Another day, another lawsuit for Nintendo. Their wacky ideas have probably been done in some form or another over the years, and now everyone wants a profitable piece of the action. The latest candidate for a chunk of Nintendo's payroll is John R. Martin, who claims to have patented touch-screen and pointing gaming technology in 2005. One year after the DS was released. Despite being a bit late, the origins of the patent date back to 1995, so it's fair game for the courts now.
This image was submitted with the patent filing, apparently showing a device "switchable between an amusement mode and a gaming or gambling mode." The whole touching thing can be found under "operating a touch screen on a CRT or ICD." But gambling? Looks like that diagram is for someone who hides stuff under the table to cheat at blackjack or roulette.
Nintendo has denied the infringement, while Martin is pursuing another suit against Apple.
