This injunction only applies to new Microsoft Word and Microsoft Office licenses purchased from Microsoft on or after January 11, 2010 in or for deployment in the United States or its territories. If you are only using licenses acquired prior to January 11, 2010, you do not need to take any action.[…]
[…]If you plan future deployments of Microsoft Word 2003 and 2007 or Microsoft Office 2003 and 2007 based on licenses that you purchase before January 11, 2010, no action is required and you may continue to deploy your existing version of these products.
