Nintendo said that it won a patent case related to the Nintendo 3DS and other handheld systems.  The Japanese video game giant said it won a patent case in federal court in Oakland, Calif., as it defended itself against a lawsuit by Quintal Research Group.

Federal court judge Saundra Armstrong found that eight of Nintendo’s popular hand-held systems, including the Nintendo 3DS, Nintendo DSi, Nintendo DS and Game Boy Advance systems, do not infringe a patent asserted against those products by Quintal Research Group. Armstrong dismissed the case from Quintal, a “patent assertion” company that many would view as a patent troll.
