Another day, another lawsuit. NovelPoint Tracking (NPT) has sued Apple for patent infringement. The Texas-based company claims Apple's various iDevices infringe on their patent for a method and apparatus for an automatic vehicle location, collision notification and synthetic voice, notes "Patently Apple" (www.patentlyapple.com).

Apple "isn't just being sued for their own iOS location based services but also for facilitating third party location based services on their iDevices," the article adds. The case was filed in the United States Texas Eastern District Court.

NPT appears to be a "patent troll" -- in other words, a company "who enforces patents against one or more alleged infringers in a manner considered aggressive or opportunistic with no intention to manufacture or market the patented invention." The company has also sued Ford Motor, RIM< HP, HTC, Track What Matters and other companies.
