Microsoft has lost its appeal of the injunction in the i4i patent lawsuit that prohibited it from selling versions of Office (specifically Word) in the US that contain code with the capability of opening .XML, .DOCX or DOCM files (XML files) containing custom XML. As a result, the folks in Redmond are scrambling to comply by the required January cutoff date:
This injunction applies only to copies of Microsoft Word 2007 and Microsoft Office 2007 sold in the U.S. on or after the injunction date of January 11, 2010. Copies of these products sold before this date are not affected.
With respect to Microsoft Word 2007 and Microsoft Office 2007, we have been preparing for this possibility since the District Court issued its injunction in August 2009 and have put the wheels in motion to remove this little-used feature from these products. Therefore, we expect to have copies of Microsoft Word 2007 and Office 2007, with this feature removed, available for U.S. sale and distribution by the injunction date. In addition, the beta versions of Microsoft Word 2010 and Microsoft Office 2010, which are available now for downloading, do not contain the technology covered by the injunction.
While we are moving quickly to address the injunction issue, we are also considering our legal options, which could include a request for a rehearing by the Federal Circuit Court of Appeals en banc or a request for a writ of certiorari from the U.S. Supreme Court.
Ed Bott has more information on what specifically Microsoft is doing for its various Office distribution channels and the net is that there does not seem to be any reason for Office sales to grind to a stop in the USA.
