REDMOND, Wash., Feb. 19, 2014 – Nintendo has won a patent infringement case at the International Trade Commission. The case was brought by Technology Properties Limited LLC, Phoenix Digital Solutions LLC and Patriot Scientific Corporation, all of which are patent-licensing companies. The commission confirmed that the Nintendo 3DS and Nintendo DSi systems do not infringe the asserted patent.
“We are very pleased with the commission’s determination, which confirmed the judge’s finding that Nintendo’s products do not infringe the asserted patent,” said Richard Medway, Nintendo of America’s vice president and deputy general counsel. “Nintendo’s track record demonstrates that we vigorously defend patent lawsuits, including cases in the ITC, when we believe we have not infringed another party’s patent. Nintendo continues to develop unique and innovative products while respecting the intellectual property rights of others.”
