Alcatel-Lucent's lawsuit alleging that Microsoft infringed on its speech to text technology has been thrown out the door by a U.S. federal judge. According to the ruling, Microsoft was found not guilty of infringing on technology held by Alcatel-Lucent.

The win for Microsoft comes shortly after it lost another case to Alcatel-Lucent where Microsoft was ordered to pay $1.54 billion USD in damages. The award is the largest in U.S. history for any patent case.

Judge Rudi Brewster dismissed all of Alcatel-Lucent's arguments, claiming in summary judgment that Microsoft clearly does not infringe upon any patents. A jury trial was set to begin on March 19th of this year, but since all claims were dismissed, the trial will no longer take place. Alcatel-Lucent said it will appeal the ruling. "We've made strong arguments supporting our view," said Joan Campion, a representative for Alcatel-Lucent.

Alcatel-Lucent launched a patent infringement case against Microsoft for technologies used in the Xbox 360. More than seven patents were part of the claim and included technologies used for processing video and communicating online.

Despite Alcatel-Lucent's plan to appeal, Microsoft stated that the federal ruling proved it did no wrong doing. "This ruling reaffirms our confidence that once there's judicial review of these complex patent cases, these Alcatel-Lucent claims ultimately won't stand up," said Tom Burt, deputy general counsel to Microsoft.

Alcatel lost a previous suit against Microsoft that started in 2003, where Alcatel also filed for patent infringement.  The company still has several high-profile patent cases pending against Microsoft; many are due for summary judgment in the next few weeks.
