Purpose. The patent addresses establishing secured communications pathways over an unsecured open network, particularly for server-based (thin client) computing, where applications run on a remote server and only display data and input travel between the user's device and the application server. The stated problem: minimal communications make conventional security difficult, and users should not have to pre-install certificates or software, nor install separate certificates/protocols for each application server.
Plain-language scope. A gateway or authentication server supplies a downloadable mobile authentication and encryption client (e.g., a Java applet) that runs in the user's browser independently of the device's underlying configuration. The server authenticates the user via a user identifier/password (or SecurID, biometrics, etc.), authenticates the client upon execution, and the client encrypts communications with the gateway. A described method: connect to the gateway, authenticate the user, select an application, download the client, establish a secured pathway, and launch the application with data flowing through that pathway. Authentication may use secret keys to generate a session key; the gateway may forward decrypted traffic to a secure application server or re-encrypt it. The "gateway or authentication server" may be discrete or part of the application server itself.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
