Microsoft wants to continue war of Word

Miffed Microsoft, having been forced to stop flogging some versions of Word because it was found to infringe patents, wants the US Court of Appeals to reconsider its long-running dispute with i4i systems.

Last month, the US Court of Appeals for the Federal Circuit upheld a previous decision made by a district court in Texas, which ruled in favour of i4i, a supplier of Word XML authoring software.

It told Microsoft to stop selling patent-infringing copies of Word 2007 and Office 2007 software in the US after 11 January 2010.

Microsoft said it has since released a workaround but the firm is still whining, claiming the decision undermines the whole patent protection process. Microsoft’s director of public affairs, Kevin Kutz, said: "We believe the December 22 decision creates with established precedents governing trial procedure and the determination of damages, and we are concerned that the decision weakens judges' authority to apply appropriate safeguards in future patent trials.”

Microsoft owes i4i $300 million in damages, which might also have something to do with why it wants to appeal.

Loudon Owen, i4i chairman said: "This next step of seeking a rehearing was anticipated,"

"We continue to be confident that we will prevail. We look forward to continuing to build i4i's business now that Microsoft is obligated to comply with the terms of the injunction."
