Umbra Tech virtual network patent challenged

On April 27, 2026, Unified Patents filed an ex parte reexamination proceeding against 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.
