ZTE is the latest defendant to be added to Orlando Communications LLC’s litigation campaign. The Acacia subsidiary filed three suits this week, each pairing ZTE as a codefendant with AT&T, Softbank (Sprint), or T-Mobile. Orlando Communications alleges that certain tablets, smartphones, and WiFi hotspots, manufactured by ZTE and sold by the carrier defendants, infringe two patents related to cellular network data transfer and error correction (5,687,196, 6,009,553).

After suing the majority of mobile device manufacturers in June 2014, Orlando Communications is now targeting Samsung. The four suits accuse Samsung, along with a wireless carrier, AT&T, Sprint, T-Mobile, or Verizon, of infringing two patents asserted in Orlando’s litigation. The Acacia Research subsidiary has asserted the patents-in-suit in each of its 19 cases, and the asserted patents relate to managing and transferring data over a communication system (5,687,196, 6,009,553). Samsung’s handsets are accused of infringing the patents-in-suit; the wireless carriers are accused of selling the infringing handsets to customers in their service networks.

Acacia subsidiary Orlando Communications filed 17 patent infringement suits in two days against a group of electronics manufacturers and wireless carriers. Each litigation pairs a manufacturer with a carrier: HTC, Huawei, Kyocera, LG, Motorola, or Pantech with AT&T, Sprint, T-Mobile, or Verizon. Orlando Communications alleges defendants are infringing two patents related to determining the range of radiofrequency signals and encoding and transmitting data over a communications link (5,687,196, 6,009,553). Tablets, smartphones, and “other 3G and 4G voice/data mobile units” manufactured and sold by defendants are the accused products. It does not appear that the ‘196 and ‘553 patents were involved in any litigation before they were assigned to Orlando.
