In its motion, Microsoft asked an appeals court to halt that injunction and also to speedily hear the company's appeal once it is filed.

The stakes are high and alternative productivity suites such as OpenOffice.org or even Google Docs certainly would love to capitalize on this. There are a few possible outcomes, though, and somehow I doubt Office ceasing to be available is one of them. Microsoft could still buy some time with the appeal to work on non-infringing versions of Word or perhaps reach an out-of-court settlement with i4i.
