Purpose (plain language). The patent addresses a stated problem: bulletin-board event listings force consumers to sift through hundreds of events, and mailing lists deliver notices that are often irrelevant or that omit events of interest. The disclosed system instead tracks the media content a consumer accesses, purchases, views, or otherwise consumes, and uses that history to notify the consumer of upcoming events likely to interest them.
Scope (plain language, from the supplied text). A consumer profile stores a consumer location and consumption information identifying media content items the consumer requested. An event database stores upcoming events, each with an event location and event data associating the event with media content items. When a consumer requests a media content item (e.g., to render a song or video), the system stores interest data, determines whether the item is associated with an event, and transmits a notification of that event based on the consumer's location and interest data. A user interface module performs the notification, and a graphical user interface displays event data. Aspects are claimed as methods (notifying consumers; recommending events), a system (first datastore of media content items, second datastore of events, third datastore of consumer profiles), and a computer-readable medium encoding instructions.

All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
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.
