II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 11,744,256 - "Device and method for Imparting Smoked Flavors to Beverages and Foodstuffs"

• Patent Identification: U.S. Patent No. 11,744,256, "Device and method for Imparting Smoked Flavors to Beverages and Foodstuffs," issued September 5, 2023.

The Invention Explained

• Problem Addressed: The patent describes prior art smoking devices as cumbersome and limited. For example, "bartop" smokers using a glass box can be difficult to clean and can impart unwanted smoky residue to the outside of a drinking glass, while other methods require smoking an empty glass before a beverage is added, which is less effective for flavor infusion (’256 Patent, col. 1:14-37).
• The Patented Solution: The invention is a compact device designed to sit directly on top of a drinking glass. It comprises an upper "fuel chamber portion" to hold combustible material (like wood chips) and a lower "conduit portion" that extends down into the glass. When the fuel is ignited, the device's structure is designed to facilitate a downward flow of smoke through the conduit and out of one or more apertures, directly infusing the beverage or foodstuff below with smoke (’256 Patent, Abstract; col. 6:27-34).
• Technical Importance: The claimed design provides a self-contained, efficient, and direct method for infusing smoke into a beverage that is already in a glass, intended to overcome the shortcomings of prior art systems (’256 Patent, col. 1:38-46).

Key Claims at a Glance

• The complaint asserts infringement of claims 1-19, with independent claims 1, 9, and 10 being identified (Compl. ¶¶ 21, 52). Claim 1 is detailed as exemplary.
• Independent Claim 1 recites the following essential elements:
  • A base having a fuel chamber portion at its upper end and a conduit portion at its lower end.
  • The fuel chamber portion includes an upper wall and a floor with an opening.
  • The fuel chamber portion is oriented to hold fuel.
  • The conduit portion is disposed below the floor and has a channel through it.
  • The structure is arranged so that when fuel is ignited, the channel facilitates a downward flow of smoke from the fuel chamber through at least one aperture in the wall of the conduit portion.
• The complaint reserves the right to assert all claims, including dependent claims (Compl. ¶¶ 31, 52).

III. The Accused Instrumentality

Product Identification

• The complaint identifies the "Accused Products" as various smoker devices for imparting smoked flavors to beverages and foods, sold by the Doe Defendants on Amazon.com and other online platforms (Compl. ¶¶ 5, 22). An exemplary product is the "Cocktail Smoker Kit Including Torch & 4 Flavors Wood Chips..." from an Amazon storefront corresponding to Defendant Doe#68 (Compl. ¶28).

Functionality and Market Context

• The Accused Products are described as kits that include a smoker device, often with a torch and wood chips, which are placed on top of a cocktail glass to infuse the drink with smoke (Compl. ¶28). The complaint alleges that these products are manufactured in China and sold through numerous "Infringing Webstores," creating a "flood" of infringing products in the online market that damages the Plaintiff's business for its own "FOGHAT" branded products (Compl. ¶¶ 15, 18). An annotated image from an accused product listing shows a device with an upper section for fuel and a lower section that sits inside a glass (Compl. ¶28, p. 9).

IV. Analysis of Infringement Allegations

’256 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
a base having a fuel chamber portion at its upper end and a conduit portion at its lower end...	The accused device is alleged to be a base with an upper fuel chamber and a lower conduit portion. An annotated image of an accused product illustrates the alleged "base having a fuel chamber portion and a conduit portion" (Compl. ¶28, p. 9).	¶28	col. 6:19-21
the fuel chamber portion comprising an upper wall portion defining a perimeter edge of the fuel chamber portion and a floor defining a bottom end...	The accused device's fuel chamber is alleged to have an upper wall and a floor with an opening. A second annotated photograph identifies the "upper wall portion" and the "floor extending from the upper wall portion to an opening" (Compl. ¶28, p. 9).	¶28	col. 6:21-24
wherein the fuel chamber portion is oriented to hold fuel...	The accused device's upper portion is shown holding wood chips for ignition. A product usage diagram shows a user igniting wood chips in the fuel chamber with a torch, which the complaint maps to this element (Compl. ¶28, p. 10).	¶28	col. 6:25-26
wherein the conduit portion is disposed below the floor and comprises a channel through the conduit portion...	The accused device has a lower portion extending below the fuel chamber floor, creating a channel for smoke.	¶28	col. 6:27-29
so that, when the fuel in the fuel chamber portion is ignited, the channel facilitates flow of smoke down-ward from the fuel chamber portion through at least one aperture that extends from the channel space through a wall of the conduit portion.	When the wood chips are ignited, smoke is allegedly channeled downward through the conduit and out of side apertures into the glass. A four-panel instructional graphic depicts smoke flowing downwards into the glass, which the complaint alleges satisfies the limitation that "the channel facilitates flow of smoke down-ward" (Compl. ¶28, p. 10).	¶28	col. 6:29-34

