In 2007, i4i, a 30-person document collaboration firm based in Toronto, sued Microsoft for infringing i4i's US patent (filed in 1994, issued in 1998), whose claims are directed to editing XML, a programming language for controlling how a document's contents are displayed.  In August, a Texas trial court ordered Microsoft to pay roughly $300,000,000 in damages and issued an injunction, requiring Microsoft to remove the infringing code from its Word products.  In December, the Court of Appeals for the Federal Circuit upheld the trial court, chalking up a big win for the little guys.
