Patent Overview — US10583449B1
Title: Fluid dispersion assembly
Patent number: US10583449B1 (application US16/154,373, filed 2018-10-08; granted/published 2020-03-10)
Assignee: Air Esscentials Inc (original and current assignee per the source). Inventors: Marc T. Levy, Craig Huck, Steven Semoff.
Priority date: 2012-08-29 (stated as an assumption, not a legal conclusion). The source also lists external priority claims from US13/838,634 (2013-03-15), US14/844,650 (2015-09-03), and US15/353,951 (2016-11-17). Anticipated expiration: 2033-03-15. Status: Active.
Purpose: According to the source's "Definitions" section, the invention "relates generally to the field of dispersion of various fluids including, but not limited to, fragrant oils, essential oils, odor neutralizers, disinfectants, e.g., triethylene glycol, air sanitizers, and the like, into a generally enclosed airspace."
Plain-language scope: The supplied text identifies the subject matter as a "fluid dispersion assembly" and lists prior-art keywords: fluid, assembly, diffusion, fluid dispersion, chamber. Classifications place it in spraying/atomising apparatus (B05B), specifically apparatus discharging liquids or fluent materials from two or more sources (e.g., liquid and air), with a container supplying material to a discharge device and an atomising fluid supplied to that device, including hand-carried or container-mounted arrangements; and in A61L9/14 (disinfecting, sterilising, or deodorising air using sprayed or atomised substances). This indicates a device for dispersing fluent material into air, but the excerpt does not supply the actual claim language.
What the excerpt does not establish: It contains no claims, no written description, no drawings, and no abstract beyond the brief definition above. It therefore does not establish the specific structural elements, claim limitations, or metes and bounds of the patented subject matter. The source notes litigation and PTAB-related data, which is outside the scope requested here and is not analyzed.

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.
