Purpose / plain-language scope: The supplied excerpt identifies the invention only as a "fluid dispersion assembly." Its classifications place it as spraying/atomising apparatus that discharges liquid or other fluent material from two or more sources (e.g., liquid and air), with a container supplying the fluent material to a discharge device, and with an atomising fluid (gas) supplied to that discharge device. Related classifications cover air disinfection, sterilisation, or deodorisation using sprayed or atomised substances, dispensing/storing means for active compounds, and apparatus for controlling air treatment. The excerpt's own prior-art keywords are "fluid," "diffusion," "assembly," "chamber," and "fluid dispersion." Beyond this classification-derived description, the excerpt does not set out the actual claims, so the precise claimed scope is not established here.

What the excerpt does not establish: It does not reproduce any claims, the abstract, or the written description, so claim scope, claim limitations, and embodiments cannot be determined from it. It does not establish inventorship or ownership as legal conclusions, does not characterize prior art substantively, and does not determine validity, enforceability, or infringement. The priority date and legal status are expressly flagged in the source as assumptions rather than legal conclusions. Related family members and later filings are listed (e.g., US9126215B1, US10583449B1, US16/154,373), but the excerpt does not explain their relationship or content. Litigation and other proceedings referenced in the source are outside the scope requested and are not analyzed 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.
