Microsoft's Decade-old Patent On Tree-view Mode! 183

BhaKi writes "Remember the Tree-View mode in many file management applications? It's shocking to know that this omnipresent feature was patented by Microsoft back in 1995 (granted in 1997). I'm not very sure about the implications, though. The patent is so general that it can be related to many things from tree-mode to virtual filesystems. Check out claim no. 3 of the patent for the most clear part."

        I would expect that no lawsuits would be pending, or ever brought to surface - for a few reasons.

        1) They are far from the first to implement such a feature... too much prior art existed

        2) One of the companies that made excessive use of "Tree View" was IBM, when they rewrote OS/2's GUI (without MS's involvement) for OS/2 v2 - which far predates both the application date of this patent and the granted date.

        I doubt they want to sue IBM for something they (Microsoft) did not come up with.

        I also doubt they want to sue anyone else, because doing so would invariably bring IBM into the picture for such reasons (listed in #2 above), as well as force IBM (and others) to bring up the prior existence of such a "structure" which would thus be ground to invalidate Microsoft's patent.

        I am sure that IBM did not come up with this idea - but they did implement it long before Microsoft filed for a patent, and I am sure that the OS/2 GUI patents do cover it, and reference prior art as well.

        This is a (pandora's) box that I doubt Microsoft wants to open. Instead, I think they will use it (or may have been using it, or may consider to use it) for nothing other than trying to force smaller companies without the legal wherewithal to pay them royalties for a technology they did not create.

        Just my opinions.

        Well reading the claims they aren't talking about a treeview file system anyway; they seem to be talking about the system of non-file namespace extensions similar to how they show "Desktop" as a node at a level where it is not in the FS, and "Network", "Control Panel", etc. that can all show up in their Treeview controls interspersed with file system objects. I don't believe Norton Commander or XTree did that. They also are claiming a system of registering these namespace add-ins. None of that seems like any attempt to patent a simple treeview of the file system.
        • At least some of the functionality in the claims was present in HP's Visual User Environment from no later than 1991. Bear in mind that UNIX has had devices in the same namespace as the filesystems.

          There isn't much in the claims (and not clearly covered by prior art) that strikes me as particularly vital for a non-MS operating system.

        It's describing a mechanism whereby a hierarchical filesystem viewer can delegate the ability to display documents to other modules (e.g. a Word Viewer COM control).

        Let's see.

        Claim 1 refers to a file system browser that allows mounting non-file objects into the same namespace as the file system. UNIX did all this, and its "registry" was called /etc/fstab.

        Claim 3 ("a first window for viewing a selected part of the name space and a second window for viewing in more detail an object") describes the approach taken in Mac OS since 1.0, whose Finder had the "Get Info" window.

        But some of the claims are specific and possibly novel. Claim 6: "the non-file system objects include printer objects representing printers." Mac OS from the time of the patent did not have drag-and-drop for printer configuration; instead, it used a desk accessory called the Chooser.

          Mac System 7 had 'desktop printers' a printer icon in the desktop where you could drag a document to print, and double-clicking it opened the queue (where you could manage it by drag&drop the items, not only by 'right-clicking' or menu items, like windows until today)

      • Stated this way, this technology would closely resemble Mac OS X "QuickLook [apple.com]", though this particular feature pointedly does not work in a tree view, but in a separate not-so-modal window that can be summoned. Maybe Apple came up with coverflow view in the Finder and the QuickLook HUD window just to get around this particular patent.

        But reading it myself, it seems more concerned with the presentation of "non-filesystem" objects in the filesystem, so you can open a folder and see email messages or printers

    That's interesting, because a virtually identical view was available in a Wang Laboratories software product called Clearview, released in 1989, which ran on Windows 2.0.

    (Clearview was one of a genre of Windows add-ons, HP NewWave being probably the best known, that plastered improved graphics shells or desktop managers on top of Windows).

    And Clearview itself was nothing more than an improved version of a directory display that was used in the Wang Laboratories OIS circa 1977. They were logically the same, although visually different because the OIS was constrained by having a character-oriented screen. At least within Wang itself, Clearview's directory display was regarded a spiffy bitmapped graphic version of the OIS's display.

    I seriously doubt that Wang was first or even close to first, but Wang was definitely shipping large numbers of commercial products that offered tree views of directories long before 1995.

      No, the prior art just invalidates the claims it applies to. That is why patent claims are written how they are, it goes something like this:

      2. A thing as in 1 that also does something more specific
      3. A thing as in 2 that also does something even more specific
      And so on. If claim 1 gets thrown out, you can still fall back on 2... (Of course it can get much more complicated than that as there can be any number of broad claims and any number of more specific claims dependent on them)

      Each claim of a patent is presumed valid independently of the validity of the other claims. See 35 U.S.C. Sec. 282 [cornell.edu]. If one claim is invalid, then other claims that include additional or different limitations will still be presumed valid until proven otherwise.

      You may have noticed that patent claims themselves form a hierarchy. At the top of the hierarchy are the independent claims. You can recognize them because they do not refer to other claims in the patent. Then there are dependent claims. These are claims that add additional limitations to the claims from which they derive. You can recognize them because they refer to other claims in the patent.

      The independent claims, which have the fewest limitations, are the easiest to knock out with prior art references. The dependent claims, especially dependent claims that depend on dependent claims, are the hardest to knock out with prior art references, but are easier to engineer around (all you have to do is ensure that your own implementation does not include one of the limitations or its equivalent; but you still have to be careful because the courts often find weird equivalents when it comes to litigation). Patent practitioners usually draft a variety of independent and dependent claims to make a patent harder to fully invalidate or engineer around.

      Because it is hard to knock out all the claims of a patent, defendants in patent litigation often look to ways to attack a patent as a whole. Defendants often accuse the patent applicant of withholding information from the patent office, such as knowledge of prior art or the best mode embodiment of the patent. They may even try to find inventors who were not named on the patent application and license the patent independently from them.
