Patent Overview: US8085796B2
Title: Methods, systems, and products for virtual personalized networks
Patent number: US8085796B2 | Application: US12/126,137 | Publication (grant): 2011-12-27 | Earlier publication: US20080232295A1 (2008-09-25)
Inventor(s): Barrett Morris Kreiner; Donna K. Hodges; Jonathan M. Peterson
Assignee (original, per source): AT&T Intellectual Property I LP (with an assignment recorded to Bellsouth Intellectual Property Corporation; later reassignments also listed). The current assignee listed is Iot Innovations LLC, though the source states listed assignees "may be inaccurate" and that Google has not analyzed or warranted the list.
Dates: Priority date 2002-11-27; filing date 2008-05-23; granted 2011-12-27. Legal status: Expired – Lifetime, expiration adjusted to 2025-04-26 (status is an assumption, not a legal conclusion).
Classifications: H04L12/28, H04L12/2856, H04L12/2898, H04L12/4604, H04L63/105, H04L67/04, H04L67/63, H04L9/40, H04L67/568, among others.
Purpose and plain-language scope: The source describes a "virtual personalized network" relating to data switching, network path configuration, subscriber equipment, multiple levels of security, and routing of service requests based on request content or context. The recurring prior-art keywords are "data," "communications device," "personal digital," "digital gateway," and "network." Working only from the supplied excerpt, the claimed subject matter appears to concern routing and serving requests across networks for personalized/portable devices, with security-level and access control aspects.
What the excerpt does not establish: The excerpt contains no claim text, no abstract, no detailed description, and no cited prior-art references, so it cannot support any statement about the scope of particular claims, the specific technical mechanisms disclosed, or validity. The listed classifications and prior-art keywords are indexing metadata, not claim language. Litigation entries and ownership transfers appear only as source metadata and were not researched, as instructed.

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.
