“A Pennsylvania company by the name of FlatWorld has filed a patent infringement lawsuit against Apple in the California Northern District Court in San Francisco,” Jack Purcher reports for Patently Apple. “The patent infringement lawsuit concerns Apple’s entire line-up of touch related products.”

Purcher writes, “It’s very difficult to understand how this relates to any of Apple’s iDevices or Magic Mouse for that matter. In my opinion, it’s simply a bizarre stretch.
