Forgent Squeezing Money Out Of JPEG, Other Patents 305

Posted by simoniker from the delightful dept.
deman1985 writes "Forbes reports that Forgent Networks, Inc., developer of scheduling software and holder of a number of technology patents, has settled with both Adobe and Sony for JPEG patent infringement and is going after numerous others to collect their fair share of royalties. The company also plans to go after PVR companies, including TiVo Inc, and MP3 player makers for other various patents they claim to hold. Sounds like more fun in the courts for everyone!" We previously reported on Forgent's JPEG patent shenanigans back in April.

        PNG is good for its own purposes, but it's no .jpg replacement. JPG = lossy and phenomenal compression, where PNG = nonlossy and kind-of-average compression.

        Take a high resolution screenshot with any complexity and save it as a PNG, and you might be lucky to get it in under 600KB, where a .jpg could get the same point across in under 100KB.

          A screenshot is a very bad example. It's almost NEVER better to save screenshot using a lossy compression algorithm such as JPEG. Screenshots are always better as GIF/PNG.

          JPEG is designed for compressing PHOTOGRAPHS and nothing else. It severely messes up screenshots and text unless set to extremely high quality. But if you set it to extremely high quality, the file size is usually much bigger than a PNG would be anyway.

          I'm amazed at how many authors of programming articles still don't know basic web fundamentals such as how to save a screenshot.

          To summarise:
          Save screenshots/diagrams/charts (large areas of flat colour/text) as PNG/GIF
          Save photographs as JPEG

            It really depends what you are taking a screenshot of. A game screen (probably the most common screenshot type in existance) is going to be horrible with PNG unless you're taking screenshots of Pong. Even desktops are bad unless you unset that nifty photographic background and or pictures on a webbrowser etc...

            The point is, once the complexity of the image goes above "very simple" JPEG is going to give you a smaller file nearly every time. There are precious few images worth saving as a file that are "very simple". Worse, PNG ramps up in size very quickly as the complexity increases, which is what the original poster was talking about.

          PNG is a good replacement for .gif, but not for .jpg, yet.

          It never will be and never was intended to be, for exactly the reason you stated above: PNG is lossless, while JPEG is lossy. These are two different types of tool, which serve two different purposes. PNG will never achieve the compression rates of JPEG. Just use the right tool for the job.

          Would flac ever replace or eliminate the need for mp3 and ogg? No, for the same reason. flac, being lossless, serves an entirely different purpose than mp3 and ogg.

          (Some time in the future, I would imagine that disk space will become so cheap and abundant that lossy compression is unnecessary, but in that case I would say that cheap disks -- not lossless compression -- have eliminated the need for lossy compression.)

        This cannot work for the simple reason that JPEG is designed specifically for lossy compression of photographs and other complex images. Think of it as mp3 type compression - discarding data with quality decreasing proportional to size. A great tool for the dialup age.

        PNG compression is entirely unsuited to this purpose - the level of compression for these types of images is terrible. Simple diagrammatical type images compress very well in PNG. Think of it as a zip type compression. Repeated elements of the image, such as whitespace which JPEG doesn't handle very well, are well suited to PNG. Ever zipped a log file? Plenty of repeated elements, great compression.

        Converting GIF to PNG? Fine, you'll likely end up with smaller files as a bonus.

    This has me thinking about the patent game large companies play. Take IBM, Apple, Microsoft - all with gigantic patent portfolios, and products that use many of them (and probably many of those of the other companies too). When IBM infringes on an Apple patent, they get together, cross license patents under certain conditions, and go on their merry way.

    This is all fine as a defense against a company that actually has a product. But take something like these smaller companies, who only own a patent portfolio, or perhaps one big patent altogether, and no products. They find that Adobe infringes on their patent and... Adobe have no recourse. No cross licensing to be done as the smaller company has no product. The smaller company may even be privately owned, so there's no chance of a simple cheap buyout.

    While we're all looking at MS, Apple, IBM, Adobe etc and going "tsk! omg!" as they acquire yet another silly patent, they're not necessarily the ones who're going to be a pain in the butt about it, it's the smaller rogues like Forgent, or Acacia etc.

      JPEG 2000

      JPEG 2000 [jpeg.org] is "the" successor to JPEG (designed by the same team), and was noticeably better than JPEG when I checked out quality vs size, but it's patent encumbered. It is however intended to be royalty and license-fee free.

