Purpose and Plain-Language Scope
The patent describes a video surveillance system in which digital video cameras connect through a "camera application module" to a remote terminal — such as a cellular or wireless telephone — over a wireless connection (fixed wireless, Email, or cellular). Cameras run continuously, sending output to a storage device via a controller; stored video is overwritten once capacity is reached. Alarms at individual cameras trigger an alarm message to the user's wireless terminal by call and text message. The user may then call the system and select any camera's output, including sound, and retrieve video from before the alarm (a selectable interval prior to, including, and after the alarm, held in non-volatile event memory). The system also responds to a poll from the remote terminal and transmits frames from a user-selected camera. The specification states full-speed streaming video is not contemplated on 2G (GSM/GPRS), where video is compressed to the available radio bandwidth, and proposes 4G/IEEE 802.16 (OFDMA) networks for streaming video and voice to fixed and mobile subscribers.

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.
