Nintendo has won a patent infringement case in a U.S. District Court in Texas. The case was brought in February 2009 by Wall Wireless, LLC, which claimed that the Nintendo DS and Nintendo DSi systems infringed a patent. Wall Wireless is a company whose primary business is enforcing patents. The court dismissed the case on May 19, 2014, after the United States Patent and Trademark Office canceled all the patent claims Wall Wireless was relying on in its case.

This dismissal follows a decision by the Japanese Patent Office, which also found that Nintendo’s products do not infringe Wall’s Japanese patents.
