On Tuesday, Microsoft lost at the U.S. federal court of appeals in a landmark case that will force the software maker to redesign its flagship word-processing program. The US appeal court upheld a $290-million US judgment against Microsoft in the patent battle launched by Canadian company i4i Inc.  The injunction comes into effect in January to stop sales of Microsoft Word software which infringes i4i’s software patent for XML editing. Microsoft claims it is reviewing its legal options.
