Microsoft released a supplemental patch for Office 2007 that is required for the United States in order to comply with the injunction of August 12, 2009.  From the Microsoft OEM Partner Center:

After this patch is installed, Word will no longer read the Custom XML elements contained within DOCX, DOCM, or XML files. These files will continue to open, but any Custom XML elements will be removed. The ability to handle custom XML markup is typically used in association with automated server based processing of Word documents. Custom XML is not typically used by most end users of Word.

Judge Davis of the U.S. District Court for the Eastern District of Texas entered a final judgement against Microsoft today, following a jury verdict issued on May 20, 2009.

The suit originated in 2007, when Canadian software firm i4i Ltd sued Microsoft for infringing their U.S. Patent 5,787,499.  The suit alleged that Microsoft knowingly infringed on this patent in its Word application and its Vista operating system.

The judgement entered today includes a permanent injunction prohibiting Microsoft from selling or importing to the United States any Microsoft Word products capable of opening .XML, .DOCX, or DOCM files containing custom XML.  Microsoft must comply with the injunction within sixty days.  Microsoft is also required to pay total damages and interest of more than $290 million to i4i Ltd.
