The lawsuit started way back in 2010. In April of this year, the console was, but the US International Trade Commission said it had to take a second look, and soon decided otherwise.
The case originally included five patents, with the last one related to a way of pairing the console with accessories. Judge David Shaw has ruled this doesn't infringe Motorola's patent, but the case isn't over yet. Google ---- will have the Commission review the findings, and Judge Shaw's ruling will be subjected to a six-person examination. The Big G will also try and impose an import ban on the console.
Despite not being out of the woods yet, Microsoft welcomed the ruling. "We are pleased with the Administrative Law Judge's finding that Microsoft did not violate Motorola's patent and are confident that this determination will be affirmed by the Commission," David Howard, Microsoft's corporate vice president and deputy general counsel, said in a statement.
Google was less chuffed. "We are disappointed with today's determination and look forward to the full Commission's review," Google spokesperson Matt Kallman said in a statement.
Motorola originally filed the complaint in response to Microsoft demanding royalties on phones using Google's Android mobile operating system. for companies making Android devices, and successfully stopped Motorola phones from using ActiveSync, which lets you synchronise schedules across your desktop and mobile.
Google wasn't taking it lying down, so snapped up Motorola and its vast patent library, and hit back at Microsoft. (It also bought Motorola to bolster itself against the vast might of Samsung, in case it became too big for its own good.)
