Microsoft's legal battle against Canadian firm i4i has been a complete disaster from the very outset. Last August, Microsoft was ordered to pay i4i $290 million in damages by a federal judge in the U.S. District Court for the Eastern District of Texas after certain versions of Word were found to be infringing on an XML-related patent held by the Canadian firm. The fine was accompanied by an injunction barring the sale of infringing versions of the popular word processing software.
All subsequent attempts to turn the tide also proved unsuccessful. Now, Microsoft has filed a writ of certiorari with the U.S. Supreme Court , asking it to review the lower court's decision. This hasn't come as a huge surprise to i4i, which is confident that it will once again “prevail” over its storied rival.
