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

U.S. Patent No. 7,614,402 - "Simulated Cigarette"

  • Patent Identification: U.S. Patent No. 7,614,402, "Simulated Cigarette," issued November 10, 2009.

The Invention Explained

  • Problem Addressed: The patent identifies two primary challenges for individuals trying to quit smoking: nicotine addiction and "oral fixation," which is the "comforting feel of a cigarette" that is difficult to replace ('402 Patent, col. 1:18-24). The patent notes that while solutions like nicotine gum exist, little has been done to address the behavioral aspect of oral fixation ('402 Patent, col. 1:25-30).
  • The Patented Solution: The invention is a non-combustible, non-nicotine "pseudo-cigarette" designed to mimic the look and feel of a real cigarette to satisfy a user's oral fixation ('402 Patent, col. 1:38-42). It consists of a cylindrical body with a filter-like end containing a hollow portion. This hollow portion holds a flavoring (e.g., peppermint) that is released into the user's mouth "upon the application of pressure," such as by biting or inhaling, thereby providing a pleasant taste and reducing the urge for a real cigarette ('402 Patent, Abstract; col. 2:48-53). Figure 2 provides a cut-away view showing the flavoring means (25) inside the hollow portion (24) of the filter member (20).
  • Technical Importance: The invention's stated purpose is to provide a "healthy, smoke-free replacement" that directly addresses the psychological dependency of holding and using a cigarette, an aspect distinct from purely chemical-based cessation aids ('402 Patent, col. 1:61-63).

Key Claims at a Glance

  • The complaint asserts at least independent Claim 1 (Compl. ¶10).
  • The essential elements of independent Claim 1 are:
    • a cylindrical member having a first and second portion;
    • a filter member formed at an end of the first portion, shaped to be comfortably held between a user's lips;
    • an opening within an end of the filter member;
    • a hollow portion formed within the filter member;
    • a flavoring means placed within the hollow portion, capable of dispersing flavoring through the opening and into a user's mouth upon the application of pressure to the filter member;
    • wherein the hollow portion comprises a plastic tube which extends through the filter member for containing the flavoring means.
  • The complaint does not explicitly reserve the right to assert dependent claims, but the prayer for relief requests a finding of infringement of "one or more claims" (Compl., Prayer for Relief ¶A).

III. The Accused Instrumentality

Product Identification

  • The complaint identifies the "WOW Vapor" as an exemplary accused product, and more broadly refers to Defendant's "cigarette-like devices" (Compl. ¶¶11-12).

Functionality and Market Context

  • The complaint alleges that the accused products are "cigarette-like devices" that Defendant manufactures, imports, offers for sale, and sells (Compl. ¶11). The complaint does not provide any specific technical details regarding the structure, components, or mechanism of operation of the WOW Vapor product. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint states that a claim chart comparing Claim 1 of the ’402 Patent to the Accused Product is attached as Exhibit B (Compl. ¶13). However, this exhibit was not included with the filed complaint. The infringement theory is therefore based on the narrative allegations in the complaint.

The complaint alleges that Defendant’s "cigarette-like devices," including the WOW Vapor, infringe at least Claim 1 of the ’402 Patent (Compl. ¶11). The complaint quotes the entirety of Claim 1 and asserts that the Accused Products meet its limitations (Compl. ¶10). Without the claim chart or a more detailed technical description of the accused product, a specific element-by-element analysis of the infringement allegations is not possible. The core of the infringement allegation is that the Defendant's products are "simulated cigarette[s]" that fall within the scope of the patent's claims (Compl. ¶10).

The lack of a claim chart or specific factual allegations mapping product features to claim elements raises the question of whether the complaint meets the pleading standards established by Twombly and Iqbal.

V. Key Claim Terms for Construction

  • The Term: "flavoring means... capable of dispersing flavoring... upon the application of pressure to said filter member"

    • Context and Importance: This term is central because it defines the mechanism of action. The patent describes "pressure" as including external force from a user's lips or hands, as well as the application of a vacuum through inhalation ('402 Patent, col. 3:15-22). Practitioners may focus on this term because modern vaporizers typically use a heating element (atomizer) activated by inhalation or a button to vaporize a liquid, which may or may not be considered "application of pressure" in the manner contemplated by the patent. The construction of "pressure" will be critical to determining if the claim reads on electronic vaporization technology.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The specification explicitly includes "application of a vacuum, or inhalation" as a technique for releasing the flavor ('402 Patent, col. 3:20-22). A party could argue that the suction required to activate an electronic vaporizer falls within this definition.
      • Evidence for a Narrower Interpretation: The patent’s embodiments describe a passive system where pressure releases a pre-existing flavoring from a medium like a "flavored tablet or powder" ('402 Patent, col. 3:26-30). A party could argue this implies a mechanical release, not the electronic heating and phase change (vaporization) of a liquid that occurs in modern e-cigarettes.

  • The Term: "a plastic tube which extends through said filter member for containing said flavoring means therein"

    • Context and Importance: This is a key structural limitation. Practitioners may focus on this term because its interpretation will determine whether the architecture of a modern vape cartridge or tank can be considered equivalent to the specific structure claimed.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: A party might argue that a modern e-cigarette cartridge is functionally a "plastic tube" that "contain[s] said flavoring means" (the e-liquid) and that the mouthpiece assembly it connects to is a "filter member."
      • Evidence for a Narrower Interpretation: Figure 2 of the patent illustrates a distinct "plastic tube (34)" that is situated inside and "extends through" a separate "fibrous member (32)" that constitutes the "filter member (20)" ('402 Patent, col. 2:53-54, col. 3:9-14). A party could argue this requires a specific nested structure that is absent in typical integrated vape cartridges or pods.

VI. Other Allegations

  • Indirect Infringement: The complaint does not contain allegations of indirect infringement.
  • Willful Infringement: The complaint does not contain allegations of willful infringement or any facts suggesting Defendant had pre- or post-suit knowledge of the ’402 Patent.

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

  1. A core issue will be one of definitional scope: can claim terms rooted in the context of a passive, non-electronic, mechanical device from 2005—such as "flavoring means...dispersing...upon the application of pressure" and "a plastic tube which extends through said filter member"—be construed to cover the components and heat-based vaporization mechanism of a modern electronic cigarette like the accused WOW Vapor product?

  2. A key evidentiary and procedural question will be whether the plaintiff can provide sufficient factual evidence to support its infringement allegations. Given the conclusory nature of the complaint and the absence of the referenced claim chart, the case may turn on what discovery reveals about the specific structure and operation of the accused products and whether those facts can plausibly map onto the patent's claim limitations.
