A jury had previously ruled in Dallas division of the Northern Texas District Court in September 2017 that Nintendo’s Wii and Wii U controllers were infringing on iLife’s motion-sensing patents, and awarded US$10.1 million in damages to iLife.
Nintendo’s position in the original 2013 lawsuit was that iLife’s patent was not properly written and therefore was invalid.
A federal court in Dallas, Texas overturned a previous decision against Nintendo of America in a lawsuit by iLife Technologies on January 17.
However, in the January 17 ruling, the court ruled that iLife’s patent was overly broad in covering the “concept of using motion sensors to detect motion,” and invalidated the patent, and also nullifying the previous jury award.
