U.S. Court of Appeals for the Federal Circuit upholds lower court decision that found Microsoft infringed an XML-related patent held by i4i Ltd and orders world's largest software maker to stop selling its popular Word program effective Jan. 11.

Microsoft lost its appeal Dec. 22 of a $290 million judgment that found the world's software maker infringed an XML-related patent held by i4i Ltd of Canada.

Small IT companies have a history of winning patent lawsuits against IT giants in the Texas court system. In 2006, for example, Anascape managed to win a $21 million judgment against Microsoft and Nintendo for allegedly violating its patents relating to game controllers; as recently as July, a tiny IT outfit named Tsera sued 23 tech giants, including Microsoft and Apple, over a touch-screen patent.
