On Nov. 13, 2015, Nintendo won a patent case in California federal court, the second time Nintendo has prevailed against Technology Properties Limited LLC, Phoenix Digital Solutions LLC and Patriot Scientific Corporation, all of which are patent-licensing companies. In July 2012, plaintiffs sued Nintendo both in California federal court and in the International Trade Commission. In February 2014, the ITC held that Nintendo did not infringe the asserted patent. The plaintiffs chose not to appeal that decision, but insisted on continuing to litigate the same patent and many of the exact same issues before the California federal court. Nintendo has now won that case as well, with the court holding that Nintendo’s systems, including Wii U and Nintendo 3DS, do not infringe the asserted patent.

"We are very pleased with this decision, which again confirmed that Nintendo’s products do not infringe," said Ajay Singh, Nintendo of America’s Director of Litigation and Compliance. "It also confirms that Nintendo continues to develop unique and innovative products while respecting the intellectual property rights of others. Nintendo will defend its products and its innovations, even if it must do so multiple times in different places and over many years."
