It appears that Nintendo is among a number of parties, including retailers, being sued for alleged patent infringement by Secure Axcess, a company dedicated to “monetization and management of Internet security patents.”

The patent, issued to Secure Axcess in February 2003, covers “a computer providing multiple display capability where one display presents the current document and another display may show a true display of a previously opened document.” In other words, a computer that shows information on more than one screen, like the Wii U with its game pad.

What about the DS? Well, this actually isn’t the first time Secure Axcess has attempted to sue Nintendo for infringement of this same patent. In January, Nintendo was summoned for the Nintendo DS, DS Lite, DSi, 3DS, and 3DS XL.

Nintendo has been sued over other infringement cases in the past, including for the 3D technology in the 3DS, for which Nintendo now pays royalties for each handheld sold. Nintendo won a lawsuit in 2013 that claimed that the Wii Balance Board violated a patent.

The patent is publicly available here. Let us know what you think about these allegations in the comments section.
