Patent Injunction: Microsoft Ordered to Stop Selling Word

By Gene Quinn on August 12, 2009

Yesterday, Leonard Davis, a United States District Court Judge in the Eastern District of Texas, ordered Microsoft Corporation to stop selling Word, an order that becomes effective in 59 days (i.e., 60 days from yesterday).  The permanent injunction issued after the conclusion of a patent infringement lawsuit brought by i4i Limited Partnership, a litigation where Microsoft was found to infringe U.S. Patent No. 5,787,449, which is titled Method and system for manipulating the architecture and the content of a document separately from each other.  This permanent injunction follows a $200 million verdict against Microsoft, a verdict which issued in late May 2009.  Shortly after the verdict was announced, Michel Vulpe, founder of i4i and inventor of the patent, said: “We are very pleased with the verdict. The jury heard extensive testimony and evidence and concluded that Microsoft had indeed infringed our patent. We feel vindicated with this result.”  Not surprisingly, According to USA Today, Microsoft plans to appeal.  A spokesman for Microsoft said: “We are disappointed by the court’s ruling.  We believe the evidence clearly demonstrated that we do not infringe and that the i4i patent is invalid.”

The permanent injunction ordered by Judge Davis states (in part):

Microsoft Corporation is hereby permanently enjoined from performing the following actions with Microsoft Word 2003, Microsoft Word 2007, and Microsoft Word products not more than colorably different from Microsoft Word 2003 or Microsoft Word 2007 (collectively “Infringing and Future Word Products”) during the term of U.S. Patent No. 5,787,449:

1. selling, offering to sell, and/or importing in or into the United States any Infringing and Future Word Products that have the capability of opening a .XML, .DOCX, or .DOCM file (“an XML file”) containing custom XML;

2. using any Infringing and Future Word Products to open an XML file containing custom XML;

3. instructing or encouraging anyone to use any Infringing and Future Word Products to open an XML file containing custom XML;

4. providing support or assistance to anyone that describes how to use any infringing and Future Word Products to open an XML file containing custom XML; and

5. testing, demonstrating, or marketing the ability of the Infringing and Future Word Products to open an XML file containing custom XML.

Those unfamiliar with Microsoft litigations of the past may find it peculiar that Judge Davis spoke of “products not more than colorably different from Microsoft Word 2003 or Microsoft Word 2007.”  Remember if you will one of the arguments made in the late 1990s by Microsoft during its antitrust saga with the Department of Justice.  The Department of Justice had been looking into whether Windows 95 was an illegal monopoly and achieved a consent order with Microsoft in which Microsoft agreed not to engage in certain specified activities with respect to Windows 95.  Shortly thereafter, Microsoft released Windows 98.  The DOJ became apoplectic over the fact that Microsoft took the position that the consent order ending the previous antitrust inquiry was not applicable to Windows 98.  They likely became even more red-faced when the Judge agreed with Microsoft.  That was one of the most shrewd pieces of business and lawyering I have ever seen, perhaps third most shrewd, behind only Bill Gates selling the original Microsoft operating system to IBM before he owned it (number 2 on the shrewd list) and Bill Gates then convincing IBM he really didn’t want to sell it after all, only license it (number 1 on the all-time shrewd list).  So, mention of future and only colorably different products has to fall into the “catch me once, shame on you, catch me twice, shame on me” category.

In any event, the permanent injunction does not apply to Infringing or Future Word Products that:

  • open an XML file as plain text;
  • upon opening an XML file, applies a custom transformation that removes all custom XML elements;
  • providing support or assistance to anyone that describes how to use any of the infringing products to open an XML file containing custom XML if that product was licensed or sold before the date of the permanent injunction, which was August 11, 2009.

The Final Judgment entered by Judge Davis pursuant to Rule 58 of the Federal Rules of Civil Procedure, which was accompanied by a 65 page Memorandum, explains:

  • Microsoft willfully infringed U.S. Patent No. 5,787,449
  • The ‘449 patent is valid and enforceable
  • Vulpe did not commit inequitable conduct with respect to the ‘449 patent
  • damages are not barred by laches
  • The plaintiff is awarded $200 million in damages
  • The plaintiff is awarded $40 million in enhanced damages
  • The plaintiff is awarded $144,060 in post-verdict damages
  • The plaintiff is awarded $37.097 million in pre-judgment interest, and $21,102 in interest between verdict and Final Judgment
  • The plaintiff is entitled to post-judgment interest pursuant to 28 USC 1961 for the time period between Final Judgment and payment by Microsoft
  • Pending motions not previously resolved are denied

We shall see what Microsoft does from here, and while Microsoft says they will appeal history demonstrates that Microsoft typically does not take an appeal all the way through to a decision by the Federal Circuit, even if an appeal is filed.  So I would anticipate that at some point Microsoft will cut a deal and settle the case, likely after filing the necessary paperwork to appeal the decision and at least raising enough questions for the plaintiff for them to prefer to accept cash in hand rather than continue to roll the dice on appeal.

