Purpose. According to the patent text, the invention "relates to privacy protection from robots such as drones, cars, and AV recording equipment." The background notes concerns over drones and robots operating over private property, and cites existing drone capabilities such as live-feed video, infrared, heat sensors, radar, and interception of communications. The stated aim is to balance privacy and safety against potential benefits of commercial or private drone, robotics, and smart-vehicle use.
Plain-language scope (from the excerpt). The text describes two example systems:
- A privacy system in which a radio circuit sends a "privacy indication" in a beacon frame, and a movable device receives that beacon frame via its own radio circuit and includes a motor actuator "controlled to comply with the privacy indication."
- A package-delivery system using a storage device and processor on a delivery device. It receives delivery information (delivery address and privacy authentication information to land), transports the package to the address, detects one or more first beacons transmitted by a delivery receptacle, navigates toward that receptacle based on those beacons, and transmits a second beacon to the receptacle. The excerpt cuts off mid-sentence at that second beacon.
Classifications listed include beacon systems (G01S1/00, G01S1/68), UAV types (B64U10/13), jamming/countermeasures (H04K3/00, H04K3/92), anti-jamming of satellite positioning (G01S19/015), and wireless security/privacy (H04W12/02, H04W12/03).
What the excerpt does not establish. It does not provide the full claims, complete description, or figures; the second system's description is truncated; and procedural matters (validity, enforceability, or litigation) are not addressed. The legal-status and assignee entries are expressly listed as assumptions, not 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.
