US PTAB IP Litigation

Cisco Systems challenged UMBRA Technologies’ ’632 patent on data‑beacon and SD‑WAN innovations. UMBRA’s response argues the cited ’421 patent and ’685 provisional lack the required disclosures and contain cancelled matter, rendering them non‑prior art. The patent owner also asserts the term “data beacon” is a limiting preamble limitation not taught by the prior art.