      Elysium Ltd has developed a freeware Netscape plugin [elysium.ltd.uk] to make IE, Opera and Netscape browsers able to view JPEG 2000 pictures. This plugin is for Windows, and I don't really know if there are others for other platforms.

      DjVu

      DjVu [djvuzone.org] was designed for the web to replace common formats like JPEG, GIF and TIFF. Although designed primarly for compressing text, it's very efficient at regular photos as well, and should compress similarly as JPEG 2000 (about half the size of JPEG with similar quality).

      DjVuLibre [djvuzone.org] is a GPL licensed open source implementation that includes plugins, viewers, and encoders for this format.

    Patents are designed to defend against inventions. If I patent something useful, but don't actually have an implementation, I'm using the system to stifle others, and not really giving anything back.

    In order for something to be an invention, it needs to have an implementable form.

      I would like to agree, and certainly agree with the spriti of what you're saying, but there is a practical problem too.

      Suppose I succesfully work out all the problems and design the perfect cold fusion-based reactor. There is no possible way for me to implement it - I have to go to an energy company to get a power plant built (at the very least, a bank who will loan me the utter fortune I require to construct it).

      At this point, under the changes you suggest the device is not patentable since it has not yet been implemented. What is to stop an unscrupulous energy company, or bank, or indeed anyone who gets wind of it from taking my design and implementing it themselves with no further input from me? Worse still, once they have the implementation it is they who will profit from obtaining a patent, not me.

      So the "no patent without implementation" idea is flawed. It's a shame, because it sounds like a good way out. But it wouldn't work as described.

      Incidently, I refused to have my name listed as the co-inventer on a patent my company wanted to file because I considered it so trivial as to be silly. I don't want my name associated with patent abuse, and if more people took that approach this problem simply wouldn't occur. That's a pipe-dream though.

    The numbers don't seem to add up. The article states:

    the past two years, the company has made about 90 percent of its revenue from patent negotiations, and its software has yet to get much of a foothold.

    In its fiscal 2003, for instance, software sales were just 8 percent of the company's $53.9 million in sales.
    These quotes say that $53.9 million in sales (which is consistent with what I find on Yahoo Financial [yahoo.com]comes for 90% from patent negatiations, and 8% from software sales. Nowhere on the net can I find anything about where that other 2% comes from (they don't seem to do any consulting for instance).

    Then there's these quotes:

    Already, Forgent has reaped nearly $50 million by claiming that one of its patents covers JPEG, the popular standard for digital images.

    Then there's Jenkens & Gilchrist, the Dallas-based law firm handling enforcement of the JPEG patent. Under a fee agreement, Jenkens receives 50 percent of the revenue from licensing the patent, plus some expenses. The law firm's take so far is an estimated $50 million.
    The first one says Forgent made $50 million on jpeg patents so far. The last claims the lawyers get half, and that is also $50 million.

    Not sure what I should think of a company that doesn't succeed in having it's numbers correctly communicated. I do know however that $50 million is peanuts on a global scale. Looking at Forgent' share price, the stock markets seem to agree with me.

    • The first one says Forgent made $50 million on jpeg patents so far. The last claims the lawyers get half, and that is also $50 million.

      No contradiction. Total amount: $100m. Forgent's cut? 50%, ie. $50m. Lawyer's cut? 50% ie. $50m.

      It just says Forgent has reaped nearly $50m, not that the gross licensing fees were $50m. For their statement to be correct, you can extrapolate the gross to be $100m.

    Actually, I realy mean it !

    According to the foot note of this [imaging-resource.com] article,
    they don't have a patent for the JPEG compression standart it self,
    but for the run lenght encoding (RLE) compression which is used in one of the latest stage of JPEG compression.

    Which means two things :
    - It is not a threat to lossy compression.
    All the strenght of JPEG comes from the DCT (discret cosine transforme) and the subsequent quantization, which convert the picture into a stream of more compressible values repetitive values (and thus perfom the actual "lossy" steps).
    RLE isn't the only way for compress these values,

    One can use algorithms similar to those used in the final steps by Xiph's (!) Speex or by Monkey Audio (=Rice).

    So one can imagine that Xiph could easily create a temporary JPEG replacement until some realy better (Wavelet based ?) patent-free format is created.
    (Hence my stupid joke at the begining).

    - Second thing :
    There's probably A LOT of prior acts for this patent, as LZW was one of the most popular compression algorithme on the old personnal computers of the 80s.

