Apple has filed a lawsuit against handheld scanner maker Unova for using technology protected by six Apple patents without permission, reports Bloomberg. Unova’s Intermec unit is using the patented technology in software and scanners that are handheld or mounted on vehicles and used by delivery people or warehouse workers. The suit seeks to bar Unova from selling products that rely on Apple’s innovations. Unova sued Apple and other computer makers last May, claiming infringement of a patented invention to monitor use and recharging of laptop batteries. “It appears to be a tactical response by Apple, filed in response to our lawsuit against them in 2002 for infringement of Unova’s smart battery patents,” Unova spokesman David Brooks said.
