Microsoft has been ordered to pay i4i $290-million after losing an appeal to strip Word’s custom-XML editor. The only other option for Microsoft was to stop selling Word completely. According to a representative: “after its effective date, the injunction prohibits Microsoft from selling, offering to sell, importing, or using copies of Word with the infringing custom XML editor.”

The company sued Microsoft in March 2007, alleging the software superpower willingly infringed on a 1998 i4i patent by building a method of processing custom XML into one of Microsoft’s biggest cash cows, starting with Word 2003.
