Broadband iTV, Inc. (BBiTV) has added a Western District of Texas suit against Amazon (6:20-cv-00921) to the cases that it filed in that district against AT&T (DirecTV) (1:20-cv-00717, 6:19-cv-00714), and DISH Network (6:19-cv-00716) there in December 2019. Three of the six patents asserted against Amazon generally concern the playback of on-demand TV content over the Internet, while the other three are broadly directed to various aspects of an interactive program guide offering hierarchical navigation. BBiTV targets Amazon’s video-on-demand streaming products, including various Fire-branded set-top boxes and streaming devices, as well as the Amazon Prime Video app for iOS and Android.
