Microsoft is telling new corporate customers to update versions of its Office suite and Access software package following a 2005 patent infringement ruling that required Microsoft to remove the patented software from its products. Microsoft on Monday began notifying customers they are required to patch new corporate installations of Office Professional 2003 and Access 2003 to install Service Pack 2. Corporate customers with new installations of Office XP Professional and Access 2002 are required to install a special patch, Microsoft said. In June, a California court ordered Microsoft to pay Guatemalan inventor Carlos Armando Amado US$8.9 million for infringing his 1994 patent for software to help transfer data between Microsoft Excel spreadsheets and the Access database using a single spreadsheet. The California jury rejected nine of the 10 patent claims Amado filed in the lawsuit. The court required Microsoft to remove the patented software, a Microsoft spokesman said.
