A Seattle judge has ruled in favour of Microsoft in one of two patent trials putting Redmond up against Google and its Motorola Mobility unit, leaving it with a substantially smaller royalties bill to pay.
Motorola wanted Microsoft to cough up cash on patents relating to the Xbox console - as much as $4 billion each year. But district judge James Robart said a more appropriate payment would be $1.8 million, practically nothing considering and much closer to Microsoft's calculation of $1 million a year - or 0.045 percent of Motorola's original claim. The patents are related to wireless and video technology.
Microsoft's deputy general counsel, David Howard, said in a statement that the decision is "good for consumers" because it "ensures patented technology committed to standards remains affordable for everyone".
Later this year, a separate patent case between the two will go to courts - and declare whether or not Motorola failed to licence standard and essential patents to Microsoft on fair terms, Reuters reports.
Earlier this year, Microsoft also saw off Google in a dispute over the H.264 codec.
Google was believed to have picked up Motorola Mobility in a multi-billion deal largely to bolster its patent portfolio. It, Microsoft, Apple and others have been involved in patent battling since the emergence of the smartphone boom - the winners so far largely being the lawyers and the odd bit of publicity.
