it) goes back to the 1960's and has been described in standard textbooks and papers (one example is the Ledeen recognizer, discussed here).

    It is also not what Xerox patented. The Xerox patent is not about the recognition algorithm, it is about having the writer indicate when one character ends and another one starts; one instance of that approach is to use a single stroke for each character.

    In fact, many recognizers using this old algorithm happened to also be unistroke recognizers--it's an obvious idea--which is probably why the unistroke patent got thrown out, and that's a good thing.

    Palm copied PARC's Graffiti alphabet because the algorithm was so elegant.

    If only they had, but unfortunately, Palm did not copy PARC's Unistroke alphabet. Unistroke is a much more effective alphabet than Graffiti 1 or Graffiti 2 and not significantly harder to learn.

    Keep in mind that Xerox had a Palm-like device several years before Palm, complete with networking. Furthermore, the original Palm technical staff apparently knew the PARCTab work quite well. With their patent, Xerox was effectively trying to protect some of their pioneering work in this area, but they failed. That's not necessarily bad, since bad patents may be overall worse than no patents at all.

    But keep the history of this in mind: Palm invented very little of what they are shipping. And, to this day, judging by their nearly non-existent publication record, Palm seems to be doing little or no research. Places like Xerox PARC are in trouble, while Palm has more than half of the handheld market. If companies like Palm keep building businesses on other people's ideas but don't invest in research, who is left to pay for the research?
