You may remember a few months back when Apple sued HTC for patent infringement. The case centered mostly around HTC's Android phones. Long story short, it looked a little grim for the relatively young HTC, though it will still likely take years for the case to run its course. But now HTC is coming out swinging, and has filed a complaint with the International Trade Commission (ITC) against Apple for infringing five of their patents. HTC has asked the ITC to ban imports of the iPhone, iPad , and iPod Touch. This is a common request in these cases.
According to GIzmodo (though not yet confirmed), two of the patents are related to power management, two are for personalized phone dialers, and one is for a dialer with special memory access. Apple threw everything they had at HTC, and by comparison this is small potatoes. It could be HTC is attempting to extract a cross-licensing deal from Apple, or just get them to call it a day. No corresponding federal lawsuit has been filed as of yet, but that could be coming too. We'll keep an eye on this one folks.
