On May 23, 2018, the Patent Trial and Appeal Board (PTAB) instituted trial on all challenged claims in an IPR filed by Unified against U.S. Patent 8,902,770 owned and asserted by Cellular Communications Equipment, an Acacia subsidiary and well-known NPE. The '770 patent, directed to a method for “explicit signaling between a network and the user equipment,” has been asserted in district litigation against such companies as Apple, ZTE, AT&T, Verizon, Sprint, Boost Mobile, and T-Mobile.
