Patent Overview: US12075943B2 — "Cooking device and components thereof"
Bibliographic data (from source): Application US18/186,671; filed 2023-03-20; granted/publication date 2024-09-03; priority date listed as 2019-07-15; anticipated expiration 2040-07-15; legal status "Active"; current/original assignee SharkNinja Operating LLC; inventors Christopher T. Martin, Thomas Guerin, Roger Neil Jackson, Joshua D. Anthony, Kerry Schwarz, and Michaela Dubeau. The family is flagged as having litigation; no details are provided here.
Purpose: Per the "Definitions" section, embodiments relate generally to a cooking system—more specifically a countertop cooking system operable in a plurality of distinct cooking modes. Classifications include A47J27/00, A47J27/12, and A47J37/06, notably A47J37/0641 ("air fryers": small-size cooking ovens with electric heating elements and forced air circulation).
Plain-language scope (as excerpted): The system includes a housing with at least one internal compartment and a cooking container receivable therein, a cooking volume defined inside the container, and a heating element associated with the internal compartment. Features recited include a container bottom surface angled upwardly, non-orthogonal to the back wall, and a container taller at the back than the front; a removable insert at least partially defining the cooking volume, with a generally horizontal food support surface offset from the container bottom by a clearance that varies over at least one dimension; an insert protrusion fitting a channel in the container bottom; an air duct separate from the cooking volume defined between the insert and container (including between a blocking wall and the container back wall); and an air movement mechanism with a fan housing (first and second inlets, an outlet), a fan wheel with first and second impeller-blade portions, arranged vertically above the cooking volume/container, rotatable about a relatively horizontal axis, with outlet aligned to the air duct.

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.
