Nintendo defeats non-practicing entity in global patent fight

In February 2009, Wall Wireless, LLC initiated a patent infringement case against Nintendo. But today, Nintendo announced that the court dismissed the case after the United States Patent and Trademark Office canceled all the patent claims Wall Wireless was relying on in its case.

Wall Wireless, LLC primarily enforces patents, for those unaware. The company claimed that the DS and DSi family of systems infringed a patent.

US District Court Dismisses Case

REDMOND, Wash.–(BUSINESS WIRE)– 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.

“We are very pleased to see the U.S. case dismissed, and also to have the Japanese Patent Office confirm that Nintendo does not infringe Wall’s Japanese patents,” said Richard Medway, Nintendo of America’s vice president and deputy general counsel. “Nintendo vigorously defends patent lawsuits and other proceedings when we believe we have not infringed another party’s patents. It does not matter where such cases are filed or if it takes more than five years to vindicate our position. Nintendo continues to develop unique and innovative products while respecting the intellectual property rights of others.”
