A Texas judge ruled Tuesday that Microsoft cannot sell one of its flagship products, Word, in the United States because of patent infringement.

You read that right: Microsoft cannot sell Word, the judge ruled.

Judge Leonard Davis, of the U.S. District Court for the Eastern District of Texas, ordered a permanent injunction that "prohibits 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," according to an announcement by the plaintiff, Toronto-based i4i Inc.
