Here is some breaking news. A judge in the Eastern District of Texas has ruled that Microsoft violated a patent obtained by Toronto based i4i, Inc. related to XML technology. He has ordered an injunction, that will take effect in 60 days, prohibiting Microsoft from selling or importing to the United States any Microsoft Word products that have the capability of opening .XML, .DOCX or DOCM files (XML files) containing custom XML. Ummmm, that would mean Word 2007 and the upcoming Word 2010.
Before everyone panics, or rejoices in some cases, a couple of things should be noted. Much of what I have read describes the Eastern District of Texas is a haven for patent litigation plaintiffs and Microsoft (and others) believe that they have a high likelihood of succeeding on appeal. Another item of note is that Microsoft recently obtained their own XML patent.microsoft, word 2007, word 2010
