Patent number / kind: US8904464B1 (application US13/800,573)
Inventor: Ingemar J. Cox
Assignee: Network 1 Technologies Inc (original assignee; listed as current)
Key dates (per the source's own caveats):
- Prior art date / priority date: 2000-09-14 (both stated as assumptions, not legal conclusions)

Purpose / plain-language scope (from the supplied text only): The title identifies the subject matter as a method for tagging an electronic media work so that an action can be performed. The listed prior-art keywords — "electronic device," "work," "information," "user," "media work" — are the only substantive content the excerpt provides about scope, indicating the invention concerns associating information with a media work in relation to a user of an electronic device.
Classification context: The excerpt classifies the patent under H04H60/35 and H04H60/37 (identifying/recognising characteristics of broadcast information, including identifying segments or extracting programme ID) and numerous G06F16 groupings covering information retrieval, multimedia data, query formulation (audio and image), metadata-based retrieval, and geographic/location metadata.
Continuity: The excerpt lists priority relationships to, and from, many related applications (e.g., US09/950,972 via US7058223B2; US11/445,928 via US8010988B2; and numerous later filings such as US8904465B1, US9282359B1, US8656441B1, US8782726B1, US9348820B1).

What the excerpt does not establish: It contains no claims, abstract, or detailed description, so the actual claimed method steps, limitations, and scope are not established. It does not establish validity, enforceability, or patentability, and provides no comparison to prior art. Litigation entries and any legal-status statements are expressly disclaimed in the source as assumptions rather than legal conclusions. Assignee accuracy is likewise not warranted by the source. No further facts should be inferred from this excerpt.

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.
