Apple late Friday responded to Motorola's lawsuit by filing two countersuits of its own. The complaints accuse Motorola of violating six patents primarily relating to multi-touch but also to graphical interfaces. Most of Motorola's currently shipping Android-based devices are covered, including the Droid, Droid 2 and Droid X, as well as the Backflip, Charm, Cliq, Cliq XT, Devour and i1.
