Patent Overview — US 7,193,644 B2
Title: Automated audio video messaging and answering system
Patent number / application: US 7,193,644 B2; Application US 10/682,185
Inventor: Ronald Carter
Original assignee: Revolutionary Concepts, Inc. (Google Patents lists current assignee as SB IP Holdings LLC)
Key dates (as listed): Priority date 2002-10-15; filed 2003-10-09; first published as US 2005/0285934 A1 on 2005-12-29; granted 2007-03-20. Legal status shown as "Expired – Lifetime," with an adjusted expiration of 2024-10-26.
Purpose: The text describes a system "for monitoring and interacting with a visitor at a residence or business," specifically "detecting the presence of a visitor, interactively communicating therewith at a heightened level of security, enabling automated entry, and generally enhancing and personalizing the overall process of receiving a visitor." It aims to improve "messaging, communication, security" and save time for both visitor and system provider.
Plain-language scope (from the excerpt): The system pairs an exterior unit with an interior unit for visitor detection, two-way audio/video communication, screening (secretly monitoring a message as it is left), messaging, and automated entry. The background criticizes prior devices that lacked intercom capability, lacked screening, made owner interaction non-intuitive or not hands-free, limited the visitor to a single option, were tape-based with custom wiring, or depended on a telephone line so a visitor could not leave a message while the phone was in use. The excerpt also discusses prior-art references, including U.S. Pat. Nos. 5,406,618 (Knuth et al.) and 5,657,380 (Mozer).
What the excerpt does not establish: It omits the full claims, detailed description, and drawing descriptions; therefore no statement can be made here about specific claim limitations, claim count, inventorship beyond the named inventor, or the exact hardware/software architecture. The assignee and legal-status entries are the source's own listings and are not independently verified. No litigation, ownership-transfer, validity, or prior-art analysis is offered.

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.
