Speech coding technology used in several Microsoft applications does not infringe on an Alcatel-Lucent patent, a US federal judge, quoted by an Associated Press report said.
The Associated Press report said the summary judgment from a US District Court judge in San Diego dismissed Alcatel-Lucent's claim that Microsoft's Windows Media Player, NetMeeting and Messenger programs call on its patented speech pattern analysis technology.
The case was set to be heard later this month, the report added. Alcatel-Lucent said it plans to appeal the decision.
Judge Rudi M. Brewster's decision followed last week's jury ruling in the same court that Microsoft's music player software did infringe on two Alcatel-Lucent patents related to encoding and decoding audio into the digital MP3 format, the report said.
The jury ordered Microsoft to pay $1.5 billion in damages.
