Microsoft Word (custom XML) injunction upheld

As reported a few months ago (here, here, here, here & here), Microsoft lost a patent infringement trial to i4i for Microsoft's custom XML feature of Word. A permanent injunction was entered preventing Microsoft from selling, offering to sell, importing or using certain copies of Word with the infringing custom XML editor. The jury also awarded $200 million in damages.

Earlier today, the Federal Circuit affirmed the damages award, and kept the injunction intact, except for modifying its effective date to January 11, 2010. In all other respects, the Federal Circuit affirmed (including the jury's determination that Microsoft's infringement was willful.)
