The case, which Microsoft says it will appeal, is related to user interface technology, MarketWatch reported.

The jury Friday found that while Microsoft did not infringe on the video-coding patent, the Redmond, Wash.-based company did infringe the two user interface patents.

Paris-headquartered Alcatel-Lucent had been seeking $1.75 billion in damages in U.S. District Court in San Diego. The case originated in 2003, MarketWatch said.

As a part of the case decided last year, Microsoft was ordered to pay $1.5 billion for infringing Alcatel-Lucent patents related to MP3 technology, but a judge later reversed that decision.

"We feel confident the verdicts will be overturned, just as the court overturned a verdict last year by a San Diego jury in Alcatel-Lucent's favor in a dispute with Microsoft concerning widely used MP3 technology," Microsoft deputy general counsel Tom Burt said in a statement.
