MyCena holds granted patents in the United States and Europe covering the core credential control mechanism: central generation, encrypted distribution, invisible injection at the point of authentication, and zero user knowledge of credential content.

The patent matters for two practical reasons. First, it confirms technical specificity — this is an examined, granted mechanism, not a policy claim or a marketing assertion. The credential physically cannot reach the user because the architecture prevents it, and that mechanism has been reviewed and validated. Second, it means no other vendor can replicate this architecture without licensing the patent. The consistency of the technical standard across MyCena deployments is architecturally enforced, not organisationally dependent.