    The JPEG committee investigated the patent claims in 2002 and found that they were invalidated by prior art. Nevertheless, between 2002 and 2004 Forgent was able to obtain about $90 million by licensing their patent to some 30 companies. In April 2004 Forgent sued 31 other companies to enforce further license payments. In July of the same year, a consortium of 21 large computer companies filed a countersuit, with the goal of invalidating the patent.
    I guess the prior art does not stand in court.

    Actually Forgent doesn't own JPEG it owns (according to the last Slashdot article) run-length encoding which is used in many more things than JPEG including fax compression. To say RLE is what makes JPEG would be misleading, to sue people for it would be to sue CD manufactures because you came up with the idea of making the disk a circle shape. Now what RLE is, is basically counting the number of repeating symbols, in a line, in a data stream, and replacing that sequence with a special symbol that basically says "there are 352 X's here" or "352X" etc. That basically means Forgent is not only a pile of shit, they are 352shit. Looking at the DCT algorithm in JPEG it is a masterful weave of mathematical genius as beautiful as the scantily glad Victorias secret models it purveys to millions around the world and had Forgents team of dedicated masters spent years perfecting this and had they bled their souls and bodies daily into the project i might find it in me to see an ounce of respect and maybe they would deserve some royalties from those who would use the algorithm for solely commercial gain. but they don't and they didn't. They bought RLE and now they want to milk the world for a 'technology' even a judge could understand!

    I'm also against software patents but I think it's too simple an explanation to blame the large corporations only. Yes, the big organizations typically want software patents, and I see them how they push very hard for software patents in the EU where we have that ongoing legislative process.

    However, I also see the major mistake of small and medium-sized enterprises: They don't act. Large corporations understand that politics affect business, so they view political activities as part of their business. Small and medium-sized enterprises are usually run by people who believe that it's "prudent" to focus on the "core business" and not to do anything serious on the political front.

    The narrowmindedness and ignorance of most small and medium-sized enterprises makes it very easy for the large corporations to get what they want, and to defend it later.

    Look at most industry associations: They claim to speak on behalf of numerous small companies but are pretty much under the control of a few large members. An organization like the SIIA should fight against software patents every day. It should be their #1 priority because nothing is a bigger business risk to software companies than those absurd software patents. Instead, the SIIA just asks for more funds to be provided to the USPTO. Sure, with more resources, the USPTO may be able to examine patent applications more carefully. Still the real solution is to do away with patents on computer program logic, i.e. mental steps. And where are the organizations, except for some open source and civil rights organizations, that truly fight against software patents?

    Maybe, at the end of the day, many small and medium-sized enterprises just pay the price for political ignorance and inactivity. Right now, there would be an excellent chance to get software patents abolished in the EU, and that would be a signal for other regions of the world (especially if things work out well for the EU, and I'm quite sure they would because software patents stifle innovation and adversely affect economic growth).

    The ex-Jenkens lawyers filed a counterclaim to recover millions of dollars in past and possibly future fees they say they're entitled to as the architects of Forgent's patent-licensing strategy.

    So basically, these lawyers patented the business model of suing other companies for patent infringement and are now trying to collect royalties on Forgent collecting royalties from the JPEG patent. Follow that?

    But it gets better:

    Already, Forgent has reaped nearly $50 million...

    Jenkens receives 50 percent of the revenue from licensing the patent, plus some expenses. The law firm's take so far is an estimated $50 million.

    So, let me get this straight:

    • Forgent has paid out 50 Million in legal fees, so that:
    • Forgent could receive 50 Million in patent royalties, and
    • They now owe the lawyers half of any remaining royalties they collect...

It seems to a popular activity for patent-holders lately to wait quietly by while others infringe on their patents. They wait until the company becomes big enough, then they bounce on the offenders like a little fat kid walking through the desert who sees a piece of chocolate cake.

    That's what has bothered me from the beginning about SCO (I know it's not a patent issue here, but close enough). Why hadn't anyone said anything about Linux stealing System V code before? It's not like Linux is all that new. It appears that they just waited until someone with deep enough pockets was close enough to Linux that they could attack.

    There should be a law enacted where if you know that someone is infringing on one of your patents, you have one or two years to litigate. After that point, your rights to litigation would be revoked. Now it would be difficult to prove prior knowledge of the infringement, but it's better than our current system.
