Federal Circuit Rules Against Microsoft in $290 Million Patent Judgment

March 12, 2010

The Federal Circuit has offered more guidance on willful patent infringement in a revised ruling in i4i Limited Partnership v. Microsoft Corp. The ruling upheld a lower court's $290 million patent judgment against Microsoft and found that Microsoft must stop selling an infringing version of Microsoft Word 2007. The holding is important because it said that, even if Microsoft had preserved its right to appeal the jury's willfulness verdict, there was sufficient evidence to sustain that verdict, said a lawyer for i4i.
