Purpose and plain-language scope

Based only on the supplied text, the patent concerns automating how a device is provisioned and activated. The prior-art keywords given are "service," "network," "agent," "server," and "message," indicating the subject matter involves a network server communicating with an agent on a device via messages to set up or activate service.

Important limitation: The supplied excerpt contains no abstract, no claim text, no detailed description, and no drawings content. It shows only bibliographic and procedural data, family/litigation links, and prior-art keywords. It therefore does not establish the specific claimed steps, the scope of any claim, the technical problem addressed, embodiments, or how provisioning/activation is actually performed. Any statement about what the patent covers beyond the title and keywords would be invented.

Likewise, the excerpt does not establish validity, enforceability, claim construction, or the merits of any listed litigation. The listed litigation entries are procedural references only and are not analyzed here per instructions. Assignee entries reflect recorded reassignments (Headwater Partners I LLC to Headwater Research LLC) but no legal conclusion is drawn.

Not established by this excerpt: abstract, claims, detailed description, figures, cited prior art references, examiner citations, and any substantive technical disclosure.

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.
