Add one more to the tally of patent lawsuits involving Apple
. This time it's Openwave Systems using the license-by-litigation technique, and it's alleging that multiple devices infringe five of its patents on mobile internet -- including offline email access, cloud computing, and secure server access. The company claims that Apple's iPhone 3G, 3GS and 4, the iPod Touch, both iPads, plus RIM's Blackberry Curve 9930 and the PlayBook all infringe its IP. Apparently, Openwave initially took the pacifist route to persuade Cupertino and Waterloo to pay up, but when its overtures were ignored, it decided upon more aggressive tactics. As others before it, Openwave wants to fight a two front war in the ITC
and federal court, but we'll have to wait and see if the ITC elects to take up the cause. Armchair attorneys can get a gander at all the juicy details at the source below.
