Just to be clear on this, i4i isn't a patent troll -- it's a a 30 person database design company that shipped one of the first XML plugins for Office and was actually responsible for revamping the entire USPTO database around XML to make it compatible with Word back in 2000. What's more, the patents involved here don't cover XML itself, but rather the specific algorithms used to read and write custom XML -- so OpenOffice users can breathe easy, as i4i has said the suite doesn't infringe. Existing Office users should also be fine, as only future sales of Word are affected by the ruling, not any already-sold products.
