MagnaCross LLC’s second round of filing in its only litigation campaign includes twice as many suits as the original round of filing from October 2014. Twenty new defendants, including wireless providers AT&T, Sprint, T-Mobile, and Verizon, as well as mobile device manufacturers Acer, ASUS, Fuhu, Kyocera, Panasonic, and Razr have been added to the campaign. As in the first round, the new complaints assert a single patent, 6,917,304, which relates to wireless data transmission. The accused products in the campaign are smartphones and tablets made or sold by the defendants. In particular, the capability to transfer data between a smartphone or tablet and a smart device, such as an activity tracker or smartwatch, is at issue in the suits.
