Nintendo has prevailed in a patent infringement case at the International Trade Commission, which determined that Nintendo’s DSi and 3DS portables do not infringe on microprocessor patents held by three holding companies.
The complaint, originally brought in July 2012, dealt with patents on microprocessors with variable clock speeds and “high performance, low cost architecture” held by licensing companies Technology Properties Limited LLC, Phoenix Digital Solutions LLC, and Patriot Scientific Corporation since the mid-1990s. But Nintendo responded happily yesterday evening to the commission’s decision that Nintendo’s portable systems do not infringe on the patents.
“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,” Richard Medway, Nintendo of America’s vice president and deputy general counsel said in a statement. “Nintendo continues to develop unique and innovative products while respecting the intellectual property rights of others.”
