Microsoft has been fighting a case against developer i4i, who holds patents relating to the custom tagging of XML files. The developer brought suit against the software giant accusing them of patent infringement. It seems like the court agrees with them, too – as Microsoft lost the battle. Technically, this means they have to pull the product and otherwise suspend sales of both MS Word 2007 and MS Office 2007 (since it includes Word) by January 11th, 2010. Microsoft knew this was a potential outcome, even if they probably didn’t expect it, and issued a press release affirming the fact that they’ll have a new revision of the software ready to take the place of the infringing one. Does this affect you? Almost certainly not – even if you took advantage of the custom XML tagging features, your copies won’t be affect – Microsoft won’t be disabling the pre-existing copies, just changing them from here on out.
