Patent Overview — US11412774B2
Title: "Tobacco mousse"
Assignee: JT International SA (original and current assignee per the supplied record)
Inventors: Michael Plattner, Takashi Hasegawa
Key dates: Priority date 2016-12-29; filing date 2017-12-29; publication of US20190343168A1 on 2019-11-14; granted and published as US11412774B2 on 2022-08-16. Status listed as Active, with an adjusted expiration of 2039-02-08. Application number US16/474,417.
Purpose: The patent addresses the problem of an uneven or inhomogeneous smoking profile in e-cigarettes and similar devices, where flavor experienced across puffs can differ significantly. The stated aim is a product providing a more homogeneous evaporation profile and a more even smoking profile.
Plain-language scope: The disclosure concerns a foam (a "tobacco mousse") comprising a tobacco ingredient containing agent and/or an inhalable agent, an aerosol forming agent, a foam stabilizing agent, and a foam forming agent. The tobacco ingredient and/or inhalable agent is 0.1–33 wt.-% of the foam, and the aerosol forming agent is 10–70 wt.-%. Variants describe foams "essentially consisting of" or "consisting of" those components (plus unavoidable impurities), and a foam forming agent that is preferably a non-protein-containing polysaccharide at less than 20, 10, or 5 wt.-%. Further aspects cover a method of generating an aerosol by heating such a foam without combustion at 150–350°C; a method of forming the foam by mixing under heating, optionally injecting gas, then adding agents and cooling; a method of supplying foam to an aerosol generation apparatus; kits; and packaging. An "open pored foam" (gas pockets interconnected) is defined.

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.
