Purpose: The application "generally relates to data communication networks" and to "systems and methods for fine grain policy driven cookie proxying management, clientless cookie management and techniques for cookie proxying." The stated problem: an enterprise serves clients with differing cookie capability and security configurations, so "a client that is not enabled to use cookies may have difficulty connecting and using the service." The proposed solution lets an enterprise offer services "regardless of their cookie or cookie related security configurations," and "enables a client that is not configured to use cookies to access a server that uses cookies."

Plain-language scope (from the excerpt): An intermediary deployed between client and server "intercepts and modifies transmissions" to compensate for cookie-configuration mismatch. In the described method, the intermediary receives a server response containing a URL and a cookie, "remove[s] the cookie from the response," inserts a unique client identifier into the URL, stores the removed cookie in association with that identifier, and forwards the modified response to the client. On the return path, the intermediary matches the request URL against stored removed cookies, "add[s] the removed cookie" to the request URL, and forwards it to the server. A cookie manager performs matching; name-value pairs may be returned; responses may carry multiple cookies and multiple client identifiers; the unique client identifier may be "a cookie proxy session cookie comprising a portion of the cookie."

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.
