On June 26, 2026, two months 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 (1-20) of U.S. Patent 12,452,192, owned and asserted by Umbra Technologies Ltd. The ’192 patent is generally directed to virtual network systems where a control server sends a ranked list of access point servers to an endpoint. The endpoint device then uses this ranked list to select the access point server to which it will build a tunnel to the network. It has been asserted against Zscaler.
