Purpose and plain-language scope (from the excerpted Definitions):
The invention relates generally to a system for receiving a person at an entrance, such as a home or business, though the text states it is not limited to that context.
The described audio-video communication system comprises three main elements:
- A wireless exterior module located proximate an entrance, including a proximity sensor to detect a person, a video camera to record the person's image, a microphone and speaker for audio to/from the person, and a transmitter and receiver for communicating sounds and images.
- A computerized controller disposed in wireless electronic communication with the exterior module via that transmitter and receiver, running a software application.
- A remote peripheral device.
What the excerpt does not establish:
The supplied text is truncated mid-sentence ("the computerize[d]…"). It contains no claims, no full written description, and no prior-art discussion. It therefore does not establish the specific claim scope, the role of the remote peripheral device, the method steps implied by the title, or any validity determination. Per the operating rules, litigation, ownership transfers, validity, and prior art are not addressed here.

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.