In the meantime, do not look for any major changes to Word 2003 or Word 2007.  Many pundits are already opining that Microsoft should be able to modify Word easily enough within the next 59 days to allow it to be sold, and that is assuming that Microsoft is not capable of obtaining a stay of Davis’ order pending appeal.  Nevertheless, Microsoft has lost a pretty significant amount of money, even for them, and the prospects of needing a work-around within 59 days are real enough to cause some sleepless nights in Redmond.

    Can anyone believe after so many years of Microsoft Word that now it is found to infringe such a patent, a patent as far as I can understand, is such a patent I have mentioned before as being one that by claim design covers underpinning technology. The truth is, that computers in this case, used for what was once done by typewriters, before then it was done by hand; what claim(s) that this patent holds, in my opinion, that this patent holds some idea not having existed before ?. Well enough said, however this is one of many best examples of the danger in the US patent system today in my opinion, for everyone, not just Microsoft.

    As far as I can tell, the patent is really about having an XML (or similar) document without the XML tags being embedded in the document. Rather, the tags are in another file with a table describing where they should be in the original document, and the two files are composed together when the document is displayed or edited.

    It turns out there’s probably prior art for exactly this from 1968, but I don’t know what effect that will have on the Microsoft case:

    I think that the suit and decision are ridiculous. The i4i patent is too general and all-encompassing, and there are potentially so many ripple effects that will hurt us all. My detailed analysis:

    Thanks for your comment, but exactly why do you think the decision is ridiculous and the i4i patent too general? I read your analysis, and it seems that you think the patent discloses only a concept and not the structure. Can you elaborate a bit?

    What steps must be performed to open an .XML file that contains custom XML that are not necessarily also performed when opening an XML file that does not contain custom XML?
    This is not a rhetorical question, I really want someone to explain this, please.
    Is the injunction language “capability of opening a .XML, .DOCX, or .DOCM file (”an XML file”) containing custom XML” just a long-winded way of saying “capability of opening a .XML file”, or is there more to this technology than meets the eye?

    This is simply poetic justice. Live by the patent, die by the patent.

    For a quite refreshing view from a non-legal and technical [erson (without the usual fervent anti-patent rhetoric), try this link:

    Even a cursory reading of US Patent 5,557,722 (DeRose and Vogel, filed 1991) shows that it covers almost exactly the same things as the ‘499 patent. It’s even in the same fairly narrow domain of processing arbitrary SGML documents, and it’s very specific about separating out the content and structure (the implementation described literally stores them in separate persistent files). So IMHO, the ‘499 patent should not be upheld, or at the very least should be narrowed to a tiny sliver of what it now claims.

  9. Gene Quinn August 18, 2009 3:41 pm


    It seems that there are quite a few who think they have prior art that could invalidate or limit the claims of the ‘499 patent. If anyone wants to write something up in about 1000 words (+/-) I would be interested in publishing such an article.



  10. Lucian August 19, 2009 11:31 pm

    I think that most of the 5,787,449 patent should be invalidated as is in public domain from the beginning of the 70’s.
    I am talking about basic elements of the “multi value” database concept which are found in products such as IBM U2 databases, PICK, jBASE, Revelation, QM database etc.
    The concept in question is about having a separate data part and a separate dictionary part, or metacodes. as in the patent wording.
    Therefore in a multi value database to get a view of your data you have to apply the dictionary, which is there for the purpose of formatting, in the same way the patent prescribes.
    Also, exactly as described in the patent, one data file may have multiple dictionaries and each dictionary may have multiple definitions for the same data item therefore you may have multiple views of the same data.

    Microsoft said they filed a motion August 18th with the U.S. Court of Appeals for the Fourth Circuit asking for an expedited appeal.

  12. Gene Quinn August 20, 2009 11:44 am

    Why in the world would Microsoft file an appeal with the 4th Circuit in a matter that the 4th Circuit clearly does not have jurisdiction over? Any appeal would have to be filed with the Federal Circuit.

    Sorry Gene, IP Law360 was incorrect, you are right!

  14. Gene Quinn August 25, 2009 12:03 pm

    No problem Katie. I won’t be too harsh on IP Law360. Those types of mistakes happen from time to time. With Microsoft being involved I also wondered if there might be a procedural angle here, or if perhaps they were trying to provoke some kind of stall or delay by going to the 4th Circuit. You never know when Microsoft is involved, and frequently they are one step ahead so you never know what legal maneuvering they may be trying to accomplish.
