Nintendo has won a patent infringement lawsuit filed back in 2009 by Wall Wireless LLC concerning the DS and DSi handheld gaming systems. In February of 2009, Texas-based Wall Wireless LLC sued Nintendo claiming that its DS and DSi handhelds violated a patent it held related to wireless communication technology.
Wall Wireless is what is commonly called a "non-practicing entity," meaning that it has the rights to patents, which it often uses to sue other companies for infringing upon. Both the Japanese Patent Office and the United States Patent and Trademark Office have ruled that Nintendo's systems did not infringe Wall's patents.
"We are very pleased to see the US case dismissed, and also to have the Japanese Patent Office confirm that Nintendo does not infringe Wall's Japanese patents," Nintendo of America's vice president and deputy general counsel Richard Medway said. "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."
Nintendo is often the target of patent lawsuits, but most of the time it ends up winning these battles. The latest lawsuit filed against Nintendo is from Electronics manufacturer Philips, who sued the company claiming that it is willfully selling products (Wii, Wii U) that infringe on two of its patents related to motion-sensing controls. It is seeking damages in addition to a ban on the sale of multiple Nintendo products including Wii, Wii Remote, Wii U and Wii U GamePad.
