Besides the HTC One and the HTC DROID DNA, other models mentioned in the complaint include the 2012 series of HTC One phones like the HTC One X and the HTC One X+. The Nokia patents cover technology for video processing, internal smartphone design and radio transceiver technology. Over the last year, Nokia has accused HTC of infringing on over 50 of its patents in suits that have been filed with German and U.S. courts.
Last month, Nokia filed a suit against HTC in a San Diego court alleging that HTC infringed on three separate Nokia patents for a "terminal, method and computer program product for interacting with a signalling tag." Nokia alleges that HTC uses this patent in ten smartphones including the Facebook Home powered HTC First and the HTC One.