Identified Points of Contention

• Scope Questions: The case may raise questions about the scope of "facilitates flow of smoke down-ward." A court will need to determine whether this functional language requires a specific structure that actively directs or enhances downward smoke flow, or if it is met by any device where smoke simply passes from a higher fuel chamber to a lower exit point.
• Technical Questions: The infringement allegations rely on visual evidence from online product listings (Compl. ¶28). A key technical question will be whether the actual physical construction of the numerous Accused Products, particularly the internal geometry and fluid dynamics, performs the specific function of channeling smoke downward through an aperture as required by the claim.

V. Key Claim Terms for Construction

The Term: "conduit portion"

• Context and Importance: This term defines the core structural feature that allegedly directs smoke into the beverage. The infringement case hinges on the accused devices having a structure that can be properly characterized as a "conduit portion" that is distinct from, and disposed below, the "fuel chamber portion." Practitioners may focus on this term because its construction will determine how closely the accused products must resemble the patent's drawings to infringe.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claims do not limit the shape of the "conduit portion." The specification states that while embodiments show a cylindrical shape, the device can be formed in "square, rectangle, elliptic, customized... or any other shapes that can fall within the claims," which may support a construction not limited to a simple tube (’256 Patent, col. 3:9-13).
  • Evidence for a Narrower Interpretation: The patent figures consistently depict the "conduit portion" (108) as a distinct cylindrical structure extending downward from the "floor" (112) of the fuel chamber (’256 Patent, Figs. 1, 3, 5A). A defendant could argue these consistent depictions limit the term to this specific structural arrangement.

The Term: "facilitates flow of smoke down-ward"

• Context and Importance: This functional limitation is central to the patent's novelty argument over prior art. Proving infringement requires showing that the accused device is not just a passive container for burning fuel but is actively structured to achieve this downward flow. The outcome of the case could depend heavily on whether this term is given a broad or narrow meaning.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: A plaintiff may argue that the "so that" clause means that any claimed structure (a base with an upper fuel chamber and a lower conduit with an aperture) that results in downward smoke flow meets the limitation, without requiring any additional "facilitating" mechanism.
  • Evidence for a Narrower Interpretation: The specification mentions that a "rising angle for aperture 114 channels can enhance the flow of smoke," suggesting that "facilitates" implies more than passive diffusion and may require a specific design feature intended to promote the downward flow (’256 Patent, col. 5:14-17).

VI. Other Allegations

Indirect Infringement

• The complaint alleges active inducement of infringement under 35 U.S.C. § 271(b). The factual basis for this claim is the allegation that Defendants provide the Accused Products with instructions, such as the "How To Use" diagrams, that instruct and encourage customers to operate the devices in a manner that directly infringes the patent's claims (Compl. ¶¶ 28, 34).

Willful Infringement

• Willfulness is alleged based on Defendants having become aware of the patent-in-suit and continuing their infringing activities (Compl. ¶39). The complaint states this on "information and belief" and alleges that Defendants have "refused to cease selling products" after becoming aware of the patent (Compl. ¶39).

VII. Analyst’s Conclusion: Key Questions for the Case

• A primary procedural hurdle will be one of party identification and discovery: given that the suit is filed against over 160 unidentified "Doe" defendants alleged to be foreign e-commerce sellers using fictitious names, a threshold challenge for the Plaintiff will be successfully identifying these entities, establishing personal jurisdiction, and obtaining the necessary discovery to prove infringement on a defendant-by-defendant basis.
• A central legal issue will be the claim construction of the functional limitation "facilitates flow of smoke down-ward." The case will likely turn on whether this term is construed to require a specific structure that actively promotes or enhances downward airflow, or if it is met by any device structured with a fuel source positioned above a lower exit point through which smoke can pass.
• A key evidentiary question will be one of structural correspondence: beyond the marketing images provided in the complaint, can the Plaintiff produce evidence demonstrating that the actual, physical construction of the various accused products—specifically the internal geometry of the "base," "floor," "conduit portion," and "aperture"—maps directly onto the structural limitations recited in the asserted claims?
