Patent Overview — US 6,452,932 B1
Title: Method, system and apparatus for telecommunications control
Patent number: US 6,452,932 B1
Application number: US 09/499,874
Inventor: Joseph Michael Christie
Assignee (original and current, per the listed data): Sprint Communications Co LP
Priority date: 1994-05-05
Filing date: 2000-02-07
Publication/grant date: 2002-09-17
Legal status listed: Expired – Lifetime; anticipated expiration 2014-05-05
Purpose and plain-language scope:
The patent is directed to controlling telecommunications. The supplied text does not include the abstract, specification, or full claim set, so the scope can be described only from the available metadata and classification. The prior-art keywords listed are: message, processing, switch, ccp, select — indicating subject matter concerning processing messages and selecting/controlling switching functions through a processing component (the "ccp" term appears as a prior-art keyword, but the excerpt does not define it).
The classification data places the disclosure in:
- H04L45/00 — routing or path finding of packets in data switching networks
- H04J3/12 and H04J3/125 — time-division multiplex details, including arrangements for calling or supervisory signals, where a channel or synchronisation pulse also carries monitoring/supervisory signals
- H04J3/247 — ATM or packet multiplexing
- H04L49/25 — routing or path finding in a switch fabric
Taken literally, these classifications describe a packet/ATM and time-division multiplexed communications environment in which control, supervisory signalling, message processing, and switch-fabric routing are coordinated — but the excerpt alone does not establish which of these the claims actually cover.

What the excerpt does not establish:
It does not reproduce the claims, abstract, or detailed description, so the precise claimed method, system, and apparatus are unknown. It does not establish validity, enforceability, claim interpretation, or the content of any prior art. The "ccp" keyword is undefined here. All date, status, and assignee statements are expressly labelled in the source as assumptions rather than legal conclusions.

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.
