Drama. Rather than leaving well enough alone -- at least long enough for its lawyers to properly enjoy the Independence Day weekend -- Apple has seemingly kicked its ongoing legal battle with Samsung up a notch. According to a filing discovered by FOSS Patents, the perturbed in Cupertino have filed a motion for a preliminary injunction with the US District Court for the Northern District of California. Interestingly, the motion hones in on just four devices: the Infuse 4G, Galaxy S 4G, Droid Charge, and Galaxy Tab 10.1. It's a pretty bold move on Apple's part -- if this thing holds, and it's determined that the aforesaid products may well indeed be infringing on Apple's rights, Sammy could be forced to yank those products from US shelves within a couple of months. If it falls through, however, Apple's entire case will likely take a serious hit. We'd ponder why everyone can't just get along, but at this point, we're guessing the act of forgiveness has become a foreign concept for both parties.
