On April 22, 2026, after Unified filed an ex parte reexamination, the Central Reexamination Unit (CRU) granted Unified’s request, finding substantial new questions of patentability on all challenged claims of U.S. Patent 9,628,310, owned and asserted by Atlas Global Technologies, LLC, an NPE and Acacia Research entity. The ‘310 patent is directed to the format of HE LTFs (high efficiency long training fields) for various combinations of HE LTF modes and channel bandwidths in Wi-Fi transmissions. The patent is currently being asserted against HPE, but has been asserted against Arcadyan Technology, Dell, and Vantiva in the past.
